The Delaware Division of Energy and Climate is offering tips to help residents use less energy and save more money this summer.

The following tips include:

Auto:

- 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.

Home:

- 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.

Appliances:

- 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 the 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.
