Easy Ways Anyone Can Save Electricity

Some people believe that the only way to really save electricity it to go out and buy all new appliances that are more energy efficient. While this will certainly help, it is far from the only way to get the job done.

Saving electricity can actually be done without spending a single penny. It’s all about how you use it, specifically, how efficiently you are using it. So let’s look at some free ways to save electricity:

  1. Set your fridge to 40 degrees and freezer to 32 and no lower.

  2. Only open your fridge when you are actually going to get something out of it.

  3. When cooking, use the microwave or toaster oven rather than the large oven.

  4. Turn off lights when you don’t need them.

  5. Open drapes and shades for natural (and free) light during the daytime.

  6. Stop washing clothes and dishes with hot water.

  7. Set your a/c 2 degrees higher than normal

  8. Unscrew light bulbs in fixtures where multiple bulbs are located to only use what you need.

  9. Unplug appliances that aren’t in use.

  10. Hang clothes out to dry if weather permits.

See? There’s 10 absolutely free ways to start saving electricity. Now, if you want to take it a little bit further without having to shell out for brand new appliances, you could get an electric saver unit installed in your home. It will seriously help to reduce the amount of electricity that gets wasted in your home and can lower bills by around 15% all on its own. It can pay for itself in a couple of months and will really help you to start saving power.

No matter how you go about it, saving electricity is a great way to help yourself financially, and help the environment.

The Reasons We Conserve Energy

We’ve all heard of energy conservation and can mostly gather that it must be somewhat important. But why exactly is that? Is it just so that one can save some money on electricity or gas? Well, that is a factor and a benefit of energy conservation. But it’s far from the full picture. Aside from direct personal benefit, there is also an environmental aspect to this.

Let’s take a “popular” one: carbon dioxide emissions. Currently, the way most electricity is generated is through the burning of fossil fuels. This produces a lot of byproducts, the least of which is CO2, which can have a detrimental effect on our atmosphere.

When you conserve electricity, you are helping to reduce the amount of fossil fuels that must be burned as demand is lessened. This results in lower emissions.

Another benefit is the lessened environmental impact caused by having to dig for those fossil fuels. Landscapes and habitats are destroyed in order to make way for dig and drill sites. Less demand means less habitat destroyed.

Next comes fuel. Every time you drive your car (unless it’s electric) you are personally contributing to the CO2 in the atmosphere. Any way you can cut down on emissions helps, be it carpooling, taking public transportation or just getting a more fuel efficient car. If you need more motivation, consider that gas prices will only continue to rise in the coming years.

So you see, it’s more than just personal savings. It’s about ensuring that our planet and all of the various forms of life living upon it, stay healthy. The hard truth is that if we as a species don’t do something to change our “polluting ways”, the lives of our grandchildren will be different than our own. Let’s give them a better chance and do something to protect our own environment from ourselves.

Conserving Energy With Specific Appliances

We all know that it’s important to save energy, not just for our own benefit (lower power bill) but also for the planet as it helps to reduce emissions. And while there are plenty of techniques for saving energy regarding air conditioning, water heating and lighting, that still leave a lot of other appliances and devices to optimize.

So give yourself a little bit of electric bill help with the appliance-specific tips below:

Computers - Saving on computing is pretty easy as many operating systems will help you do it. Setting your computer to sleep after inactivity is one good way. Hibernation mode is even better. You may remeber to turn your monitor off when you leave your desk, but what about your speakers? Finally, if you can opt for a laptop instead of a desktop, that will save the most energy.

Refrigerators - THe first thing you want to do here is ensure that the temperature isn’t set too low. 40° for the fridge and 32° for the freezer is good enough to keep food fresh. Also, every time you open the door to the fridge, you’re letting cold air out and this makes the unit have to work much harder, so only open it when you really need something.

Entertainment Appliances - Most modern televisions, disc players and stereos never actually turn completely off. You can tell by looking at them as there will usually be a little light still on somewhere. You can easily plug all of these devices into a power strip and then just use the switch to cut the power to them. This is especially useful if you only use them in the evening or on certain days as then they aren’t drawing power 24/7.

Phones and Tablets - Yes, these are battery operated, but the problem lies in the charger. When your charger is plugged into the wall (whether or not the phone is connected) it is drawing electricity. Just unplug your chargers when done charging your devices.

