A Spanish island hopes to become the first in the world fully powered by renewable energy later this year when it launches a new wind and water energy plant, a spokeswoman said Thursday.
High-tech power plant is $5 billion bet on future of coal
Looming like a spaceship over pine and sweet-gum forest, the high-tech power plant under construction in rural Kemper County is a $5 billion wager on an energy future that includes coal.
Long-term warming likely to be significant despite recent slowdown
A new NASA study shows Earth's climate likely will continue to warm during this century on track with previous estimates, despite the recent slowdown in the rate of global warming.
Drought, fires impact ability of Amazon to hold carbon dioxide
Fires in the Amazon could jeopardize the forest's ability to soak up carbon dioxide emissions even as deforestation there slows down, according to a Penn State geographer.
US power plant emissions down, study finds
Power plants that use natural gas and a new technology to squeeze more energy from the fuel release far less of the greenhouse gas carbon dioxide than coal-fired power plants do, according to a new analysis ...
