The climate of Turkey is very suitable for solar energy as solar potential is very high, especially in the South Eastern Anatolia and Mediterranean regions. Solar is a growing part of renewable energy in the country, with solar panels generating almost 8 gigawatts (GW), or about 4%, of the country's electricity. Although similarly sunny, by 2021 Turkey had installed far less solar power than Spain. Production could increase far more quickly if subsidies for coal were abolished and the auction system was improved. Every gigawatt of solar power installed would save over US$100 million on gas import costs, and more of the country's electricity might be exported. Solar thermal is also important.
