without further polluting the air and causing more depletion of non-renewable resources. It is by far the most efficient due to the operating costs being much lower then the actual costs for the energy from fossil fuels(GAO‚ 2004). Solar energy is the next most energy efficient‚ with the next alternatives being geothermal and tidal. Consequently‚ non-renewable resources are those that can not be replenished or renewed. Most of these resources are fossil fuels like‚ coal‚ oil and gas (Berg&Hager‚2007). Unfortunately

and manufacturing goods. Most of us do not even realise how dependent we are on fossil fuels and metal ores. However‚ they have become an indespensible part of modern technologically advanced society. Fossil fuels are unequally distributed throughout the earth consentarting in those areas where carbon-based life forms used to thrive. Since the invention of internal combustion engine‚ petroleum and other fossil fuels have become dominant all over the globe. Thus‚ countries in possession of them have

The lack of energy resources is one of the greatest challenges faced by government in Australia. Therefore‚ the new energy resources are promoted and developed such as nuclear power and renewable energy. Some in Australia argued that development of new energy resources not only alleviates the shortage of fossil fuels resources and protects the environment‚ but also reduces the

Because they cannot be renewed fast enough to keep pace with consumption‚ they are considered non-renewable and are the most commonly used type’s energy. Fossil fuels were formed over millions of years when decomposed plant and animal matter were buried by layers and layers of the earths crust and then it was transformed into carbon-rich material that is used as fuel.

Ever rising demand and consumption of conventional fueled energies despite fast depletion of the resources have encouraged development of green energy sources. Green energy technologies are modern day solutions to the problems of conventional energy generation. Wind power‚ as an alternative to fossil fuels‚ is plentiful‚ renewable‚ widely distributed‚ clean‚ produces no greenhouse gas emissions during operation. In this direction our project

Fossil fuel combustion‚ land-use change‚ increasingly intensive agriculture‚ and an expanding global human population are the primary causes for these increases. Other greenhouse gases found in our planet’s atmosphere include water vapor and ozone. Carbon dioxide is released into the atmosphere by the burning of solid waste‚ wood and wood products‚ and fossil fuels (oil‚ natural gas‚ and coal). Nitrous oxide emissions occur during

Community Solar Energy Alternative energy resources are being closely evaluated because of the depletion of nonrenewable resources‚ such as fossil fuels. Fossil fuels and other nonrenewable resources have damaged earth because of the amount of pollution that is released some‚ in which is known as Carbon Dioxide. Massive amounts of Carbon Dioxide are that is released into our environment every year further damaging our planet. Scientist has been effectively working on ways of conserving energy

Unless a person lives in a country where technology is prevalent‚ one’s life is most likely influenced by technology in one way or another. For example if one looks at the devices in a modern day home‚ a refrigerator‚ an electric stove‚ a blender or a toaster oven will be found. In the living room‚ one will most likely have a television and perhaps a computer. A large percentage of people own cell phones to stay connected with friends‚ family‚ colleagues and business associates. The most up to

Fossil fuels are dead plant and animal matter that has been compressed and heated over millions of years. They are burned to create heat‚ which in turn creates energy. However‚ with heavy industrialization (agricultural and manufacturing)‚ transportation‚ and personal energy use‚ our world’s fossil fuel supplies are rapidly depleting. Even more‚ fossil fuels pollute our environment. Scientists are on the

energy revolution that launched the industrial age. The catalyst to this epochal change was ordinary black coal - an energy rich hydrocarbon. A century later‚ oil and gas were added to satiate the thirst of industry. Man still relies mainly on these fossil fuels. Nevertheless many other sources of energy: hydro‚ solar‚ nuclear‚ wind‚ geothermal‚ biogas and wave have been taped. These sources of energy are not only renewable but clean as well.
