Energy Conservation

What La Mesa is Doing
The city is committed to doing our part to reduce energy consumption such as lighting retrofits and reduction of non-essential overhead lights used in city facilities. Since traffic signals use about 30 percent of La Mesa’s total electricity consumption, the city has already converted most of its red and green incandescent lights to LED - leading to an estimated 50 percent cost savings.

Ten Ways to Save Energy & Money
Here are ten ways that you can save energy and your pocketbook throughout the year.
  • Keep your thermostat low and use fans. 78º when you’re home and 85º when you’re away. Using fans instead of A/C can save as much as $1.25 an hour.
  • Switch to fluorescent lighting and switch off lighting. Switch to efficient compact fluorescent lights (CFLs) but don’t forget just to turn them off when not needed.
  • Turn off electronics when not in use. Screen savers on computers do not save energy, only the “sleep mode” does that.
  • Use major appliances after 7:00 pm. More energy is available after hours.
  • Unplug unused appliances. All plugged-in items drain electricity even when turned off. Unplug devices that don’t need constant power, such as toasters, coffee makers, and phone chargers.
  • Close blinds and drapes. Do this during the hottest part of the day (afternoon) to help block out the sun’s heat.
  • Plant shade trees. Plant trees for shade along the west side of your house to help block the blazing afternoon sunlight.
  • Check your weather stripping and insulation. Up to 20 percent of your A/C and heat can be lost through ineffective insulation.
  • Wash only full loads of laundry and dishes. Use cold water since 90 percent of the energy is used to heat the water.
  • Turn down your water heater. Set its thermostat between 120º and 125º unless your dishwasher requires a higher setting.
