Solar power has begun to transform the world’s energy system

> Solar power is now growing faster than any power source in history, and it is closely followed by wind power—which is really another form of energy from the sun, since it is differential heating of the earth that produces the wind that turns the turbines.

It's interesting to realize that the vast majority of the energy used by humans comes from the sun (with the exception of nuclear and geothermal energy). Even hydro power comes from the sun, because the sun evaporates the water which then becomes part of rivers or other water reservoirs that power hydroelectric generators.

Nuclear comes from the supernova that created all the heavy elements in our solar system. Fission is releasing energy trapped during that event. So from that standpoint, even Nuclear is solar in origin.

Well the sun didn't make those elements. Some other star did so they aren't solar. Also by that logic everything that is not a hydrogen atom would be "solar" so I don't think we can stretch the analogy.
