Yes, I am very aware of all that seeing I have done a few threads on this subject in the Energy forum, so do me a favor and research before preaching to me about subjects I have already posted on.
The fact is Nuclear and Hydro electric along with other technology can benefit humanity and nothing is perfect.
With Nuclear you could have another three mile island incident and with Hydro you run the risk of failure of water become scarce.
In the end it will take a combination of things and let me be clear Oil will deplete sooner or later, so we better start looking hard at the alternative ways to lower ourselves.
