Is global warming due to heat produced by power plants?
 Question: In this question we will try to find out is it possible that global warming results from the energy released in burning fuels.In how many degrees centigrade does our planet heat up every day due to the power invested in it by the power stations? Use: Earth heat capacity (model assumption): c=4200 J/liter °C Earth radius (known since ancient Greeks): R=6400km Power stations power: P=1013 Watt (for more details, click the second point on the map) Note: this is a large numbers calculation, do it with care.For more information click the first point on the map. This will lead you to the largest nuclear power station in the world and to a detailed explanation on the calculation you are required to do.

 About 1/100 C per day. This effect causes earth to heat in 1 C every three years and it is a major part of global heating
 Less than 1 part in a million degree per day. This effect is negligible.
 About 1/10 C per day. This is the main cause of global warming. Any energy source but the sun will cause the same problem
 About 1/1000 C per day. Currently, it is not a problem, but should mankind, using nuclear power plants, willincrease by a factor of 10 power production, this is a real danger
