Wind offers potential to fill our energy needs

Wind energy – both on land and offshore – has been falling in cost almost as dramatically as solar power. It’s down well over 90% since 2000.

The relevant technologies are still improving. Furthermore, wind has some advantages over other forms of electricity generation, including other renewable generation systems. For instance, wind generators can be installed in far more places than hydroelectric or geothermal generation plants, both of which require very specific geology.

On average, a well-sited wind turbine will produce about twice the amount of energy over a year as a photovoltaic solar...
