This question is meant to give a sense of the type of action required to stabilize carbon emissions. The US emitted 6.67 GtC02e in 2018. 28.2% of that came from the transportation sector and 26.9% from the electricity sector. a) Additionally, in 2018, the US generated about 4,000 billion kWh of electricity. There were approximately 327 million people in the US. Assuming that two, 43-watt light bulbs, which typically run for 9 hours per day year-round, are replaced with two, 5watt LEDs for each person in the US, what are the resulting annual GHG emission savings in GtCOZe? b) In 2018, there were 280 million light-duty vehicles (LDVs) on the road in the U.S. On average, each of those vehicles traveled roughly 13 400 miles per year. The fuel economy of the on-road eet in 2018 was 25.1 per gallon (mpg). C02 emissions averaged 353 grams per mile in 2018. The US government has set a target of 54.5 mpg for the fuel economy of LDVs by 2025. How many GTCO2e would have been reduced per year if 1/4 the US LDV eet had met the 54.5 mpg target in 2018, and if CO2 per gallon and annual miles travelled remained constant
