Cold Weather and Energy Usage

The colder it is outside, the more energy it takes to heat your home. This often results in higher heating costs, as your heating system has to work harder, and kick in more often, to keep your home at a consistently comfortable temperature.

Energy efficiency

Heating makes up half the energy bill in most Nova Scotian homes, making it the single largest use of energy for most of us. But we can all find ways to heat our homes more efficiently.

Managing thermostats


Turning down your thermostat is one of the easiest and most economical ways to control your energy costs. The lower the temperature is set for heating, the more energy you save and the lower your costs. Try these tips to create a comfortable environment in your home and reduce your energy costs:

  • Set your thermostats at 21° C (70° F) (for heating) - this is the optimal temperature for comfort and energy efficiency.
  • Set your thermostats back for heating overnight or when you're not home. It doesn't take more money to heat your home back up and you can save as much as 10 per cent on your annual energy bill.
  • If you don't want to remember to raise or lower your thermostats, try a setback or programmable thermostat — it will do the work for you automatically.
  • Check, clean and calibrate your thermostat periodically to ensure it is accurate and working well.
