Renewable Energy Facts – The Truth About Renewable Energy
Renewable energy is simply energy that is gathered from naturally renewable sources, that are constantly replenished on an ongoing basis, such as wind, sun, rain, waves, tides, and geothermal heat; or even from man-made renewable energy sources, such as nuclear energy, hydroelectric power, biomass, fossil fuels, and the like. This renewable energy can be obtained either from natural sources (such as wind, water, and sun) or from man-made ones (gas, coal, and oil). The renewable energy being discussed here is electricity generated through an electrical generator, using one of many technologies currently in use to do so. In this article, we’ll take a look at the types of renewable energy currently being used in electricity generation, and their benefits and drawbacks, as well as some possible alternative forms of energy which may someday replace these more traditional methods.
The first alternative to fossil fuels
which is often considered when discussing renewable energy sources is solar power. This is because the sun provides free and unlimited energy, while also being readily available all year round. While solar power does have its limitations, mainly in terms of storage, it remains to be one of the most powerful renewable energy sources to date. Unfortunately, for electricity generation in urban centers and other areas where there is a lack of natural sunlight, especially in areas close to the equator, the reliance on solar power becomes less desirable over time.
The second option, biofuels, is derived from plant and animal matter.
With a higher density than other renewable energy sources, such as coal or oil, biofuels can be used to supplement other types of renewable energy. For example, Ethanol, biodiesel, and fuel made from vegetable oil are all viable alternatives to fossil fuels for the transportation industry, because they are more abundant and widely available. Although using biofuels to replace fossil fuels in this capacity has some significant drawbacks. For instance, ethanol contains alcohol, which is a toxic gas that produces during the process of fermentation and can pollute the air if used at larger concentrations.
Other renewable energy sources
that can significantly supplement electricity in your home include biomass and geothermal fuels. Biomass energy can be utilized in place of fossil fuels in your home, if you do not want to go through the additional steps of having fuel delivered to your home, or building an experimental fuel cell to start using it directly. Geothermal fuels come from underground heat sources in your environment and are extremely reliable and abundant. Some countries like France, Australia, and Canada use geothermal power as their primary source of renewable energy. Using renewable sources in your electricity and heating power needs is considerably cleaner and greener than traditional methods, and offers a wide range of advantages, although they do require a high degree of flexibility and planning to implement efficiently.
Perhaps the most interesting alternative to fossil fuels
and renewable energy sources is solar energy. The sunlight is constantly available in large portions of the world and can be easily harnessed for use as renewable energy. The photovoltaic cells in the solar panels are designed to trap the sun’s rays using photovoltaic materials, which have been developed by scientists and technology developers over the last thirty years. Although this technology has been around for decades, only recently has it started to be commercialized, and the cost of solar panel production is coming down dramatically. If you install just one solar panel in your home, you could greatly reduce your electricity bills.
The advances in technology
and the discovery of new renewable energy sources will continue to improve our lives in many ways and help us to fight global warming and the depletion of our natural resources. Wind power and solar power are two great ways to combat global warming and are readily available. Now, more than ever, people are realizing that fossil fuels and nuclear power are seriously damaging our environment, and switching to renewable energy is not only good for the environment but your wallet. Even if you do not choose to go completely green, investing in both technologies can help you make the necessary changes so that you can help fight the pollution and degradation of our natural resources.
