Training urban bus drivers to promote smart driving: A note on a Greek eco-driving pilot program

Economical, ecological and safe driving (eco-driving) is aimed at reducing fuel consumption, greenhouse gas emissions and accidents. Eco-driving is concerned about driving in a way compatible with modern engine technology: smart, smooth and safe techniques that lead to potential fuel savings of 10-15%. The Centre for Renewable Energy Sources of Greece conducted an eco-driving pilot study in collaboration with the Organization of Urban Transportation of Athens, and the Thermo-Bus Company to assess the effects of changing urban bus drivers\u27 driving style. Results showed an overall 4.35% reduction in fuel consumption per km as a result of the training

Energy audit in Athens metro stations for identifying energy consumption profiles of stationary loads

Metro transportation systems are significant energy consumers. Apart from the traction system, considerable amounts of electricity are consumed in metro stations. In the present study, energy audits of two Athens metro stations were conducted to ensure a detailed overview of energy consumption per stationary load. Data from on-site surveys as well as real-time measurements were elaborated. The energy profile over time was developed for the measured electrical loads. Results have shown that the total energy consumption of Sepolia and Peristeri stations was 117.09 and 99.17 kWh/m2/year respectively, as well as 0.12 and 0.52 kWh/passenger/year. Lighting and small power were significant consumers (23.3% of total energy consumed in Sepolia station, 51.5% in Peristeri station). The natural, piston effect induced ventilation system in Peristeri station showed significantly lower energy consumption (7.4%) than that of Sepolia station (25.9%) using forced ventilation for stations and tunnels
