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 modern industrial societies and the vast populations dependent on them.
Third are radiation and gravitational energies from the Sun and Moon which are captured by the biosphere as heat, winds, tides, rain, rivers…
