Alternative Energy Sources

An alternative energy, or more precisely an alternative energy source is one that may replace the current energy sources or energy, whether their lower polluting effect, or primarily for its possibility of renewal. Energy consumption is one of the major gauges of progress and welfare of society. You will most probably be asked to write an argumentative paper on the use of alternative energy sources. The concept of "energy crisis" appears when energy sources from which the company supplies are exhausted. An economic model as the current operation of which depends on continuous growth requires an equally growing demand for energy. As sources of fossil and nuclear energy are finite, it is inevitable that at any given time demand can be supplied and the whole system to collapse, unless they discover and develop new methods for energy: these would be alternative energy. Together with this is that the abuse of conventional energy present today such as oil from coal combustion among other issues carry with them as progressive worsening pollution, increased greenhouse gases and perforation of the layer ozone.

Scientists are currently looking for solutions to solve this impending crisis. We are ready to write a custom essay describing the following types of renewable energy: Wind energy is the kinetic energy or movement that contains the wind, which is captured by windmills or wind turbines. Hydropower, which consists of attracting the potential energy of waterfalls. Tidal energy, which is extracted from the tides (so similar to hydropower). The wave energy, which is produced through the power of the waves. Solar energy, collected in the form of direct heat at high temperature in various types of solar power, or by low temperature solar home, or in the form of electricity using the photoelectric effect by photovoltaic panels. Geothermal energy is produced by exploiting the heat from the subsoil in areas where this is possible. Biomass energy, which is produced by decomposition of organic waste, either directly or by burning fuel. Discussion of alternative / conventional energy is not a mere classification of energy sources, but represents a change that will necessarily have to occur during this century. It is important to note that alternative energy, although renewable, is finite, and like any other natural resource will have a maximum limit of exploitation. Therefore, even if we make the transition to these new energies gently and gradually, we are not going to allow continuing with the current economic model based on perpetual growth.
