1. According to the EIA, how much did all the customers in the US pay for electricity in 2018, in billions of USD?

2 - According to the LLNL 2018 Sankey Diagram, how much natural gas was used by the Residential Sector in 2018, in EJ?

3 - According to the EIA, how much did the Residential Sector pay on average for natural gas in 2018, in dollars per gigajoule? Use the real (inflation-adjusted price).

4 - Given the amount of natural gas used by the Residential Sector and the average price paid, what was the total amount that the Residential Sector paid (in billions of dollars) for natural gas in the US in 2018?

4.1 - Please repeat the same process above for the cost of natural gas to the Commercial and Industrial Sector. How much did the US Commercial Sector pay for gas in 2018? Use the LLNL Sankey Diagram for gas consumption, and the EIA for commercial gas prices.

5 - Given that price and the total consumption of petroleum by the Transportation Sector (from the LLNL Sankey Diagram), how much did the transportation sector pay for petroleum in total in 2018?

6 - Finally, how much did the Industrial Sector pay for petroleum in 2018? For simplicity, you can assume that this sector pays the average price of oil in the US. For the price of oil, you can use the EIA’s "average price of imported oil." For petroleum consumption, use the LLNL Sankey Diagram.
