The climate change debate continues.

IF  some forms of nuclear are cost  effective, people will  use it. Some don't have a lot of choice. The FACTS will decide. To me waste Heat seems to be Part of it. Waste heat goes into the Environment as does the waste heat from Ice and steam engines because they are far from 100% efficient, unlike Electric motors. Nev

Electric motors and converters still release heat as does anything that makes the electricity to power them. Would be interesting to see how much a WTG releases with gearboxes, muliple electric motors converters and hydraulic systems/ MWh.

Electric motors typically run at between 85% & 95% efficiency. Energy lost is mostly heat. Older AC induction motors usually run between 75% & 85%. Modern EVs convert over 77% of the energy at the wheels. The rest is lost to heat and friction. Fossil fuelled cars are very inefficient when converting the energy in the fuel to the wheels at between 12% and 30%. Again the rest is lost to heat and friction.
