nstead of generating electricity at sea and sending it to shore, a different kind of wave energy device is in the works in Australia, and it promises to deliver not only emissions-free electricity, but also emissions-free desalinated water.The technology, called CETO after a Greek sea goddess, is being developed by Carnegie Wave Energy Limited, and their upcoming 2MW pilot project near the Perth Wave Energy demo site will be the first wave powered desalination plant in world

Since 1998, the Pelamis development programme has covered all aspects of the design from the fundamental concept refinement through to accelerated cycle testing of individual components for reliability.

During the first phase of Pelamis development prior to full-scale operations in 2004, extensive numerical modelling and analysis and a range of technology demonstration models at different scales were used to understand survival characteristics in extreme waves and verify the accuracy of our simulations

During the first half of 2008, the United States, for the first time, generated more wind energy electricity than Germany, despite the fact that the smaller European country still has more turbines than we do. Germany has enough turbines to collect about 22,000 to 23,000 megawatts of power, while the United States has a capacity of about 18,000 megawatts,

hen a modern day person hears the term “solar energy” they often think about solar panels that are mounted on roofs in sunny neighborhoods. Find out how to slash your electric bill by 75% with little out of pocket expense. Although this is a part of solar energy, there is much more to it.

Waves are caused by the wind blowing over the surface of the ocean

. Ocean waves contain tremendous energy potential. Wave power devices extract energy from the surface motion of ocean waves or from pressure fluctuations below the surface.  

Then we’ll present diagrams and discuss photovoltaic solar, solar hot water, and concentrated solar power. The easiest way to think about these is: am I using solar energy to heat water (solar hot water and CSP) or am I converting sunlight directly into electricity (photovoltaic cells)? Solar Energy Diagram #1 – Insolation

The BLM manages 20.6 million acres of public lands with wind potential. The BLM has authorized 39 wind energy development projects, including connected-action projects that include electric transmission support authorizations, with a total approved capacity of 5,557 megawatts, enough to supply the power needs of over 1.5 million homes. 

For more than a decade, wind energy has been the fastest growing energy technology worldwide, achieving an annual growth rate of over 30%. In the United States, the current total installed capacity is over 60,000 megawatts of wind projects.

Ethanol, for instance, is an alcoholic biofuel easily distilled from sugary or starchy plants. It has been used to power cars since Ford’s Model T and, blended into conventional petrol, constitutes about 10% of the fuel burned by America’s vehicles today.

Solar power is different: although it too uses a lot of space, solar panels can be very well integrated into the urban environment, so they have virtually no impact on land use and cause very little visual pollution.
