Cost Comparison: EV vs. Petrol and Diesel Vehicles
1. Electric Vehicle (EV) Costs
• Efficiency: 3 miles per kWh
• Total Energy Required: 10,000 miles ÷ 3 miles/kWh = 3,333.33 kWh
• Charging Cost (Octopus Go Tariff @ 7p/kWh): 3,333.33 kWh × £0.07 = £233.33
2. Petrol Vehicle Costs
• Average Fuel Efficiency: 40 miles per gallon (mpg)
• Total Fuel Required: 10,000 miles ÷ 40 mpg = 250 gallons
• Convert to Litres: 250 gallons × 4.546 = 1,136.52 litres
• Fuel Cost (@ £1.3946 per litre): 1,136.52 litres × £1.3946 = £1,585.95
3. Diesel Vehicle Costs
• Average Fuel Efficiency: 50 mpg
• Total Fuel Required: 10,000 miles ÷ 50 mpg = 200 gallons
