  2. Solar thermal energy - Wikipedia

    en.wikipedia.org/wiki/Solar_thermal_energy

    The largest are about 10,000 m 2 (2.5 acres), with capacities of 7 MW-thermal and solar heat costs around 4 Eurocents/kWh without subsidies. [9] 40 of them have nominal capacities of 1 MW-thermal or more. The Solar District Heating program (SDH) has participation from 14 European Nations and the European Commission, and is working toward ...
