1 Introduction: an introduction to world crises related to energy and the environment, and the potential for good solutions.

2 Energy and civilization: the relationship between energy, life, and human civilization, easy energy science, life’s dependence on energy flows, civilization’s progress with the energy of the Industrial Revolution, and the 21st century crises of global warming and energy consumption.

3 An unsustainable world: global warming and its terrifying implications for water, agriculture, food, and civilization; depletion of economical petroleum reserves, deadly air pollution from burning coal, increased competition for natural resources from a growing population, and the solution of new energy technology, cheaper than coal.

4 Energy sources: the character and cost of current and principal emerging energy sources: coal, oil, natural gas, hydropower, solar, wind, biomass, and nuclear.

5 Liquid fluoride thorium reactor (LFTR): the history and technology of liquid fuel nuclear reactors, the Oak Ridge demonstration molten salt reactors, thorium, LFTR, the denatured molten salt reactor (DMSR), builders, and possible contenders for energy cheaper than coal.

6 Safety: the safety of molten salt reactors, comparisons to alternative energy sources, radiation risks, waste, weapons, and fear.

7 A sustainable world: environmental benefits of thorium energy cheaper than coal: reduced CO2 emissions, reduced petroleum consumption, synthetic fuels for vehicles, hydrogen power, water conservation, desalination.

8 Energy policy: current confused policies; failure to reduce CO2 emissions, subsidies, recommendations, leadership.
