Types of fuel
There are all kinds of fuels, there are biomass, fission, fusion, and fossil fuels. Biomass belong to the group biofuel, which is a group that repersents "junk energy". Fossil fuels are hydrocarbons, which is basically coal and natural gas, formed from ancient plants and animals by exposing to the big pressure in the absense of oxygen in the earth's crest over a hundred million years. Fission and fusion are nuclear fuel and they are quite dangerous, although this type of energy is renewable. The fusion fuels tend to be light materials such as hydrogen.
