The three main energy sources used int the united states are Petrollium, Natural Gas and Coal. Together, based on the chart on the previous page, the account for 80.6 percent of the total U.S. energy used. These are all non-renewable and are in high demand with only a limited supply, thus putting strain on the economy due to the necessity of the products in developing nations.
In addition to the economic strain, environment polllution is also a large issue with these energy sources. Carbon-dioxide emissions are a major culprit in the rapid global warming, which remains a long-range fossil fuel problem. Both the means to extract coal and natural gas have tremendous ramiphications on the ecosystems where the extracting is occuring. Strip mining, mining that occurs above ground in larger surface areas, destroys habitat for all living organisms . In addition, shale mining also destroys the respective area the work is occuring as well as possible polution of the water systems around for both humans and living organisms.
The United States uses 27.7 percent of its petrolium for heating and electricity in homes and business, which is about 88.8 billion gallons. In addition, 46 percent of natural gas as well as 60 percent of coal are used for electricy and heating for homes and business.
It is also important to note that some nuclear power is used, although no new nuclear sites have been built since 1970, it is still used. However, Nuclear power, although providing a large energy yield is costly to construct and maintain. In addition, it also poses a large saftey threat to those within a local radius.
