The Effects Of Renewable Energy On The Earth s Climate

Over the years, the unequivocal increase in the Earth’s climate has been an issue concerning environmentalists and other scientists. With overwhelming evidence pointing to environmentally damaging human behavior as the culprit for the Earth’s rising temperature, a search for cleaner and renewable energy sources creates a vastly growing alternative energy industry. One of the most widely used forms of renewable energy is hydroelectricity. Like the name implies, hydroelectricity refers to the generation of electricity through use of hydropower. In particular, the gravitational energy of falling, flowing, or spinning water can be transferred to electric energy through Newton’s Law of Conservation of Energy (i.e. energy cannot be created or destroyed, but can be transferred from one form to another).9 This renewable energy source has grown in popularity vastly over time since the industrial revolution, and now accounts for nearly 15 percent of the Earth’s t otal electricity generation.9 The benefits hydroelectricity speak for themselves; hydroelectricity yields no direct waste, has a relatively low costs and expenses, and releases considerably less carbon dioxide emissions than the burning of fossil fuels. However, some recent studies have suggested that the vast benefits of hydroelectricity do not outweigh the damaging effects on the surrounding ecosystem. Hydroelectric power has been used in its most basic form in ancient times to perform agricultural and other laborShow MoreRelatedGreenhouse Gas Emissions And Climate Change967 Words   |  4 PagesGreenhouse Gas Emissions Resulting in Climate Change The Sun is responsible for all of the energy that enters the Earth’s atmosphere. The Earth s energy is in balance when Earth emits the same amount of energy as it absorbs (Schneider, 1987). But today, the Earth is absorbing more energy than is what is being released due to increases in greenhouse gases in the Earth’s atmosphere (Herbert, 2007). Out of the total energy entering the Earth’s atmosphere, as seen in Figure 1, only 30% is being reflectedRead MoreFossil Fuels : An Essential Foundation1416 Words   |  6 Pagesthese prehistoric sources of energy have lately been identified to be a major source of an onset against the well-being of the Earth. Because of the adverse effects of fossil fuels, the effort placed into the solutions for prevention, and the obstacles that will hinder the implementation of the solutions, global climate change through the use of fossil fuels is an imperative fact that invokes the immediate action of governments around the world. To start, climate change requires immediate attentionRead MoreClimate Change1705 Words   |  7 PagesOutline: 1-Introduction for climate change †¢ Background information †¢ Definition of climate change 2-Body: A- The causes of climate change †¢ The causes of climate change †¢ Natural causes of climate change B- Effects of climate change †¢ Human effects on climate change †¢ Greenhouse gases effect †¢ Changing in the ecosystems.

The meaning of it seems to be not as easy as its name indicates which is merely a difference in climate. NASA (2011) reports, â€Å"Climate change, therefore, is a change in the typical or average weather of a region or city†¦ Climate change is also a change in Earth s overall climate. This could be a change in Earth s average temperature, for example.† Therefore, climate change in ourRead MoreBio Final Outline892 Words   |  4 PagesSentence: By using non-renewable resources mankind is putting a strain on the earth and causing global warming. 　 Paragraph: Do you know the difference between a non- renewable resource and a renewable resource? A non- renewable resource is a natural resource such as coal, gas, or oil that, once consumed, cannot be replaced. A renewable resource any natural resource (as wood or solar energy) that can be replenished naturally with the passage of time. By using non-renewable resources mankind is puttingRead MoreThe Effects Of Global Warming On The Earth Essay1733 Words   |  7 PagesSave the Earth The Earth is slowly dying and we can save it, however, it requires some initiative. Global warming, or climate change, is a very real problem that may soon wipe out the Earth’s resources. Some of which include necessary items such as natural foods and water. This problem doesn’t just happen in some third-world country no one has heard of. This is happening right in our own back yards. This problem has a very simple solution: conserve energy, cut down on Carbon Dioxide emissionsRead MoreThe Inexact Science of Climatology667 Words   |  3 Pagesthe ‘greenhouse effect’, and human activity has caused the accumulation of greenhouse gasses to increase across the world (McKibben Wilcoxen, 2002). The application of microeconomic principles can be used to address some of the fallout of the climate change caused by the greenhouse effect. In this paper we will take a look at three such measures and what their application can mean to the industry. The same way that there are various uncertain factors when accounting for climate change (clouds,Read MoreNew And Alternative Sources Of Energy1311 Words   |  6 Pages Today s society uses enormous amounts of energy. *The shadow of our presence on this planet is a result of generations upon generations of production and utilization of energy*. New and alternative sources of energy are being developed to replace the declining accessibility of coal and fossil fuels. Use of renewable energy is a key component in combatting the climate change that has become a major issue in the 21st century. Reducing our impact on the climate as a result of greenhouse gas emissionsRead MoreRenewable Sources Of Energy Effectively Replace Fossil Fuels Essay1614 Words   |  7 PagesAlternative energy Can renewable sources of energy effectively replace fossil fuels?

This smog has led the general population, political leaders, and scientists to ask the question, â€Å"What produces this haze and what are the impacts on our health and environment?† (Fischetti). The average amount of energy consumed per person has dramatically increased over the past several hundred years (Christensen, 482). The prevalence of fossil fuel use in our world is a primary