Ovens - This one uses a lot of electricity, so the solution is to use it as little as possible. If you can use a microwave or a toaster oven, then opt for those as they won’t cost you nearly as much electricity.

Save Energy On Water Heating

Keeping a supply of hot water actually uses quite a bit of electricity. It usually makes up about 22% of your overall electric bill, to put things into perspective. So as you can imagine it’s no small source of usage. Fortunately, there are quite a few ways to cut back on the amount of electricity that gets used on water heating. While some may require some habit changes, others are pretty smart. So if you're looking for how to reduce your electric bill, this is a good place to start.

Let’s get the habit changes out of the way first. We’ll start with baths. It’s well known that taking a bath uses a lot more hot water than a shower does. While they are quite relaxing, think about how much water is getting used up. Aside from using less electricity (in terms of water heating) showers also save water and are more hygienic. So maybe a quick shower would be better.

Next, stop washing clothes and dishes with hot water. With the effectiveness of modern detergents and soaps, there really isn’t any need anymore. Your dishes will come out just as shiny and clothes just as clean if you only use cold water. Actually, certain stains will set in faster with hot water than cold, so there’s another reason to change.

Speaking of washing dishes, try doing one big load instead of several small ones. Not only will this use less water in general, but will also save on straight electricity.

Finally, make absolutely sure that you don’t have any hot water leaks. This can be very costly as your water heater is constantly having to reheat water as it gets added. If you find a leak (even just a slight drip) get it fixed immediately.

Saving Energy On Lighting

When one thinks of electricity, usually a light bulb comes to mind. The humble light bulb has become the nearly universal symbol for electricity use, and with good cause as it was the first practical home usage for the stuff. However, the light bulb as we remember it (of the incandescent variety) is quite inefficient these days, and is due for an upgrade.

Lighting, while not the biggest use of electricity, is something that we can easily manage so as to save electricity. Here’s a few different ways that you can save energy on lighting:

  1. Install LED light bulbs as they use much less electricity than any other variety. As a matter of fact, incandescent light bulbs are being phased out and soon you won’t be able to buy them anymore. LED bulbs are a little more expensive, but they last much longer too, so it’s really worth it in the end. Also morth mentioning, that along with LED bulbs, ther are other energy saving gadgets that are worth checking out.

  2. Turn off unused lights. Leaving lights on is a big waste of electricity. Which is a shame as it’s really easy to correct. Just make a mental note to turn them off and soon it will be a force of habit.

  3. Install dimmer switches for your most often used lights. This way you only use as much electricity as you need. You can also set whatever mood you desire. Just remember that not all LED bulbs are dimmable, so get the kind that is.

  4. Using natural light during the day is another easy way to save on lighting. It’s free and is available all day long on sunny days. Do your reading by sunlight and save.

See? Saving money and electricity on lighting is actually pretty easy. All of the above tips can be put into action over the course of a single weekend. None of the “installation” of anything is particularly difficult and can all be done by one’s self.

Other Ways To Save Energy

One of the biggest ways to help the environment is through the conservation of energy. When you think about saving energy, you probably think about conserving electricity. While this is a major way to contribute (and can help you save on electric bills), did you know that there are other ways to help conserve energy?

Let’s take recycling as an example. It takes less energy to process used plastics than it does to make new ones. This process not only wastes energy, but it also uses up natural resources. This is a real shame especially when you consider just how much plastic is thrown away each year, never to be recycled. Each time you recycle, you’re helping to not only keep landfills from overflowing, but you’re protecting natural resources as well as saving energy.

Recycling isn’t the only way, so is saving fuel. It’s also not all that hard to do. A big solution would be to get a very fuel efficient, or hybrid, or all-electric car. This is really where the motor industry is headed and it’s high time to get behind this one. Electricity has the potential of being produced in an environmentally way, while gasoline doesn’t. Not to mention that the use of it is also harmful for the environment. If buying a new car isn’t an option for you, you can try any other solution: carpooling, public transportation, walking every now and then, etc.

So you see, when it comes to energy conservation, there is actually plenty that the average person can do. Between saving electricity at home, conserving fuel (or not using any altogether) and recycling, we can really help make a difference that will lead to a clean and green future for generations to come. So let’s really decide to make it happen and implement these various changes and methods into our daily lives for blood!

