Question

Brightfuture elected a new mayor in 20 he wants to switch municipal buses from diesel to electricity. 18 who is even more environmentally progressive than the previous mayor. Currently the fleet consists of 200 buses with the following attributes: Average mileage of diesel buses: 3 mile/gallon Cost of diesel $3 gallon The electric buses are 5 times $0.10 /kwh. Each bus does about electric buses cost half as er unit of energy. Cost of electricity to the town 40,000 miles a year. The diesel buses cost $20,000 a year per bus in maintenance cost while the eie much per year per bus. The electric buses each cost $550,000 A What is the annual operating cost per bus for the diesel buses? What about for the electric buses per bus B. How much CO2 does a diesel bus contribute annually? C How much CO2 is an electric bus responsible annually if its energy is derived from an electric souce with the following mix ANatural gas with a turbine efficiency of 65% 25% from coal-fired plant with an efficiency of 35 power? 50 and 25% from nuclear Pounds of CO2 emitted per million British thermal units (Btu) of energy for various fuels Coal 220 lb , Natural gas 117 lb Diesel 22.38 lb per gallon. Energy content: Natural gas: 1050 BTU per cubic ft. Coal 19.78 x106 BTU per 2,000 lb and Diesel D. Nitrogen oxide compounds (NOx) are a pollutant that has a regional environmental impact, including acid rain and human health impacts. What is the total annual output of NOx in pounds by the diesel fleet? NOx lb/gallon of diesel 0.4 lb/gal. sulfur oxide compounds SOx mercury and particulate pollution is major concern with coal-fired power plants Coal on average contains about 1.3% SOx by weight 85% of it is removed by scrubbers that have been installed in coal-fired power plant smoke stacks. How many pounds of SOx is going to be emitted from electrical usage by the buses assuming the power distribution from above (50% from coal)?
