The most important energy sources of our future
Regenerative or renewable energy refers to the provision of energy from sustainable sources such as sun, wind, water, geothermal energy or biomass. They are available in almost inexhaustible quantities. In contrast, the supply of fossil fuels such as coal, oil, natural gas and conventional nuclear fuels is continuously decreasing as consumption continues. These fossil fuels belong to the non-renewable energy sources. Once they have been burned in a power or heating plant, they are no longer available. They do not regenerate, they are devalued.
However, the growing world population and the advancing technological development of mankind are leading to an enormous demand for energy, which is constantly increasing. It is also known that emissions of the greenhouse gas carbon dioxide (CO2) from the combustion of oil, natural gas and coal are very high and, according to current knowledge, are the cause of global warming.
