The reason why we still use fossil fuels is because the alternatives are too expensive and people are unable to afford it as well as the fossil fuels are easy to get to so business can gain access and sell on. In the future hopefully we can use the alternatives but for now it has to be fossil fuels.
Alternatives fuels are fuels that are not made from fossil fuels (coal, oil and natural gas).
Two alternatives are Hydroelectric and Geothermal.
because fossil fuels are a finit resource and some day in the not to distant future we will run out of it.
Wind, solar, water (as in hydroelectric dams), and Biofuel (corn-based ethanol) are major alternatives to fossil fuels.

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.
Fossil fuels
Basically two reasons.1) Fossil fuels won't last forever - we will run out of these fuels pretty soon. 2) Fossil fuels produce contamination, including filling the atmosphere with greenhouse gases.
There are many other alternatives to using our fossil fuels, get online silly! Google things like wind, solar energy, and water energy....
Fossil fuels-including coal, natural gas, and oil-are formed from the fossilized remains of prehistoric plants and animals, and fossil fuels provide about 95% of the world's total energy. Alternative fuels are better for the environment and often better for the economy than fossil fuels.
