Public transport in Europe has excellent environmental credentials and important progress has been made in increasing efficiency and reducing energy consumption in the last years. Bus fleets, for example, have been at the forefront of testing alternative fuels for years and the electrification of public transport ranges from 40 to 50%, while some conutries even reach 66% (Germany) due to large tram, light rail, metro and trolleybus systems.
Further electrification of public transport in combination with green electricity production may further improve this situation. Investments in electrifying public transport have a particularly high impact since public transport vehicles have extremely long operating hours, e.g. 16 hours per day for urban buses, compared with less than one hour per day for conventional cars. A single 18m urban bus consumes annually about 40,000 litres Diesel - equivalent to more than 100 tons CO2!
