Coal and oil, for example, are consumed with incredible speed. But coal mines become exhausted. The situation is the same with oil. These sources of energy are not renewable and there is a need to discover other energy sources.
Alternate Energy Sources Introduction: Alternate energy refers to forms of energy that are constantly replenished by the Earth. The energies are natural occurring and are tapped for conversion into other forms of energy.
Energy cannot be destroyed but can be converted into other forms.
Research in alternate sources of energy has been extensively carried out. This is affiliated with the looming energy crisis being experienced globally. The global demand for energy is higher than the amount of energy being generated.
The global economic equilibrium is unbalanced leading to market failures and poor policies for energy generation. A cleaner source of energy in attempts to reduce emission of green house gases from fossil fuels also forces the need of less toxic fuels.
This resource is vast as it is almost times the global consumption of energy used by humans Solar energy requires high capital cost in investment, intermittency and modest conversion technologies making it cumbersome to initiate use in the form of energy.
The greatest challenge in solar technology is in the discovery of new solar energy mechanisms that are more efficient and less capital intensive. The universal energy potential ranges from 2.
The solar energy market share is significantly low Developed countries have progressively invested in solar mechanisms with projections with projections estimated at Most of the solar produced in these countries is used locally.
The global pricing of solar power by end of year was at 18 cents per kilowatt-hour. Compared to coal and natural gas, the price is three times higher.
This fact lags the transition from fossil fuels to solar energy.ADVERTISEMENTS: Here is your short essay on Energy! Energy is a primary input for almost all activities and is, therefore, vital for improvement in quality of life.
Explain how these scientific laws apply to energy use, energy conversions, and the need for energy efficiency. Describe the pros and cons of the following energy types, writing 1 paragraph for each: Fossil fuel: Oil, natural gas, and coal.
