This is given from my notes:Power GenerationOil - 40% efficient; CO2 Emissions (g/mol) 70 g/molNatural gas - 23% efficient; CO2 Emissions (g/mol) 50g/molCoal - 23% efficient; CO2 Emissions (g/mol) 90 g/molEnergy Density of various sources (In heat of combustion -MJ/kg)Coal - 30 MJ/kgDiesel - 45 MJ/kgGasoline - 47 MJ/kgKeronsene - 46 MJ/kgNatural Gas - 39 MJ/kg @ STPWater - 10,000 J/m3Please Show all work and give as much details aspossible.Questions:
A coal power plant is 23% efficient. If it produces 50MW of power, how much energy does it actually consume persecond? Per hour? Per Day?
How much coal does it burn to do this (I think you need thetable I wrote at the top)
How much CO2 is produced per second? Per hour? Per day?
The effects of the spin of the earth
When burned, 3.7 tons of coal releases the amount of energy that you use over the course of a year in the form of heat. How many tons of coal are required to provide you with your yearly energy use if you were to get that energy from a coal burnin..
