Essay On Advantages Of Solar Energy

Amazing Essays
1. INTRODUCTION:
The main focus of this assignment is to discuss or highlight why South Africa has embraced wind and solar as alternative energy sources. Wind and solar are the evolving renewable sources of energy. Renewable energy is generally defined as energy that is collected from resources which are naturally refilled on a human timescale, such as sunlight, wind.
Solar energy is energy derived from the sun in the form of solar emission. And wind power is a form of renewable energy created through the transformation of wind into electricity through the use of wind turbines.

2. BRIEF HISTORICAL BACKGROUND
South Africa is currently benefiting from clean electricity which is produced by several renewable energy technologies, which includes

You only spend during the initial setup costs. There might be a need to add a solar panel later on but won’t need to install a brand-new system. There are definitely no additional costs related with having a solar energy system in your home or business.
3.1.2. DISADVANTAGES OF SOLAR ENERGY IN SA
There aren’t too many disadvantages of solar power but there is one major one and it’s the fact that the sun doesn’t shine around the clock. Also, if you live on a property that has a lot of trees, this may block the sunlight. Once the sun goes down for the night, the solar panels stop collecting energy electricity. This means you’ll have to get it from somewhere else after this point.
• Where Your Solar Panels are Located
Disadvantages of solar energy in SA are where you place your solar panels. This will determine how much electricity you get. If installed in an area that doesn’t get much sunlight, you will still get some energy but you won’t be able to get the full benefits. However, during cloudy days, there will be solar energy but you’ll get significantly more in a brighter environment. Installation of more panels will be required in areas that have least sunlight or installation of a lower number of panels in brightly sunlit

DISADVANTAGES OF WIND ENERGY IN SA
 The major disadvantage of wind power is down to the winds unreliability factor. In most areas, the winds strength is too low to support a wind turbine or wind farm, and this is where the use of solar power could be great alternatives.
 Wind turbines generally produce less electricity than the average fossil fueled power station, requires multiple wind turbines to be built in order to make an impact.
 Wind turbine construction can be very expensive and costly to surrounding wildlife during the build process.
 The noise pollution from commercial wind turbines is sometimes similar to a small jet engine. This is fine if you live miles away, where you will hardly notice the noise, but what if you live within a few hundred meters of a turbine? This is a major disadvantage.

4. WIND ENERGY: IS IT AN EFFECTIVE SOLUTION FOR SA?
SA is blessed with an excellent wind resource, a fact now proven by some of the lowest wind energy tariffs in the world. The perception that fossil fuels are cheap and renewables are expensive is grossly out of date, using modern turbine technology we are able to harness wind energy extremely efficiently and economically. South African wind farms produce energy at lower rates than any other form of new build generation. It is likely that the price of wind energy will continue to decline, driven primarily by technical advancements and mass production, whilst at the same time the price for fossil-fueled energy will

    Wind energy generates electricity at the source making the cost fixed so prices would be more stable. Wind energy is also the lowest priced form of renewable energy costing only four to six cents per kilowatt-hour. Coal power has been found to cost between 9.5 and 27 cents per kilowatt-hour. Solar energy costs 12 to 30 cents per kilowatt-hour. It is clear wind energy is the most cost effective form of…

    To start with, it does not require any fuels in operation. Besides, it is not only cleaner than fossil fuel but also solar energy in that absolutely no pollutants are produced. Moreover, it is far less risky than nuclear energy. Nevertheless, someone may argue that it is again not reliable as the direction and intensity of wind are varying continuously. Furthermore, it will cause noise pollution and affect both the natural scenery and ecosystem.…

    The document “The energy story” states, “the solar cells and solar panels that are needed to harness solar energy tend to be very expensive”. This is showing that the cost of producing solar energy in the night could not cost efficient. Although this may be true solar energy saves electricity so the money being used for the electricity bill could now be used to pay for the solar panels at different weather conditions. The article “Solarcity” states, “When you begin to generate your own solar power, your electricity bill can drop significantly.”This helps fix the money situation because if you are creating the electricity you will not need to pay an electricity bill which is means you no longer have to pay money on the electricity bill. Using the money you were going to use on electricity spend it on the batteries to save solar energy for the night.…

    I think solar energy would be the most effective energy for the United States to develop. The energy cost has dropped because the technology improved. Although some still argue that solar energy is costly, it is beneficial to the environment because it is efficient, it will not give off harmful gases, and it is easily accessible. Solar energy is powered by sunlight, which converts it into solar heating and electricity. There are two types of solar heating systems, active and passive power; solar energy uses this to make electricity.…

    They have many similarities and differences, but solar power is is still a better source. Both Nuclear and Solar are power sources for humans, but solar power is more convenient that nuclear. There is a cost to build both nuclear power plants and solar power farms, but solar power plants cost a lot more. However, the cost of the fuel for nuclear power (uranium) is expensive while the cost of the fuel for solar power is free. Both solar power and nuclear…

    Cost, decreases in sales by electric monopolies, and mismanagement of funds do not out-way the benefits in using solar sources. The potential good from solar production is becoming easier and less expensive to make a reality. Continuing to incentivize minimum standards in Fort Collins will push the local community to invest in solar energy. The job market for skilled labor in the solar energy sector would increase allowing locals to engage in jobs they qualify for. Cost inefficiencies would decrease with a push on solar energy over time as well.…

    Batteries store solar power. Charge up the batteries on the sunny days and use that stored energy when the sun is hard to find. Many of the urban folks that are living without the grid, cloudy days and batteries get the job done. Solar energy is reduced when the sun is behind a cloud or on the other side of the world. It is low efficiency.…
