You're kidding, right? Bio, thermal, oceanic, wind, liquid coal, nuclear. Your problem is not wanting to give up the combustion engine.
Nope.
If gearing up oil exploration is pissing in the ocean, then these 'alternatives' are spitting into the ocean... upwind.
Bio - shown to have a larger carbon footprint (hate to use the term but speaking 'their' language as a courtesy) at greater cost per unit of energy produced, with the lovely side effect of raising taxes on the poor & middle class through higher food costs.
Thermal - can't even supply all of Iceland's power needs.
Oceanic - figure out a way to store & distribute oceanic energy, the Nobel will be yours.
Nuclear - no problem, go right ahead & request a permit.
The only two 'alternatives' that stand a chance of making a dent in our oil consumption any time soon are wind and coal. The technology to harness & store wind energy on an individual home basis is getting close to being cost effective. We already have the technology to scrub coal such that it burns with nearly zero emissions, but the EPA won't hear of it.
The nubbin of the problem is that any 'alternatives' have to become inexpensive and widely available and achieving that is no simple thing. If the government subsidizes alternatives without the actual cost per unit of energy going down, we've just spun our wheels. Things that reduce our energy consumption will certainly help, but a way to power our transportation system has to be maintained and for the foreseeable future, that way is oil.
