Earth has only three significant sources of energy.
First is geothermal energy from Earth’s molten core and decaying radioactive minerals in Earth’s crust. This energy moves continents, powers volcanoes and its heat migrates towards the crust, warming the lithosphere and the deep oceans. It can be harvested successfully in favourable locations, and radioactive minerals can be extracted to provide large amounts of reliable heat for power generation.
Second is energy stored in combustible hydrocarbon minerals such as coal, oil, gas, tar sands and oil shale. These all store solar and geothermal energy collected eons ago and they are the primary energy sources supporting the modern world and its large and growing populations.
Third are radiation and gravitational energies from the Sun and Moon which are captured by the biosphere as heat, winds, tides, rain, rivers and in biomass such as forests, crops and animals. These are the natural “Green” energies that support all processes of life and still support a peasant existence for some peoples.
Green zealots believe that we can and should run modern societies exclusively on “Green” energies, and they have embarked on a war on hydrocarbons. They need to be told that their green energy favourites are just stealing from the biosphere – they are not as green as they claim.
