How do I stop the fines for "excessive" energy use?

I finally read up on the Eco pack and learned how all that stuff worked. Ended up planting 15 wind turbines around the lot and then finally the household was generating a surplus of energy each month so I didn't have to repeal the N.A.P. after all. Just don't get sucked into the wind turbines. Also, why don't they give us the option of upgrading them so they don't break down so often. At least when your sim fixes them over and over they get faster at it and doesn't take up so much of their day. And you get lots of "bits and pieces" from the scrap that the fixings generate.
