The Need To Search For Alternative Energy

The question of how to use energy for the constructive use of mankind with the least cost, economically and environmentally, is the greatest conundrum faced by the world at large. The pollution from using fossil fuels and nuclear waste have detrimental effects on all living species on the planet as well as the planet itself , from natural disasters , ozone depletion and diseases to smog and wildlife extinction. This has led scientists to come up with alternative methods of harnessing energy to minimize the debilitating effects of traditional energy sources on the environment.

Solar Energy

Solar energy is the use of energy from the Sun - it is the conversion of sunlight into electricity. This can be done by a variety of methods such as photovoltaic. Solar heaters can heat water tanks, swimming pools and water pumps for agricultural purposes. Technology has harnessed solar power for a variety of other uses as well, from metal smelting and solar cookers, to industrial chemical production, domestic electricity generation and vehicle fueling.

Wind power

Tidal power is a kind of hydropower where the energy produced by tides is converted into electricity and other forms of power. Though not in wide use, tidal power has great potential - as tides are a cause of gravitational forces and the rotation of the Earth, tidal power is virtually cannot deplete.

Wind Energy

One type of hydropower involves the use of the energy produced by the tides. The energy from the tides is transformed into electricity and other kind of power. Since the tides are generated by the gravitational forces and the rotation of the earth, tidal power has an astounding potential although it is not yet widely utilized. Moreover, it can't get exhausted.

Hydroelectricity

In countries with tropical weather, a commonly utilized energy source is hydroelectricity. It is generated by making use of the gravitational force of water that falls from a high source. Moreover, it is the most extensively utilized substitute source of energy. No dangerous substances are emitted by hydroelectric plants. It is a natural source of energy as well. Power plants supplied by hydroelectricity give off lesser degrees of greenhouse gasses as compared to conventional energy plants powered by fossil fuel. Although economically and environmentally the erection and maintenance of dams is not practical to be utilized widely, benefits prevail over the disadvantages of hydroelectric plants.

Nuclear power

Nuclear fission is a kind of reaction that could produce energy. By utilizing nuclear fission and with other nuclear technologies, energy can be harnessed. Steam energy is generated by nuclear reactors through heating water and converting the steam into electricity. Ships and other naval vessels make use of nuclear power.

Geothermal power

Heat that is amassed from below the earth surface produces geothermal power. Energy plants backed up by geothermal power run for 24 hours. When viewed from the economics perspective, this form of energy is very feasible than making use of fossil fuels which have varying costs. A whole urban community can be supplied by one big geothermal plant while villages and building structures can be powered by small ones. Moreover, geothermal plants are maintainable and do not release poisonous elements to the atmosphere.
