Breeding deeper-rooted crop plants could dramatically lower CO2 levels in the atmosphere, a University of Manchester scientist claims.
More than a year after the largest oil spill in history, scientists have discovered that much of the oil was eaten by microbes, fast - but they still don't know what the microbes did with all the energy they gained.
NASA might not be looking ahead to launching anything new into space these days, but some innovative hydrogen fuel cell technology lit up operations on the ground at the 135th and final mission for the Space Shuttle Program.
Using the wrong biofuel production methods can lead to the release of toxic, carcinogenic substances, new research has shown.
Biofuels hold great potential, but they're certainly a double-edged sword.
The Obama administration has clinched an agreement with 13 major automakers to increase fuel economy to 54.5 miles per gallon for cars and light-duty trucks by 2025.
Worried about extreme weather in connection with greenhouse gases and global warming? How about rising sea levels, earthquakes, tornadoes, and nuclear generators?
Data from NASA's Terra satellite shows that, when the climate warms, the atmosphere's more efficient at releasing energy to space than believed.
A lean, mean fighting machine - that's the old expression. But by embracing new energy technologies, the U.S. military is aiming to be a lean, mean and green fighting machine.
After 10,000 fire-free years, the Arctic tundra is again experiencing wildfires, and they're contributing significantly to the world's carbon dioxide levels.
U.S. military bases are required to keep functioning even if there’s a power failure, so typically they have backup systems that run on diesel.
In what it calls a "fundamental breakthrough in heat transfer technology for microelectronics," the U.S. Department of Energy's Sandia National Laboratories has developed the "Sandia Cooler."
In Spain, a solar power plant using molten salt to store heat recently produced power for 24 uninterrupted hours.
But could there be an even better way to retain energy captured from the sun?
Could there be the beginnings of biofuel in your desperately-in-need-of-cleaning bathtub?
Airborne particles from volcanoes and the burning of fossil fuels have reflected enough sunlight to offset about a third of the current climate warming caused by carbon dioxide over the past decade, says the NOAA.
It's enough to make a geothermal engineer cry: extensive investment has allowed the oil and minerals industry to map out a good picture of the fossil fuels lurking below Earth's surface.
The Bill & Melinda Gates Foundation is funding an effort to 'reinvent the toilet'.
Forests account for almost all of the world's land-based carbon uptake, a new report shows, helping end uncertainty about just how much carbon is being stored, and where.
The world's total wind power capacity, including both onshore and offshore projects, will triple by 2017, cleantech analyst Pike Research says in a new report.
