the environment at risk. Air pollution is currently one of the five leading causes of death worldwide and the usage of fossil fuels is a major factor contributing to this. (Future talk: clean renewable energy September 2013). Fossil fuels are finite sources of energy; while the demand for energy will continue to increase‚ there will still be a decrease in amount of fossil fuels available‚ which means humans will need to find other sources of energy.

Bio-fuels Menno van Amen TV4E 13-06-2013 The production of bio-fuels has become a controversial topic as the 21st century progresses. Lately the production of biofuels has been discussed quiet frequently and many people have started focusing on the question if the production of biofuels actually is environmental friendly. Firstly‚ what is a biofuel? Biofuels refer to any solid‚ liquid or gas fuel that has been gotten from biomass. They produce biofuels by growing plants‚ growing sugar

DIGITAL FUEL LEVEL INDICATOR ABSTRACT Imagine this. You are on a highway and suddenly your vehicle stops. To your horror‚ you find that you are out of fuel. You check the fuel indicator and find that it has gone repair and is pointing to a higher value on the scale. This is a major shortcoming of the ANALOG FUEL LEVEL INDICATOR. This drawback can be redressed by simply switching the indicator to DIGITAL type. Our project deals on this mechanism and helps to explain the process which can be

Advantages and Disadvantages of Renewable Fuels Solar Energy: Advantages: -Energy is free although there is a building cost. -Causes no pollution‚ however‚ energy may go into machines that produce pollution. -Solar energy can be used in remote areas where it is too expensive to extend the electricity power grid. -Estimated that the worlds oil reserves will last for 30-40 years whereas solar energy is infinite. Disadvantages: -Solar energy can only be harnessed when it is daytime
