It doesn't matter. Laws of physics say energy cannot be created nor destroyed. Solar energy takes a lower form of energy to the masses.
We'd have to lower the population to about 2.1 billion (that's killing off 4.7 billion people) to live off solar power the way an American does. Harnessing wind has devastating effects on the climate. The highest form of energies would be electric and nuclear, but we have no clean ways of renewing them.
The greatest proposal I have recently been a part of is not implementable. Having a satelite beam microwaves to recievers transmiting clean energy at no cost to us. More.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
