Global warming and climate…

Global warming and climate change is caused by all introduction of heat into the environment from sources outside nature. Fossil fuel adds new heat because it comes from underground, both direct release from burning and indirectly from GHG's elevating C02. For example coal, and fossil oil, could be replaced by wood, and plant oil which were trees/plants absorbing C02 before being made into fuel. ,(which means coal fired plants could have been switched to wood)

Nuclear generation is clean in the sense of not producing GHG's. However nuclear generation comes from inside atoms and 100% of its energy - both 75% released at source and 25% when electricity is used. How much direct heating causes global warming compared to GHG's is still a matter of debate, but the reality is Ontario nuclear releases numerous atomic bombs worth of heat per yr, to the environment while hydro by comparison releases NO new heat (since natural energy simply diverts energy in nature towards humans.)

Ontario pursuit of wind energy was stupid. Being inspired by wind energy in Europe where there is little opportunity for hydro, is a mistake since Ontario is filled with hydro potential. Energy must be tailored to the natural resources of the area that needs it. There is no need for Ont to pursue the irregularity of wind when hydro offers a continuous resource that can even store energy by controlling the outlet of a reservoir. For example the Trent-Severn waterway offers a great deal untapped hydro resources. Do not flirt with nuclear or wind because its sexy, if it is a bad choice.
