and lighting. The largest sources of energy in the world are oil (34%)‚ coal (26.5%)‚ and gas (20.9%)1‚ adding up to over 80% of global energy. These types of fuels are called fossil fuels because they are found in fossil carbon deposits in the ground. An important difference between fossil fuels and other sources of energy is that fossil fuels are non-renewable‚ meaning that once they are used‚ they are gone and cannot be replenished. Other common sources of energy are nuclear‚ hydro‚ and solid biomass

Research done by Mann and other climate scientific points out that there is a serious threat to our planet as a result of the overuse of fossil fuels and the sharply rising levels of the gases as we continue to burn more and more fossil fuels. According to Michael Mann‚ he and other scientist over the past decades have become the victims of

ENVIRONMENTAL PROBLEMS BIODIVERSITY LOSS Biodiversity - refers to the number and size of populations in a community; variability of species in an area In general‚ there are three categorical levels of biodiversity: 1. Genetic biodiversity - involves populations‚ individuals‚ chromosomes‚ genes and nucleotides 2. Taxonomic biodiversity - include kingdoms‚ phyla‚ orders‚ families‚ genera‚ species‚ subspecies and populations - for practical reasons‚

This is called “non-renewable” energy resources. Non-renewable energy resources consist of fossil fuels (petroleum‚ coal‚ natural gas) and uranium (nuclear energy). The amount of pollution released from producing energy is a big concern‚ but not all of the energy resources emit the same amount of pollution. The alarming fact is‚ recently‚ many of

I believe alternative energy would be beneficial to our society‚ especially if it is used in transport; there is many other better‚ leaner and reusable energy sources out there‚ for example fuel for vehicles pollutes the air and yet can be changed by using a more natural source that doesn ’t create as much pollution if not any If we were to experiment more with the usage of natural elements‚ without mentioning that it would be cheaper for

there is an increase in diseases‚ infections and death that is caused by pollution. One such pollution is air pollution‚ which is the presence in the atmosphere of harmful gases‚ liquids‚ or solids. Today we live and work in a world driven by a fossil fueled economy. The cars and other forms of transport that we run on are primarily on gasoline derived from oil. Our homes and work places stay heated and cooled using electricity generated by utilities heavily dependent on coal. Many air pollution

From my research and readings‚ I‘ve concluded that‚ the foremost effect that burning fossil fuels has on our environment is the greenhouse effect‚ also known as global warming. Carbon dioxide‚ which is also known as greenhouse gas is released during combustion of fossil fuels and is the cause of this catastrophe. But yet‚ other

Feasibility of Residential Wind Turbines As Americans work to reduce fossil fuel dependence and look to more environmentally friendly energy sources‚ the use of wind energy technology has become the fastest growing segment of the energy market. The feasibility of residential wind turbines mainly comes down to wind resource‚ economic feasibility‚ and consumer acceptance. The use of residential wind turbines is certainly feasible in some areas‚ however; I do not believe they are feasible on a wide-scale

can help reduce the price of economic costs of some necessary utilities. Solar energy is a substitute and also an opportunity cost for the energy we use now‚ called fossil fuels. There are many benefits to switching from fossil fuels to solar energy. Solar energy can help lower the cost of the energy we use now by burning fossil fuels‚ changing the supply and demand of the product. Also‚ it can help the pollution that is causing further health and economic problems. Since there are many benefits
