In High School Physics, we learned about Potential Energy and Kinetic Energy. We studied some old laws such as the “Law of Conservation of Energy”.

Energy comes in different forms (e.g. Mechanical, Thermal, Electric, Chemical, Nuclear).

Alternative energy sources (e.g. Solar, Wind) were marketed with Tax Incentives.

E = M C^2 (squared) is a overly simple explanation of the generation of nuclear energy.

The A-bombs over Hiroshima and Nagasaki led to debates on the appropriate use of nuclear energy.

Doomsayers feel that Apocalypse due to Nuclear War is highly likely.

Most countries initially do not care about environmental changes caused by the production and use of energy.

Some later care too much about the environment. The restrictions and bans (e.g. on the use of fossil fuels due to potential pollution) had economic bearing on some nations.

Trends include Renewable Energy, and Sustainable Energy.
