I have been using the following outline to lecture + write about energy, including in a book manuscript. Would welcome any + all suggestions on modification or expansion. Thanks.
Non-Animate Energy Systems Categorized
Energy efficiency + demand flexibility faster, easier, cheaper:Â
negawatts + flexiwatts + negabarrels
Current solar energy [almost] all sustainable energy types: biofuels,
hydropower, wave power, ocean thermal energy conversion [OTEC],
photovoltaic, concentrating solar, wind
Ancient solar energy consists of fossil fuels: coal, natural gas,Â
conventional oil, bitumen oil, kerogen oil
Nuclear fission possible due ancient type II supernovae producing
Th-90 + U-92 + Pu-94 [basis of fuel cycles]
Geothermal energy originates from compressive accretional
formation of planet, coupled with extensive suite ofÂ
radioactive substances decaying over eons
Tidal energy derives at root solely from gravitational interactionsÂ
between Sun + Earth + MoonÂ
Piezoelectric + thermoelectric + thermomagnetic + triboelectric
generation — niche technologies from materials science
Hydrogen [fuel cells] + electricity [secondary forms of energy]
