Part 5: Technical Series on Energy Efficiency
Media Release: Part 5: Technical Series on Energy Efficiency
Issued George Municipality, 29th July 2019
George Municipality this week hosts the “ World of Tomorrow Festival 2019” - a drama competition for primary and high schools which culminates in a Gala Evening on Friday at the George Arts Theatre. Between 16h30 and 18h00, GridCars will be displaying the BMWi3, a fully electric vehicle that accelerates from 0 to 100 km/h in 7.3 seconds, without interruption. The electric engine of the BMW i3 with a performance of 125 kW and a torque of 250 Nm provides emission-free driving for up to 200 km.
Mphielo Ramotsamai is our final writer in this series. She has a National Diploma In Electrical Engineering and is working as an intern at the George Electrotechnical Services, Planning Department.
Transport, including private cars, public transport and freight, is one of the biggest consumers of energy. In the 35 OECD (Organisation for Economic Co-operation and development) countries, energy accounts for two-thirds of total man-made greenhouse gas emissions and 80% of total CO2. In addressing Energy Efficiency, the impact that Electrical vehicles can have on the modern society must be considered.
Energy efficiency simply means achieving the same performance using less energy. Vehicles can move because they convert energy from fuel to energy of motion. Most vehicles are dependent on oil as it is their main energy source. It is impossible for any engine to be 100% efficient as some energy is continuously lost to generating heat. Electric vehicles [EV] are more efficient in converting energy into motion.
Other benefits of the electric vehicle in comparison to petrol or diesel is that they have a lower running cost and are cost effective in terms of maintenance with certain parts not needed for eg. fuel injection, starter motor and radiators. By choosing to drive EV cars we are reducing harmful air pollution and so improving our environment. Renewable energy can be used to charge EV cars with the installation of PV systems at home work place and public areas, greatly reducing our dependence on fossil fuels. The batteries used in electric vehicles are more advanced than conventional vehicles and are designed for a lifespan of 8 years, with technological advances constantly reducing the cost.
Gasoline cars can drive long distances because of gas stations and a longer fuel range. Once electrical charging stations become more readily available, the long distance range of electrical vehicles will increase, making it a viable option for all forms of transport, including freight.
