Global warming is one of the latest issues nowadays. The present global warming is the worst yet to occur. Global temperature rises is an overall increase in world temperature which is assigned to the skyrocketing number of CO2 emissions besieged in the atmosphere. Looking an alternative power source is regarded as a way of reducing the harmful emissions.

Greenhouse gases can be produced both by natural and industrial processes. The most abundant greenhouse gases on earth atmosphere are water vapour, carbon dioxide, methane, nitrous oxide, ozone and CFCs.

There are a couple of sources of CO2 emissions. Burning of carbon-based fuels and deforestation lead to higher concentration of carbon-dioxide in our atmosphere. Without the trees and plants to take in the CO2 emitted by burning ordinary fuels, natural gas and petrol products, all the CO2 emitted stays in the atmosphere.

Also the utilization of CFCs or chlorofluorocarbons in refrigeration systems and in fire suppression systems and other producing processes also increase the greenhouse content of our atmosphere. While the employment of non-organic manure in farming also lead to higher nitrous oxide concentrations, another greenhouse gas.

In the U. S. , greenhouse gas emissions mainly come from the employment of carbon-based fuels as power source. Roughly 82 p.c of the greenhouse gas emission in the US in 2006 came from the combustion of coal, natural gas and petrol ( US Energy Info Administration ). In the meantime in the East, Chine is anticipated to extend its emission of greenhouse gas thanks to the development of old school power plants in its internal provinces. Now , the carbon-dioxide concentrations in the atmosphere are the highest in 150,000 years. The 1990s was probably the warmest decade in history, while 1998 was the warmest year ( Greenpeace ).

Not controlling the greenhouse gas being emitted by human activity can increase global warming the subsequent hundred years that’ll be faster than anything known and recorded in history. There are obligatory steps to be done to control the dangerous emission which will shortly be murdering us.

To decrease the consumption of oil, petrol and other ordinary fuel, we should use energy efficiently. Energy we use should be generated from replenish-able energy source, which would suggest employing the natural power from the sun, winds, crops, tides and waves.

Green energy is another term used to describe sources of energy that are considered to be environmentally friendly, which is also 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.

Shifting the world attention to alternative fuel source aside from depending on carbon-based fuel is among the solutions in resolving the extreme global warming. Greenpeace cited that with green energy and using it smartly, can deliver half of the planet energy desires by 2050. Greenpeace also cited that it is possible to reduce carbon-dioxide emission to about fifty % in the next 43 years.

Governments are taking steps to use and tap alternative energy sources as main source of energy. The European Union leaders made an agreement in March 2007 to ensure that 20 percent of their nation energy should come from renewable fuels by 2020. This is part of their effort to cut carbon dioxide emissions and other greenhouse gas. There are even governments offering incentives to their residents who are using green energy.

Alternative power source won’t be the sole way to cut back the greenhouse emission that human activity produce. There are simple ways we are able to do to contribute in reducing toxic gas emission and offset global warming.
