Hence heat energy can be retrieved almost anywhere under the earth (Raven, et al. 2012). Similar to other renewable energy sources, geothermal energy has environmental and economic advantages compared to fossil fuels. Geothermal energy is captured using a geothermal power plant. These power plants are used to generate electricity from geothermal energy sources which are within the earth.
According to the Energy Information Administration (solar vs coal 2), 15 years ago, the electricity industry made a huge shift towards renewable sources of energy because of its cheap availability and increasing popularity. The author also compared the coal and the solar energy of at this time as a new electricity generation. Both solar and coal produce energy, but solar energy is more beneficial because of its efficiency, construction cost, and is environmentally safe and healthy. Everyone needs energy for various purposes. The first thing to consider while choosing the energy for us is its efficiency.
These primary sources are converted to electricity, a secondary energy source, which flows through power lines and other transmission infrastructure to your home and business. 7 Types of Renewable Energy Sources 1. Solar Energy One of the first renewable sources of energy is sunlight. It is the reason why life on the planet Earth has flourished and is the one truly renewable source of energy. About 70% of sunlight gets reflected back into the space and we have only 30% of sunlight to meet up our energy demands.
The greatest benefits of wind power are relative as each article and image may find a single item most improved by wind power as people all have different opinions. The graph emphasized the safety of wind compared to coal. Maehlum agrees as turbines create neither pollution nor leaves any waste that harms the environment. “Wind Energy Basics” adds once the wind turbines are finished, they become low in cost while other sources continue to need funds. Power plants perpetually require funding and constant care in hope to diminish harm that may be avoided such as a nuclear meltdown or a sudden release of gases which damage the atmosphere.
“Every second, our sun produces enough energy to sustain Earth’s need for 500,000 years”(Energy Efficient Residential Solar Power). The sun is something that we see everyday, but people choose not to use its energy to produce power in their house. Solar energy is beneficial to society by not polluting the Earth and producing more jobs in the solar industry. Solar energy is a renewable resource that can be used to power homes in efficient ways and doesn’t produce greenhouse gases. Fossil fuels release an abundant amount of carbon dioxide into the atmosphere when being burned to produce energy.
Solar energy is defines as energy in the form of electromagnetic radiation generated by the sun through thermonuclear fusion that converts hydrogen to helium (Brown, 1988). The three main benefits of solar energy are ease of access, environment friendly and cost effective
The advantages of using wind energy is that it is renewable, you can us use as much as you want and it’s not going to run out. Unlike any usual power plant, wind farms release no pollutants. In 1990 California’s wind power plants emitted more than 2.5 billion pounds of carbon dioxide, and 15 million pounds of other pollutants that could have been produced. It would take millions and millions of trees to provide the same air quality.Although a disadvantage of wind energy is that the wind doesn’t always blow in certain areas so the amount of wind turbines may be limited due to the absece of
Nuclear would play a large role in reducing the greenhouse emissions and solve the climate problem in order to assure that there would not be an escalation in global warming (Knapp et al, 2010). Some suggest that renewable energy sources would be able to achieve the same ends as nuclear power in providing a clean energy source to reduce emissions for the environment; however, they would be unable to meet the increasing energy demands. Compared with nuclear energy, the renewable sources are unable to replicate the type of power generation that is needed to power the grids making nuclear energy a better choice. Loudermilk (2011), a research associate for the Institute for National Strategic Studies, warns that “On the global level, without nuclear power, carbon dioxide emissions
Energy bills would be greatly reduced, and they would have the satisfaction of knowing they are making a difference. Even if solar panel cost and their availability of space looks like a minor issue now, they will become cheaper, more energy efficient, and maybe even smaller to save room for more in the near future. Solar energy is gaining attention all over, as is an even lesser
Solar energy is said to be clean, renewable and free from carbon footprint. This is substantiated more in Article 4 where I speak about the pros and the cons of using solar power. South Africa receives a huge amount of sunlight daily it would to our advantage indeed to harness the energy from the sun and then convert it to electricity without introducing the use of fossil fuels this is why one can consider Solar power as being “green”. We shouldn’t only look at big businesses but if they can switch to Solar power that will reduce South Africa’s footprint tremendously this is also substantiated more in article 5 that is titled “Why Big Business”. They are many pros in using solar power although one might only want to look at them but for a reliable research one must also state the disadvantages of using solar power.
