I've got my sims educated as much as they can (grade school through to university), I've saved up enough, put down an NPP and nobody wants to work at the plant, the land value/happiness nosedives (which I can understand), but as soon as I take the plant away the happiness goes back up, but if I look on the overall screen it's the opposite effect, the happiness goes up overall when the plant's there.
What am I doing wrong? I specifically zoned a residential/commercial area around the plant (which btw has all the upgrades), for the workers, yet people move in and don't want to work at it, they all flock to my solar plant on the other side of the city.
Any ideas?
Simcity is "famous" for it's green outlook. So your inhabitants will prefer green energy and workplaces. Thus going to the solar plant first.
Consider researching the improved solar panel. With that and a very small, also researched, windmill plant i can power my entire city _and_ the regional archeology. With power to spare.
