While improved transportation systems provide economic benefits, there may be some associated environmental costs. What are the major environmental costs associated with transportation and what are their potential negative impacts?

A6 In 2-3 paragraphs, please answer the following question from your textbook: While improved transportation systems provide economic benefits, there may be some associated environmental costs. What are the major environmental costs associated with transport systems and what are their potential negative impacts?

Are electric cars a more sustainable method of transport than diesel or petrol powered cars? In this Case Study, I explored whether electric cars are as eco-friendly as they claim to be, providing a sustainable method of transport that could significantly reduce our carbon footprints if we all ditched the convectional vehicles, and changed to electric cars. I found many arguments both for and against electric cars. Electric cars are powered by an electric motor which draws its power from an on-board battery pack which acts as an energy store for the car. Energy is measured in joules. A joule is a very small amount of energy so a domestic electricity metre measures the energy in kilowatt hours. Stoical Energy Transferred = Power x Time (Joules, J) (Watts, W) (Seconds, S) (Kilowatt hours kWh) (Kilowatts, kW) (Hours, H) Source; GCSE Core Science revision guide (Information collected from GCSE Science revision guide 13:26hours) Batteries are charged by simply connecting the vehicle to a…
