Electricity for New Yorkers is more likely to fail in June, July and August, especially when the temperature rises above 68 degrees.

Many of the calls reporting power failure were in areas with “high energy burdens, lower-income households, and high percentages of people of color. Furthermore, we found the higher call areas were associated with higher vulnerability to heat-exacerbated deaths.”

These findings are in an article in Sustainable Cities and Society, which warned that NYC blackouts will become more frequent and last longer as demand for electricity grows.

Customers can minimize their individual demands by switching to energy-efficient air conditioners, which also put less stress on the environment.
