The Answer is 1 bbl of crude oil has the energy content

6.12 imes 10 ^ { 9 } \mathrm {~J} ext {, so } 50 \mathrm { bbl } ext { contains }

50 imes \left( 6.12 imes 10 ^ { 9 } \mathrm {~J} ight) = 3.06 imes 10 ^ { 11 } \mathrm {~J}

The average power over the year is

\left( 3.06 imes 10 ^ { 11 } \mathrm {~J} / \mathrm { y } ight) / \left( 3.15 imes 10 ^ { 7 } \mathrm {~s} / \mathrm { y } ight) = 9.71 \mathrm {~kW}
