The limitations of climate models

How accurate is the latest generation of climate models? Climate physicist Reto Knutti from ETH Zurich has compared them with old models and draws a differentiated conclusion: while climate modelling has made substantial progress in recent years, we also need to be aware of its limitations.

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.