A Few Habit Changes For Better Energy Efficiency

Sometimes, when you want to save energy around the house, you’ll need to make a few habit changes. Excessive use of electricity isn’t always just because of inefficient appliances. Sometimes, it’s all about the way YOU use it that will lead to ways to save on electric bill costs.

Now this doesn’t mean that you’re going to have to change everything about the way you use energy. Rather, a few simple alterations will go a very long way indeed. So let’s take a look at a few simple changes you can make to help conserve energy.

  1. Use more fans. Yes, summer is almost upon us, and with it comes unbearable heat. Usually this means that people will run their a/c all day long, which gets really costly. A solution is to raise the temperature by about 2° on your thermostat, and use fans to supplement this. The moving air will make you more comfortable despite the increased temperature. 2° may not sound like a lot, but it saves quite a bit of energy.

  2. Turning appliances off is another important one. Many people don’t just leave lights on, but other appliances as well. With many devices these days being smart devices, one can set them to turn off automatically, but still, getting into the habit of doing this yourself is preferred.

  3. This last one is key, and that is not to use more appliances than you need to at once. Some people will be watching TV, while using a computer, and possibly even doing something else all at once. Your attention is only every really on one of those things at any one given time, so just pick one rather than waste all of that electricity.

These simple changes can really go a long way towards helping you to reduce your energy usage. Once you get used to applying them, it gets pretty easy to keep it up.

Do Power Savers Really Save Energy?

If you’re someone who has been interested in saving energy, and has done any amount of research into different ways to do it, then you have probably come across a device known as a “power saver”. Actually, it comes under a variety of other names (depending on who’s selling it) but they are all essentially the same: a grey box with wires coming out of it that supposedly can save electric energy in your home.

They are made by different companies (although all the same device, really) and sell at different prices, yet one thing holds true for all of them: the doubt as to whether they work or not.

Well, after some experimentation, we can say that yes, they do work. But that is the short answer. The long answer is: usually, but it depends on the circumstances. Let’s get into detail.

You see, what the device does is corrects something known as “power factor”. This is a situation wherein more electricity is being drawn by an appliance than is actually needed. This is not something that every appliance causes. But, it is caused by air conditioners (which are found in virtually every home). And as a/c units make up 50% or more of the average electricity bill, then this is a good area to improve.

The problem comes from people who install the unit either:

  1. incorrectly, or

  2. didn’t need on in the first place.

Incorrect installation will of course lead to poor results. It really should be installed by a professional. The people who don’t need the unit are those who live in areas where they don’t use much a/c, or who have very small a/c units (like people who live in apartments. There are, of course, exceptions to these rules, but if there is any question as to whether or not the unit will reduce your bill, you should ask the company selling it. Though the general rule is that if you live in a medium sized home and use your a/c for more than 8 hours a day, then you should get some benefit from the device.

Doing Your Part For Mother Earth

We’re pretty big here on helping the environment. And we believe that everyone should do all that they can to help preserve it. While we do focus a lot on ways to conserve electricity (which is really important) there are other ways to help out.

So today, let’s look at some of the other ways that you can start helping your environment.

First, let’s talk about recycling. Most people do try to recycle, and that’s good and fine, but there is another aspect of it, and that is buying products that are themselves made from recycled materials. When you buy these types of products, you are making the cycle complete, going full circle so to speak.

Next, let’s talk about waste. Many of us throw thing away without a second thought. But realize that all of the trash that we produce has to go somewhere, and last time I checked, we aren’t blasting it all out into space. So it gets dumped somewhere here on Earth. So what’s the solution? Aside from recycling as mentioned above, try repurposing old items. Things like clothes, electronics and even furniture can be repurposed. If you look online for DIY ideas, you’ll find plenty of cool projects that can be done using your old stuff.

Next, let’s talk about actively improving the environment. When was the last time you went outside and planted something? I’m not talking about going out to the woods to go planting trees (though if that’s your type of thing, then go for it). I’m talking about in your own back or front yard. Some types of plants can be gotten cheaply and will not only make your home prettier, but will also improve the local air quality.

So get out there and continue doing your share. We all live on this big old rock and have to take equal responsibility to ensure that it stays healthy and well. It’s the only home we have.

Home Energy Saving: Part 2

Welcome to our next article in the series. I know that we missed last week, but things are back on track now and the series will continue as planned.

Ok, so we have a whole new set of energy savings solutions for you. Many of them are free to apply while others will require some additional equipment. But don’t worry because they can easily pay for themselves after some time of use.

