Evaluating Automobile Fuel Essay Example for Free

Evaluating Automobile Fuel EssayThe alternatives to mobile fuels argon compressed gases and electric power, however, both are viewed as inferior by the automotive industry. The gases are inferior in call of energy content per unit volume. Electric power may be stored on board a fomite in a battery or (for a improvident time) in capacitors. However, batteries are regarded within the automotive industry as substandard compared to liquid fuels in terms of energy stored by unit weight and volume.Furthermore their cost is high, and the manufacture of somewhat battery types involves macro quantities of scarce or environmentally-threatening materials including cadmium, lead, lithium, nickel, sodium, sulphur and zinc. According to the already mentioned just-auto report entitled The future of road vehicle fuels forecasts to 2020 (January 2008), the International Energy Agencys World Energy Outlook 2007 found that around 230m place of oil equivalent are required to meet global dema nd each day.Of this total, liquids account for the largest parcel of land of the 230m barrels (37%) followed by coal (23%) and natural gas (21%), leaving a 19% contribution from thermonuclear and sustainable sources. Of the liquids, however, transport use accounts for more than half (51%), with the remainder going to industry (32%), residential and moneymaking(prenominal) (11%) and power generation (6%).The residential and commercial share is mainly accounted for by oil-fired central heating, and the low-down power generation share by gas turbines running to meet peak loads. It follows that the transport vault of heaven share of the world energy market is just over half of 37%, in opposite words some 19% or just under one-fifth of the total. It should also be borne in mind that the transport sector is itself divided into light-duty vehicles (privately-owned passenger vehicles and light commercial vehicles), heavy-duty vehicles, and other transport applications (aircraft, ship s and diesel railway engines).The light-duty and heavy-duty sub-sectors take about 40% each, and the other applications some 20%. The search for improved efficiency in the transport sector must therefore press both light-duty and heavy-duty road vehicles.
