Alternative Energy Source and Global Warming

Searching an alternative energy source is considered a way of reducing the toxic emissions.
The most abundant greenhouse gases on earth’s atmosphere are water vapour, carbon dioxide, methane, nitrous oxide, ozone and CFCs.

There are several sources of greenhouse gases. Burning of fossil fuels and deforestation lead to higher concentration of carbon dioxide in our atmosphere. In the United States, greenhouse gas emissions mainly come from the use of fossil fuels as energy source. Approximately 82 percent of the greenhouse gas emission in the United States in 2006 came from the combustion of coal, natural gas and petroleum (United States Energy Information Administration). There are numerous ways of generating electricity and energy from renewable and natural sources that generate clean and safe energy. Governments are taking steps to use and tap alternative energy sources as main source of energy. Alternative energy source may not be the only way to reduce the greenhouse emission that human activity produce.
