In general, rooftop solar can almost always provide enough ''electricity'' for a house (and even charge an [[EV]] in many cases), but not always enough [[heating]]. | In general, rooftop solar can almost always provide enough ''electricity'' for a house (and even charge an [[EV]] in many cases), but not always enough [[heating]]. | ||

Compared to [[wind power]], solar is far less land-intensive {{x|about 50x less, based on the fact that the atmosphere converts about 2% of the sun's energy (that hits the Earth) into winds}} but far more invasive to the land it ''does'' use. So [[rooftop solar]] should come first, as much as possible. | Compared to [[wind power]], solar is far less land-intensive {{x|about 50x less, based on the fact that the atmosphere converts about 2% of the sun's energy (that hits the Earth) into winds}} but far more invasive to the land it ''does'' use.
