A fossil fuel [a] is a carbon compound - or hydrocarbon -containing material such as coal, oil, and natural gas, [2] formed naturally in the Earth's crust from the remains of prehistoric organisms (animals, plants and planktons ), a process that occurs within geological formations. Reservoirs of such compound mixtures can be extracted and ...
DTE Electric Company is a state-regulated electric utility serving 2.3 million residential and business customers throughout Southeast Michigan and the thumb region. DTE Electric's power generation portfolio includes renewable energy and Nuclear power, but is primarily generated by fossil fuels. In 2020, 32.62% came from renewable and nuclear ...
Fossil fuels made up the majority of generation, with natural gas providing 38% and coal 23%. Petroleum provided less than 1%. Natural gas as a proportion of fossil fuels has been increasing since the 90's, with coal peaking around 2008 and natural gas becoming the top fossil fuel in 2016. [12] Nuclear provided 20%, a level consistent since ...
As of 2005, it was somewhat more expensive than fossil diesel, though it is still commonly produced in relatively small quantities, in comparison to petroleum products and ethanol fuel. Biofuels are mainly used mixed with fossil fuels. They are also used as additives. The largest biodiesel consumer is the U.S. Army.
Biomass (in the context of energy generation) is matter from recently living (but now dead) organisms which is used for bioenergy production. There are variations in how such biomass for energy is defined, e.g. only from plants, [8] or from plants and algae, [9] or from plants and animals. [10] The vast majority of biomass used for bioenergy ...
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 electricity.
Pellet fuel. Pellet fuels (or pellets) are a type of solid fuel made from compressed organic material. [ 1] Pellets can be made from any one of five general categories of biomass: industrial waste and co-products, food waste, agricultural residues, energy crops, and untreated lumber. [ 2] Wood pellets are the most common type of pellet fuel and ...
Since shark skeletons were cartilaginous and lacked hard parts conducive to fossilization, typically only their spines and teeth remain. Despite occurring so early in the fossil record, Michigan's cladoselachian sharks closely resembled modern forms. Fossil shark spines found in Michigan are usually the remains of ctenacanths and cladodonts.
