The ideal thermostat setting for summer is generally 78°F (26°C) when you're at home and potentially 82°F (28°C) or higher when you're away or sleeping. This helps balance comfort with energy conservation. 

Here's a more detailed breakdown:

78°F (26°C) while at home:

This is the recommended starting point by the U.S. Department of Energy for optimal energy savings while maintaining a comfortable indoor temperature. 

Slightly warmer temperatures (82°F or higher) when away or sleeping:

Increasing the thermostat setting by a few degrees when you're not home or when you're asleep can lead to significant energy savings without sacrificing comfort too much. 

Consider personal preferences and local conditions:

Some individuals may find 78°F too warm and may prefer a slightly lower temperature, while others may be comfortable with it. Adjust the temperature to your comfort level while still aiming for energy efficiency.

Use fans to supplement cooling:

Ceiling fans can help circulate air and make a room feel cooler, allowing you to raise the thermostat setting without feeling uncomfortable.

Close blinds and curtains:

Blocking direct sunlight can help reduce the amount of heat entering your home, making it easier to maintain a comfortable temperature with a higher thermostat setting.

Limit heat-generating appliances:

Avoid using appliances like ovens and stoves during the hottest parts of the day, as they can contribute to a warmer indoor environment. 

By following these guidelines, you can enjoy a comfortable home environment while also reducing your energy consumption and saving money on your electricity bill.
