the key sources of energy means; fossil fuels are being depleted in a rapid mode which reflects that we need to concentrate over alternative sources of energy that could also prove to be eco-friendly. But‚ before discussing that it should be better to have an idea about the current scenario and where we are standing today in context of availability of energy resources. At present‚ approximately 80 percent of the energy used by us is supplied via fossil fuels which are called non-renewable energy

FUEL OIL BURNERS By Mark Butterfield March 09 INTRODUCTION The history of burners dates back to the early shipping days‚ when fuel oil first started replacing coal as the ships’ primary fuel source. Since then‚ burner designs and construction have come a long way‚ but the principles behind their operation has remained the same. All makes and types of burners have two things in common They need to atomise the fuel They need to mix the fuel with the air needed for combustion

What is Alternative Fuels Alternative Fuels come from resources other than petroleum. Alternative fuel uses sources like corn‚ vegetable oils‚ animal fats‚ natural gas‚ propane and hydrogen. Various Alternative Fuels are produced domestically‚ thus reducing our dependence on imported oils and some are derived from renewable sources. Alternative fuel produces less pollution than normal gasoline or diesel (U.S. Department of Energy‚ n.d. ). Alternative fuel is produce for a variety of vehicles

Ethanol‚ a Fuel? Ethanol fuel is a type of alcohol found in alcoholic beverages that is often made from common agricultural products. It is either mass-produced by fermentation of sugars or from cellulose. Wheat or corn kernels are ground in a hammer-mill to expose the starch‚ the ground grain is then mixed with water‚ heated briefly and enzymes are added to convert the starch to sugar using a chemical reaction called hydrolysis. Yeast is added to ferment the sugars to ethanol and finally the

A Fuel Alternative. The Search for an Alternative Fuel to Save the Environment… And Our Pockets. Long gone are the days were one could drive into a petrol station and fuel up your highly inefficient gas guzzling vehicle without a care for the environment and sustainability. The recent spike in the price at the bowser‚ damage to the environment and diminishing reserves has made it clear that a new‚ sustainable and clean fuel must be created in order for our vehicles and economy to operate.

Ethanol fuel is ethanol (ethyl alcohol). Ethanol‚ also called ethyl alcohol‚ pure alcohol‚ grain alcohol‚ or drinking alcohol‚ is a volatile‚ flammable‚ colorless liquid. A psychoactive drug and one of the oldestrecreational drugs known‚ ethyl alcohol produces a state known as alcohol intoxication when consumed. Best known as the type of alcohol found in alcoholic beverages‚ it is also used in thermometers‚ as a solvent‚ and as a fuel. In common usage‚ it is often referred to simply as alcohol or spirits

Disadvantages of alternate fuels The truth about the manufacturing and use of alternate fuels‚ as with everything else in life‚ is a mix of benefits and cost. Electricity is one of the alternate fuels that made it to production. The Chevy Volt is one such vehicle. The problem with this car is that it cost $41‚000 to buy one‚ and the battery life for a charge is only 37 miles. There would be no value for us to use electric cars. (Courture‚2011). Ethanol

While fossil fuels are critical for the operation of our world their inefficiency and environmentally damaging characteristics take away from their appeal. Currently there are no suitable alternatives to our natural resources because they supply such a large amount of energy to so many people. Because of this research is being conducted to make our resources more efficient‚ and to find alternatives. This essay addresses the environmental impacts of our fossil fuels.

The Fossil Fuels Introduction Fossil Fuels are a non-renewable energy source. They are found in Earth’s depositions made over millions and millions years ago and are called non-renewable because they can’t be used again once they are spent. There are three major forms of fossil fuels: coal‚ oil and natural gas. COAL Coal is made up of carbon‚ oxygen‚ hydrogen‚ nitrogen and some amounts of sulphur -Three main types of coal: • Anthracite : the hardest and has the most carbon in

Fossil fuels Oil 1) Oil is produced in Middle Eastern countries‚ Saudia Arabia accounting for 13.1 per cent of the world total‚ America 16.5 per cent and Africa 12.1 per cent. Although the Middle East has a lot of oil reserves not much is consumed. North America‚ Europe and Eurasia consume a lot of oil. This is due to the countries being MEDCs so they will need more fuel as the demand is higher. 2) The factors which cause oil prices to increase are from supply shocks (the OPEC oil embargo
