subject: An Explanation Of Renewable Energy [print this page] Which is better, delving into a static, finite energy source and eventually depleting it altogether, or using a renewable energy source that will never run out and will always reliably replenish itself? The answer that the latter power source is better should be obvious. But when you add in the factor of a renewable resource that also results in clean energy that does little damage to the earth and doesn't contribute to global warming, the answer should not only be obvious, but imperative.
Renewable and clean energy therefore automatically excludes resources such as coal, natural gas and oil. While it's true that all of these are originally derived from plant or animal material, all of which are technically "renewable," the processes that form these energy sources take millions of years. That takes them well out of any time frame for renewable power that could be used by human beings right now.
Add to this the effects of global warming from releasing these hydrocarbons into the atmosphere, and these types of energy sources are not desirable anyway. They are the reason alternative energies are needed.
In the gradual move away from non-renewable hydrocarbon power sources, many other resources have begun to be developed. Renewable wind energy, for example, can be harnessed by wind turbines, and solar energy panels collect sunlight and convert it into usable power. Geothermal power from the heat in the earth is now being developed, and of course, clean hydro power from falling water, such as Niagara Falls, has been a viable renewable energy for over a century.
Green energy solutions are not just trendy, but have a real impact on the earth and its inhabitants. Not only do these renewable energy resources leave the earth less damaged, but they help people live in greater harmony with nature, instead of feeling like they are at war with it. Oil, gas and coal result not just in damage to the earth from the extraction methods necessary to acquire them, but their long term effects on the world are even more damaging. It is far better to use renewable, clean resources that will give the earth and living things a chance for a healthier future.
