Recommended: Alternative source of energy
In recent decades, much debate has ensued about the vast amount of natural resources and ecological services society depletes. Moreover, the debate has evaluated how society depletes these natural resources at a faster rate than the environment can replenish. It also assesses how society can mitigate these environmental issues in order to preserve our natural resources for the prosperity of future generations. Research suggests that the natural resources we currently use, such as coal and petroleum, could be fully depleted within the next 25 and 100 years respectively (Byrd, 2012). Given that society has a tendency to over-consume natural resources, many economists have suggested that the use of alternative energy could alleviate the effects of overconsumption and the environment's ability to replenish. Therefore, this study evaluates the potential of solar energy (SE) on society and the environment by evaluating a cost-benefit analysis between solar energy technology (SET) and conventional energy resources.
Electricity and The Call for Solar Technology:
Research on conventional energy resources has shown that the demand of electricity has drastically increased in recent decades, and will continue to increase in the future (Zweibel, 2010). Moreover, by evaluating business as usual models, where the annual growth rate of demand for electricity ranges from 2% and 3.2%, research has suggested that annual world demand for electricity will soar from around 20 trillion kWh (kilowatts) in 2010 to 60 trillion kWh in 2050 and 200 trillion kWh by 2100. Additionally, the average growth rate of renewable resources has only increased about 1.6% per annum, in comparison to the 4% annual growth rate of conventional energy resources. (Lloyd & F...

Despite generating electricity with fossil fuels for years and years there is a much better way that does not harm the environment. Using Solar panels does not produce any carbon dioxide unlike fossil fuels that “produces huge volumes of carbon dioxide, which is a gas that influences the global climate” (“Solar Power Vs. Fossil Fuels”). Having the choice to get power in a new way that saves the environment, home owners should not have to think twice about trying solar. In fact if home owners collect some amount of watts per hour on Monday, that will not reduce the amount of solar energy a home owner can collect on Wednesday or any other day that week. They can always keep collecting the power. No matter what people may argue about how much coal, natural gas and petroleum remains buried in the Earth, those fossil fuels will run out far earlier than the life of the sun ("Solar Power Vs. Fossil Fuels"). Home owners should invest in solar energy because solar systems have very dependable technology with little maintenance, they offer financial savings and they are better for the environment.
Instilling this new way of energy usage into off-grid communities will inevitably increase the state of living for those in cities and other well-populated areas. The change to renewable energy sources could drastically lower the pollutants currently being dispersed into the atmosphere by coal mines and other harmful power options, increasing the supply of renewable energy would allow us to replace carbon-intensive energy sources and significantly reduce U.S. global warming emissions. a 25 percent by 2025 national renewable electricity standard would lower power plant CO2 emissions 277 million metric tons annually by 2025—the equivalent of the annual output from 70 typical (600 MW) new coal plants (“Benefits of Renewable Energy Use”). Electricity production accounts for more than one-third of U.S. global warming emissions, with the majority generated by coal-fired power plants.

The sun has been a major aspect of life since the beginning of time. People used many other forms of energy before electricity was discovered. There has been a debate over energy resources for years. Many people are worried about what current energy resources may be doing to the environment. Oil spills and nuclear power plant mishaps have only been a few accidents that have had a big impact on the environment and the people who inhabit it. There are plenty of energy sources that do not harm the environment and are still able to get the job done. Solar energy is one energy alternative that will insure the betterment of the country and, at the same time, protect the natural environment.
How solar energy, a non-fossil energy resource, non CO2 producing technology, can disrupt man’s addiction to oil gas and coal and reduce CO2 emissions.
The future of the United States solar energy industry will be shaped not only by economic growth, but also by the rate of declining oil resources and the global realization of the consequences of human induced climate change. Political responses to this realization in the United States include; new policies, legislature, and tax incentives to both businesses and private households to promote growth and investment in the solar power industry.
Energy is the basic necessity of daily life. Nowadays, dependence on fossil fuels for energy needs becoming lower in numerous countries due to the potential of renewable energy to supply sustainable energy to the huge populations in many developing countries who are short of clean and continues energy. Generally, renewable energy can be defined as energy that is derived from natural resources which are constantly replenished and theoretically inexhaustible. Fossil fuels on the other hand can be described as energy that cannot be renewed and will eventually diminish. Thus, in many developing countries renewable energy is the alternative energy to replace non-renewable energy or commonly known as fossil fuels. In addition, according to Sorensen (2004), there is a greater demand for renewable energy sources nowadays due to the uncertainty of fuel price rise in living expenses. Commonly, there are many types of renewable energy available in our world such as wind power, biomass energy, solar energy, hydroelectric power and geothermal energy. However, the main three example of renewable energy are hydroelectric power, solar and biomass energy (Refer to Figure 1 in Appendix 1).
