The laws of physics.
Energy does not come out of nowhere. Oil is the stored energy of sunlight captured by plants millions of years ago. All other forms of energy (except nuclear and hydro) require that we expend more energy in its creation than we can recapture. Net gain negative.
I've often noticed that the leftist side of the energy debate tends to have some whacky and completely unscientific ideas. Things like electric cars don't use fossil fuels or lead to pollution (apparently electricity out of the wall sockets is created by magic), that we can recapture more energy in the form of hydrogen than we expend in the process of electrolysis extracting the hydrogen from the water, and that hybrid cars run on some type of power other than gasoline (apparently the electrical power in the batteries comes from magic and not from the generator powered by the gasoline engine).
Ridiculous sh!t like that. Then they like to argue that jacking the price of oil to obsence heights will somehow force these "alternative" energies. Ignorance.
There are only TWO forms of capturable energy on the planet. The sun and the earth itself. Solar (still not cost effective), geothermal (the mass of the earth itself creates heat and pressure within it), hydropower (essentially solar), nuclear (essentially solar, all heavy atoms are created inside stars), and biological/argricultural (which was what oil essentially is, but from millions of years ago). Our best hope for an alternative to oil is to GROW our fuels (vegetable oils and alcohol) and to recycle our used biomass (ConAgra has turned this into very promising technology).
But lefties don't like that because it's not clean enough ("hydrogen burns clean") and so they have us chasing fantasies.
