An energy primer to increase energy literacy! from Energy Reality
This website has an overview of basic energy concepts: net energy, energy density, embodied energy, energy slaves, and peak oil.
You can go on a tour of the energy terrain reviewing the major energy resources and their transportation methods, including conventional and unconventional oil, offshore oil, natural gas, shale gas, coal and nuclear, as well as renewables such as hydropower, geothermal, biofuels, biomass, wind and solar energy.
And you can make an examination of globalized transport for moving fuel (pipelines and powerlines), and of emerging energy technologies (including hydrogen) and micropower (small-scale distributed energy generation).
