The Cheapest Way to Power Your Car

Petrol/gasoline at $3 per gallon????? - the present real cost at the pump should be around US$117 per gallon, because it is being heavily subsidised after being extracted from the Planetary Energy Bank, and not returned, that energy being mostly wasted as heat, trying to warm up the interplanetary void.

Hydro is cheapest, in almost every Country - hurrah.

The big problem is energy transmission and conversion losses.

These immediate problems need to be overcome, before dirty cars and trucks can be used efficiently....

I doubt that $0.91 for hydropower is accurate either.

There are lots of hidden costs in that figure too

There are usually a bunch of subsides in hydro projects. The beneficiary's rarely pay the actual costs.

There are long term effects on watersheds. on both sides of dams.

The world wide economy has been running for years on undervalued resources!
