The Eco Travel Network (ETN) is about reducing the amount of energy we use to move ourselves around. This will be necessary as energy prices increase, but it doesn’t have to be worthy and dull.
Scientists measure energy in joules, but most of us are more familiar with the kiloWatt-hour (kWh) which is how energy is measured on our electricity and gas bills. A kWh costs an average of 14p if bought in the form of electricity in the UK today.
One kilowatt hour is the energy you need to:
- Boil about 10 litres of cold water.
- Drive an average UK petrol-powered car about 1 mile.
- Drive an ETN Twizy about 8 miles.
- Power an electric assist pedal bike for about 50 miles.
In Powys, we generate a lot of our electricity from wind, sun and rain. 95% of people's car trips and over 60% of their mileage could be done in a Twizy. But how much of our personal travel could we power from renewable resources? If we assume the Twizy averages 5000 miles in a year:
- The PV panels on one domestic property produce enough power (3000kWh) for 24,000 Twizy miles, or nearly 6 Twizys worth.
- The community hydro-electric turbine at Talybont Reservoir produces enough power (250,000kWH) for 2 million Twizy miles a year. That’s enough for 400 Twizys, or every 2-car household in the Talybont community council area.
- A single 2 MW wind turbine produces enough energy (5000MWh) for 40 million Twizy miles in a year. That’s enough for 8,000 Twizys.
