Biofuels Biofuels are Fuels made from Biomass Biofuels are made from plants‚animals‚ or their waste products. Here I have listed three examples of biofuels beneath. 1 Micro-organisms decompose waste materials to produce biogas. 2 Biogas is usually about 70% methane and somewhere between 20 and 30 % carbon dioxide 3 the way we use it to generate energy is to burn it to heat up water which will then turn a turbine to produce electricity. It is also heard of to heat the water to steam which

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

Hi guys‚ my name is Betty. I am the lead of my group today. I am goanna talk about fuel prices. The issue of fuel is very complex. First‚ what is fuel?

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

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
