Jobs for 500 people vs cheaper electricity for 1 million people which allows them to spend more money elsewhere and thus also creates jobs. The second option might seem roughly equal, except those new jobs are creating value and thus society is better off with increased efficiency.

Of course those benefits aren’t spread equally, but being poor today is still better than being poor 500 years ago. Hopefully being poor in 500 years will be a similar improvement.

Actually it applies even more, because renewables are decentralised and small scale, so there's a wide range of jobs from house-level local installations to international infrastructure.
