- Solar: photovoltaic, solar thermal, solar chimney. Prospective: solar power satellite and stratospheric solar array
- Wind: land-based wind turbine, off-shore wind turbine. Prospective: jet-stream sky windmills
- Ocean: wave, tidal, ocean currents
- Hydro-electric
- Nuclear: nuclear fission. Prospective: nuclear fusion and accelerator-driven thorium-fuelled energy amplifier
- Geothermal: shallow geothermal heat pumps, volcanic related geothermal, deep geothermal
- Biomass: vegetable oil, compost methane, fermented crop waste, algae, sustainable wood, and clean burning of organic waste, animal dung and rubbish
The energy available from solar and geothermal alone far exceed our current and likely future energy requirements and could sustain humanity indefinitely. Also steadily increasing energy efficiency, due to improved system design and increasing cultural awareness should become a significant factor in our energy use.
