Fossil Fuel Use The nation of the United States is the country that leads all others in the use of fossil fuels. Fossil fuels are those that are formed in the ground over a period of millions of years formed from dead plants and animals. Oil, natural gas, and coal are fossil fuels and we use a lot of them! Fossil fuel use by humans is the largest source of emissions of carbon dioxide which is one of the greenhouse gases that allows radiative forcing and contributes to global warming. When you burn fossil fuels, they let out a large amount of carbon dioxide. The atmospheric concentration of CO2, a greenhouse gas, is increasing. This raises concerns that solar heat will be trapped and the average surface temperature of the Earth will rise in response. We use fossil fuels to power our vehicles, heat and cool our houses, and generate electricity. As we said, it takes millions of years to form certain fossil fuels and over-use of them has resulted in a concern that we will soon deplete our supply. Fossil fuels are non-renewable sources of energy, so once they are used up, they are gone. In the United States, we use about twelve barrels of oil – the most valuable fossil fuel - per person per year. That is why we are so dependent on foreign oil to meet our energy needs. While the United States does have its own supply of oil, it doesn’t compare to what the Middle East has to offer. So in order to meet the demand, we have to increase the supply. Pretty much the only way to do that is to buy it from other countries – usually either Venezuela or Saudi Arabia. The increased levels of fossil fuel use in this country has given birth to the green movement urging people to start exploring alternative forms of energy to avoid depleting our fossil fuel supplies completely. But a bigger reason is because the greenhouse gas emissions are causing global warming that can have a huge effect on the lives of people all over the world – not just in the United States. If we can reduce our use of fossil fuels and start looking at alternative sources of energy, we not only improve the quality of the environment, but we also reduce our dependence on other countries for our energy resources. The phrase “American Made” has always meant something in the U.S., but when it comes to decreasing our fossil fuel use and becoming self-sufficient with alternative fuels, it can mean so much more!
