TESTING YOUR COMPREHENSION 1) Why are fossil fuels our most prevalent source of energy today? Why are they considered nonrenewable sources of energy? Today‚ the three main fossil fuels that are in demand are oil‚ coal and natural gas. These fossil fuels are prevalent because they are efficient to burn‚ ship‚ and store based on high energy content. Fossil fuels also provide for our daily needs such as transportation‚ heating‚ cooking and electricity. Based on our current rates of consumption‚ we

two types of energy resources: Non-renewable energy resources: These are the kind of energy resources that can not be produced or used once more. This indicates non-renewal resources perish after single use. The example of such resources are oil‚ coal etc. Renewal energy resources: These are the types of energy resources which might be reproduced again. The example of renewal energy resources are wind‚ solar energy‚ water etc. The renewal resources are a much better choice because this energy

Global warming is caused primarily by carbon dioxide from burning coal‚ oil and gas. Certain gases that trap heat are building up in Earth’s atmosphere. The primary culprit is carbon dioxide‚ released from burning coal‚ oil and natural gas in power plants‚ cars‚ factories‚ etc. (and to a lesser extent when forests are cleared). The second is methane‚ released from rice paddies‚ both ends of cows‚ rotting garbage in landfills‚ mining operations‚ and gas pipelines. Third are chlorofluorocarbons (CFCs)

However from 1870 – 1914 the world saw an overall economic boom attributed to a number of factors specifically; relative stability‚ efficiency in production‚ coal and steam power and innovations in finance. During the first collapse‚ the world was transitioning

Ozone depletion describes two distinct but related phenomena observed since the late 1970s: a steady decline of about 4% per decade in the total volume of ozone in Earth’s stratosphere (the ozone layer)‚ and a much larger springtime decrease in stratospheric ozone over Earth’s polar regions. The latter phenomenon is referred to as the ozone hole. In addition to these well-known stratospheric phenomena‚ there are also springtime polar tropospheric ozone depletion events. The details of polar ozone

Using fossil fuel in daily life for transportation‚ industry and producing electricity causes many problems to people‚ environment and animal. To preserve fossil fuels need large amount of money. The depletion of fossil fuel makes high cost and it keep rising that impact on people spending. Burning fossil fuels releases carbon dioxide‚ methane

Pollution is not a new phenomenon. In fact‚ pollution has been a problem since the appearance of our earliest ancestors. Increasing human population have opened the door to more bacteria and disease. During the Middle Ages‚ diseases such as cholera and typhoid fever broke out all across Europe. These epidemics were directly related to unsanitary conditions caused by human and animal wastes‚ and garbage. In 1347‚ the bacterium Yersinia pestis‚ carried by rats and spread by fleas‚ caused the "Black

increasing demand for energy as a means of survival‚ from its usage for cooking and warmth‚ all the way to electricity generation for production and agricultural activities. Today‚ over 80% of energy consumption comes from fossil fuels‚ which include coal‚ oil and natural gas (Irvine‚ 2011). However‚ those fuels are not renewable and won’t last for more than a few decades or even less. With the increase of population comes the increase in demand for energy.
