Why people connot understand still that only if we let go old system our society can change into using renewable sources? People are afraid it might cause serious economic and social shocks. Yes, it can, so what! Nature works that way. For example, if you have dry branch on the tree because of some bacteria, you need to cut that branch, it in order to prevent all tree to die. Our economy system is like that. If we need to go through some shock, let it be, to rejuvenate our society where we won't kill our planet that provides all the life. As anyway this oil based industry is big shock for our planet and us as humans but still we are ignorant to see that. Look the oceans, animals, forests, all planet is suffering...

Nikola Tesla found solution for free energy more than 100 years back. But greed is still one of the dominant feeling among establishment, and for that reason, normal people suffer and pay still for something that nature can provide in abundance.

I believe we are waking up as humanity, step by step. It is a slow and long process, but it is happening. Let us do whatever each of us can from our sided. Be more aware for beginning. Namaste.
