Introduction

Renewable energy I am an environmentalist who is in favor of using renewable sources of energy rather than non - renewable sources. There are several types of renewable resources of energy. 1. Solar energy. 2. Wind energy. 3. Hydroelectric energy. 4. Geothermal energy. 5. Biomass energy. It is better to use renewable resources of energy rather than non - renewable sources in the long term. Eventually the limited supplies of non renewable sources of energy will finish. You would then need to find another mean. Why wait for the non renewable source of energy to finish instead we can use renewable sources of energies. All renewable source power stations do not produce emissions that pollute the environment. ...read more.

Middle

Iron and aluminum come from nonrenewable ore deposits. Once a deposit is mined, it cannot be replaced. The natural resources such as trees form biomass energy. This saves limited oil reserves. Solar energy is very efficient compared to coal, oil and gas powered stations. The efficiency of a solar powered station varies between 40% and 80% but for an oil powered station it may range 30% to 40%. A solar powered station is therefore more ideal than a coal powered station since much of the energy is lost. However users currently pay 6 to 7 cents per kilowatt-hour for conventionally generated electricity. Eventually as renewable sources of energy becomes more popular the price will drop as no fuel cost is needed. ...read more.

Conclusion

The long term the cost of the renewable source of energy will decrease. This is because you would not need to pay for the source of energy for the renewable type. E.g. you would not need to pay for sunlight. Only the running cost would be needed. If however you continue to use non-renewable sources of energy you would need to pay for the fuel and running costs. E.g. If I build a non - renewable source power station and pay $ 1000,000 to construct, $500,000 for fuel and $100,000 to run I would only need $1000, 000 (for hydro =electric power station) to construct a renewable source power station and $50,000 to run. You would therefore save approximately 1/2 a million in money and the use of limited non-renewable resources. ...read more.

    It can be used in a business. Solar energy can be stored in batteries to light a roadside billboard at night. Or the energy can be stored in a battery for an emergency roadside cellular telephone when no telephone wires are around. Some experimental cars also use PV cells.

    It is easy to transport along pipes, and gas power stations produce comparatively little pollution. Other fossil fuels are being investigated, such as bituminous sands and oil shale. The difficulty is that they need expensive processing before we can use them.

    It is from livestock's such as cows, pigs and goat that we derive foodstuffs such as milk, meat and cheese among others. High yield protein foods for example, can be obtained from these products and as we all know proteins are bodybuilding foods.

    As their remains built up on the ocean floor, layers of sediment were formed and gas was produced by heat and pressure. Gas is cleaned and processed after it has been taken from the ground to get rid of impurities.

  2. Non renewable energy resources.

    Petroleum is crude oil, a naturally occurring liquid that can be distilled or refined to make fuels, lubricating oils, asphalt, and other valuable products. The word petroleum comes from the Latin petra, meaning "rock," and oleum, meaning "oil." Used in a broad sense, petroleum also refers to natural gas and solid asphalt, or tar.

  1. What is Renewable Energy?

    Most solar water-heating systems have two main parts: the solar collector and the storage tank. The collector heats the water, which then flows to the storage tank. The water stays in the storage tank until it is needed for something, say a shower or to run the dishwasher.

    Thus concern for proper resource management and conservation includes a careful monitoring of resource extraction and concern for the direct and indirect effects of resource use on the environment. A third issue is that of equity of distribution of the world's usable resources.
