I think that must be something like imparted kinetic energy rather than chemical energy of the fuel it burned. This puts Apollo 16 fuel at 4.19E13 joules: https://space.stackexchange.com/questions/35155/what-rocket-system-launch-contained-the-highest-amount-of-propellent-potential-e https://space.stackexchange.com/questions/35155/what-rocket-... Still doable with renewables though. Assume 11639 MWh of fuel energy and 60% efficiency converting electricity to fuel. About 19,400 MWh total. That's 8 days of output from a 300 MW wind farm operating at 1/3 capacity factor.
