Comparing solar and electrical energy

Introduction

The technology utilizes massive quantity of modern electricity. This is in general produced in a power plant that converts added forms of energy into electrical energy. Every power generated method has pros and cons, although numerous of them cause ecological apprehensions (Chiras, 2010).

Solar Energy

Solar energy is the power formed by the sun and is transformed to valuable energy by humans; either to generate electrical energy or warm something. Each year, the sun casts 4,000 times additional force than they utilize, so their latent is virtually unlimited. The strength of energy accessible at a specified position on earth depends on the latitude, day of the year, and time. Furthermore, the quantity of energy that can be composed lies on the direction of the obtaining tool. Solar energy is extracted from the light of the sun. This can be done directly with photovoltaic cells, or by use of sets of mirrors to concentrate sunlight on a common point that is extremely hot. This heat can heat up water into steam which passes through a turbine with a generator can produce electricity (Solar Energy International, 2004).

In any case, a large space is needed of ground to receive the necessary amount of sunlight. Deserts are the usual locations chosen. The manufacture of solar cells causes the release of pollutants into the environment and the emissions associated with the energy to make and install cell-El energy pay back, time needed to produce the energy used throughout the production process, is located around three years, the 30-40 year life of the cells. Once one has built a solar collector, its environmental impact is not serious. It occupies a large portion of land, denying its use to the fragile systems of the desert, and the heated air can lead to slight changes in local climate. The mirrors or cells must be clean, which probably requires a certain volume of water. Where possible, solar power is usually fully compatible with the environment.

Solar energy refers mainly to the use of solar radiation in the practical purposes. In any case, derive all sources of renewable energy, with the exception of tidal energy and geothermal energy, energy from the sun. There have been some projects to harness solar cells relatively small, by posting on the roofs of houses. In general, the power generated is not sufficient to reimburse costs to current electricity prices in the short term, so that when there are no government subsidies, the method is rarely used. Normally, it is more practical to use small solar collectors to heat water directly, addressing the domestic hot water needs (Markvart, 2000).

How to Get Solar Energy

The below mentioned are the ways by which solar energy can be obtained in particular means. These encompass the techniques that imply on capturing solar power.

Solar thermodynamic

The thermodynamic solar is a solar technology that uses solar heat to generate electricity, on the same principle as a conventional power plant (production of high-pressure steam which ...
