In our modern lives, we are dependent on a regular supply of energy.
Fuels are necessary to drive cars and other means of transportation.
We need heating, warm water and, of course, electricity.
To date, the energy demand, which is growing around the world, is still mainly covered by fossil fuels like crude oil, natural gas and coal.
Fossil energy carriers are a form of biomass which was deposited many millions of years ago. Their extraction takes a lot of effort and in some cases puts a considerable strain on the environment.
