Alaska and Wave Energy

Located on the Gulf of Alaska, the 750 kW Yakutat Wave Energy Project is set to make life easier for locales who have so far had to rely on diesel prices as high as $8 per gallon, thanks to the 1,000 mile journey the fuel has to make by road to get there.[read more]


The Case for ARPA-E: The Government's Role in Bridging the Valley of Death

November 11, 2013 by Clean Energy Leadership Institute

ARPA-E and Government Investment


This year Congress has sought to slash the budget of the Advanced Research Projects Agency, with Congress proposing cuts of over 80%. ARPA-E has embarked on several rounds of successful funding for breakthrough clean energy tech, helping companies bridge market barriers.[read more]


Hydro and Ocean Power: Untapped Renewable Resources? [WEBCAST]

September 21, 2013 by Jesse Jenkins

Hydropower is an efficient, predictable, and affordable source of energy that produces no greenhouse gases and already generates a fifth of the world's electricity - but is it an overlooked tool in the effort to meet the world's growing energy needs sustainably?[read more]

Energy Projects Seem Less Urgent in A Post-Energy-Crisis World

September 17, 2013 by Geoffrey Styles

Post-Energy-Crisis World


To someone living in 1974, the idea of mass protests to block a pipeline for importing oil would have seemed incomprehensible. Yet the current opposition to so many different energy projects can also be viewed as a consequence of recent energy successes on a broad front.[read more]

The small French island of Mont Saint-Michel, a UNESCO World Heritage site, is famous for its fast and forcefully rising tides. The famous writer Victor Hugo once claimed them to be as fast as galloping horses. Tidal energy is all about capturing this energy of the sea. While large tidal projects have been proposed for centuries, actual...[read more]

New Energy Sources: Possibilities and Prospects

January 18, 2013 by Mark Caine

Energy transition is not just an imperative: it’s a certainty. But while it’s certain that we’ll continue to transition towards a new energy mix, far less certain are the nature of this mix and the speed of our transition. Also uncertain, though certain to be profound, are the impacts of this transition on human societies and the economies and earth systems that sustain them.[read more]
