...AND CHEAPER...:

As countries around the world seek to reduce their carbon emissions, what if there were a way they could generate significantly more power from one of the fastest-growing sources of renewable energy, without the need to buy any expensive new equipment or clear more land?

Scientists at MIT say they've figured out how to do just that with wind power.

After testing complicated computer models, they've shown that adjusting the rotor blades of turbines at a wind farm -- a change that would reduce the efficiency of an individual turbine if it stood alone -- can significantly increase the overall power produced by the wind farm.
