Fuel Usage Of Electric Vehicles - 1389 Words

Introduction In 2015, transport energy demand in New Zealand was up 2305.56 GWh, the largest annual increase in 20 years (MBIE, 2016). This energy came from non-renewable fossil fuels, and as such is not sustainable in the long term. The subject of this research is to investigate the impact of targeting 20% of the light passenger fleet being electric. The current electric vehicle fleet is less than 1% of the light passenger fleet, which consists mainly of petrol and diesel vehicles (Ministry of Transport (MoT), 2016). If the New Zealand government hopes to increase this figure to 20%, one of the main driving factors is reducing fossil fuel consumption. At face value, electric vehicles are the solution to reducing fossil fuel usage in the†¦show more content†¦Vehicle fleet data (MoT, 2015) reveal that 29,249 million kilometres were travelled by 2,811,703 light passenger vehicles (LPV) on petrol. Hence, the average km travelled per LPV was:29,249 million kilometres2,811,703 LPV=10402.69 km/LPV The average light petrol fleet fuel economy in 2015 was 9.59 L(petrol)/100km (MoT, 2015). Thus, on average, each LPV used: 10402.69 km/LPV9.59 L(petrol)/100km =997.91 L(petrol)/LPV Hence, the total petrol consumed by 20% of vehicles in the LPF is: 997.91 L(petrol)/LPV603,624 LPV=602.36 million L(petrol) Consequently, this means that electric vehicles will save about 600 million litres per year if they replaced 20% of the LPF. Furthermore, in terms of CO2 emissions this equates to: 22.9619.59 L/100km10402.69 km/LPV603624 LPV=13,826,796.2 kgCO2 not emitted from petrol consumption per year. Total fossil fuel offset While electric vehicles do not directly burn fossil fuels, electricity production does. As a result, the total fossil fuel offset from electric vehicles is less than the fossil fuels burned when using petrol vehicles. A popular electric vehicle in NZ is the Nissan Leaf (MoT, 2017). The following calculations use the specifications of this car, which has an energy consumption rate of 18.7 kWh/100 km (US Department of Energy, 2017). For an electric vehicle (EV) to travel the same distance annually as a typical light passenger petrol vehicle, the amount of energy consumed is: 10402.69 km/EV18.7 kWh/100Show MoreRelatedInternal Combustion Engines And Its Effect On The Environment1324 Words   |  6 Pagesatmosphere, turns the planet into a green house and traps the temperature. Factories, electronic appliances used at home are sources of release of carbon particulates. However the primary source of carbon emissions has been motor vehicles that run on petroleum or diesel as fuel. Earlier the number of cars was less and the emission norms were not formed to control the excessive carbon emission. Today the number of cars has risen drastically. Even though the emission norms are strict and gave a set emissionRead MoreSearch for an Alternative Fuel Source for Automobiles1645 Words   |  7 PagesAlternative Fuel Source for Automobiles Since it’s invention and birth in 1886 automobiles have influenced the world in a huge way. It saved people a lot of energy, time and money. Motorized wagons replaced horse carriages and within a few decades Ford started making affordable models of cars with higher efficiency, which revolutionized the concept of transportation. The first ever car that was built was powered by steam. But with development in science and technology other efficient fuel sourcesRead MoreHybrid Vehicles Are Environmentally Friendly Vehicles1270 Words   |  6 PagesHybrid vehicles, which are environmentally friendly vehicles, which will replace fossil fueled car in the future but they have a limited range and long fueling time. As fossil fuel resources start to become limited and non-environmentally friendly, car manufacturers are looking to find ways to make hybrid vehicles the future of transportation. Hybrid vehicles are beneficial since they are efficient, reduce pollution, and cut global emiss ion than the current hybrids models. As such, hybrid-electricRead MoreTechnology Development Of The Automotive Industry And The Enhancement Of Fossil Fuel Alternatives1367 Words   |  6 Pagestechnology development in the automotive industry and the enhancement of fossil fuel alternatives. With countries advancing their energy output the strain on natural resources is increasing, leading to finite resources which will no longer be a viable option in the near future. Research has been conducted and other options have been found some of which include Plug-in electric vehicles (PHEVs) and other electric or bio fuel alternatives. In the recent years energy consumption has been reduced in compressionRead MoreExxonmobil: Social Responsibility in a Commodity Market Essay1048 Words   |  5 Pagestheir daily commutes, errands, and vacations. However the reality is that the price of fuel has implications much grater than most consumers realize. Fuel prices affect nearly everything we purchase. For example, the price of farm commodities and food increase because farmers pay more for the fuel for their farm equipment and trucking firms pay more for fuel to get the commodities to market. These shipping â€Å"fuel surcharges† impact all goods shipped by truck, and will raise retail prices over timeRead MoreHybrid Automobiles vs. Fuel-efficient Automobiles1283 Words   |  5 Pagespurchase a fuel-efficient automobile.
