In some industries, the word energy is used as a synonym for energy resources, which refer to substances like fuels, petroleum products, and electricity in general. This is because a significant portion of the energy contained in these resources can easily be extracted to serve a useful purpose.
Energy portal; These are modes of energy production, energy storage, or energy conservation, listed alphabetically. Note that not all sources are accepted as legitimate or have been proven to be tappable. Bus running on soybean biodiesel. Atomic energy; Alternative fuel; Alternative fuel vehicle; Banki turbine; Battery (electricity) Bioalcohol ...
Methanol and ethanol fuel are primary sources of energy; they are convenient fuels for storing and transporting energy. These alcohols can be used in internal combustion engines as alternative fuels. Butane has another advantage: it is the only alcohol-based motor fuel that can be transported readily by existing petroleum-product pipeline ...
Biomass (energy), biomass used for energy production or in other words: biological mass used as a renewable energy source (usually produced through agriculture, forestry or aquaculture methods) Bioenergy, energy sources derived from biological material Solid fuel, forms of bioenergy that are solid; Biofuel; Energy crops
emergy – “energy memory” all the available energy that was used in the work of making a product directly and indirectly, expressed in units of one type of available energy (work previously done to provide a product or service); the energy of one type required to make energy of another.
As an energy source, biomass can either be used directly via combustion to produce heat, or converted to a more energy-dense biofuel like ethanol. Wood is the most significant biomass energy source as of 2012 [103] and is usually sourced from a trees cleared for silvicultural reasons or fire prevention.
A power source is a source of power. Most commonly the type of power referred to is: Power (physics), the rate of doing work; equivalent to an amount of energy consumed per unit time Electric power, the rate at which electrical energy is transferred by an electric circuit; usually produced by electric generators or batteries
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.