So let’s get right into it then.

While we have covered unplugging appliances to get rid of “phantom charge” many people don’t realize how many things this applies to. Any appliance that still has a light or other display constantly on (like a microwave that displays the time) will waste energy. Same goes for charging cables for phones and other devices. Unplug them!

Another point on energy wasting is that many appliances are just naturally inefficient. Take a/c units for example. They use something called an induction motor inside. This type of motor generally draws more electricity than it really needs. This wastes a lot of electricity. Installing an electric saver in your home is a good way (pretty much the only way) of putting this to an end. This will not only save on heating and cooling, but on any other appliance that is guilty of this waste as well (like pool pumps and some refrigerators).

You can also save money on heating and cooling by using the sun to your advantage. Open up blinds in the winter to let warming sunlight in, and do the opposite in the summer. You’d be surprised what a difference direct sunlight can make.

That’s all for this week. Next week we’ll publish even more energy savings solutions that anyone can save energy at home. So stay tuned to not only do yourself a favor in terms of lower energy bills, but also to help the environment through energy conservation.

Energy-Minded Shopping

Anytime that we are purchasing a new appliance for the home is an opportunity to start saving more energy. After all, with a newer appliances usually comes better technology that can get the job done better with less energy spent. But before you decide that all that you need to do is look for the Energy Star label and buy one with it, you’re missing a bit of information that will help you to save on electric bill costs.

Yes it’s true that appliances that are Energy Star certified will use less electricity than their uncertified equivalents. They typically use about 10% less electricity, though this can vary depending on the type of appliance. They also use less water in the case of washing machines. So getting Energy Star is a must, for sure. But there’s another point to take into consideration which is completely different.

And that is the size of the appliance itself. Let it be clear that in the world of energy saving, size does indeed matter. But unlike in most other areas, smaller is definitely better here. Let’s say you are getting a new washer and dryer. Sure, you could get an Energy Star one and be done with it, but getting the smallest one that will support your needs will also help to save on electric bill costs. This idea can be applied to most any type of appliance; refrigerators, stoves, microwaves, etc.

This principle will also help you to save money. Not just in the long run on electricity (which it will do), but also at the time of purchase, as the smaller appliance will most likely cost less too. So you’re getting two points of savings with the one purchase, all while doing your part to help conserve energy. Truly a win-win situation. You’ll get a big thanks from Mother Nature, and from your wallet as well.

Home Energy Saving: Part 1

We are debuting a new series of articles that will be dealing with teaching people how to conserve energy and save money in their home. This will benefit the environment as less energy will be used/wasted and also the individual doing it as their electricity bill will be lower.

For this first article, we’re going to take a look at reducing the electricity spent on general appliances throughout the home.

So let’s get started!

First off, you may not know this but many appliances and electronic devices still consume some electricity even when they are turned off. This is called “phantom charge” and can be easily stopped by unplugging appliances and devices you aren’t using. Now this can get cumbersome, so you can get a smart power strip instead and it will do the exact same thing automatically.

Next, let’s look at washing clothes. 2 tips here. The first is to was as few loads per week as you can. Doing only a couple of large loads uses less energy than many small ones. The second tip is to wash with cold water. This uses less electricity as more water will not have to be heated up after.

Moving on to the fridge, make sure that you set the temperature to a setting that isn’t overly cold (this goes for the freezer too). Your fridge needs to be 40° to keep food fresh, and freezer below 32°. Also, keeping bottles of water in the freezer can help reduce electricity as well as they help keep your freezer cold.

Finally, always remember to turn appliances off when you’re not using them. TV sets left on, radios left playing, all these “little things” add up to lots of energy wasted and higher electricity bills.

 

Hope you've learned a little about how to conserve energy.

Stay tuned next week for another article in this series.

How Bad Is Coal Burning?

One of the questions I frequently get asked is just how bad is burning coal for the environment. Surely it can’t be all bad as the coal occurred naturally. While it’s true that coal naturally occurs, burning it has increased the amount of CO2 being pumped into the environment annually.

This brings up another question of how much are we really upsetting the “natural balance”. After all, there’s tons of CO2 put into the air all the time by living beings simply breathing. Not to mention volcanic eruptions and the like. Are we really adding all that much to cause concern?

