Energy saving tips during a heat wave, other than adjusting the AC

As summer heat bears down on the region, utility companies are urging New Jersey residents to cut energy use. But there are ways to do so beyond simply turning down the air conditioning.

Consolidated Edison and PSE&G have released updated guidance on how to reduce electricity consumption and save on monthly bills as demand spikes during hot weather.

One of the most effective steps is keeping sunlight out. Con Edison says that about 40% of unwanted heat in homes comes through windows. The company recommends drawing blinds, curtains and shades during the day to keep indoor temperatures lower.

Another overlooked drain on energy is the clothes dryer. “Hang laundry to dry,” Con Edison advises. “A typical clothes dryer uses up to four times more energy than a clothes washer.”

The company also warns of “vampire voltage” — electricity drawn by devices even when they’re switched off. To combat this, residents are encouraged to unplug chargers, televisions and gaming systems when they're not in use.

Computers can also be set to sleep mode after 20 minutes of inactivity to save energy. Refrigerators should be kept at 38 degrees Fahrenheit and their coils should be cleaned annually for maximum efficiency. Con Edison also notes that switching from baths to showers can cut water heating costs, since showers typically use half as much water.

PSE&G adds that ceiling fans set to spin counterclockwise in the summer can help circulate cool air more effectively. The utility also suggests raising thermostats when no one is home, replacing air filters monthly, and operating dishwashers and laundry machines in the early morning or late evening to avoid peak usage hours.

Both utilities say that small changes in daily habits can help relieve strain on the power grid and lower utility bills
