DNREC Division of Energy and Climate offers tips
to beat the heat – and the high cost of cooling 

DOVER (June 29, 2019) – It’s summer in Delaware. The heat is on, and the humidity is steaming. You’d like to stay cool, but that means using more gas in your car and more power in your home – and leaving less money in your pocket. To tip that balance in your favor, the DNREC Division of Energy and Climate offers the following tips to help you use less energy and save more money this summer.


·         For fuel economy, use your air conditioner only when absolutely necessary – and set the temperature higher and the blower lower for comfort.

·         Park in the shade when possible and leave windows open slightly to reduce the “oven” effect.

·         To help overall air quality, fuel up when outdoor temperatures are coolest, usually early morning or evening after sunset.

·         To save gas (and time), plan those Saturday errands in a circular route starting and ending at home instead of traveling in random directions or making several trips. 


·         To save energy, set thermostat/air conditioner temperatures higher during the day when no one is home.

·         Adding a programmable thermostat to your home’s HVAC system will allow you to set day and night temperatures automatically.

·         If you have windows open instead of air conditioning, close them to a crack and pull shades or curtains during the day to help keep the heat out.

·         Open windows at night and use fans to help circulate cooler night air.

·         Ceiling fans are a great addition to circulate air and keep cool, with or without AC.

·         Replace that wheezing old window air conditioner with a more efficient energy-saving unit.


·         To reduce heat sources as well as energy usage inside your home, turn off or unplug any appliances or electronic devices (such as computers) when they are not in use.

·         Plan meals around minimal use of your stove, especially the oven. (Think cool salads, cooking on an outdoor grill, etc.)

·         If you have a clothesline, hang out at least some of your laundry to minimize heat from clothes dryer use. (A clothesline also saves energy costs any time of year!)

·         If purchasing new or replacing older appliances, such as air conditioners, refrigerators, etc., look for the Energy Star rating!