The answer is yes. While natural sources are pumping loads of CO2 into the atmosphere (about 200 million tons per year from just volcanoes), we are adding far more than that. Coal burning in just the US alone was over 1.5 BILLION tons in just one year. So as you can see, while the environment can naturally deal with some CO2, it wasn’t designed to handle the amounts that we are adding.

So what’s the point? Well, we really need to start getting behind a clean energy initiative. THis means writing letters to congressmen and representatives, demanding change in the way we produce energy. It also means that we need to be doing our part to reduce the electricity consumption in our own homes. This can be done rather easily through various habit changes (like remembering to turn things off), replacing appliances (getting Energy Star certified ones) and employing the use of energy saving products (like the electric saver devices found here: http://electricsaver1200.com/lower-electricity).

Despite what some will tell you, it’s not too late to change the fate of our environment. If we start now and really make a commitment, we can better the start of our atmosphere for the good of all life on this planet.

Saving Energy On The Road

When we think of conserving energy, we often think of getting a lower electric bill in the home. And yes, while this is necessary and beneficial, it’s not the only way, as we have another area where we consume loads of energy: the car.

Reducing the fuel consumed is a great way that we can assist on global energy conservation as well as reducing our own personal carbon emissions. Now, while conserving energy in the house can be easily done with a product like an electric saver, it’s not as clear cut in the car.

So to help you out, here’s some tips to saving energy in the car.

  1. Ensure you don’t have any excess junk in the car. This adds weight and will ultimately reduce your MPG causing you to waste energy. Also, if you drive in the city, you can ditch the spare tire and use a can of fix-a-flat instead to further reduce weight. Run lighter to run longer.

  2. Keep your car’s filters clean and get regular maintenance. This will also improve your MPG as well as keep your car running smoothly for longer.

  3. Plan trips to the store and other errands in advance so you can do multiple things in one trip. This is pretty basic but you can save quite a bit of gas this way.

  4. Walk on occasion. If you live near your local supermarket or drugstore and you need a couple of items, save the car and take a short walk.

  5. Carpooling is another great idea. Save money on gas and get to better know your coworkers.

  6. Finally, there’s public transportation. Getting a bus pass can be cheaper than buying gasoline also.

As with all of these tips, you’ll not only be doing your part to help reduce CO2 emissions and conserving energy, you’ll also be saving yourself money on gasoline.

Environmentally Friendly Home Activities

There’s plenty of ways that you and your family can help the environment but let’s face it, some of them aren’t any fun at all and you may find yourself wondering how can we conserve energy without having a horrible time of it? Actually, there are some really neat and creative ways that you can get the whole family involved in that will not only be entertaining, but will also promote good, clean habits.

The first is recycling. No, not the usual sorting and separating, but more on personal recycling by using various objects over again. Doing a quick search for some recycling ideas and you’ll see loads of projects that the whole family can participate in. From decor ideas to really useful projects, there’s something that everyone will enjoy.

The next is saving energy. A really fun way to do this is by planting trees and shrubs around the home. This will provide shade from the sun and actually lower your a/c costs. Let family members pick what kinds of plants they would like and then spend a day outside doing some planting. You can also save energy by having everyone engage in an outdoor activity at least once a week. Save the electricity spent on the TV, internet and others and get active and outside. Also good for your health.

Finally, there’s another way to save energy and that is through solar panels. No, not the big kind that go on your roof, but a smaller version that comes in a kit. Everyone can set one up near their bedroom window to give themselves a clean and green way for charging their phones or other devices.

Got any more ideas for fun ways to help the environment? Leave your suggestions in the comments section and let us know more ways we can all learn how we can conserve energy.

Why So Many Still Deny Climate Change

With all of the overwhelming evidence, studies, professionals and international recognition of climate change, it can be hard to believe there are those out there who will tell you that it’s all made up. They’ll tell you that the Earth’s climate is not majorly influenced by mankind. They’ll look at the statistical increase of melting ice in both the north and south poles and simply shrug it off. They may even tell you that as a species, we are incapable of making a change in Earth’s weather and so shouldn’t even try to do anything about it. Why? Well, it’s a very simple reason: vested interest.

If you look at the major players who are campaigning against climate change, you’ll find somewhere that they have ties to or personal interest in markets that benefit from fossil fuel or other non-sustainable sources of energy. It all boils down to money. If climate was completely recognised as the threat that it is, then they would lose money as other, more sustainable and eco-friendly forms of energy would become the majority, leaving fossil fuel where it belongs: in the ground.

