Another example of human ecosystem open to what others are doing and adapt
A new study by New York University and Yale professors suggests that rooftop solar is contagious. You are more likely to install solar panels on your roof if your neighbors have gone solar.
“We found that there is a positive, statistically significant, causal effect of previous nearby installations on a household’s decision to adopt solar panels,” said Bollinger. “A one percent increase in the zip code installed base leads to approximately a one percent increase in the zip code adoption rate.”
