The days of constructing energy-hogging buildings could soon be something considered so 2010.
Are big solar and wind – like oil and gas – ready to compete to use resources on federal lands?
The US Department of Defense (DoD) is currently engaged in a "hard push" to significantly reduce dependence on fossil fuels in an effort to shrink risks on the battlefield.
California regulators have approved five power purchase agreements that could boost the state's renewable energy capacity by 1,088 megawatts (MW) and produce 2,927 gigawatt-hours (GWh) of energy.
There is a moment in Bill Jaeger's latest biofuels paper when his scholarly posture crumples a bit and he seems to want to shout loud enough for policymakers in Washington, D.C., to hear him all the way from Corvallis, Oregon.
Theoretically, the maximum efficiency of today's silicon solar cell is approximately 31 percent, because much of the solar energy that hits the cell is lost as heat.
Progressives have never been very good about admitting - let alone claiming - victory.
It might have been a biomass cogeneration plant in Brazil, or a wind farm in Mexico.
Or perhaps that solar thermal plant in Morocco.
MIT researchers say a hybrid solar-thermoelectric system they're working on could provide a big advantage over conventional solar cells or solar thermal systems, particularly for household use.
The United States domestic solar industry continues to be a bright spot in an otherwise down economy, according to a recent report by Solar Energy Industries Association and GTM Research.
Renewable energy production in the United States has surpassed the production of nuclear power for the first time, a government study reports.
For small islands, the incentive to end dependence on imported fossil fuels and embrace renewables is powerful.
Uncle Sam’s not writing the check, but a coming infusion of cash into the cleantech sector via the private sector is nothing to sneeze at.
Kyocera has been doing some interesting things of late, mainly around solar.
Publisher McGraw-Hill, along with NJR Clean Energy Ventures (NJRCEV), announced plans recently to build what is said will be the largest privately-owned and net-metered solar project in the Western Hemisphere.
China, China, China - yup, we know, we write a lot about that country's green technology advances.
It isn't a perfect world over there, with trade issues around wind power and all being just one hiccup of many.
While the GOP controlled House was busy slashing clean energy program budgets last week, a Senate subcommittee was occupied with drafting a bill that, among other efforts, aims to make solar power system installations faster and cheaper for the nation.
Citizens of the Granite State are no strangers to sustainable living, nor to fine micro-brewed beer.
One of the biggest problems with large-scale solar power is the vast amount of land area required. Deserts such as the Sahara have been suggested, but a team from Israel's Solaris Synergy and France's EDF Group have another idea - put them on the water.
We've seen New Energy Technologies announce a series of advances in its attempt to turn windows into solar panels, and now the company says it has a working, 1-square-foot see-through glass prototype capable of generating electricity.
