- Transport Energy Conservation
- Bulk Transport
- Smaller numbers of larger vehicles
- Type of Transport
- Slower transport more energy efficient e.g. rain wagon, canal barge
- Vehicle Design
- Air resistance - smoother the cars passage through air, less energy lost as friction
- Regenerative braking - hybrid cars slowed down with generator, creating electricity
- Useful for urban stop-start driving
- Vehicle weight - lighter = less energy needed to move it
- Plastics instead of metal
- High strength steel so use of thinner lighter sheets
- Aluminium engine blocks
- Careful wiring - shorter and lighter cables
- Wheel design - solid tyres produce less friction but more bumpy
- Fuel combustion efficiency - engines don't burn all their fuel
- More valves per cylinder - efficient waste gas removal
- Thermostatically operated fan to maintain optimum engine temperature
- Ignition control - accurate ignition spark timining
- Mode of Vehicle Use
- Traffic management to reduce congestion - allows cars to drive at optimum speed
- Bulk Transport
