1. Calculate the mass of oil needed to power a 100Watt lightbulb for 1hour (efficiency is 35%). 2. Calculate the mass of uranium needed for a 1GW power station each year. 3. Calculate the mass of Coal burned in the world each year. By what proportion does this increase the concentration of CO2 in the atmosphere (currently 3000Gigatonnes)?
