The most efficient gas-fired electrical power stations can achieve 50% conversion efficiency. [citation needed] Oil- and coal-fired stations are less efficient. In a conventional automobile, the following energy transformations occur: Chemical energy in the fuel is converted into kinetic energy of expanding gas via combustion
This syngas can be converted into methane, methanol, ethanol, or even synthetic fuels, which can be used in various industrial processes or as alternative fuels in transportation. Furthermore, anaerobic digestion , a biological process, converts organic waste into biogas (mainly methane and carbon dioxide) through microbial action.
Energy recycling is the energy recovery process of using energy that would normally be wasted, usually by converting it into electricity or thermal energy.Undertaken at manufacturing facilities, power plants, and large institutions such as hospitals and universities, it significantly increases efficiency, thereby reducing energy costs and greenhouse gas pollution simultaneously.
Hydrogen can be produced when there is a surplus of variable renewable electricity, then stored and used to generate heat or to re-generate electricity. [174] It can be further transformed into liquid fuels such as green ammonia and green methanol. [175]
Taichung coal-fired power plant in Taiwan, the world's largest carbon dioxide emitter [15] Electricity generation using carbon-based fuels is responsible for a large fraction of carbon dioxide (CO 2) emissions worldwide and for 34% of U.S. man-made carbon dioxide emissions in 2010. In the U.S. 70% of electricity is generated by combustion of ...
In carbon fixation, plants convert carbon dioxide into sugars, from which many biosynthetic pathways originate. The catalyst responsible for this conversion, RuBisCO, is the most common protein. Some anaerobic organisms employ enzymes to convert CO 2 to carbon monoxide, from which fatty acids can be made. [11]

An energy transition is a broad shift in technologies and behaviours that are needed to replace one source of energy with another. [14]: 202–203 A prime example is the change from a pre-industrial system relying on traditional biomass, wind, water and muscle power to an industrial system characterized by pervasive mechanization, steam power and the use of coal.
