Fight Global Warming

Jay Slough - Monday, February 22, 2010

The future looks bleak and ominous if we do not rectify our ways of wasting energy sources. The earth’s climate is rapidly changing as evidenced by the more frequent occurrence of heat waves and droughts; polar caps are melting and sea level is rising. These are not mere insinuations, these are backed by extensive research and scientific studies. Here are some facts: the overall atmospheric temperature has risen by 1°F since 1900; the overall surface temperature has likewise risen by 1°F over the last 100 years; the sea level has risen by 10-15 cm.; and the United States alone contributes about 25% of the world’s carbon dioxide emission.

But what exactly is global warming and what are possible solutions to effectively address the problem? Simply put, global warming refers to a marked increase of carbon dioxide and other green house gases in the atmosphere. Carbon dioxide traps heat and acts like a blanket warming the earth. We all contribute to the accumulation of these so called ‘greenhouse gases’ in many ways, including emissions from the vehicles we drive to the power plants that generate non-renewable power for our daily needs. All of these things that we rely on and normally take for granted are taking their toll on the planet, making it a less friendly environment for us and for future generations.

A lot of people have put up various organizations in the fight against global warming. However, the solution to global warming can only be truly effective if everyone joins in to fight it together. Experts say that in order to control global warming and still meet long term energy demands, a “reduction by replacement” policy must be adopted. This policy basically outlines the gradual replacement of fossil fuels “down the road” by the incremental development of an alternative and renewable energysource.

One of the best sources is solar energy. With the recent advances in solar energy development, it has become evident that it is the most practical and feasible solution for a clean environment, a stable climate, and to meet the long term global energy demand. Since time immemorial, energy for humanity has always been based on harnessing the energy from the sun. The sun belongs to everyone and to all nations. It does not generate certain foreign policies, just clean and unlimited energy. With augmentation by wind and other natural sources, the technical solar challenges can be successively addressed.

The pioneering works of several organizations and the current solar industry have come up with photovoltaic cells that convert solar energy into electricity. Corporations have produced photovoltaic cell products such as calculators and even solar battery chargers for laptops and iPods. Larger voltaic cells have been devised for solar panels for residential heating and cooling. Scientists have designed and engineered simple solar power collectors for residential heating or the more sophisticated ones that focus heliostats for solar furnaces. The possibilities are endless, and this renewable energy can reduce the load on the fossil fuel powered power plants, thereby reducing greenhouse gases in the atmosphere and ultimately slow down or reverse the adverse effects of global warming.
