Solar Energy Pros and Cons - 1990 Words

Energy is defined in physics as the capacity to make things move; it is widely used in today people’s residences, a variety of industries and technology fields. Most of the energy we use now comes from fossil fuels coal, oil and natural gas, which are being consumed more rapidly than they are being replaced. That means eventually we will use up these fuels. That is why we as a society need to broaden our research to develop new forms of energy resources are for this happens. There are kinds of energy that can be replenished in short periods of time called renewable energy, these come from sources that are frequently being recycled and are consistently less polluting than energy that is produced from fossil fuels. There are five main†¦show more content†¦This is just example of oil but natural gas is another fossil fuel that is and has polluted the environment by seeping in to residence drinking water because of the exploratory extraction techniques companiesâ€⠄¢ use. Waste products from refineries not only affect the climate but the rest of the environment by seeping in to the land and ground water. These are some examples of how fossil fuels have a negative impact on our environment and how solar is viable renewable resources to counteract that but there are some negatives to solar energy cost is one. The major problem with solar energy is that it is very costly to buy the equipment although the price has plummeted since 1970 (Corcoran, 2003). At that time solar energy cells cost about $200 per watt, today, it is about $5.00 per watt (Corcoran, 2003). There are a number of innovations intended to change this disadvantage. For instance, SunPower of Sunnyvale in California has devised a way to make the solar energy cells cheaper (Business Wire. 2004). The new cells have a 20 percent efficiency which means they will generate about 33 percent more energy (Hogan, 2003). Part of the savings is in a new way to extract silicon. The co mpany SunPower estimates that average American families need 2000 to 3000 watts and the new solar cells can be met by using about 15 square meters of solar panels (Hogan, 2003). This is far less space than the regularShow MoreRelatedPros and Cons of Energy Sources1119 Words   |  5 Pages Pros and Cons for Oil Pros Cons - Readily available - Creates jobs for economy when required to drill and transport - Largest provider of electricity - The world has been using oil for the last 100 years - Not much new technology will be required to extract oil - Use of oil continually grows the U.S. economy - If certain regions would be allowed to drill oil in, then more oil could be extracted and the price could lower for gasoline - Production of oil rigs could lead to the development ofRead MoreSustainability And Construction Practices : Department Of Civil Engineering1256 Words   |  6 PagesScope of renewable energy 3 Types of renewable energy i.

The energy I would use to fuel my city is hydroelectric because its pros and cons outweigh the pros and cons of solar, coal, wind, and nuclear energy. The most efficient energy source for my city is hydroelectric energy. Hydroelectric energy is the most efficient for many reasons. Hydroelectric energy’s power fuel is water, which does not give off harmful chemicals or waste in the air or water; keeping ourRead MoreThe Pros And Cons Of Reusable And Non Reusable Energy Sources1727 Words   |  7 PagesThe Pros and Cons of Reusable Non Reusable Energy Sources There are many things that we rely on that are naturally provided by nature from the water that is used to replenish our systems to prevent dehydration, to the air that we breath down to some portions of food that we eat. One of those natural elements are used daily but are often not thought about outside of the scientific or political fields is energy.

As wind blows towards the blades of the turbine, the rotors spin around, capturing kinetic energy from the wind. The rotor blades are able to rotate around the hub (located at the front, middle of the turbine) allowing them to meet the wind at the best possible angle. Inside the nacelle (the main body of the turbine), the gearbox is able to convert the low-speed turningRead MoreSolar Energy Is The Conversion Of Power From The Sun1361 Words   |  6 Pages Research Paper – Solar Energy Blakely J. Phillips BGEN 440, Montana State University - Billingsâ€Æ' Introduction Solar energy is the conversion of power from the sun to usable electricity (Alternative Energy, 2014). The most common source of solar energy utilizes photovoltaic cells to convert sunlight into electricity (Alternative Energy, 2014). Photovoltaics use a semi-conductor to absorb the radiation from the sun, creating and emitting electrons, which are then harnessed and used as electricityRead MoreThe Future Of Alternative Energy1583 Words   |  7 PagesAlternative energy is defined as â€Å"energy generated in ways that do not deplete natural resources or harm the environment, especially by avoiding the use of fossil fuels and nuclear power.† It is one of the most commonly debated topics of this century.
