The Fundamental Time For Clean Renewable Energy Essay

The time has come, we’re running out of fossil fuels and we need an alternative. That is where renewable energy comes in; The best part about it is that it is renewable so it will always be available to us, and we can acquire this energy through solar, water, and wind power. There is a lot of controversy as to whether we should rely on renewable energy, because some say it is not cost effective. However renewable energy can pay for itself, is available nearly everywhere through various methods of obtaining it, provides numerous amount of jobs and economical benefits, and it will not harm our environment.

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.

Renewable energy is on the increase, however the rate in which this increase is taking place is too slow. This leads to our country not being very sustainable. Before we begin to talk about the roadmap, it is important that we must understand the definition of sustainability. Sustainability is conserving an ecological balance by avoiding depletion of natural resources . In terms of energy this can be achieved by increasing our use of renewable energy. Renewable energy is when energy is sourced from natural and alternative energy such as wind and solar .

Solar energy begins with the sun. Solar panels, also known as photovoltaics, are used to convert light from the sun, which is composed of particles of energy called "photons", into electricity that can be used to power electrical loads. Light from the sun is a renewable energy resource that provides clean energy, produced by solar panels.

Solar energy is the largest energy resource available on earth. Not to mention concern about climate change have made this resource prevalent to individuals looking to lower their carbon footprint. Installing solar panels can decrease a household’s carbon footprint by an average of 35,180 pounds of carbon dioxide per year (Tusher, Christine, 2014). Solar panels got their start in the 1950s. They are what produce solar electricity by using photovoltaic (PV) cells, meaning they are batteries that harness sunlight, transform it into energy, then send the energy to an inverter, which in turn converts the energy into electricity. A well-known example of an object that uses solar panels to power itself is a solar-powered calculator. One advantage

Solar is quickly becoming a popular project to take on. Not only does it help save the environment, but it can also help save money for businesses and homes that elect to make the switch to solar. However, completing a solar project is expensive and it is important to look for ways to promote efficiency of the install and of the system itself.

The sun is the source of all life on Earth. In just one hour the sunlight hitting the earth’s surface provides enough energy to power the global economy for a full year (Brown, 2015). The sun will continue to burn for billions of years, making it an unquestionably reliable source for renewable energy. Modern-day photovoltaic (PV) solar cells rely on the photoelectric effect, a phenomenon where light is used to free electrons from a solid surface - usually silicon - to create electricity. PV panels are typically installed on homes and buildings, or in ground arrangements, sometimes called solar farms.

Julio Cano-Vargas Comm 150-29 Prof. Parente 10/24/13 1) Introduction a) Attention Getter: Who here wants to help the environment? Who here loves to save money? Who here wants to get paid for doing nothing? Well you can do all that with solar panels, and I’ll tell you how.

Previously, we didn’t have to rely to much on energy, however times change causing a large consumption of energy. Solar panels may seem like a good idea due to its constant release of energy. On the contrary, in Source A, Michael Dhar states,” when a photon of sunlight knocks an electron free, the electric field will push that electron out of the silicon junction. A couple of other components of the cell turn these electrons into usable power” showing that at an optimal state, the sun will produce energy. These result often vary due to the amount of inconstant

In addition, solar energy operational costs are manageable. It is free from monthly charges compared to conventional sources of energy. Solar energy does not require raw materials such as oil and coal, and once the panels are built, there will be no monthly charges. In addition, the prices of fossil fuels are increasing day by day, and this means conventional energy will be very expensive. Solar energy will remain the most capable world’s future power supply because, it is cost effective once the plants are built, and there will be no transport costs like for conventional energy sources. Therefore, solar energy is cost-effective, and will help in future energy supply, as the maintenance cost is affordable, as long as they are installed properly, and are working efficiently ( Hans, 2012). Furthermore, with the improvement and advancement of technology, it will increase its efficiency, and cost of production thus, making it more cost effective and the world’s best

The term, “non-renewable energy,” is at its most basic form, means that the sources of energy will eventually one day run out and not replenish itself. Non-renewable energy comes in many forms. For example: coal, crude oil and natural gas. These sources are categorized as fossil fuels, meaning that they were formed in the past due to natural processes from dead organisms. Non-renewable energy has been proven to be very beneficial to the US, however, many people argue the negatives are not worth the benefits.

Clean sources of energy basically refer to those that do not encompass the burning of coal, petroleum or its products and the transformation of solid waste or nuclear division (Broyles 23). Therefore, renewable types of energy could be termed as clean sources of power because they are products of natural sources and do not emit hazardous by-products. Safe energy is not poisonous, is healthy, renewable, and sustainable and does not have devastating effects on the lives of the users, the

With a growing population around the world, the need for more energy increases as well. We are accustomed to using fossil fuels as our central source of energy for everyday exploiting. Fossil fuels are a natural matter that is found in the ground of the Earth that is formed in a previous time period millions of years ago and are nonrenewable. Fossil fuels are burned in order to fabricate energy. When nonrenewable resources have been used, they cannot restock themselves or be used again. Renewable energy is a supply of energy that can be used as many times necessary and does not necessitate a compound made from the Earth. There are several different types of fossil fuels and renewable energy that we use for energy sources today.

Reductions in the cost per peak watt can potentially be made to PV technology by increasing the net flux of solar energy to a given cell area. This can lead to reductions in PV prices independently of advances in PV cell technology126. This application of solar concentration saturates carrier traps inside the material, while raising the thermodynamic efficiency limit. The saturation of traps means charge carries are more efficiently transported, leading to improved overall cell efficiency127. Furthermore, under concentrated illumination, the open circuit voltage is found to increase with the incoming flux and thus the overall power efficiency can be increased128,129. Moreover, under solar concentration, light is focussed onto a smaller
