Energy Options for the New Millennium Essay

explains, “A solar panel works by allowing photons, or particles of light, to knock electrons free

Relevance Statement: Electricity is the heart of our current civilization. Without electricity we would regress into a feudal like stage which will slow down our evolution as a society

The main problem in the electric area of energy is that no one wants to use energy saving items until it is too late. The

The greatest energy that can be produced by the sun is electricity. Photovoltaics, or solar cells, capture the sun and convert it into electricity. Solar cells were discovered by the Europeans back in the 1870’s when they used selenium to develop the telegraph. They found that when light hits selenium it would produce and electrical current. Soon enough there were many scientists and engineers working on photovoltaic systems. Silicon and Selenium proved to be the two best elements to conduct electricity when light hits them. Photovoltaic systems (PV cell) work by converting the suns light into electricity. A semi conducting material absorbs the sunlight, that energy knocks electrons loose from their atoms, this allows the electrons to flow through the material to produce electricity. The further development of solar cells can be attributed to the satellite industry. Solar cells were expensive and there was no use for them until satellites came. Because it is impractical to tether satellites it became important to develop solar energy at any cost that would power these satellites. This created a sustainable market for solar power, the first of its kind.

If Americans didn't have energy then we wouldn't have cars we wouldn't have stores we wouldn't have really anything. The reason is because most things that we have or use now days use energy or something like that.Then no businesses would be making money and no one would have anything so that's one reason why we Americans need energy.

The coal industry in the United States has been a substantial job industry in states such as Wyoming, Kentucky, and Ohio providing up to over 76,000 mining careers in 2014 that area essential for the areas surrounding the mines but employment number is less than that of Arby’s, the fast food chain (Ingraham 2017). This size of the career poll brings into question what direction would be most beneficial for the United States in terms of our energy industries and where we should focus our efforts in terms of resources and time. The employment in the coal industry decreases exponentially with time due to the modern technology used to mine coal and decreasing demand. Additionally, coal mining has become

When we flip a light switch, or plug our laptop or cell phone charger into the wall, we expect that electricity will flow to illuminate the room or to power up the device at the other end of the cord. But what if the power companies weren’t able to generate enough electricity to make these actions possible? As the United States’ population increases and continues to undergo economic growth, this demand for energy 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” [1]. And while Americans only make up about 5% of the world’s population, we consume more than 20% of the world’s energy supply [2].

The existing green energy sources are solar energy, wind energy (harvested using wind turbines), geothermal energy (harvesting energy trapped in the earth), biogas (natural gas beneath the earth surface) and biomass (energy from biological material) apart from the hitherto mentioned hydroelectric source (EPA, 2012).

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

Every day, many fossil fuel consuming contraptions spew out gases that pollute the environment. However, when the fuel supplies for these devices run out, they will grind to a halt. To prevent this, the United States needs to find an alternative to unstable and polluting energy sources before it’s too late (Rouge). It also needs to advance in technological status in order to stay above advancing third-world countries, and retain its current level of hegemony (Glaser). Space Based Solar Power Satellites, which are satellites that collect the sun’s energy and beam it down to the Earth, solve for all these concerns (Rouge). Thus, the United States Federal Government should provide grants for research, development, and implementation of Space

Unlike gasoline or diesel, biofuels release little pollution. It can also be used to produce electricity by heating water using biofuels and using the steam produced to rotate a turbine. Another method is to allow the biofuel to decay and produce methane. Methane is commonly used as fuel for car, heating, cooking, and producing electricity.

The availability of an abundant amount of energy in the modern times has brought about higher industrial production, improved communication and transportation facilities and better management of the basic necessities. Development has never been as accessible to a broad range of people belonging to all social classes. The present-day society is so reliant upon the utilization of energy, most specifically electrical energy, that it has become a part of the people’s daily living. The actual magnitude that energy had input in the society is innumerable. The increased cost and consumption and the depletion of environmental resources are some of the reasons why energy production is constantly being enhanced over the long run (Discovery Education, n.d.). The constant improvements in power production have always aimed for the same goal: making power a better choice for efficient generation.

Solar energy may define as the energy received by the earth from the sun. This solar energy is in the form of solar radiation. With the help of solar cells, solar radiation can convert into electricity. Sun is a highly powerful energy source, humans and natures are directly depending on the sun. For example in hydro-electricity the solar energy needed for the evaporation of water after that it returns to earth as rain and provides water in dams. In biomass, the solar energy used that process. Solar cells directly converted solar radiation into electricity, during the process time there is no noise or pollution are there. These cells made with some semiconducting materials. If use solar cells in our home it will help to reduce the greenhouse gas emission, minimise the percentage of carbon dioxide in our atmosphere and mainly reduce the necessity of fossil fuels and natural gas use to produce electricity. According to the Ben Sorensen, solar energy is one of a good source of substitute energy, for the reason that it is renewable, economical and does not pollute our environment. Thus, this essay will be divided into three parts. Firstly, we will talk about fossil fuels and its demerits. Secondly, we will look at the issues and implications of solar energy. Finally, we will focus on the advantageous and disadvantageous of solar energy respectively.

Abstract: The current energy situation with fossil fuels as the main source of the world’s energy has two main flaws: fossil fuels contribute to global warming via the greenhouse effect and they are limited in the quantity that remains. Solar power solves both of these problems and can be captured by utilizing photovoltaic cells. However, photovoltaic cells have their own drawbacks due to their high costs of installation and maintenance.
