Hot Desert

After enduring the warmest March on record and even hotter weather in April, Tucson residents now face a forecast for above-average temperatures in May, according to the National Weather Service.

Amid such warm weather, Tucson Electric Power is encouraging customers to get an early start on energy saving strategies that will help take the heat off their summertime electric bills.

Think About Your Thermostat

As outdoor temperatures increase, a home cooling system must use more energy as it works harder to maintain the same indoor temperature, even if the thermostat is left at one setting all the time. High humidity can further increase energy usage because air conditioning systems must remove more moisture from the air and evaporative coolers work less efficiently.

To minimize cooling costs, set thermostats at the highest comfortable temperature. The U.S. Department of Energy recommends setting thermostats at 78 degrees in the summer, although individual preferences may vary. For every degree you raise your thermostat, you can reduce your overall energy costs by about 2-3 percent.

Customers also might consider installing a Nest Learning Thermostat, which can learn users’ temperature preferences and automatically adjust to save an average of 15 percent on cooling bills, according to the manufacturer. TEP offers $50 rebates to residential customers who purchase these thermostats.

Use Easy, Proven Ways to Save

 Following these simple tips may help to reduce energy usage:

  • Use ceiling or oscillating fans to keep air moving so you feel cooler without increasing air conditioner use.
  • Don’t block vents or ducts inside the house. Maintaining clear air paths allows your cooling system to work more efficiently. Keep exterior doors and windows closed when running the air conditioner.
  • Use shades, blinds or curtains to keep sunlight out, especially during the afternoon in rooms facing west.
  • Replace traditional incandescent light bulbs with ENERGY STAR-qualified light-emitting diode (LED) bulbs, which emit 90 percent less heat than regular incandescent bulbs. Over the course of its lifetime, an LED bulb will save an average of $80 in energy costs.

New appliances, changes in lifestyle or equipment in need of maintenance can all contribute to increased usage, especially during warm weather when customers usually use more energy. Pool pumps, clothes dryers and other appliances can offer energy efficient features that can help to reduce energy usage.
