Solar Energy: Opportunities and Challenges
Fossil fuels have been people’s major source of energy since Britain’s industrial revolution. With regards to their potential exhaustion of and the related pollutions caused, there are rising concerns in developing and adopting to alternative energy source, which is more sustainable and environmental friendly in comparison with conventional fuels. Renewable energy is a solution to such problems. It is energy that generates from resources which can be naturally replenished on a human timescale such as sunlight, wind, rain, tides, waves and geothermal heat (Stover, 2011). Conventional fuels were substituted by renewable energy in four distinctive applications: electricity generation, water heating, motor-power and energy supply in rural area.
Solar energy, one of the major type of renewable energy, has been selected as the topic of this paper. The paper is started with the opportunities of solar energy by discussing its existing and potential applications, followed by advantages and disadvantages of the use of solar energy, and also the limitations of solar energy.
1. Solar Energy and its Opportunities
Solar energy is radiant heat and light from sun, though we are surrounded by sunlight in daytime, it cannot be directly …show more content…

Individual panel can generally converting just 10% to 18% of solar energy into electricity (wiseGEEK, 2014). The scale of formation depends on required amount of electricity, amount of sunlight that can be received, and other various factors. On top of the cost of the solar panels, the cost of installing the whole system greatly varies by location of system, required number of panels and auxiliary parts. By generally estimation, six years is the shortest time period to repaid the initial costs by savings from power generation in best situation, which means it may takes longer time under worse

    While it is proven that solar panels are tremendously helpful in terms of reducing the use of fossil fuels, it comes with a price. Solar panels are expensive; solar panels are expensive to make, install, and maintain. While solar panels do eventually break even in terms of cost, this takes years of operation to bring a profit. Studies have also shown that solar arrays have the potential to cause changes in temperature and precipitation by altering the amount of solar radiation absorbed by the earth (Harvey, 2015). The biggest problem with solar panels is the cost.

    A solar panel can be used for many things, but the biggest thing is used for capturing the sun's energy in order to make it useful provide energy to the house, buildings even be sold back to the city or town you live in etc.. It works by collecting the sunlight throughout the day, then converts into energy that's usable, then the electricity travels to the net meter then the energy is used for anything. When having the solar panel on a roof you can use it for personal use or even sell it back to the electrical company and they’ll pay you. There are about 73,000 terawatts of energy shining down that's 10,000 times then what we use on daily bases. Perks of having solar panels it's a tax 30% tax write off, doesn’t need any fuel combustion, Securing your energy and not depending on National

    Not only having solar panels will reduce the electrical bill, but solar energy can be stored. This makes sure that the school will have sufficient energy to run the school. Also, since the solar energy can be stored, it won’t affect it when the weather is cloudy and not sunny. This is a big benefit of having solar panels they will last longer, they are cheaper, and they

Background and Audience Relevance: As stated by C. Naff in his 2007 book Feeling the Future Solar power the development of the Solar Panels began during the mid-1800, this was during the Industrial Revolution to be able to heat up water and also steam for the machinery. In the year of 1839 French Scientist Alexandre Edmund Becquerel discovered the Photovoltaic process. Years later in 1941, an American Engineer Russell Ohl invented the solar cell.

    The targets in goal 13 vary on their ability to perform measurably. To begin, Target 13.1 can be measured by comparing how well a country deals with one natural disaster vs. another. However, other factors must be considered such as the intensity of the disaster, the resources available, etc. Target 13.2 is easily measurable, by comparing national policies and seeing whether climate change measures really have been implemented. Target 13.3 however, is arguably measurable as different strategies to raise awareness, improve education and human capacity are all subjective measures.

    Global climate change is a very serious problem that we must pay close attention to. The main reason that causes climate change is that there are too many carbon dioxide in the atmosphere. If the temperature keeps getting higher and higher, there will be many problems that can cause great damage to us and the environment. If we don’t replace fossil fuels with other clean energy, our Co2 level will be as many as the time of the dinosaurs and we don’t know what will our lives be if this really happened. The best way to solve this is by using solar energy.

    I believe fossil fuels have overstayed their welcome and now is the time to act. The world needs to be weaned off fossil fuels as their main energy source and as the President of the United States of America, you, President Obama need to put in more effort into the research and development of renewable energy to protect future generations. Bring us up to date NASA’s data has shown earth’s climate has always been changing and the last ice age ended around 7,000 years ago bringing us into our current climate era now. This was also around the time humans came into existence and within the past 1,300 the earth has been warming at a significant rate that has not been seen before. There is good reason to believe these changes are man-made.

    Next, you can determine how many solar panels you need to meet that need. SunPower breaks down the math so you can plug in your own specific company numbers, but an average amount comes out to about 70 solar panels to run a business that consumes 70 kWh per day. To find a rough estimate of your costs, you can start with the assumption that you will need one solar panel per kWH consumed per day.

    Scientists have found that renewable energy is a path towards the future for a clean and safe environment. Throughout all the studies and findings, there is a continuing fret whether people should be able to use a traditional way of energy or renewable energy, solar power. Solar energy is seen to be effective since there has progressively been more places that are benefiting from solar usage; however there are also some who disagree. Solar energy sources are derived from natural sources and is implicated throughout our daily lives. From the lights in the streets to the computers we use at home.

    wind energy and solar energy are both renewable types of energy they create no pollution and are fully sustainable as they are both powered by natural sources and if there is no wind one day the solar panels can generate energy and if it 's cloudy another day the windmills can generate energy also the energy created during the summer can be sold to the grid for extra capital that can be used for field trips, renovations, etc. Geothermal heating systems are rated the most efficient and eco-friendly heating systems. The system works using buried coils that contain a liquid, typically a mix of water and antifreeze. The liquid is warmed to the same temperature as the earth and then runs through to the home where a compressor extracts the heat but not only that geothermal heating requires no fossil fuels so it is very eco-friendly LED lighting is an efficient and eco friendly lighting alternative because they waste much less energy in converting to light compare to incandescent lights which waste 90% of the energy to convert to heat not only that LED lights last up to 15-25 times longer that traditional light bulbs this makes LED a much better source of lights than others because it wastes less energy and it is more efficient at doing its job this is so much better for the environment because it uses less energy that other lighting sources
