Something was destroying the motor bearings of the centrifuge and ventilation fans at the Red Trail Energy Ethanol Production Plant in North Dakota. Plant maintenance personnel realized the bearings on these large motors were failing long before...
Ever since French physicist Jacques Arsene d'Arsonval first proposed tapping the ocean's thermal energy for power back in 1881, experts have proclaimed that Ocean Thermal Energy Conversion (OTEC) was an idea whose time would never come. Although...
The three leading offshore renewable energy technologies are winds, waves, and tides. While widely different in form, these technologies all employ an energy capturing mechanism using either sea or wind. Although a relatively new technology,...
The United States Department of Energy recently projected that in order to meet a national goal of obtaining 20% of our electricity from wind generation by 2030, utilities must integrate some 300 GW of wind generation onto the grid. To accommodate...
The next 10 years will be crucial for the development of the wave and tidal industry. With the right research and technology, this may be seen in the future as the decade of deployment-the period in which wave and tidal technologies moved into the...
The world’s appetite for energy continues to grow, as does the technology available to capture energy. A new system has been developed for eco"friendly hydroelectric power generation that facilitates the efficient, systematic transport of...
Hydroelectric. Hydropower. Hydro. Whatever you call it, it’s all the same: a renewable, non-polluting, and reliable source of energy—an ideal solution to our nation’s immediate demand for renewable energy sources. Yes, hydropower...
By Leah S Karlov & Joanna Grossman The year-end deadline is quickly approaching for new renewable energy projects to start construction to qualify for the federal cash grant in lieu of the 30% investment tax credit. Because renewable energy...
By Daron Threet & Larry Eisenstat On April 28th, 2010, the federal government approved the Cape Wind project after nine years of regulatory review. The significance of the Cape Wind approval cannot be overstated, as the project is now poised to...More about
Wave energy developer Aquamarine Power recently unveiled the design of its Oyster 2 wave energy convertor, which will be built in Scotland this summer. The new 800kW device will measure 26 metres by 16 metres and will deliver 250% more power than...
