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:
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,
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 of
radioactive substances decaying over eons
Tidal energy derives at root solely from gravitational interactions
between Sun + Earth + Moon
Piezoelectric + thermoelectric + thermomagnetic + triboelectric
generation — niche technologies from materials science
Hydrogen [fuel cells] + electricity [secondary forms of energy]

The Energy Central Power Industry Network is based on one core idea - power industry professionals helping each other and advancing the industry by sharing and learning from each other.
If you have an experience or insight to share or have learned something from a conference or seminar, your peers and colleagues on Energy Central want to hear about it. It's also easy to share a link to an article you've liked or an industry resource that you think would be helpful.
