Renault’s top five eco driving tips

We’re proud to be in partnership with Renault, Europe’s leading electric vehicle manufacturer. We’re using a range of their amazing 100 per cent electric vehicles, which are perfect for doing all sorts of jobs at Eden and also help us to make our daily operations as green as possible. Find out how you can take easy steps to green your own driving at home.

1. Share lifts

If half of UK motorists shared a lift just one day a week, pollution would be reduced by 10% and traffic jams by 20%. Plus they’d have someone to chat to!

  • If people travelling to work shared lifts, they can save £1000 per year on average. 
  • It’s not just fuel you save (petrol and diesel prices have gone up 74% in 10 years). You’ll be using less of other things like brakes, oil and filters too.
  • Sharing is caring. People who share lifts to work can reduce their stress before starting the day.

2. Check your tyres

Car tyres are filled with air, which makes them squishy and more comfortable. But if there’s not enough air inside the tyres, your car will use more fuel, because the tyre is harder to rotate. So you can help the environment by making sure you have the correct tyre pressure.

  • As well as energy consumption, tyre pressure affects many things, like braking distance, grip in corners and comfort. 
  • Under-inflated tyres also wear out more quickly, because more rubber is in contact with the road.
  • Under-inflated tyres can increase your fuel consumption by around 5%.
  • Renault ZOE’s tyres are made by Michelin, and are specifically designed to use less energy, and they are quieter!

3. Lighten your load

Cars like Renault ZOE have useful space in the boot and inside the car, but many of us carry around unnecessary things we don’t need. Every gram helps when it comes to saving weight, and less weight equals less energy required to move the car. 

  • Nearly a quarter (22%) of UK drivers use the boot of their car as a permanent storage space.
  • The top five boot items in Britain are: tools (43%); wellies and clothing (27%); sports equipment (11%); pushchair/baby equipment (9%) and shoes (9%).
  • Every 50kg (roughly the weight of a teenager) needs 1-2% more energy to move the car.
  • If you drive a petrol or diesel car, it weighs more with a full tank. Electric vehicles like Renault ZOE weigh the same regardless of how full the battery is.

4. Go steady

When you drive a car, the most energy is used getting up to speed (accelerating). Maintaining that speed is actually quite easy. So the more time you spend at the same speed, the less fuel you will use. When you need to brake, regain your speed gently and smoothly to use less energy.

  • In cars where you change gear yourself, driving in a higher gear will use less fuel. Turning the steering wheel forces the tyres to scrub sideways slightly, which reduces your speed. So be super smooth with the steering wheel to use less fuel.
  • Torque is the twisting force that turns the wheels on a car. 
  • Electric cars like Renault ZOE generate huge torque, which helps get up to speed with less energy.
  • If you’re able to cut your fuel consumption by 30% then that can save the equivalent of 0.9 tonnes of CO2 per year – about the same as 41 trees!

5. Braaaaaake

Brakes are fabulous things. Eight little pads (each only the size of a mobile phone) squeeze the brake disc, just like the brakes on a bike. But there’s another way to slow a car down, using a technique called ‘engine braking’. Electric cars also use engine braking but in a slightly different way.

  • In a petrol or diesel car, slow down by going down through the gears: 5th – 4th – 3rd – 2nd – 1st. This reduces fuel consumption!
  • Renault ZOE has two different ways to slow down: electric motor deceleration and regenerative braking. They work together. 
  • When you want to slow down, motor deceleration means that instead of the motor turning the wheels, the wheels turn the motor. This creates kinetic energy to charge the battery.
  • Regenerative braking uses normal disc brakes (like a petrol car), but the energy from the brakes is turned into electricity. This charges the battery again! Win/win!
