Edited sentence: But, most important, the energy available above our atmosphere meets  the needs for an increased quality of life  worldwide by virtue of the fact that it is potentially endless.Eventually the needs for land for these projects will clash with the interests of conservationists intent on keeping desert ecosystems and coastal views intact.It can be beamed to any location in which a receiving apparatus, a rectenna, is built.It is shut down completely overnight, requiring additional means to store energy for that time.Real estate on earth is limited, say the Space Solar Power advocates.Space solar power advocates point out that wind and solar are intermittent and require hydrostorage or other replacement when they are not available.Space solar power does not require an expensive terrestrial distribution infrastructure.Space solar power, say the SSP advocates, is available 24/7.Terrestrial solar energy--earth-based solar energy--suffers another disadvantage.Terrestrial solar power and wind farms take large amounts of space.The solar energy that falls on a square millimeter of collection apparatus in space has six times the energy it has if collected on the earth's surface.The space approach is called space solar power and is advocated by groups like the National Space Society, the National Space Foundation, the Foundation for the Future and the Space Development Steering Committee.This is an advantage for newly-electrifying rural areas in countries like China and India
