Past decade saw unprecedented warming in the deep ocean
From 1975 on, the global surface ocean has shown a pronounced-though wavering-warming trend. Starting in 2004, however, that warming seemed to stall. Researchers measuring the Earth's total energy budget-the balance of sunlight ...
Winds of change as Seychelles embraces green power
On two islands surrounded by deep turquoise water, the blades of eight wind turbines spin, providing a rare source of green energy for the port of Victoria, the Seychelles capital.
Policy issues plague hydropower as wind power backup
Theoretically, hydropower can step in when wind turbines go still, but barriers to this non-polluting resource serving as a backup are largely policy- and regulation-based, according to Penn State researchers.
This energy-boosting region in the Sun will have a new NASA satellite watching it
How does the sun's energy flow? Despite the fact that we live relatively close (93 million miles, or eight light-minutes) to this star, and that we have several spacecraft peering at it, we still know little ...
Spanish downturn a disaster for green energy
Spain's wind turbine manufacturers are laying off workers and farmers who installed solar panels are facing ruin as austerity policies afflict the long-coddled green energy sector.
Mongolia confronts smog with launch of first wind farm
Mongolia on Thursday opened its first wind farm, a landmark $122 million project that aims to shift the country's reliance on coal and tackle the pollution choking its capital Ulan Bator.
An environmentally friendly battery made from wood (Update)
Taking inspiration from trees, scientists have developed a battery made from a sliver of wood coated with tin that shows promise for becoming a tiny, long-lasting, efficient and environmentally friendly energy ...
Energy from the windy heights
The electricity from our sockets could soon come from a high-tech device flying in the sky. The innovative research project to generate wind energy with the aid of a kite won over the "Venture Kick" jury; ...
Autonomous energy-scavenging micro devices will test water quality, monitor bridges, more
Out in the wilds or anywhere off the grid, sophisticated instruments small enough to fit in a shirt pocket will one day scavenge power from sunlight, body heat, or other sources to monitor water quality or ...
New hybrid technology set to change the future of renewables
A new hybrid technology that integrates wind and solar power generation is set to overcome many of the problems associated with traditional renewable power systems and revolutionise the green energy sector.
Google to power Finnish data centre with wind energy
Google said Tuesday it had entered a ten-year deal with a Swedish wind farm developer to power a data centre in Finland.
Cold climate wind energy showing huge potential
Wind energy capacity is growing rapidly in the cold climates of the world. According to the latest forecasts, between 45 and 50 gigawatts of wind energy will be built in cold climates by 2017, which would mean an increase ...
Wind power blows into Africa
Giant turbines churning in the wind are a rare sight in Africa—but that will not be the case for long. Until now the meagre amounts of investment in African wind energy have predominantly come from governments ...
Germany must spread cost of energy shift fairly: IEA
The International Energy Agency said Friday that Germany must shield its consumers from paying too much of the cost of its ambitious switch from nuclear power and fossil fuels toward renewable energy.
