I think your calculations must be out.

The work achieved (lifting some tons of rocket) is orders of magnitude less work than the power extracted from falling water (hydro, thousands of tons per second).

And the heat output of burning hydrocarbons and nuclear reactions worldwide were concentrated into a few rocket nozzles, that would be rather mind boggling!

For the record, the saturn V rockets operated at 120GW. Which is also close to a terawatt.

Read the two comments (one I replied to and the one it relied to) for context. My comment wasn’t intended to be free standing on its own.
