However‚ the share of coal and coke increased from 9.1% in 2005 to 11.2 % in these years and only 2.5% came from the non-fossil source of hydro power in 2010. From the statistics‚ it shown that there were a slightly fall for the average annual growth rate (%) of crude oil from 3.6% to 3.5%‚ and coal from 17.2% to 8.8%. Nonetheless‚ there were and increased in the natural

Power Resources Resources used for producing energy or power are known as power resources. There are many types of power resources like fossil fuels‚ oil and gas‚ wood and coal‚ solar power‚ hydro power‚ nuclear‚ wind power‚ etc. Importance of Power Resources I. Power resources are use for producing energy for running machines in industries. II. Power resources are use to running agricultural machines.

Natural resources are all the things on Earth that support life. Plants‚ animals‚ air‚ and water are natural resources. Natural resources are also things that people use to make life easier. Your life is easier because you can ride in a bus powered by gasoline. You can cook your dinner in a microwave oven powered by electricity. People use natural resources to make gasoline and electricity. People use many natural resources to make their lives easier. There are different kinds of natural resources

To our luck‚ the discovery of fossil fuels‚ substances created from the decomposition of ancient organisms and fossils like oil‚ natural gas‚ and coal‚ allowed us to replenish our tools’ thirst for energy; in fact‚ each of these fossil fuels have their own traits‚ perks‚ and downsides that separate them from each other. For instance‚ coal is a solid‚ dark mineral that is commonly

cannot stop global warming‚ according to a Providence Journal article. Sea levels will rise an average of three to six meters by 2100. Studies show that 839 square kilometers of the New England coastline will be submerged. Biodiesel is a renewable fuel produced from vegetable oils. Most biodiesel is made either from crops‚ recycled cooking oil‚ or animal fats. Among them‚ recycled cooking oil is the most effective resource to make biodiesel since it does not compete with food resources. Biodiesel

Earth’s surface have increased by 1.1 degrees Fahrenheit during the last century‚ faster than any time in the last 1000 years (Rauber 41). Consequently‚ the 1990s was the warmest decade in the last 1000 years (“Global Warming”). As humans emit fossil fuels‚ greenhouse gasses slowly warm the Earth’s atmosphere (“EPA Global”). This gradual process is known as global warming. As glaciers begin to melt‚ sea levels rise and coastal areas in Florida may suffer immense losses (“Beach Erosion”). Florida’s

CE : Section 5 Fossil Fuels 1. 93 1(c) Alkenes can be obtained from petroleum fractions by a process called ’cracking’. Using a suitable petroleum fraction‚ a student carried out this process in the laboratory and collected the gaseous product over water. (i) What is ’cracking’ ? (ii) Draw a labelled diagram of a laboratory set-up that can be used for carrying out the process and collecting the gaseous product. (iii) An important safety precaution in the experiment is to prevent sucking

wrong. There are two main sides to the argument of the cause of global warming; those who believe that global warming is just a natural phase in the climatic habits of earth‚ and those who believe humans are the direct cause through the burning of fossil fuels and other processes. Each side of the debate provides much scientific evidence that proves there point. In an article released by the Dept. of Commerce‚ NASA claims "...the solar increases do not have the ability to cause large global temperature

chlorofluorocarbons‚ which destroy the ozone more slowly (maybe take this out?). Burning fossil fuels cause another type of air pollution that releases very small particles into the air. The three main forms of fossil fuels are natural gas‚ coal‚ and oil. Fossil fuels take millions of years to form‚ and are made by layers of organic matter made into sediments over time. Eighty percent of the world’s energy comes from fossil fuels (www.solcomhouse.com‚ 2/2/07). Crude oil is a dark sticky liquid made from hydrogen
