Renewable energy

Planetary Switch Just how “green” is going green? It turns out, renewable energy might not be as great as you think. According to, (At Issue: Renewable Energy) renewable energy is something our world needs at present time. Fossil Fuels will eventually run out and there needs to be a backup plan for an alternative energy source. Renewable energy is possible to achieve, but it is going to cost a lot of money. The big question is; is renewable energy worth the major cost? This paper will explore…

clean renewable energy that does cause pollution or would you want energy that is not renewable and causes a lot of pollution and makes harmful environments? I believe that Geothermal energy is better than fossil fuels because it cost less, environmentally friendly, and can be accessed anywhere in the United States, also can produce almost the same amount of energy as most coals mines can. Geothermal Energy plants cost less over time they can pay off their debt because the amount of energy it…

the Dam alone it produces on average 4 billion kilowatt-hours of hydroelectric energy (“Hoover Dam”). Hydropower is being looked at as an safe alternate source of energy. There have been several debates about the dependency of oil and the repercussions of it. Suggestions such as using coal and nuclear power have been looked at but there have been horrific examples of what nuclear and coal power can do. Hydroelectric energy is being seen as a really…

to position renewable energy in our system in such a way that it soon dominates the power grids across America, ceasing our addiction to fossil fuels. The policy option that will successfully enable this switch is feed-in tariffs. According to KEMA, Inc., an energy consultant that frequently prepares reports for governmental energy agencies, “a feed-in tariff is an offering of a fixed-price contract over a specified term with specified operating conditions to eligible renewable energy.”…

(McCarthy “Greenhouse Gas Emissions”). Most commonly, it is emitted by Americans driving cars. Even though driving cars and burning fossil fuels does pollute the environment, no renewable energy source comes close to generating the same amount of energy that fossil fuels do. Nevertheless, the burning and usage of these non-renewable fossil fuels can have long term devastating effects if not payed attention too. For example, with increasing levels of greenhouse gases being added daily, the…

In order to extract energy from ocean waves, one must first understand how waves are formed. Solar radiation from the sun is absorbed differently on the earth’s surface. The imbalanced heating of the earth’s surface causes the warm air to expand and rise, whereas the cool air sinks due to its higher density, thereby generating a pressure gradient. In order to return to an equilibrium state, the air from the high pressure zone has to replace the air in the low pressure zone. The movement of…

Wind energy should be used instead of fossil fuels. The demand for wind energy is increasing so the number of wind turbines needs to increase to keep up with the global demand. Wind energy costs are lower than the cost of fossil fuels. There are several reasons to choose wind energy over fossil fuels. There are many types of renewable energy sources, but wind energy is the energy resource of the future. The demand for wind energy is increasing, so this means that the number of wind turbines…

the use of renewable energy instead of using oil or fossil fuel that can destroy the environment and can also help support five hundred thousand peoples’ jobs instead of losing their job. For starter, construction worker has more work and payment by building wind turbines. Another benefit is the market of wind power is increasing from the support of the president and the government that has been making a huge investment in wind power. Wind power is the largest source of renewable energy in the…

An alternative energy sources are so important. Wind, solar, geothermal, and hydroelectric and biomass are needed and are alternative renewable energy that is beneficial for climate control, health benefits and the economy (Renewable Energy World. (1999). these technologies need to be explored to understand the benefits that can be argued by their use. This would prevent carbon dioxide and other gases from escaping into the air, which causes planet’s temperature to rise. The increasing the uses…

Renewable Ressources The Earth as we know it today is endangered. At the brink of a monumental shift in living conditions, caused by manmade global warming, mankind is scurrying towards averting this calamity that would forever change the Earth. Global warming is slowly progressing towards the point of no return, which will lead to mass extinction of fauna and flora all the while forcing humans to abandon coastal areas as the sea level rises. Having identified fossil fuels as the main catalyst…
