Non-fossil fuels, renewable fuels.
Fossil fuels are organic compounds that are made from concentrated elements found in the Earth's crust. These organic compounds include petroleum oil, coal, and natural gas.
Most likely because fossil fuels are not minerals. They are ultimately composed of organic matter which came from living things that died and became buried under sediment. Through a lot of time and a great amount of pressure the fossil fuels were developed. This is also why fossil fuels are considered non-renewable resources because it takes so long to make them. That's all :) JAE HERMOSA
Burn less fossil fuels
the scientific definination for fossil fuels if buger eater
they release fossil fuels in to the atmosphere, fossil fuels is mainly coal and they pollute the atmosphere and rivers as you said.
fossil fuels are mainly used in power plants to create energy some of these fossil fuels could be coal etc. Fossil fuels burnt make 2 different gasses witch rise and make rain witch is call acid rain . Witch can damage wildlife and other things. The truth is that fossil fuels are mainly used to feed thing that are destined to become fossils. Anything else is a myth as oil is abiotic.
HydrogenNitrogenSulphur
they provide the most energy efficiently
Fossil fuels come from fossilied plant matter in the ground. Alternative fuels are alternatives to fossil fuels, and these are mainly carbon fuels that take their carbon from carbon dioxide in the atmosphere (as fossil fuels do) but on a carbon cycle with a much shorter term. An example is wood, which can be burned as more trees are growing and absorbing carbon dioxide.
Mainly two reasons. (1) The fossil fuels will eventually be used up. (2) Fossil fuels cause pollution.
carbon and hydrogen
mainly sulfur and its oxides.
Gasoline and fossil fuels are hydrocarbons. Hydrocarbons are composed of the hydrogen (H), oxygen (O) and carbon (C). MTBE and ethanol components to gasoline are also hydrocarbons.
fossil fuels
47% is natural gas, 28% is coal (2010 figures).
coal mainly and may many other fossil fuels
