Alternative Energy Sources and Global Warming

Global warming is among the “hottest” issues nowadays. The current climate change is the worst yet to happen. Global warming is an overall increase in world temperature which is attributed to the increasing number of greenhouse emission* trapped in the atmosphere. Searching an alternative energy source is considered a way of reducing the toxic emissions.

Greenhouse emission* can be brought forth both by natural and industrial processes. The most abundant greenhouse emission* on earth’s atmosphere are water vapor, carbon dioxide, methane, nitrous oxide, ozone and CFCs.

There are several sources of greenhouse emission*. Burning of fossil fuels and deforestation lead to higher concentration of carbon dioxide in our atmosphere. Without the trees and plants to take in the carbon dioxide emitted by burning fossil fuels, natural gas and petroleum products, all of the CO2 emitted stays in the atmosphere.

As well the use of CFCs or chlorofluorocarbons in refrigeration systems and in fire suppression systems and other manufacturing processes as well increase the greenhouse content of our atmosphere. While the use of non-organic fertilizers in agriculture as well lead to higher nitrous oxide concentrations, another greenhouse emission.

In the United States, greenhouse emission mainly come from the use of fossil fuels as energy source. Approximately 82 percent of the greenhouse gas discharge in the United States in 2006 came from the combustion of coal, natural gas and petroleum (United States Energy Information Administration). Meanwhile in Asia, Chine is expected to increase its emission of greenhouse emission because of the construction of old-fashioned power plants in its internal provinces. Currently, the carbon dioxide concentrations in the atmosphere are the highest in 150,000 years. The 1990s was most likely the warmest decade in history, while 1998 was the warmest year (Greenpeace).

Not controlling the greenhouse emission being emitted by human activity can increase global climate change the next hundred years that will be much faster than anything known and recorded in history. There are necessary steps to be undertaken to control the toxic emission that will soon be killing us.

To minimize the consumption of oil, petroleum and other fossil fuel, we should us a carbon free energy generator that are energy efficient. Energy that we use should be generated from renewable energy source, which would mean harnessing the natural energy from the sun, winds, crops, tides and waves.

Green energy is another term utilized to describe sources of energy that are considered to be environmentally friendly, which is as well similar to the renewable sources of energy.

There are numerous ways of generating electricity and energy from renewable and natural sources that generate clean and safe energy. Wind, sun, and heat can generate electricity for less price and less carbon emission than those of coal and even gas.
