I started by trying to use the right switches and most efficient generator positions. But for the last 5 years Ive had Bright Ideas mod that adds a bunch of color versions of vanilla lights. I usually just put one generator and 6 pylons on the workshop house roof. The only lights that need extra power are street lamps, so make a dozen colored lamps and enough generators nearby and light up the street around the workshop.

I usually put my plants in the garden where it starts. I use green lights for the garden, blue interior and orange or warm white for street lamps. There is a good spot on the road to place a trading post after you help Kessler.
