Alternative Energy Represents Attractive Options

The traditional form of energy the world over refers to fossil fuels. This motley term includes crude oil, petroleum products, coal and the like. Fossil fuels are carbon-derived substances that have formed from the remains of dead organic matter over a period of time spanning millions of years. As a source of energy, their supplies are limited, and cannot be replenished. Moreover, the reckless consumption of coal and petroleum worldwide has naturally drawn attention to the environmental hazards of this mode of energy. Global warming, the rising incidence of asthma, and various other ills may be traced to an increasing burning of fossil fuels. As a result, the need for the adoption of alternative energy modes has made itself starkly felt in recent times. Several types of alternative energy have been developed in varying degrees. In the sections below, we briefly discuss four major forms of alternative energy.

Hydroelectricity: Ancient and Developed Mode

Energy derived from water is known as hydroelectricity. This essentially employs the force of falling water, as seen in naturally occurring waterfalls, to turn turbines for the generation of mechanical or electrical energy. Hydroelectricity is among the oldest and most widely used forms of alternative power. Regions that have a number of rivers and streams make fertile ground for the construction of dams to store water in huge amounts. Hydroelectric dams can provide power to an entire city at cheap tariff. However, the construction and management of hydroelectric dams do entail considerable finances and expertise respectively. An index of the popularity and success of this mode can be gauged from the fact that presently, almost 20 percent of humanity’s power needs worldwide are being met by hydroelectricity. In addition, hydro power comprises nearly 90 percent of all the power that gets generated globally by the combined diverse alternative forms of energy.

Wind Power: Feasible but Unreliable

Employing the force of the winds for the generation of electricity recommends itself as a form of alternative energy in its being inexpensive, easy to operate, and environment-friendly. Areas that are home to intense winds make ideal locations for the setting up of windmills. Such regions can merrily employ their force to turn windmills that can be used to generate oodles of electricity. Windmills are easy to construct and the force of the winds causes them to move, and to eventually generate electricity. However, on the flip side, winds have no reason to be punctual, as it were, and so make for an unreliable option. The associated technology is being used with success in various parts of the world. The Netherlands has emerged as a prime example of an effective utilization of this form of alternative energy.

Nuclear Energy: A Debatable Option

Nuclear power has the potential of generating huge amount of electricity. However, this mode has certain inherent factors and risks that cannot be ignored. Indeed, nuclear technology remains the exclusive reserve of a certain elite band of nations. The fear of misuse of related technology and materials is too real in today’s terrorism-racked world to be ignored altogether. Over 14 percent of the global electricity in 2007 came from nuclear power plants.

Tidal Energy for Coastal Areas

The naturally occurring tides in the coastal areas are a clean, renewable and cost-effective form of alternative energy. This mode employs the rise and ebb of tides that occur owing to interplay between the gravitational forces of the sun, earth and moon. Since tides are not dependent on the weather, their motions can be predicted with a fair degree of accuracy. The motion of the tidal waves is employed to firstly fill reservoirs of water. The water is then released through turbines that generate electricity.

We are running out of natural resources which need to be preserved, so alternative energy sources are necessary to deal with this crisis. More development and research is needed in this area so that we can move ahead to look for replacements for the near future. Currently we are dependent on foreign countries for their export of oil for our use, and we still rely on the old use of fossil fuels. We need to look beyond this and start to use available alternative energy sources, of which there are many. The sooner we start the better so we can avoid the worsening situation which experts believe is looming over us. Once alternatives have been sourced, we need to explore how best to use them so that systems can be put in place at the earliest convenience.

wind power is very much a possible alternative as many wind turbines are now in use. It is less expensive to set up and we continue to develop them steadily for use as efficient energy. There are many wind farms which have been developed worldwide and strategically placed to avoid any damage to the environment and also birds.

Most of us have heard of solar energy which is another energy source which is a good workable alternative. We have all seen solar panels which are manufactured with many solar cells that harness the sun’s energy so that it can be converted into electricity for many uses like heating water. This resource is very environmentally friendly as it does not pollute the air.

One energy that most of us have not heard of is ocean energy. This is renewable energy from the sea which experts believe to have huge benefits as a power source for the future. There is the potential to generate an enormous amount of energy and for years countries like France, Ireland and Scotland have already used generators to successfully use this source for power.

Hydroelectric power is one of the oldest alternative energy sources. Powerful generators uses water and converts it into electricity. It is limited in that you can’t build large dams anywhere, which were largely used to control floods and for irrigation. They also affect natural habitat although they are clean running and good for the environment. There are now smaller electric generators now being set up to so they can be more localised.

Geothermal energy is a natural resource of which there is an abundance, and is found just below the earth’s surface. We produce this type of energy by using the earth’s molten core to heat up water. The steam that is produced from the heated water is then used for running turbine engines so that it is converted to electricity. Experts say that more extensive research should be done in this area to that we can learn how to tap into this geothermal energy.

Instead of using gas to run our cars and engines we can use Ethanol. It is derived of strawberries, sugar cane, wheat, wood and wood cellulose. This type of fuel source may not be as economically feasible according to experts, so it may not be viable as an energy source.

Biodiesel energy could potentially be another good energy source. It is made of plant oils. Seeds, soybeans and other oils could potentially be used to make up biodiesel, although the progress on this is slow to develop as an energy resource. If we to use this on a large scale it would not be feasible economically, although it is much more clean running than diesel as it is oil based. It is also clean and environmentally friendly.
