Solar energy has numerous advantages

September 2, 2010 | By Articles are the property of their respective Authors In environment | Comments(0)

Every coin has two edges. Likewise, solar energy too has pros and cons. There are numerous advantages of solar energy. It has disadvantages too. But the truth is that the advantages of solar energy outweigh the disadvantages. There is more number of advantages as compared to the disadvantages. This article is all about the numerous advantages of solar energy.

The major advantages of solar energy are-

Solar energy is unanimous. There will never be a drought of this energy. In winter season also, a moderate amount of this energy is available. That means this is a renewable source of energy that is consistent and will never end. This fact completes the search for a source of energy that is ever lasting.

Solar energy is absolutely free. Nobody has to pay anything to get the benefits of this energy. It is absolutely free. Although a small investment have to be done at the starting but afterwards no body has to pay anything to get the energy. It can satisfy the energy requirements effectively with no expenditures.

Solar energy is highly Cost-effective. As compared to all other natural resources present, this energy is highly cheap. There is no doubt that the solar photovoltaic is expensive. But due to the advancement in technologies, scientists have made the generation of power from this energy in a very cost-effective manner. The solar hot water panels have been improved in recent years and its cost has highly reduced. The prices of other resources like coal, oil mans gas are increasing day by day but on the other hand, energy derived from sun has become the alternative for all these resources as it is cheaper.

These are some of the major advantages of solar energy. This energy can be utilized by everybody.

The Effects of Global Warming and What it Means to You and Me

June 28, 2010 | By In Global Warming | Comments(0)

Have you ever listened to discussions and read articles about global warming and wondered why the resource person or the writer appears so emphatic and urgent in their call for fighting it? Well that is because global warming is an urgent problem that needs immediate action and resolution before it gets worse and could spell the end of human life and civilization as we see it today.

Broadly speaking, global warming is the steady increase of the atmosphere’s and ocean’s average temperature. And before you go saying ‘Big deal’ to yourself and scoff at the near-catastrophic predictions made by scientists and advocates, consider first some of the expected effects of global warming to our environment and to our very lives.

One of the most pronounced effects of global warming would be glacial retreat, in which glaciers in the Arctic region may be steadily melting. This translates to elevation of sea levels all over the world, raising concerns over obliteration of small islands and even countries. Global warming is also attributed to influence precipitation, leading to the possibility of increased flooding in some parts of the world and increased drought elsewhere. What’s scary about these projected changes is the complete inability of man to counteract and prevent them once these events start happening.

But then again, global warming effects are not solely manifested in the environment. Consider the effect of increased drought and flooding to food supply, and ultimately, to food consumption. Agriculture is one large sector expecting to bear the worst of the brunt of global warming, with lesser and lesser produce and crops expected to be harvested in the next decade or so. Now that is really scary, considering we all get a large portion of our food supply from farms.

Weather experts are also predicting extreme weather events due to global warming, ranging from severe snowstorms to intense cyclones and hurricanes in tropical areas.

The increase in the average temperature of oceans in our planet also means dwindling in the supply of our other food source. The rest of the world might not come to realize how fragile most of the sea organisms are and expected changes in temperature would bring about extinction to most of them. Carbon dioxide, the main culprit of global warming, is also expected to acidify ocean waters, leading to more extinction and disruption of the food web.

It is also worth considering the impact of global warming on human health as well. With increasing surface temperature, heat waves are expected to occur more frequently, possibly endangering children and the elderly. Many pathogens proliferate much faster in warm environment. Increasing atmospheric temperature could very well mean faster proliferation of these pathogens that would cause numerous diseases and illnesses to humans. There is also expected spread of fatal tropical diseases as the world becomes warmer and warmer, placing those living in temperate regions at higher risks.

The mentioned risks and dangers are but overviews of the complexity and gravity of the problem that is global warming. A lot of resources and references have been published and produced on the subject matter and it’s time people should sit up and make effort to learn more. With increasing knowledge and understanding, the fight against global warming would no longer seem to be overwhelming and insurmountable. And as cliché as it may sound, this is one fight nobody can ever win alone, so concerted efforts are certainly needed and cooperation from all sectors would be very much welcome.
