Renewable Energy Essay

Good Essays
Why do we need to rely on renewable sources? Most of the energy that we use today come from fossil fuels such as natural gas, coal, and oil. All of these resources are non-renewable, it can finish one day. In order to have a better world and a healthy environment for the future, people are trying to obtain energy from natural resources instead of non-renewable sources. In the lecture “Renewable energy resources” (2014), Mistry focuses on some advantages and disadvantages of renewable energy. There are different kind of resources that we can use in order to produce renewable energy. Solar power, wind power, hydroelectric power are just some of the kinds of renewable energy that might be the best options to obtain energy because they come from…show more content…
Although renewable energy can be expensive to build, it has less environmental damages in comparison to non-renewable energy. Besides the natural resources such as sun, wind, water and hydrogen, we also have geothermal power, and biofuels as renewable sources. First of all, solar energy is the energy produced when the sun heats the solar panel. Thus, when the sun heat the panels, it produces electricity. Solar power produces energy during the day and can storage energy for the night. Solar power does not pollute so much the environment. However, it has high maintenance cost, and it takes a large land space. Secondly, 15% of World electricity comes from wind. In order to have wind energy, it is important to have turbines to get the wind in order to produce electricity. Tall turbines produce more energy. The drawbacks of wind power are that it requires steady wind and its installations may interfere with TVs, cellphones, and other electrical devices. However, it is quickly built and there is no pollution nor noise produced. Third of all, the water falls in the dam can also generate electricity. For instance, 19% of world electricity comes from water. Regardless of the fact that hydroelectric power has low maintenance costs and does not pollute the environment, it can cause earthquakes, and destroy wild rivers. Only 0.3% of world energy…show more content…
Regarding to solar power, Mistry claims that although the solar power does not generate pollution, it has a lot of costs. To built solar panels with a photovoltaic equipment has high costs. For instance, a photovoltaic system just for a home can cost around $35,000 (Kumar, 2012). However, if our goal for the future is to get a healthy environment, switch fossil fuels for solar power might be the best choice to achieve that goal. According to Kumar (2012), Solar power is a clean and renewable energy so, it decreases the dependency on fossil fuel and also reduces the air pollution. When the sun heats the panel, it generates clean energy which does not pollute the environment. All in all, the costs of solar power might not be applicable when it is certainly the best way for having a clean
