If Humanity were to suddenly come to its senses and stop relying all together on fossil fuels and start relying on wind powered and solar energy sources, wouldn't this lead to some sort of climate change?
The reason why I am wondering if this would happen is the following:
Large scale reliance on Solar energy means that a lot of heat that was being absorbed directly by the earth would now be channeled into energy useful for humans. Presumably this would be lead to a non-negligible decrease in the temperature of the surface of the planet, as well as to a decrease in the amount of solar energy being reflected back into the atmosphere, both of which would lead to some changes in the climate.
Large scale reliance on Wind powered energy sources would lead to changes in global wind patterns - pulling energy out moving air masses that use to lead to tropical storms and hurricanes, maybe even effecting things like the trade winds and large ocean currents like the Gulf Stream. This would effect ocean temperatures and rain fall patterns and lead to dramatic climate change as well.
Are these realistic scenarios, or are solar and wind powered energy sources truly safe?
