2. 3. A) Coal is the most widely used fossil fuel for electricity generation, as the cost for producing
steam via coal is 3 times cheaper than any other medium according to the Asian Coal Reserves
2013 they are also used in Steam locomotives to produce energy for the engine to work..
B) Diesel is used in Heavy commercial vehicles and trains, as they produce large amount of
energy for engine to work for transportation heavy goods. In the United States, 93 percent of the
energy we consume comes fromfossil fuels. We burn them in the form of gasoline and diesel fuel
for cars
4. A) What are Fossil fuels? how are they formed ? Where do they come from? Let’s simplify.
I’ll focus on these: Oil, Natural Gas, Coal. Before the age of the dinosaurs, steamy swamps filled
with giant trees and large leafy plants covered many parts of the earth.” As the trees and plants
died, they sank to the swamp bottom where they formed layers of soggy dense material called
peat. Over many centuries these beds of peat became buried by sand, clay and other mineral
deposits forming sedimentary rock As the weight of the sedimentary rock grew, the water was
squeezed out of the peat and the increased heat and pressure compacted the peat to form coal.
Most coal mined today is believed to have been formed about 300 million years ago. The early
stages of coal formation still continues today as trees and plants in swampy areas die and decay
to form peat. However, the process of making this new coal will take millions of years.
B) Fossil fuels we burn today were formed from the tissues of organisms that lived 100-500
million years ago. Organic material is broken down in an anaerobic environment = one that has
little or no oxygen. Bottoms of deep lakes, swamps, and shallow seas Organic matter is
eventually converted into crude oil, natural gas, or coal. Some regions have substantial reserves,
whereas others have very few. How long a nation’s reserves will last depends on: How much the
nation extracts, uses, and exports. Nearly 45% of the world’s proven reserves of crude oil lie in
the Middle East. The U.S. possesses more coal than any other country.People in developed
regions consume far more energy than those in developing nations. Industrialized nations divide
their energy use evenly between transportation, industry, and other uses. Developing nations use
energy for subsistence activities (agriculture, food preparation, and home heating). Developing
nations use manual or animal energy instead of fossil fuels. To harness, extract, process, and
deliver energy requires substantial inputs of energy. Roads, wells, vehicles, storage tanks. Net
energy = the difference between energy returned and energy invested. Net energy = energy
returned – energy invested. Higher ratios mean we receive more energy than we invest. Ratios
decline when we extract the easiest deposits first and now must work harder to extract the
remaining reserves.
