So what do u think is the min figure in % to fulfill before we can go ahead with the Nuclear power generation ? Its shame to see "educated" people like you think cannot see things beyond those mere numbers. Its about diversification,looking at all possible technologies not one but all to fullfill our energy needs. Do you know why Wind energy solar energy etc are called tech of futre ? going by your statement its apparent that you dont think these are technologies to invest in cos there % could be something like 0.01 % ? Wht is your point ?
All i see its just one step in right direction and there are lot more to be made, ex start investing in renewable energry sources and there is no 1 solution for the energy needs for the coming generations.