Our challenge topic is to make solar energy more economical. By doing so we need to make solar energy more efficient. Although the sun provides a lot of energy, we are currently only able to efficiently convert 10 to 20 percent of it into electricity. This topic is very challenging because costs of electricity that is provided by solar energy is around 3 to 6 times more expensive than the current prices of electricity. Storage is another problem that we face because it 's rather hard to storage solar energy, unlike storing other sources of energy like heat. This challenge exists because fossil fuel produces toxic waste such as carbon dioxide which pollutes the climate we live in. Fossil fuel which is our main source of energy will one day run out and we will need solar energy to replace it. Solar energy produces no waste, and with no harmful leftover. “Solar energy is radiant
Preview: Today I will discuss the potential that solar power has to become this country’s main supply of energy and the latest research that can make solar power more efficient and cost effective. I will also present the environmental benefits that come with using solar power over other and more harmful forms of energy.
According to the Union of Concerned Scientists, “Renewable energy — wind, solar, geothermal, hydroelectric, and biomass — provides substantial benefits for our climate, our health, and our economy.” One major benefit is that there would be little to no global warming emissions. Currently, electricity production accounts for about one-third of the emissions put off by the United States, mostly due to coal-fired plants. Renewable energy sources would produce little to no emissions. “According to data aggregated by the International Panel on Climate Change, life-cycle global warming emissions associated with renewable energy—including manufacturing, installation, operation and maintenance, and dismantling and decommissioning—are minimal” When comparing renewable sources to natural gas, which emits between 0.6 and 2 pounds of carbon dioxide equivalent per kilowatt-hour (CO2E/kWh), renewable sources such as wind, solar and hydro-electrical power emit somewhere between .07 and .5 (CO2E/kWh). It is obvious that renewable energy is the way to go in order to solve the energy production problem. (Benefits of Renewable Energy
I am certain that all have heard of the terms green house gases, fossil fuels, and global warming. Have you ever questioned what will happen if nothing is done about the environmental problems facing the world today? What if I answer you that, we can merely use the power from the sun to power up our entire planet without the use of harmful energy sources, which affect our atmosphere? The power from the sun is what we call solar power. Solar power is the energy that comes from the sun as light and heat energy, and then it is later converted into electrical energy through solar panels (Nelson, 2008). This kind of power is completely free, right? Why should we put a lot of expense on other sources of energy, when there is a complete free and healthy power? It is evident that solar energy is a healthy source of energy, which will help stop global warming all together, but it is economically efficient to switch everything to solar energy. Solar energy is capable of becoming the world's future power supply because, it is renewable, eco-friendly, and extremely efficient when strategically placed.
The Earth captures around 342 W/m2 of energy from the sun. This energy is in the form of solar radiation, which the atmosphere reflects about 77 W/m2 and will absorb around 68 W/m2 of solar radiation annually. Therefore, the Earth’s surface is receiving, on average, about 197 W/m2 of solar radiation annually. This amount of energy received is roughly more than 10,000 times the amount of all energy humans consume per year. This energy can be used to produce electricity or heat. This energy source is not being used to it’s potential considering how much effort would come into effect to store and transport this energy.
Regarding solar power, Mistry claims that although the solar power does not generate pollution, it has a lot of costs. Building solar panels with photovoltaic equipment has high costs. For instance, a photovoltaic system for a home can cost around $35,000 (Kumar, 2012). However, if our goal for the future is to create a healthy environment, switching 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.
The world that we live into today affords us the expectation that the flip a switch will turn the lights on. As populations increase and developing nations undergo dramatic economic growth, this energy demand will only continue to grow. The International Energy Agency (IEA) believes that “the world’s energy needs could be 50% higher in 2030 than they are today” (ElBaradei). Given this projected growth, it is necessary for world leaders must take action to secure the energy supply. Meaning that world leaders need to start seriously considering an alternative to non-renewable energy sources. “In 2012, the United States generated about 4,054 billion kilowatt-hours of electricity. About 68% of the electricity generated was from fossil fuel (coal, natural gas, and petroleum), with 37% attributed from coal” (U.S. Energy Information Administration). The fossil fuels that are used to supply over half of our country’s energy are in finite supply and are increasing in price to astronomical heights.
