Thanks for giving it a try!
For the workers, you have to add houses (those are the gray buildings), which need to be placed near a wind turbine.

Ah I get it now. Great idea, I think with a few adjustments this could be a banger game for guitar hero inclined folks. I found the best sounding key (space) not that often used, so that was a bummer. Also, some variation would help, although at the end I got kinda good at the rythm I had built up (missing a ton of keys though because the city got big). Good stuff!
