Technology continues to advance and the rate of advancement continues to accelerate. Someday in the future we will be able to supply our energy needs through so called "clean energy" and it may not be what we envision today. At this point in time hydroelectric power is the cleanest, most reliable source of energy but there is opposition to even that. Wind generators and solar panels have a much shortwr life span than coal, natural gas, nuclear and hydroelectric generators.
Legislating and subsidizing the "green" agenda before technology has made it feasible will cause severe disruption of our economy and life style. We need to let the market dictate when that happens not the government. Hopefully the destruction of these short sighted state's and nation's economies will spare the rest of us from the same fate.
