There really aren't any practical ones right now. Solar power is only available in daylight, in good weather, and has some environmental problems; they fry birds in flight, and blind pilots. Wind power is even harder on the bird population, and is even less reliable than solar. Large wind turbines tend to fall down with monotonous regularity. Nuclear fission works well, until you have a giant earthquake and a tsunami that washes away the backup generators....
Hydrogen fusion power is about 20 years away, and has BEEN "20 years away" for about 40 years now.
Space-based solar power satellites will probably work, except right now we have no spacecraft, and we're angry with the Russians who are the only people who have any. "Electric" cars are actually coal-powered, because a big percentage of the US's electrical power is coal.
It's all well and good to talk about rooftop solar panels and backyard windmills, but you can't run an industrial civilization that includes steel mills and aluminum smelters on rooftop solar panels.
Coal adn wind.
Oil shale and tar sands
Solar and wind renewable energy, of course. Oil shale and tar sands
Renewable energy (solar, wind, water, hydro, tidal and wave, geothermal, ocean thermal, biomass, biofuel and hydrogen).
plastic
Solar energy is stored in coal and petroleum.
Solar energy, geothermal energy, wind, petroleum, coal, uranium (nuclear fuel).
Those not derived from petroleum or coal, such as solar engergy, wind energy.
Petroleum, coal (including peat).
Coal, Petroleum, Sun, Wind, Nuclear power, Geothermal power, Natural Gas, and Biomass are all energy resources.
