An Enphase microinverter Traditionally, photovoltaic arrays have been arranged in series of strings, with one or two centralized inverters changing the module’s DC electricity to AC electricity.

Sunverge battery backup could help in situations like SandyWeeks after subtropical storm Sandy ravaged the northeast coast, the hundreds of thousands still without power were asking if solar could be a solution.

A week after sub tropical storm Sandy made landfall in New York, thousands are still without power in their Rockaway Beach neighborhood homes.

From a distance, a wind farm can seem almost placid, turbines turning slowly, steadily, churning out electricity. But there's more to it than meets the eye.

Austrian manufacturer MagnaSteyr has adapted technology developed for the Ariane rocket to build clean-burning cars that can use hydrogen instead of petrol for fuel.

Between now and 2020 the green sector could create upwards of 3 million jobs in the U.S. That’s according to a new report from CleanEdison.

On 22nd August, the Ministry of Construction held the approval of the draft "National Strategy for Green Building Development in 2030, with a vision to 2050

Located in the tropics, Vietnam still cannot take full advantage of its sun and wind resources to generate electricity. This has been attributed to the unreasonable mechanism which is unattractive to investors.

The International Atomic Energy Agency (IAEA) will continue to closely cooperate with and assist Vietnam in the field of its charge, especially nuclear safety and security.

It may seem as though the German plains are all but tapped out when it comes to wind energy production. To refute this theory researchers are sending stunt kites into the skies to harness the wind and convert the kinetic energy generated into electricity.

The Government of Azerbaijan and the World Bank (WB) have started a dialogue in order to develop the country's renewable energy resources, WB Baku Office told Trend on Wednesday.

The world's largest offshore wind farm has delivered its first power to the grid, marking a major milestone for the flagship project in the Thames Estuary.

s green building a trend in major global sporting events? It certainly was at the London Olympics, which saw all of its permanent structures built to green standards, and materials from all of its temporary buildings recycled or reused upon deconstruction.

It doesn’t look like much. In fact, you could say Columbia Island is a concrete slab of an eyesore in the Long Island Sound off the coast of New Rochelle, N.Y. But soon it will be a 6,000-square-foot residence that’s off the grid and self-powered by solar and a solar storage system.

We’ve covered some of the innovations in green tech stemming from the University of Nottingham in recent years, particularly in the realm of wind power

London of late has been rolling in the electric car news. The goal in that major European city of lowering its carbon emissions from greener vehicles is well under way through efforts like brand new all-electric taxi fleets and increased electric vehicle usage at nearby Heathrow airport. Now comes word of free electric vehicle charging points being offered as part of a trial to better understand the impact of EV use on the electricity network.

The Energy Information Administration (EIA) reports that grid-connected solar photovoltaic (PV) solar installations topped 3,536 MW in 2011.

A wind generation facility that its producer, Pattern Energy, calls the largest wind generation facility in the Caribbean began producing energy on the island of Puerto Rico Oct. 28.

Solar power installations are well worth the investment, even in snowy climates, according to new research from Michigan Technological University. The albedo effect caused by white snow cover actually helps to increase solar panel efficiency (counter to what many of us might have thought).

Research shows newly developed solar powered cells may soon outperform conventional photovoltaic technology. Scientists from the National Renewable Energy Laboratory (NREL) have demonstrated the first solar cell with external quantum efficiency (EQE) exceeding 100 percent for photons with energies in the solar range. (The EQE is the percentage of photons that get converted into electrons within the device.)

A green revolution to make EU energy almost totally carbon-free by 2050 would generate 3 trillion euros ($3.9 trillion) in fuel savings, a report commissioned by environmental campaigners said.

GreenRoad app alerting drivers to inefficient manoeuvres targeted at delivery and company car fleets A new smartphone-based tool promises to cut emissions and improve safety by alerting drivers to erratic or inefficient driving.

A variety of Japanese businesses participated in a seminar on October 26 to discuss new financial mechanisms for applying energy saving technology to buildings and hotels.

A contract to construct the 260 MW Trung Son hydropower station, which is the first to be funded by the World Bank, was signed in Hanoi on October 22.

The Trung Son Hydropower Co Ltd, a subsidiary of Electricity of Viet Nam (EVN), yesterday signed a deal worth close to VND3 trillion (US$150 million) with a joint venture company to build and equip the Trung Son Hydropower Plant.
