ESSAY ON ALTERNATIVE SOURCES OF ENERGY The law of conservation says that energy is neither created nor destroyed. When we use energy‚ it doesn’t disappear. We change it from one form of energy into another. A car engine burns gasoline‚ converting the chemical energy in gasoline into mechanical energy. Solar cells change radiant energy into electrical energy. Energy changes form‚ but the total amount of energy in the universe stays the same. Scientists at the Department of Energy think they have discovered

fuel sources. The most popular being fossil fuels. 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 search for alternative energy sources so the

The Definition of Conventional Sources of Energy By Don Shepard‚ eHow Contributor I want to do this! What’s This? Your Dictionary.com defines conventional as "not unusual or extreme; ordinary." This fits well with conventional energy sources in terms of being not unusual‚ however‚ the impact on society by these sources has been anything but ordinary and have actually been quite extreme. Conventional energy sources have demonstrated both extremely positive and negative consequences. These negative

ABSTRACT: The term “waste to energy” has traditionally referred to the practice of incineration of garbage. Today‚ a new generation of waste-to-energy technologies is emerging which hold the potential to create renewable energy from waste matter‚ including municipal solid waste‚ industrial waste‚ agricultural waste‚ and waste byproducts. The main categories of waste-to-energy technologies are physical technologies‚ which process waste to make it more useful as fuel; thermal technologies

I am lucky enough to live in the beautiful state of Colorado. Colorado has an extensive supply of conventional fossil fuel and renewable energy resources. Per EIA (Energy Information Administration) 2009‚ "The State contains several fossil fuel-rich basins‚ including the Sand Walsh‚ Piceance‚ Paradox‚ and San Juan basins in the west‚ and the Denver and Raton basins in the east. Ten of the Nation’s 100 largest natural gas fields and three of its 100 largest oil fields are found in Colorado. Substantial

Alternative Energy Sources [pic] Alternative energy is no longer a secret. Most of the world’s energy needs are fulfilled by fossil fuels including gasoline and coal. It cannot be denied‚ however‚ that their supply is no longer in a stable state‚ their prices have gone up and they have been found to cause damage to the environment. The negative effects of the use of fossil fuels are taking its toll on Mother Earth and mankind. Pollution mainly from the burning of fuels has long been pointed

Defined The environmental issue that my research will focus on is the continued use of fossil fuels as the primary energy source by our global economy: regardless of the proven adverse impacts‚ from our reliance on these nonrenewable resources; and in consideration of the circumstances regarding the existence of viable alternative sources of energy‚ given the application of equivalent technologies applied to their systems of conversion. The focus of this paper is not to identify evidence of the negative

Energy is one of the basic ingredients required to alleviate poverty and socio-economic development. The energy prospect is generally assessed on the basis of available commercial sources of energy i.e.‚ fossil fuel like gas‚ coal‚ oil etc. Worldwide‚ there is a major transition underway in the energy sector. Biogas can be a potential source of

Warming and Alternative Energy People are inflicting major damage to the Earth’s environment‚ and if we don’t do anything to stop the destruction soon‚ the results could be devastating. Most people know about global warming and think it may be a serious problem in the future. What most people don’t understand is that global warming is happening now‚ and we are already feeling some of its destructive power. Because of the dangerous effects of global warming‚ alternative energy sources need to be aggressively

Thanks to technological advances‚ wind energy is the fastest growing energy source in the world. Wind power is safe for the environment and does not produce any atmospheric emission or greenhouse gases. Since wind depends on the sun‚ it is a form of solar energy. As long as the
