The transition to renewable energy is set to deliver an economic pay off as well in the years to come. Various studies show that a shift to alternative energy sources will raise the GNP in the coming decade and create new jobs, as Prof. Eicke Weber, spokesperson for the Fraunhofer Energy Alliance, points out More »
Over the last few years, wind and solar proponents have been battling it out to take the top spot in the clean energy discussion. However, when it comes down making a purchase on a smaller scale, solar is king. Solar panels are smaller, more discreet and, most importantly, they’re a proven commodity.
Still, that doesn’t mean they’re always the best option. According to Earth2Tech, the “small” wind turbine market is expected to double by 2013. By the way, I put “small” in quotes because were talking small in terms of output (100KW or less), not size. Look at the 100KW turbine in the picture and you’ll see what I’m talking about. More »

A report recently published in an online journal called Advanced Materials points out that a process has been developed by the researchers at the Iowa State University and the Ames Laboratory that can produce thin and constant light absorbing layers on textured substrates. This increases light absorption by polymer solar cells, thereby increasing their efficiency and enabling its best use.
Why has polymer solar cell technology failed so far?
Mr Chaudhary says that since it is already being used in silicon-based solar cells, the use of textured substrate to increase the working capacity of solar cells is More »
BROOKLYN, NY–(Marketwire – March 15, 2011) – Brooklyn Bridge Park and Beautiful Earth Group (BE), a Brooklyn-based renewable energy company, announced today the arrival of a state-of-the-art solar-powered electric vehicle charging station to Brooklyn Bridge Park — a world-class 85-acre sustainable waterfront park with iconic views of the New York Harbor and Manhattan skyline.
Designed and built by BE, the station is the first solar-powered charging station in New York City and one of only a few in the world. Brooklyn Bridge Park will use the donated station to charge its electric service vehicles (EVs) using only the power of the sun. This project greatly enhances the Park’s already impressive sustainability efforts, which include the reuse of materials from demolished buildings, use of native plant species, reintroduction of marine habitats and management of rainwater and runoff.

Renewable energy campaigners want to harness energy from wind and the sun to generate 30% of a Cornwall town’s electricity needs.
Wadebridge Renewable Energy Network (Wren) wants to explore ways of introducing hundreds of solar panels to the roofs of homes and businesses.
Wren says that the scheme could also generate £450,000 a year for the town.
The money would come from a feed-in tariff which offers a premium price for renewable energy.
‘Financial benefits’
A number of developers and landowners have shown interest in setting up solar energy farms in Cornwall to take advantage of the feed-in tariff.
Stephen Frankel, of Wren, said: “We’ve some of the best sun and wind resources in the country More »

Learning that current levels of oil production and use are not going to bring down civilisation with the ongoing crisis in the Middle East and it doesn’t fill me with relief and satisfaction which everyone seems to think it should.
I would have thought that, irrespective of Middle Eastern problems, renewable energy sources should be taken seriously, individuals, organisations and governments should champion and accept a good policy for manufacturing now, given that oil supplies are indeed finite, and seize the day and invest heavily in becoming world leaders in innovative and ever more efficient alternatives to oil.
Oil supplies from unstable regions
Competition for oil and gas in the Arctic regions are now going to increase, especially since More »

The solution to the world’s energy crisis might be found in a magnetic device that utilizes both ambient temperature and magnets to generate power. In theory, the “Searl Effect Generator” (SEG) has the potential to run completely on its own through a complex interaction between various materials, resulting in an unlimited supply of free and clean energy.
Discovered by John Roy Robert Searl in 1946, the “Searl Effect”, as it is called, effectively captures the kinetic energy generated by More »

The production of energy through the usage of wind turbines is becoming more and more common around the world and is helping to contribute to both the reduction of energy costs for millions of people as well as the reduction in the world’s reliance upon conventional fossil fuels. Here are some interesting facts about wind energy: More »
As fossil fuels continue to diminish and climate change poses an ever-increasing threat, scientists around the world are searching for new and more efficient methods of generating energy. Wind energy is one of the more promising alternative energy sources and Norwegian scientists are currently in the development stages of what promises to be the world’s largest wind turbine. As if creating the biggest wind turbine in the world was not enough, it also floats. Current plans for the world’s largest wind turbine have the machine standing 533 feet tall.
The proposed rotor diameter of this machine is 475 feet. Obviously, these gargantuan dimensions make it difficult to imagine many places able to accommodate such a device. Fortunately, the floating design makes the turbine suitable for open ocean use.
In addition to being the world’s largest wind turbine More »
