At our current rate of emissions, how long would it take to emit a quantity equal to the present mass of CO2 in the atmosphereAccording to the Energy Information Administration, Dept, of Energy, which country produced the largest amount of CO2 emissions from the burning of fossil fuels, in Gt in 2006?
- Which of the following statements is incorrect? An energy budget can be based on historical data, although this is usually unsatisfactory There is no standard formula for to calculate electricity costs The electricity consumption of air-conditioning can comprise of 80%-90% of the load of a building Economic cycle operation refers to the use of favourable environmental conditionsIt has been suggested that carbon dioxide emissions should be taxed at $30 per metric ton (106 g C). Removal of CO2 from the atmosphere would be worth the same amount. Assume that the atmospheric mixing ratio of CO2 is 400 ppm.
