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.

prices have fallen since they were built. Even in places with a carbon price, such as the EU, existing gas-fired power stations remain economically viable, partly due to increasing restrictions on coal-fired power because of its pollution.
