Windmills are becoming a source of [[renewable energy]], in 2004 generating 6,740 MW, or 6% of American [[electricity]]<ref>Wind Industry Statistics|http://www.awea.org/faq/wwt_statistics.html</ref>.  The total cost of electricity from windmills is more than from other sources (hydro, coal and nuclear), and windmills do not provide reliable sources of power (as the wind does not blow all the time) so back up generation is still required. 

[[Netherlands]] is popularly known for their quaint, picturesque windmills (which were also used to pump water to keep the land dry), but [[Denmark]] also has their share.
