The practical options for energy range from the standard fuels, natural gas, petroleum (or oil), and coal. Fossil fuels are referred to as nonrenewable energy sources because, once used, they are gone. Scientists are exploring the practicality of other sources called renewable energizes. These include sun, wind, geothermal, water, and biomass. The renewable power resources are very important in long range energy planning simply because they will not be depleted. It was on February 27th, 1892 that Diesel filed a patent within the patent office in Germany for his method and design for that combustion engine. He sourced contracts from firms that manufactured machines and began his experimentation stage. During this stage he constructed working types of his design in an attempt to construct the most efficient engine of that time.
