Global environmental challenges
California utility PG&E and solar power company Solaren say they have inked a first-of-its-kind deal to produce renewable solar power from space satellites beginning in the year 2016.
PG&E, one of the largest electric utilities in the United Sates, says on its in-house blog, Next100, that it is seeking approval from state regulators for a power purchase agreement with Solaren, which it says can provide 200 megawatts of clean, renewable energy — enough to power some 140,000 California homes — over a 15 year period.
Solaren says it will generate the power using solar panels on Earth-orbiting satellites, transmit it back to Earth through a radio frequency to a recieving station in Fresno County, then convert it into electricity which would be fed into PG&E’s grid.
Though the project sounds exotic (read: expensive), PG&E says the benefit of solar energy from space is that – since the satellites are consideraby closer to the source with no clouds in the way – its 8 to 10 times greater than that on Earth and can be harnessed 24 hours a day, no matter the season back home.
