The Claymore MAC Global Solar Energy Index ETF, TAN, had fallen 78% over the past years, but they’re back. Most listed solar companies had fallen from 50% to 87% over that period, but a bright spark however, was the passed economic stimulus bill which started boosting demand once again. With the extension of the Federal 30% tax credit and the removal of the $2000 cap, home owners will see the price of solar PV get much more affordable.
And, for commercial developers of solar facilities the new bill has provisions that would allow them to take the 30% tax credit as a grant instead. Some of the companies best positioned to ride out the challenges of this year are the big market leading companies with adequate cash in hand. US manufacturer First Solar is one of these companies.
If you would like to be a good example and role model for kids on sustainability, be it at home, in the classroom, or for your nieces and nephews, you can start by teaching them how to respect nature, to be mindful of all the waste they’re creating, and so on. more.
In short, there are so many ways to teach them all about our planet, how to treat it respectfully, and how to best deal with sustainability. And at the same time they can have fun learning it and doing it.
Take a look at a few quick pointers to do so. Here are five tips to get started with teaching children about sustainability, and this is all geared towards younger audiences:
1. Lead by giving the good example 2. Make learning about sustainability fun 3. Get all kids really involved 4. Read about sustainability to them 5. Volunteer in a sustainability program together with the kids
Wave energy is produced when electricity generators are placed on the surface of the ocean. The energy provided is most often used in desalination plants, power plants, and water pumps. Energy output is determined by wave height, wave speed, wavelength, and water density.
To date, there are only a handful of experimental wave generator plants in operation around the world. The articles on this page explore the world of wave energy and its possible applications.
Much of the the technology and ingenuity required to seriously reduce the threat of global warming already exists, and this includes solutions that are going to stimulate the American economy because they will be creating jobs, saving consumers and government money, and will be helpful to protect our national security. The key is sustainable or renewable energy.
By committing to and investing in renewable energy and, just as important, energy efficiency of appliances we use and the cars we drive, we can take significant steps towards minimizing our dependency on fossil fuels. We know that our consumption of oil is contributing to the threat of global warming.
We should, and are capable to, use energy much more efficiently and benefit from much more renewable energy sources, including wind, solar, geothermal, and bio-energy. We must rapidly work towards a significant reduction of emissions of heat-trapping gasses, like carbon dioxide (CO2) methane, and nitrate oxide. We need well-educated executive managers who are ready to go all the way.
Going Green isn’t only about changing a light bulb or buying expensive products. Going Green is a way of life and has to do with our holistic approach to life. Our careful choices immediately have an impact on your health and, essentially, the health of our planet.
But don’t think that little things don’t matter! It just takes a bit of effort to go a long distance. Here you can find some tips to make your life a little greener, too.
Are you really serious about Green Living and Going Green? Then, consider taking some big steps, what about changing your career and contributing to the development of clean energy technologies? If you don’t have a high school diploma, you can get your GED diploma (even if you just study online) and apply for a green career, it might be something for you! Check out these MyCareerTools free practice tests for the GED exam.
Clean energy careers are hot, they are favorite choices of career for many students who are attracted by many well-paid and in-demand jobs. Clean energy job would make you feel good and will benefit our mother-earth.
We all are concerned about climate change and the effects we already experience. But what if Global Warming is a natural phenomenon? Many people claim that on our planet, warmer and cooler periods have occurred for as far back as we are able to determine.
Periods of Global Warming have occurred some 100,000, 200,000 and 300,000 years ago, and scientific data has been obtained from proxy sources including sediment layers and rocks, ice cores, tree rings, and coral reefs. Compiling all these data allows us to determine temperatures millions of years ago.
What obstacles keep us from switching to renewable energy?
Stranded Cost:Across the US, we already have been paying some one trillion dollars for the infrastructure for fossil fuels. There are people who say that, if we were to switch entirely to renewable fuels, this huge investment could be ‘stranded’, unless we would find ways to include it. This is why there is opposition against switching to renewable fuels as this would create a huge economic disincentive. There are others who argue that abandoning this existing infrastructure gradually would be a lot cheaper than giving it up immediately.
Upfront Cost: There are renewable sources (wind power, hydropower, and geothermal power) that are currently (practically) competitive with fossil fuels, but solar energy continues to be pretty much more costly than coal-based electricity. The budgetary mechanisms to that allow renewable fuel systems to be paying for themselves in a natural way simply do not exist yet.
When you hear the words wind turbine, you probably think of gigantic structures that generate electricity for big companies. Wind turbines actually come in a variety of different sizes and types. You could use a smaller version of the huge ones in order to generate electricity for your own home or business. There are tons of different ones to choose from and depending on how much electricity you need, you may be able to find the right one for you for less than you think.
So how does a wind turbine work? They generate electricity from the wind. Wind turbines most often come in the form of a windmill and are able to seemingly make electricity from thin air. In fact, they do! With a geared power train, wind turbines are able to generate lots of electricity. Some people favor these machines more than solar panels. They are cost effective and able to pay for themselves within a few short years.
Basically, the solar panel is a device used to generate energy. Energy that doesn’t require raw materials and, even better, it’s free and renewable.
Going into further details, solar panels are means of capturing and using solar energy. There are two big types of solar panels:
Solar panels used for heating
Solar panels which use photovoltaic (PV) cells for producing electricity
Solar Panels Used For Heating
These types of solar panels are used for warming the water or the house. Their working process, very much simplified, is the following: the panels capture solar heat and transfer it with the help of tubes to a water flow.
Imagine being able to completely offset the cost of your electricity bills. Never again do you have to pay for electric energy. Instead, people are now able to generate their own electricity entirely through the use of solar energy systems. A solar energy system would make a great addition to your household. The ability to produce electricity for free is certainly enticing isn’t it? Thousands of people before you have made the jump into using solar energy for all of their electricity needs. Your home could benefit from a solar energy system and it would save you thousands every year.
In order to get the most rays from the sun, most solar energy systems will have panels that go directly onto your roof. Roof set ups are the most effective way to use a solar panel set up because it has the most exposure to the sun. People who own homes aren’t the only ones who are taking advantage of solar energy systems. Big companies are also using them, connecting an immense number of solar panels to the roofs of their company buildings.
