There are several 'alternative' energies discussed among people.
Hydrogen
Ethanol
Natural Gas
Propane
..
However, have you wondered why they are all either fluids or gaseous ? The car industry has previously been working on electric vehicles, with better and better energy storage systems (batteries).
Now producing the fuels mentioned above costs more electricity than their actual energy output. Why would someone want to spend 1kw to produce a fuel with 0.8 times that energy![]()
It is simple. While electric cars don't waste energy, the energy they consume can hardly be controlled by large oil companies. As long as a fuel is fluid, it can be sold at as stations. Electric vehicles can be plugged at home, and that's what the oil companies don't want.
If you take all the money that is being spent on research for alternative energies, you could make batteries that are green, and which can store a lot of electricity.
