Analysis of information sources in references of the Wikipedia article "Wind turbine" in English language version.
An onshore wind turbine that is newly built today produces around nine grams of CO2 for every kilowatt hour (kWh) it generates ... a new offshore plant in the sea emits seven grams of CO2 per kWh ... solar power plants emit 33 grams CO2 for every kWh generated ... natural gas produces 442 grams CO2 per kWh, power from hard coal 864 grams, and power from lignite, or brown coal, 1034 grams ... nuclear energy accounts for about 117 grams of CO2 per kWh, considering the emissions caused by uranium mining and the construction and operation of nuclear reactors.
These work .. by blowing hot air into the rotor blades so that the ice melts, or by using heating cables on the front edge of the rotor blades where the ice sticks. No chemicals are added to the water, in contrast to aircraft de-icing, which often involves extensive use of chemicals. The price tag for de-icing a wind turbine is equivalent to the value of two days' turbine production.
