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.

Going Green isn’t only about changing a lightbulb 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 a career and contributing to the development of the clean energy technologies? Take a career quiz and see if a green career is something for you.
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.
The most debated topic on earth is the issue of climate change. This a universally accepted statement. The system of the seasons is changing, and climatic conditions have become unpredictable. Nonseasonal rains are being experienced, the earth is getting warmer, glaciers are melting down, and the sea levels are rising. Fertile lands are becoming infertile and diseases are spreading, some fear that life as we know it will be ending soon, just imagine what actions must be taken now to save our planet for next generations.
Who do you think is the culprit of these current situations? Well, in fact it is us, as we are all humans, aren’t we? It is our own activities that have resulted in the current situation.
So the following questions might come to everybody’s mind:
Harnessing the sun’s energy makes sense because it is clean, green, and saves money in the long run. But the reality is that the cost involved with installing panels and collectors is still out of reach for the vast majority of homeowners. Fortunately there are some cheap and easy ways to make the sun work for you.
Passive solar means simply using or blocking the sun’s rays to heat or cool your home. This means that using your window coverings wisely can save you a ton on your power bills. Simply closing or angling your blinds to keep direct sunlight out can drop the interior temperature by 10 degrees. Try closing the window coverings on the south side of your house when you leave for the day during the summer months. Without the sun’s hot light shining in the windows, your air conditioner won’t have to work as hard. And in the winter of course doing the opposite can help heat your house. There tons of great looking blinds, awnings, and window films to help you harness or block the sun’s powerful rays.
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.
With high gas prices and global warming on many people’s minds, consumers are looking for ways they can participate in energy conservation and reduce their carbon footprint. And while you may not be ready to buy a Toyota Prius or install solar panels in your home, there a number of everyday things you can do to adopt a green living lifestyle and contribute to energy conservation.
Learn how to be eco-friendly and protect the environment without breaking the bank with these 10 Energy Saving Tips.
Think green and plant trees [link to: NW Am. Forests page]. If you’re wondering how to be eco-friendly, one of the best – and greenest – ways is to plant trees around your yard or office. Trees are inexpensive, require little maintenance and act as filters by constantly removing air pollution from the atmosphere.
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.
There is no dearth of job opportunities in the renewable energy sector. There is also great variety when it comes to renewable energy careers. This may often make it difficult for prospective employees to choose their professional niche. This also makes it possible for people from various backgrounds to make their foray into the field. Interested candidates may even undergo professional training to become a part of the industry.
Like any other sector, renewable energy recruitment also has much room for people from diverse backgrounds. These include marketing, communications and other fields of business support. There are diverse aspects of business and various other tasks associated with it. These include accounting, corporate planning, information technology, business law, finance and human resources. Apart from these, career opportunities abound in diverse fields of renewable technology sector. Opportunities in the sector are available in the fields of wind power, photovoltaics, solar power, hydropower, geothermal energy and bio-energy.
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.
