Pro: Solar and Wind Energy Sources
I
Historical background
In 1767 Swiss scientist Horace de Saussure was credited for the first solar collector. After that in 1816, Robert sterling created a heat engine which was used for dish/sterling. The scientist Edmond Becquerel discovered photovoltaic cell, when he experimenting with electrolytic. He discovered that a solid material-selenium produced electricity currents when exposed to light. In 1870s august and his assistant Abel pilre constructed the first ever solar steam engine. Selenium photovoltaic cells are converted from light to electricity by 1 to 2 percent efficiency. The first commercial solar water heater was invented in 1891 by the inventor named Baltimore. Wind turbines were small until 1940s the largest wind turbine began operating in Vermont hilltop known as grandpa’s knob. The university of Delaware build “solar one” one of the first PV powered residence. After that Arco solar became the first produced more than 1 megawatt of PV in one year. Around 1982 worldwide PV production exceeds 9.3 megawatts. Then in 1986, the world’s largest thermal electricity facility began built in California’s Mojave Desert. Then NASA got in the action and installed 83 photovoltaic power systems on every continent except for Australia.

Opposing argument
There are some bad things about using solar and wind energy. One of them is that solar and wind farms cannot generate electricity when it is cloudy, dark or still days. Well there are some resolutions for that promblems.one is to have battery storage to store energy when those types of days come. Another is o only use that energy source where it is geographically area. Another problem is that fossil fuel energy is cheap and is abundant. Solar is more expensive but it will never be used up unlike fossil fuel that is not renewable source. Wind power has problems too like that the wind turbines blade kills 20,000 to 37,000 birds a year in the u.s. wind power is not as dangerous as nuclear power plants because people have reported that 35,000 radiation induced cancer deaths.`

Findings
Should we only rely on oil reserves or nuclear power? Or should we think about the environment and use renewable sources like solar and wind energy. Unlike nuclear and fossil oil, solar and wind are abundant and they are reliable resource to use. Solar and wind power are renewable resources that have been successfully used worldwide the last 200yrs. Solar power is clean, does not negatively impact the environment, Wind power is abundant and the other energy sources negatively impact the environment.
Solar power has been easy to use and safe for the environment.pv and solar thermal are two ways solar energy is converted to electricity .solar power is clean and does not involve no moving, has no toxic gases and does not impact the environment. Solar has been used directly for heating and lighting homes. Solar panels harvest more power...

Energy Resource: Coal and Solar Energy

2271 words - 10 pages Can you imagine not being able to plug your cell phone in to charge, or use the microwave, or turn on any lights? These would all not be possible without electricity. Electricity can be produced in many ways. Two ways are through coal and solar energy. The way these two energy sources are produced and the effects they have on the environment are very different but they are both used to produce electricity. Coal is one the fossil fuels in this

Energy Resource: Natural Gas and Solar Energy

1574 words - 7 pages My two topics that I will be talking about are Natural Gas and Solar Energy. Natural gas is a nonrenewable resource and pretty soon we are going to have to learn how to do without it. Solar energy will always be around. It’s not very major now but in a few years I’m sure it will be. Natural gas is a mixture of Hydrocarbon gases that form with a petroleum deposit. A hydrocarbon is a compound that’s mostly made up of Hydrogen and Carbon. Natural

The Pros and Cons of Wind Energy

1646 words - 7 pages Wind power is a form of solar energy. Wind is created by unequal heating and cooling of the earth from the solar energy. The energy from the sun heats up the earth causing warmer air to rise. As this occurs, cooler air rushes in to replace the warmer air creating wind. Wind energy can be generated into electricity producing natural power using wind turbines. Wind turbines convert the kinetic energy in the wind into mechanical power which can

Conversion Efficiency of Active Energy and Solar Energy

Solar Energy And The Energy Crisis

699 words - 3 pages Solar Energy and the Energy Crisis Abstract The energy crisis is a major problem in the United States. Solar energy can help alleviate this problem. Enough solar panels to fulfill the energy needs of the entire United States would take up 27,347 km2 and cost almost 17 trillion dollars. Therefore, although there is enough space for all those solar panels, the economic cost is far too great. However, solar power can be phased in gradually
