NV Energy is asking you to conserve electricity this evening due to excessive heat in both Nevada and California. Customers are especially being asked to conserve between the hours of 5 p.m. and 8 p.m. That means turn off unnecessary lights and reduce the use of your air conditioning, dryers, dishwashers, and other household electronics. NV Energy says it has enough supply to fully power homes, but says limiting your use can help during peak demand.
