Their design uses a new cell structure containing four solar sub cells to become 44.7% efficient. It’s only 0.7% more efficient than the previous world record, but “it brings the solar industry one step closer to achieving 50% efficiency”(Valentine, Katie). Solar panels are panels that generate electricity when exposed to radiation from the sun. Solar panels use silicon, which emits an electrical current when in contact with light, to generate electricity. The radiation provides photons, or units of electromagnetic radiation, to the silicon to generate electricity.
The topic of implementing solar energy as the country's primary energy contributor has been one of much controversy; however, making this transition could promise a world of incredibly cheap power for an eternity. The following information will detail major discussion points in solar power that have significant impact on not just the industry but the way that ordinary Americans live their lives. The material has been organized into the following headings: current and projected capabilities, environmental impacts, cost, and solar roadways. Current and Projected Capabilities The total world energy demand is roughly 400 quadrillion British Thermal Units (BTU). One BTU is measured by the energy and heat generated by a match.
According to Eco Info in 2009, at the rate we are using fossil fuels at; we have an estimate of 46 years of oil, 63 years of natural gas and 119 years of coal. However if every Canadian home and every home across the world had solar panels they wouldn’t need to use fossil fuels to power their homes. Everyday solar panel technology is becoming much more efficient. “Every minute the sun bathes the Earth in as much energy as the world consumes in an entire year.” — (US Department of Energy web site, 2010). Now by harnessing this amount of energy the worldwide energy crisis will be solved.
Significance: The United States must face the fact that the world is running out of oil and with today’s rising oil prices, economic and political instability in regions where the United States gets the majority of its oil, this country must begin looking into alternative means of energy to replace oil and end our dependence on foreign powers. 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. Body: I. With the world’s supply of oil running dry the Unites States must begin looking into new sources of energy, and the most promising is solar power.
The two major problems from burning fossil fuels are global warming and decreasing oil supplies. However, Joel notes that there is a difference between this pending pandemic and the pandemics previously mentioned. This pandemic can be prevented. Solar energy is a nondepletable resource that can help us avoid furthering global warming and decrease our continued dependence on oil. Solar energy is, in the most rudimentary terms, energy from the sun.
and “fossil fuels are the primary source of about 375 billion tons of carbon that has been released into the atmosphere since the industrial era began in 1750” (Gerken). There is a desperate need for an alternative, more sustainable form of energy to replace the fossil fuels. Envision Solar, the world’s leader in solar energy, has developed their new Solar Trees to make solar energy more efficient and more affordable in an attempt to solve the current energy crisis. Envision Solar has teamed up with General Motors to develop their new solar trees and revolutionize the world of sustainable energy. The Solar Trees come in two different sizes, the Array is larger and can charge up to six cars at a time.
It seems like everything we use involves electricity. Our lives revolve around electricity and without it our world would be in a hullabaloo. As our days go on our electricity output increases and our Fossil Fuel storage decrease. “We can thank Fossil Fuels for providing over 80% of our energy we use around the world.” (CNN Wire) As we look ahead to our future, we have to find another source to get our energy. Renewable energy comes into play because according to several scientists, easily retracted fossil fuels will be used up during the 21st century.
As the population rises, the demand for energy increases as well. Americans expect the convenience of electrical power to be there when they need it and their economy depends on it, but a lack of power might soon be a reality. A large amount of electricity in the United States is produced by burning fossil fuels. The national government, as well as individual states, are on a quest for less pollution, but with the energy demand so high it seems lower carbon emissions are impossible. Despite claims that the aging electrical grid is to blame for energy shortages, fossil fuel power generation plants simply cannot keep up with demand.