So what can you do to help? Signing various petitions in support of stopping climate change can be of great help (http://www.globalwarmingpetitions.com/). There is also the matter of continuing to find out how to conserve energy and apply ways to reduce your own personal energy consumption as this will help to lower overall demand. There’s plenty of ways that this can be done and some of them are even free to implement. Finally, one can always call or write their senator and congressman to make their voice heard on the subject of climate change. If enough people do, they will be forced to address the matter for fear of losing voter support. You can make a difference, you only have to just do something.

Reducing Personal Carbon Emissions

OK, it’s well established that CO2 emissions are harming the atmosphere.And with over 6 billion tons being added to the atmosphere each year (yes, by mankind), you can see that this is something which needs immediate attention. And while it’s going to take some time before big companies really do something to handle the problem, that’s not stopping individuals from doing their part to help by reducing their own personal emissions.

There’s 2 general areas where this can be bettered: in the car and in the home. The car is an obvious one as you can literally see the CO2 being thrown out of the muffler. In the home, it’s all about reducing your electrical usage by finding ways to conserve electricity.

But what does the amount of electricity you use have to do with CO2 emissions? Well, if less electricity is used, less demand for it’s generation results. This means that less coal and other fossil fuels will be burned to generate electricity thus lowering the quantity of CO2 being released. There’s lots of ways to reduce your electrical usage. One can upgrade their appliances to energy efficient models. Power saving devices can be installed. Better usage habits can be adopted. There’s plenty of ways to conserve electricity in the home.

As far as in the car goes, you also have many options. You can carpool (which also saves money), use public transportation, get a hybrid or electric car, or maybe if the distance isn’t too great, just walk (haven’t we all been meaning on doing a bit more exercise?).

If everyone does their part, no matter how small it may seem, big changes can result. Don’t sit idly by and just watch as our planet suffers. it will only come back to haunt us. Start doing your part today and help to create a brighter and cleaner future for all.

Saving Energy In Your Business As A Means Of Reducing Expense

Running a successful business could be boiled down to the most basic idea of keeping expenses less than income. Sure, there are a lot of other elements to it, but this fundamental principle must be achieved if the business is to survive. So a priority of any business owner can and should be finding ways to keep costs down without sacrificing the quality of the product.

With factors like inflation not to mention the general state of the economy, this can be a tricky task. After all, there are some things that any business just couldn’t function without. But there are places where money can be saved without having to “cut corners”, and one of them is by lowering your electric bills.

Most businesses (and homes too for that matter) are paying much more for electricity than they should be. This isn’t due to being overcharged by the power company, but rather than many appliances draw more electricity than they in fact need to run, and this additional, or “excess” electricity simply converts into heat and is lost (but still paid for as it traveled through your power meter). The goal then would be to eliminate this waste through an improvement of efficiency.

The best and easiest way to do this would be through the use of an electric saver device. This machine will literally collect the otherwise wasted electricity and then send it back out to power your appliances. This way, a higher percentage of the electricity consumed is put to use, thus less electricity overall will be drawn from the power company. Thus, your electric bills are lower.

Depending on the type of business you run, this could mean thousands of dollars per year. For example, someone who needs to run a lot of air conditioning units or refrigerators would benefit greatly from this type of device as A/C units and refrigerators waste a lot of energy.

Hydrogen from sunlight and water

Posted By : Kamlesh Jolapara

hydro solar
We heard about hydrogen as a fuel could be easily generated from the solar energy. Sounds amazing! However, there was no convenient or easy solar hydrogen system available in the world from which we can harvest hydrogen from the solar energy directly. The Ideal solar hydrogen system should be such that it creates hydrogen easily from the abundant available material with minimum cost and sufficiently reliable to power cars and homes in future.
 
New invention
I think our search for such kind of system is over; the journal ‘Science’ has published a new way to produce hydrogen fuel from sunlight and water, the method was discovered in Michael Gratzel’s laboratory at Ecole Polytechique Federale Lausanne in Switzerland. Researchers have created a way to use abundantly materials to build a device that uses solar energy and water to make hydrogen.  By combining a pair of solar cells made with a mineral called perovskite and low cost electrodes, scientists have obtained 12.3 per cent conversion efficiency from solar energy to hydrogen, a record using earth-abundant materials as opposed to rare materials. The race is on to optimize solar energy’s performance. More efficient silicon photo-voltaic panels, dye-sensitized solar cells, concentrated cells and thermodynamic solar panel all pursue the same goal: to produce a maximum amount of electrons from sunlight.
 
