Summer Energy Conservation You Can Do at Home

During the summer, people tend to leave their air conditioners and fans on for long periods, which consumes a lot of electricity. Here are some summertime energy-saving techniques that will help you maintain an environment- and budget-friendly lifestyle.

Thermostat and Environment: Tips on Using Air Conditioners

People often use their air conditioners for more than half the daytime in summer, using up great amounts of energy. You can conserve energy and avoid heatstroke as well by doing such things as not turning your air conditioner on and off too frequently and not placing items near the outdoor unit.

Cut Down on the Heat Coming Indoors

Seventy percent or more of the heat that enters a room comes through the windows. Blocking measures such as curtains and blinds—as well as growing “green curtains” of plants outside that stop the sunlight—are effective ways of keeping your home cool.

Adjust Your Thermostats to Suit the Season and Time of Day

● During the summer, turn off your toilet seat warmer and set the temperature of the cleansing water to its lowest setting.
● Turn off the lights during the day, and use only the minimum light needed at night.
● Choose the “medium” setting in your refrigerator during the summer and the “low” setting during spring, autumn and winter.
● Lower the brightness of your TV screen or use the set’s energy conservation mode.
