 A global movement towards the generation of low-carbon renewable energy is underway to help reduce global greenhouse-gas emissions.The theory that fossil fuels formed from the fossilized remains of dead plants by exposure to heat and pressure in the Earth's crust over millions of years was first introduced by Andreas Libavius "in his 1597 Alchemia [Alchymia]" and later by Mikhail Lomonosov "as early as 1757 and certainly by 1763".The first use of the term "fossil fuel" occurs in the work of the German chemist Caspar Neumann, in English translation in 1759.
