Carbon dioxide - our salvation from a future ice age?

Mankind's emissions of fossil carbon and the resulting increase in temperature could prove to be our salvation from the next ice age. According to a new research article by researchers from the University of Gothenburg, the current increase in the extent of peatland is having the opposite effect, cooling down the climate.

High-tech tools tackle wind farm performance

Researchers at the U.S. Department of Energy's (DOE) National Renewable Energy Laboratory (NREL) are learning how to better understand these issues and are working toward effective solutions for the wind industry. Their goal is to maximize turbine performance and minimize structural loads, which will ultimately result in lower-cost wind energy. Toward that goal, NREL researchers are leveraging the lab's supercomputing resources and have developed high-tech modeling and simulation capabilities.

Researchers propose new building guidelines to clean up city air

The huge energy needs of skyscrapers mean that these towers are not only office buildings, they're polluters with smokestacks billowing out toxins from the rooftop. Our cities are dirtier than we think. New research from Concordia University just might clean them up.

Biofuels from algae hold potential, but not ready for prime time

Scaling up the production of biofuels made from algae to meet at least 5 percent – about 10 billion gallons – of U.S. transportation fuel needs would place unsustainable demands on energy, water and nutrients, says a new report from the National Research Council.

Wind energy yields major environmental and public health benefits for Colorado

Wind energy in Colorado each year saves a billion gallons of water while avoiding emissions of air pollutants equivalent to that produced by half a million cars. Between 2000 and 2011, production of electricity from wind energy in Colorado grew from zero to 4.7 million megawatt-hours (MWh), and is now producing nearly 10 percent of the state's electricity.
