Solar energy in the United States is becoming a major part of the nation's power sector as installation costs decline, Energy Secretary Ernest Moniz said.

Building-integrated solar photovoltaic modules are fast catching up in the rapidly evolving construction business where emphasis on energy efficiency and self-reliance are becoming increasingly popular.

Researchers have developed a solar cell that is able to directly split water. It does not produce electricity in a first step and split the water in a second step, but rather only has one step.

The Environment Ministry will begin a model project in which surplus electricity generated from renewable energy sources, such as wind and solar power, will be utilized to produce hydrogen for fuel-cell vehicles.

More than 15,000 Australian businesses have now installed solar power to reduce their energy bills, and there is the potential for tens of thousands more to follow suit if the Renewable Energy Target (RET) is left as legislated, the Clean Energy Council said Monday.

Solar power has made incredible progress here in the U.S. According to a new report from Environment America. In the last 10 years, solar panel capacity has increased more than 120-fold. In just 2011 to 2013 alone, solar power has tripled.

The tolling of the evening bell signals the end of the day’s classes at Donyo Wasin primary school. For a few adept pupils like Sotik Leleno, however, it ushers in the time for their private studies under the glow of solar powered lighting.

Japanese conglomerate Marubeni Corp. said Thursday it signed an agreement to build three solar power plants near the country's western coast.

Inner Harbor Water Wheel can pick up 50,000 pounds of trash and debris every day, using solar power and water current to run.

The Department of Energy announced Wednesday it has awarded $10 million to be split between six research and development projects that will focus on thermochemical storage technologies for concentrating solar power (CSP) systems.

Solar power, however, is a free, renewable and abundant resource. Today solar energy is an inexpensive and innovative option for treating waste that is becoming more widespread and accepted.

To boost the use of Concentrating Solar Power Technologies (CSP), the Ministry of New and Renewable Energy (MNRE), Government of India, is implementing a UNDP - GEF supported project on “Market Development & Promotion of Solar Concentrator based Process Heat Applications in India”.

The Kagoshima Nanatsujima Mega Solar Power Plant, built by the electronics manufacturer Kyocera, boasts postcard views of Kagoshima Bay and Sakurajima volcano. It’s also Japan’s largest, with a capacity of 70 megawatts.

Andrew Greenfield checks his home’s solar power output against consumption through his computer and mobile phone dozens of times each day.

Harvesting power from the wind and the sun is nothing new. We've seen flying wind turbines and solar power plants that aim to provide clean renewable energy.

The British project planner Sustainable Renewable Technologies (SRT, Bilston Glen, UK) has been nominated for the Solar Power Portal Award for a solar photovoltaic (PV) system installed on a pyramid-shaped office building.

Thanks to its low latitude and low percentage of cloudy days, the United Arab Emirates (UAE) is an ideal location for capturing solar energy.

Power-One Inc. will showcase its first residential energy storage solution at the Solar Energy UK trade show in Birmingham, England from October 8th-10th, 2013.

Indonesia and the US have signed a Memorandum of Understanding (MoU) on cooperation in green technology on the sidelines of the Asia-Pacific Economic Cooperation (APEC) meetings from October 1 – 8 in Bali, Indonesia.

Research meteorologist Edwin Campos and his colleagues at DOE's Argonne National Laboratory have partnered with IBM to build a forecasting technology based on IBM's Watson supercomputer, made famous by its 2011 victory over human champions on the television quiz show Jeopardy!.
