Google announced on Thursday that it is investing 75 million U.S. dollars in a wind farm in the Midwestern U.S. state of Iowa, making its total investment in clean energy projects to nearly 1 billion dollars.

The US Energy Information Administration has just released its “Annual Energy Outlook 2013” report with projections for US energy markets through to 2040. The report shows that growth in the country’s energy production is outpacing the growth of consumption.

Maybe storage isn’t the ultimate key to a renewable energy future.

Starting next January, the price of purchasing renewable energy voluntarily through monthly utility bills will spike to all-time highs, thanks to recent decisions rendered by the Public Service Commission of Wisconsin (PSCW) on two popular “green pricing” programs.

The rap on some green building efforts is that they can tend to be more expensive than using conventional designs and materials. However, a fire department in North Carolina turned this argument on its head recently when it completed its new LEED Gold certified fire station not only on time but $2 million under budget.

Generating electricity from water is not a new thing. Hydro power stations have already sprung up across the world in China, United States and Canada. However, scientists will not stop exploring advanced technologies for further improvement to benefit people's lives.

Powering the battery on a car with an electric motor and battery pack usually requires plugging in at night and sometimes during the day.

Renewable energy could fully power a large electric grid 99.9 percent of the time by 2030 at costs comparable to today's electricity expenses, according to new research by the University of Delaware and Delaware Technical Community College.

Sometimes there’s mention in the press that wind farms harm wildlife.

Apple has decided to double the size of the fuel cell power plant at its North Carolina data center.

A proposed “Solar Zone” could be coming to California, if the US Bureau of Land Management (BLM) has it’s way.

In a move that could put wind energy on equal economic footing with traditional fossil fuels, GE (NYSE: GE), Virginia Polytechnic Institute & State University (Virginia Tech), and the National Renewable Energy Laboratory (NREL), will begin work on a project that could fundamentally change the way wind blades are designed, manufactured and installed.

Green technologies are becoming more and more popular in all aspects of home and industry design. As New York rebuilds after the tragic events of 911, a new era of architecture is being unleashed.

Solar-cell fabrics may soon be a reality, thanks to new research from Penn State.

Covering nearly 300 football fields in a remote patch of desert, the Shams 1 solar project carries off plenty of symbolic significance for the United Arab Emirates.

Rice University scientists have unveiled a revolutionary new technology that uses nanoparticles to convert solar energy directly into steam.

A new method for capturing carbon dioxide (CO2) emitted by power plants could reduce their CO2 emissions by more than 90%, while utilizing less energy and incurring less expense than former approaches.

By using common materials found pretty much anywhere there is dirt, a team of Michigan State University researchers has developed a new thermoelectric material.

Fifteen solar panel vehicles, some that look like small space ships, raced across Chile's Atacama desert as part of a contest to build low-cost environmentally-friendly cars.

In three studies published in the current issue of Technology and Innovation – Proceedings of the National Academy of Inventors, innovators unveil creative technologies that could change our sources of energy, change our use of energy, and change our lives.

A spike in shale oil and gas production is revolutionising the energy sector and risks weighing on prices of conventional crude, according to industry experts.

To celebrate World Toilet Day on November 19, researchers at Columbia University's Engineering School, working in Ghana with Waste Enterprisers Ltd., the Kwame Nkrumah University of Science and Technology (KNUST), and the Kumasi Metropolitan Assembly, are launching a pilot facility to convert fecal sludge into biodiesel fuel, thereby addressing a ubiquitous societal problem and concurrently producing renewable, cost-effective sustainable energy.

Getting a wind turbine to a decent height to allow it to reach stronger winds than those found closer to the ground generally means sitting them atop a tower

Wetlands are estimated to account for around six percent of the earth’s surface and a new Plant-Microbial Fuel Cell technology developed at Wageningen University & Research in The Netherlands could see some of these areas become a viable source of renewable energy.

Ontario, Canada has carved out a niche for itself as a hub of green technology. One of the latest clean tech innovations to come out of that province is DARWIND5, a vertical axis wind turbine (VAWT).
