we mean by fossil fuels and explain why they are an attractive source of energy: Fossil fuels are energy sources such as petroleum‚ natural gas‚ and coal which contain the stored radiant energy of organisms that lived millions of years ago (Tillery‚ Enger‚ & Ross‚ 2009‚ p. 67). Fossil fuels are an attractive source of energy because they are accessible and cheap. Describe two different energy alternatives to fossil fuels in detail. Discuss how they work‚ how they compare with fossil fuels‚ and

Modern Transportation is such a vital part of life in Western civilizations that there is no way to live without it. First world societies have glorified the use of fossil fuels and combustion engines which emit greenhouse gasses into the Earth’s atmosphere. In addition to the high amount of greenhouse gas emissions‚ humans are using up fossil fuels at an alarming rate. It is pivotal that humans find a to achieve sustainable‚ zero emission transportation. Convincing a population to switch over to zero

Renewable energy is energy from natural resources such as sunlight‚ wind‚ rain‚ tides‚ and geothermal heat‚ these resources are naturally replenished. Renewable energy does not harm the environment or deplete any of our natural resources like fossil fuel. Renewable energy is not subject to sharp price changes because it comes from natural resources. Biomass is currently the largest U.S. renewable energy source with more than two hundred existing bio power plants providing energy for one point five

They are considered alternatives because they can be future replacements for the fossil fuels that now meet a considerable portion of our energy needs.

improving rapidly. Someday‚ it may provide a clean and abundant source of power. Solar energy is a very useful resource. Today 80% of the energy we use comes from fossil fuels and about 1% comes from solar energy. Fossil fuels are nonrenewable‚ that means that they are used up faster than they could be replaced. Also fossil fuels limited and cause pollution. Recently‚ there has been talk about creating a whole livable society in which all essential sources of man-made energy‚ which

of humans making it human-caused. One of the causes of global warming is greenhouse-gas effect. It will continue for centuries even if and when greenhouse-gas emissions are stabilized in the future. Humans are helping to cause global warming by "Fossil fuel use‚ agriculture‚ and land-use change are fundamentally affecting the systems on our planet‚" (Science News (2009) according to Achim Steiner‚ executive director of the United Nations Environment Programme. In 2001 the panel that Achim was on

1950s. Air pollution had reached such a serious stage that it caused the London Smog in 1952 that caused 4000 deaths and a host of other related ailments among the Londoners. One of the main causes of the serious air pollution was the burning of fossil fuels by the many manufacturing industries producing iron and steel‚ automobiles‚ machinery‚ textiles and food. Coal and Oil were the main sources of fuel for the factories which resulted in the release of carbon dioxide‚ sulphur dioxide‚ smoke

possible solutions. The predominant factors resulting in the warming of the earth are the emissions of CO2 and deforestation. CO2‚ which damages the ozone layer‚ comes from several sources‚ but the most problematic are those coming from the burning of fossil fuels from power plants. This releases thousands of tones of CO2 into the atmosphere every year. Another cause of these emissions is the burning of gasoline for transportation‚ which continues to increase because of our demand for cars and also

change. It relates to the amount of greenhouse gases produced in our day-to-day lives through burning fossil fuels for things like electricity‚ heating and transportation. A carbon footprint is made up of the sum of two parts‚ the primary footprint and the secondary footprint. The primary footprint is a measure of our direct emissions of carbon dioxide (CO2) from the burning of fossil fuels. These fossil fuels are coal‚ oil and natural gas‚ they are all non-renewable and currently running out. Some estimates
