Renewable Energy

It's been three months since the tragic oil spill in the Gulf of Mexico. Millions of barrels of oil have been leaking from the underwater well up to the present, severely affecting both aquatic and human life around the gulf. The spill has already reached shorelines in different US states. As far as history is concerned, BP's oil spill is the worst to ever occur. It would definitely take years to finish the cleanup.
So who's to blame for the environmental tragedy? The obvious answer would be British Petroleum - the London-based energy company behind the oil exploration activity in the gulf. Investigations reveal that the energy company did some cost-cutting measures weeks prior to the explosion that caused the spill. But setting the obvious facts aside, one culprit that remains unnoticed is humanity's dependence on oil products. Even though it's not a valid excuse, the cost-cutting measure BP made follow the logical concept of a business: spend less and earn more. In order to prevent similar accidents from happening in the future, perhaps it's time to stop looking from the micro-scale perspective. Looking at a general perspective, the key to preventing this kind of accident is the shift from oil to renewable energy sources.
The gulf spill is just one of the wake-up calls for humans to start looking for alternative sources of energy. The world is now at the brink of a technological revolution. Green sectors have experienced a boom triggered by the worsening global warming. Climate scientists describe global warming as man-made, caused by increasing carbon emissions. Man's solution to the climate problem is renewable energy.
Solar energy is the most popular source of renewable energy. Harnessing the power of the sun is nothing new to man. Solar panels have been existing for decades, capturing and using energy from the sun to power homes, cars and even airplanes. Just recently, the solar aircraft named Solar Impulse attempted its first night flight using stored solar energy. The individuals behind the project aim to develop a technology that would allow air travel without the use of conventional airplane fuel. The same technology also applies to hybrid cars. Automobile manufacturers have developed engines run on electricity generated from harnessed solar power. Households also benefit from solar energy. More and more homes are now being by the energy of the sun, which is converted into electricity. Such progress means less coal will likely be burned to produce traditional electricity. Again, solar technology works on the premise that no fossil fuel, no carbon emission.
Another reliable alternative source of energy is the wind. Several Western and European nations have the embraced the technology of windfarms that harness the energy of the wind. Wind turbines are constructed on strategic locations to generate electricity as the wind blows. The generated electricity can be used to power commercial and residential establishments.
Last but not the least is water. With hydropower technology, electricity is generated using buoys that activate electrical generators upon contact with waves. The electricity generated is transmitted to storage units through underwater cables.
With the planet entering a deteriorating phase, man needs to look for other means to sustain life without destroying the very place he calls home. Even though fossil fuel remains the main and most valuable source of energy, man needs to source out energy alternatives before global warming hits top gear and becomes irreversible. So far, the only solution available is to replace traditional fossil fuel technology with green technology that use renewable energy.
