WOOD CHIPS: The are waste that can be utilized for making electricity. The disadvantage is that the Utility companies are lobbying to stop all competition.
USED GREASE: Can be simply used to make Biodiesel to run vehicles and stationary engines. The disadvantage is that Big Oil is lobbying to eliminate all competition!

(1) Sunlight
-- Advantage: Once you have the equipment, it's free, and there's no limit to it.
-- Disadvantage: Not good on cloudy days, and would take way too much to power a vehicle (weight would be prohibitive). However, it can be practical for home/industrial use.
(2) Hydrogen fuel cells
-- Advantage: Only exhaust from hydrogen-powered vehicles are drops of plain water.
-- Disadvantage: Must be handled properly or is extremely flammable/explosive (however, development of fuel cells is already making it safe to use, even now)

Biomass, Hog barns produce alot of manure this can be burned to create energy. The advantage is you use a resource that is considered a waste and make energy from it. Disadvantage is it still emits carbon dioxide

Find a way to harness the 13,000 terawatts of solar energy the moon receives. Just 1% could satisfy the Earth's total energy requirements.