How hydrogen is made
At the Laboratory of Photonics and Interfaces at EPFL, led by Michael Gratzel, where scientists recently invented dye solar cells that mimic photosynthesis in plants, they have also developed methods for generating fuels through solar water splitting. To do this, they either use photo electrochemical cells that directly split water into hydrogen and oxygen when exposed to sunlight, or they combine electricity-generating cells with and electrolyser that separates the water molecules. By using the latter technique, Gratzel’s student Jingshan Luo and his colleagues were able to convert water into hydrogen using energy diffused by the sun on perovskite absorbers – a compound that can be obtained in the laboratory from common materials, such as those used in conventional car batteries, eliminating the need for rare-earth metals in the production of usable hydrogen fuel.
 
Store hydrogen in a bottle
This high efficiency provides stiff competition for other tech used to convert solar energy and has several advantages over other methods. “Both the perovskite used in the cells and the nickel and iron catalysts making up the electrodes require resources that are abundant on Earth and that are also cheap,” explained Jingshan Luo. “However, our electrodes work just as well as the expensive platinum based models customarily used.” On the other hand, the conversion of solar energy into hydrogen makes its storage possible, which addresses one of the biggest disadvantages faced by renewable electricity – the requirement to use it at the time it is produced. Once you have hydrogen, you store it in a bottle and you can do with it whatever you want to, whenever you want it. Such a gas can be burned – in a boiler or engine – releasing only water vapour. It can also pass into a fuel cell to generate electricity on demand.
 
Powerful cells for future
These high efficiency values are based on a characteristic of perovskite cells: their ability to generate an open circuit voltage greater than 1V (silicon cells stop at 0.7V). A voltage of 1.7V or more is required for water electrolysis to occur and to obtain exploitable gases. To get these numbers, three or more silicon cells are needed, whereas just two perovskite cells are enough. As a result, there is more efficiency with respect to the surface of the light absorbers required. This new invention requires more focus on further development to get it more suitable for commercial applications.

Hydrogen from sunlight and water

 
We heard about hydrogen as a fuel could be easily generated from the solar energy. Sounds amazing! However, there was no convenient or easy solar hydrogen system available in the world from which we can harvest hydrogen from the solar energy directly. The Ideal solar hydrogen system should be such that it creates hydrogen easily from the abundant available material with minimum cost and sufficiently reliable to power cars and homes in future.
New invention
I think our search for such kind of system is over; the journal ‘Science’ has published a new way to produce hydrogen fuel from sunlight and water, the method was discovered in Michael Gratzel’s laboratory at Ecole Polytechique Federale Lausanne in Switzerland. Researchers have created a way to use abundantly materials to build a device that uses solar energy and water to make hydrogen.  By combining a pair of solar cells made with a mineral called perovskite and low cost electrodes, scientists have obtained 12.3 per cent conversion efficiency from solar energy to hydrogen, a record using earth-abundant materials as opposed to rare materials. The race is on to optimize solar energy’s performance. More efficient silicon photo-voltaic panels, dye-sensitized solar cells, concentrated cells and thermodynamic solar panel all pursue the same goal: to produce a maximum amount of electrons from sunlight.
How hydrogen is made
At the Laboratory of Photonics and Interfaces at EPFL, led by Michael Gratzel, where scientists recently invented dye solar cells that mimic photosynthesis in plants, they have also developed methods for generating fuels through solar water splitting. To do this, they either use photo electrochemical cells that directly split water into hydrogen and oxygen when exposed to sunlight, or they combine electricity-generating cells with and electrolyser that separates the water molecules. By using the latter technique, Gratzel’s student Jingshan Luo and his colleagues were able to convert water into hydrogen using energy diffused by the sun on perovskite absorbers – a compound that can be obtained in the laboratory from common materials, such as those used in conventional car batteries, eliminating the need for rare-earth metals in the production of usable hydrogen fuel.

