Alternative Energy Forms Successfully Developed

The traditional fossil fuels involve their burning for the production of energy. Alternative modes of energy are gaining substantial attention and popularity all across the globe for a variety of reasons. The alternative energy types are usually renewable, easy to use, cost-effective, and friendly to the environment. There are several types of alternative power available these days. Each mode has its peculiar advantages and disadvantages. However, sufficient development has been made in certain types of alternative energy — notably hydroelectricity, nuclear energy and solar power — to warrant the conclusion that the sovereignty of fossil fuels as the mainstay of humanity’s energy needs has little reason to continue indefinitely. This is all the more so because oil prices have maintained ca steady upward climb, and the consumption of fossil fuels is under the scanner for its believed detrimental effects on the environment.

Abundant Water: Excellent Energy Source

Hydroelectricity accounts for about 90 percent of the global energy produced from renewable sources, as well as nearly 20 percent of the overall electricity produced worldwide. Hydel power stems from the force with which water falls. Dams are constructed to store water, which is directed to fall down from an enormous height to move turbines that generate electricity. This mode of alternative energy is among the most ancient, widely used and popular forms available. It has proven effective in meeting the energy requirements of huge populations at cheap rates.

Each With Its Own Paraphernalia

Alternative Energy forms are a motley category and include several different modes that vary markedly from one another. Hence, to discuss how these energy sources work, no general pattern can be outlines. Each energy source mandates its own set of principles and mode of functioning. However, we may well briefly study a few of these sources of power as follows.

Solar energy is a ubiquitous alternative energy form that can be tapped with the means of solar panels, solar calculators and photovoltaic cells. Solar energy finds applications in warming homes and in generating electricity. The solar technologies are categorized into active solar and passive solar, based on the mode adopted for the capture, conversion and distribution of sunlight. Active solar methods use photovoltaic panels and other mechanical gadgets to transform the sun’s rays into more productive forms. Passive solar modes pertain to orienting a building towards the sun or choosing substances with better properties of dispersing light.

Wind energy employs the force of the moving winds to move turbines that lead to the generation of electricity. This alternative energy form is best located in places that are characterized by gusty winds. Windmills are built for the purpose of exploiting the power of the winds. The technology involved is simple and can be replicated anywhere windy with success.

Nuclear energy may be either nuclear fission or nuclear fusion. The former involves splitting of the atom, while the latter deals with the merger of atoms. Nuclear fission has been plagued by safety concerns over the disposal of radioactive waste products that are detrimental to the environment and public health.

Tidal energy draws from the force of the tidal waves. The rise and ebb of the tides occur owing to a complex interplay among the gravitational forces of the sun, moon and earth. The tides are independent of the local weather and lend themselves to easy prediction. The waters are collected and led to mive turbines for the generation of electricity.

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.
