Brown kelp macroalgae — the strange, foul-smelling seaweed so often found washed up on the Pacific Northwest’s volcanic sand beaches — could ultimately offer an almost unlimited global supply of commercial-quality ethanol or biomethane.
Reaping renewable energy from un-dammed portions of great American rivers like the Mississippi, Ohio, or even the Columbia is an idea that has been bandied about for decades.
Arundo donax, the ancient species of Giant Reed that may have hidden Moses along the Nile River more than 3500 years ago, could also go a long way in solving the U.S.' 21st century biomass to energy needs. That is, if it can overcome regulatory hurdles...
By taking full advantage of both its natural subtropical climate and its own citrus resources, Florida's fledgling biomass energy sector looks to be finally coming into its own.
In its 75-year history, modern ground source geothermal energy (GSGE) has flown so far under the radar, it might as well lie in your granddad's root cellar. But unlike root cellars, built as crude geothermal systems to preserve perishables in a static...
At least one University of Washington chemical engineer is working on a thermo-chemical conversion technology that should make renewable energy "lemonade" from a particularly problematic batch of biomass "lemons."
Aviation remains as much a part of Washington State as its eastern dry-land agriculture or the rain-soaked forests on its mountainous western fringes. But only the alternative energy industry proposes to combine the three in a regional effort to create...
At dusk outside Limon, an isolated interstate interchange on Colorado's vast eastern frontier, a string of active wind turbines lines the southwest horizon --- their red aviation warning lights almost keeping time with their rotating blades. And more...
Europe is usually the last place on one's mind when riding through miles of surprisingly desolate pine forests, stretching from the Alabama line to Georgia's marshy coast. But, in an unlikely convergence of European eco-policy and Southeastern pines,...
As ancient as the earth itself, unharnessed geothermal energy most often bubbles to the surface in geological hot spots long known for geysers and naturally-boiling mud pots.