U.S. Used More Energy in 2013 Than the Year Before, But Efficiency Is Up Too

Posted by Pete Danko

more energy usedEnergy use increased in the United States in 2013 as a fourth consecutive year of economic growth exerted its influence, but the longer-term trend shows the country operating with greater efficiency while also revealing the small but growing role of renewable sources like solar and wind.

The font for these insights is the Lawrence Livermore National Laboratory and its “energy flow chart,” an annual tally of U.S. energy consumption that colorfully connects energy sources with their end uses in the residential, commercial, industrial, and transportation sectors. There’s a hefty “rejected energy” component, as well, for energy that is consumed but not put to use, like waste heat. The recently released 2013 chart showed energy use at 97.4 quadrillion British thermal units, an increase of 2.3 quads over 2012.

But don’t worry – this isn’t evidence that all those energy efficient light bulbs and LEED-certified buildings are for naught. Energy use was still down significantly from the all-time U.S. record of 101.5 quads established in 2007, just before the economy crashed – even though the economy is now about 6 percent larger than it was in 2007, as measured by real gross domestic product.

“We’re seeing two trends fighting each other,” said A.J. Simon, group leader for energy at the California lab. “Energy use is notching its way back up as the economy grows, but generally people are doing more to be efficient in how they use energy.”

The transportation sector is a good example of this: Compared to 2007, people are using public transportation more and driving less, and when they do drive, they’re doing so in cars and trucks that, on average, deliver improved fuel efficiency.

As a result, although petroleum use inched up a bit last year, its use in the transportation sector was down from 27.71 quads in 2007 to 24.7 in 2013 (biofuels have picked up some of the slack, doubling their contribution in the same period, to 1.24 quads for transportation).

Simon noted that a complex set of factors determine how much and what mix of energy is used in a year, with weather being an especially important wild card. For instance, in 2013, winter cold snaps in February and March, and then again in December, drove up the use of natural gas for home heating. That additional demand for natural gas pushed prices higher, which led to more coal being used for electricity generation in 2013 – and that, in turn, largely explained the uptick in carbon dioxide emissions that the lab noted in a companion carbon flow chart.

Still, it was just a small bump up for coal, from 17.6 to 18 quads. Peering back a decade, coal was the source of 22.9 quads of energy use in 2003. Natural gas has surged since then, of course, although strictly on a percentage basis wind power has it beat. The thickness of the lines on the energy flow chart are not precisely scaled to the amount of energy drawn from a particular source, but attempt to give a reasonable picture. Simon remembers a time not long ago when the wind line was drawn as narrowly as possible, so minuscule was its contribution.

“It used to be one pixel,” he said, “but it’s not one pixel anymore,” with wind’s contribution rising from 0.11 quads in 2003 to 1.6 in 2013, a 1,355 percent increase.

Solar’s yellow line on the energy flow chart is still barely visible, but at the rate installations are growing, it too might take on new dimensions before long. In 2003, solar was at 0.06 quads; in 2013, it had grown to more than five times that, at 0.32, boosted by a 36 percent surge from 2012 to 2013.

Another Reason to Promote Clean Energy in Developing Countries

by Antonio Pasolini

clean energyBillions of people live without access to modern electricity services and clean energy could lift them out of the economic exclusion zone, improve their education and make their lives generally better. It can also save some lives, literally.

Of all the reasons to advocate clean energy, this may be the most surprising one. The Legal Human Rights Centre (LHRC) recently reported that over 3,000 people were lynched in Tanzania by neighbors who thought they were witches.

And what does that have to do with clean energy, you may be asking yourself? Well, it so happens that many of these victims are old women who develop red eyes, considered to be a sign of witchcraft, for burning cow dung for fuel as a substitute for firewood.

It is hard to believe that this sort of thing happens at this day and age. Apparently the women often are killed shortly after the death of a relative, which they are blamed for.

 

Albinos are often murdered as people believe that making potions from their body parts can attract wealth. This group is also a victim of rape as some people believe that intercourse with them can cure them of AIDS. They believe albinos are cursed and simply disappear instead of dying.

This story highlights how education and access to modern, clean technology ramifies into areas that we would never imagine at first. Portable solar-powered solutions could help people like those women in Tanzania to replace dirty fuel with clean energy. Luckily some innovators have been working to develop portable solar solutions for people in African countries, such as Eight19 and its pay-as-you-go solution . Let’s hope that the more people in Africa get access to solar, the fewer casualties there will be due to a case of red eyes.
