There's many things out there, and all have pros and cons.
Saline power: Almost impractical due to output compared to cost.
Wind: Doable, but requires enormous windmills and are expensive to maintain.
Solar: Very expensive and requires a roughly 14x70 feet solar array just to power a normal house.
Hydrogen: Inexpensive, but is a heavy CO2 polluter.
Hydro: Most common renewable energy resource, but requires flooding canyons and everything inside that canyon.
Electric vehicles are rather silent, but the energy needs to come from somewhere. Most innovative vehicle I've seen runs on frying oil and grease. There's also natural gas vehicles as well as propane. The nat gas ones, like the electric, can be refueled at home. Like others, I've heard about vegetable oils being refined, but I'm afraid the Oil Lobby will do everything in their power to block any such initiative by use of the House Ways and Means (budgets and funding for everything) and Energy Committees, irrespective of who's holding office.
