PRINCIPLE OF CONCENTRATING SOLAR POWER
Heat from concentrating solar thermal collectors drivessteam turbines, gas turbines or piston engines, to deliverelectricity or combined heat and power. E.g.:
concentratingsolar collector
steam turbine& generator
utility grid
steam power

POTENTIAL OF CONCENTRATING SOLAR POWER
1 km² yields up to 200 - 300 GWhe/year
1 km² equals 50 MW coal or gas plant
1 km² saves 500,000 bbl of oil / year
1 km² avoids 200,000 tons CO2 / year
