Energy is needed for: residential sector, commercial sector, industrial sector and transportation sector (cheap gas means cheap food) Fossil fuels: any fuel formed by buried dead organisms oil, coal, natural gas (contain carbon) comprise 85% of energy supply. Oil is in abundance in the middle east and northern africa. Natural gas is in abundance in russia and canada. Coal in u. s. , russia, china and india. Energy sources that produce no waste or greenhouse gases hydro, geothermal, wind and sun. Renewables are found all over the world. China has the largest wind market in the world, along with western europe. Problem: unreliable and expensive or more expensive than fossil fuels and coal subsidies make comparison difficult. Growing plants which produce fuel, ethanol corn, which makes it more expensive. Canada grows a lot of food for the world, so growing biofuels would clash with the growing of food. Post ww11 it was toted as the future, then health risks became a concern.
