Green technology may be the wave of the future at some point but it is untenable and unsustainable at the present time.
The technology and products developed using this technology are way too expensive to make the technology viable at the present time.
Oil, gas and coal therefore will be needed for much longer time and what we really need to do is start going a lot more nuclear and to develop recycling for nuclear waste.
Or the way of the past. Like sailing ships and whale oil. Obama is like Ahab chasing after Moby Dick.
