Alternative fuels, also known as non-conventional and advanced fuels, [1] are fuels derived from sources other than petroleum. [2] Alternative fuels include gaseous fossil fuels like propane , natural gas , methane , and ammonia ; biofuels like biodiesel , bioalcohol , and refuse-derived fuel ; and other renewable fuels like hydrogen and ...
There is a limited amount of fossil fuel inside the Earth. Since the current world energy resources and consumption is mainly fossil fuels, society is very dependent on them for both transportation and electric power generation. The Hubbert peak theory predicts that oil depletion will result in oil production dropping off in the not too distant ...
In addition, burning biomass still produces carbon emissions, although much less than fossil fuels (39 grams of CO 2 per megajoule of energy, compared to 75 g/MJ for fossil fuels). [107] Some biomass sources are unsustainable at current rates of exploitation (as of 2017). [108] A CHP power station using wood to supply 30,000 households in France
To heat buildings, alternatives to burning fossil fuels and biomass include electrification through heat pumps or electric heaters, geothermal energy, central solar heating, reuse of waste heat, and seasonal thermal energy storage. [199] [200] [201] Heat pumps provide both heat and air conditioning through a single appliance. [202]
They offer a prospect of increased market competition and oil price moderation. A healthy supply of alternative energy sources will help to combat gasoline price spikes and reduce dependency on fossil fuels, especially in the transport sector. [5] Using transportation fuels more efficiently is also an integral part of a sustainable transport ...
"Energy transition” can mean different things to different people—and the oil and gas industry wants it to include fossil fuels
Renewable fuels are fuels produced from renewable resources. Examples include: biofuels (e.g. Vegetable oil used as fuel, ethanol, methanol from clean energy and carbon dioxide [1] or biomass, and biodiesel), Hydrogen fuel (when produced with renewable processes), and fully synthetic fuel (also known as electrofuel) produced from ambient carbon dioxide and water.
Biofuels are different from fossil fuels in regard to carbon emissions being short term, but are similar to fossil fuels in that biofuels contribute to air pollution. Burning produces airborne carbon particulates, carbon monoxide and nitrous oxides. [83] The WHO estimates 3.7 million premature deaths worldwide in 2012 due to air pollution. [84]
