Transition from fossil fuels to renewable energy
Fossil fuels (coal, gas and oil) are the biochemical remnants of plants and animals which used solar energy to grow. So fossil fuels energy is actually fossil solar radiation.
All renewable energy (hydro, wind, solar, ocean) originates in solar energy. Therefore, we need to change from fossil to present day solar energy.
Although they both have the same origin, the present one is clean but discontinuous and difficult to store, while the fossil one is polluting but already stored.
There is competition and a lot of unfair practices between the renewables and the fossil fuel industry. In fact, there would be mutual interests for their co-operation.
All energy sources have changed during history, but none disappeared. Burning wood, which was the first source of heat and later replaced by fossil fuels, still exists.
We need to invent better and cheaper storage for renewable energy, to replace fuels (fossil or biofuels) which have high energy density and are available at any time and place.
However, fossil fuels are much more valuable in the chemical industry than for burning. Many processes from steel making to producing plastics are impossible without fossil fuels.
Since the organic molecules of fossil fuels would be too expensive to reproduce from other sources, it is a pity to burn them while their value for the chemical industry is higher.
Renewable energy can produce power and heat, but cannot be used in the chemical industry, thus they should be the preffered energy source.
The fossil fuels should mainly be used in the chemical industry, and they should only complement as energy the renewable sources when the latter are not available.
Additionally, since using fossil fuels in the chemical industry prevents burning them, we also solve most of the greenhouse gas problem.
This interdependence and complementarity of the two energy sources require co-operation and advanced planning, for mutual benefits.
