Where is all the money going to come from? Wind power requires consistant wind. Natural gas powered vehicles require conversion kits. Solar panels costs are for the rich.
For the last time, nobody is banking on wind to meet ALL our energy needs. It’s a part of the solution, not the solution.
I believe the hope is that cars will be manufactured to take natural gas from the start. This will be much more economical than converting exisiting gas cars.
Photovoltaic solar panels are expensive currently, but concentrating solar thermal plants are not. A mix of solar thermal and wind will save us tons of fossil fueled energy.
