Energy Efficiency

Save money at home

Reducing energy consumption is not only important for individual households because it saves money and reduces electricity bills, but also for the environment as it has a direct and immediate impact on greenhouse gas emissions.

Enova Community is dedicated to responsible energy use – ensuring householders and their families understand the various ways they can implement energy saving strategies. 

To spread our Energy Efficiency message we participate in advocacy and public speaking engagements, attend community events, conduct workshops, train Energy Coaches, orchestrate energy efficiency audits and much more.

Energy saving tips

Reducing energy consumption is not only important for individual households because it reduces electricity bills, but also for the environment as it has a direct and immediate impact on greenhouse gas emissions.

energy efficiency tip for saving water by enova


Hot water is the largest component of electricity bills. At around 30 per cent of your energy use, it’s the number one thing to look at when you want to increase the energy efficiency of your home. 

The most obvious solution is to use less hot water. You can do this by taking shorter hot showers, washing your clothes in cold water or at least no hotter than 30 degrees and installing water efficient shower heads.
Other worthwhile ways to reduce hot water costs will take a little more planning.

Check that your solar hot water system is working properly. Leaks or broken pipes can significantly impact the hot water component of your bill.
The next time you have an electrician or plumber come to your house, ask them to turn the temperature on your hot water thermostat down to 60 – 65 degrees*.   

Consider the benefits of installing a solar hot water system. Removing hot water heating costs from your electricity bill will make a noticeable difference.
For those homes with solar hot water, only turn on your hot water booster when needed – that is when you notice that your hot water temperature is starting to drop below acceptable. Keeping your booster on when your water is being heated by the sun means you are drawing power from the grid when you don’t need to.

heating and cooling tips from enova

Heating and Cooling

Using an air conditioner or heater is a large energy expense. There are many ways you can reduce aircon use and minimize their impact on your bill.

Only heat or cool the room you are using and keep doors and windows closed when the air conditioning is running.

Turn your temperature control to 18 – 20 degrees in winter and 24 – 26 degrees in summer. Each one degree difference increases energy usage by around ten per cent (results may vary). 

Use ceiling fans instead of air-conditioning in summer. Even if you do use air-conditioning sometimes, you can limit its use (and its impact on your electricity bill) using your fans instead, once your room has cooled down. Ceiling fans cost about five cents an hour to run. Much less than an air conditioner. 

Replace old air conditioning units with energy efficient, reverse cycle air conditioning.

And of course, before turning on any heating or cooling appliance, try putting extra clothes on if you are cold and take some off if you are hot!
shade and ventilation to reduce energy costs

Shade and Ventilation

The need to use air conditioners and heaters can be further reduced by taking a conscious approach to how you shade and ventilate your home. 

By using fans and natural ventilation where possible you can keep inside spaces cooler.

By sealing any draughts and putting up curtains to trap night-time heat in winter you can reduce the need for heating in winter.

Adding external shading such as strategically placed shade plants and awnings can limit hot westerly afternoon sun from entering the house. Trimming shade trees in winter allows that winter sun in. 

Adding window coverings such as drapes or roller blinds can decrease the temperature in a room by up to 3 degrees in summer (results may vary). Close your blinds to keep daytime summer heat out and open blinds and doors on summer nights for cool ventilation. 

Consider the air ventilation through your house. Can you open front and back windows during the cooler parts of the day and in the evening, to allow fresh air to flow through and cool your home?
lighting efficiently to save energy


Replace incandescent and halogen light bulbs with light emitting diodes (LEDs) or compact fluorescent lamps (CFLs). 

By updating to LED lights, you could save up to 93% every year* on the lighting portion of your energy bill. LED lights are the most energy efficient and longest lasting lights available and they do not contain any mercury, harmful gasses or toxins.

standy by power to save energy

Standby Power

Turn off electrical appliances at the wall when not using rather than leaving them on stand-by. You could save additional dollars per year on your electricity bill simply by cutting out standby power usage and reduce your impact on climate change at the same time.
insulation to save power


Insulate ceilings, walls and floors where possible. Floor rugs and window blinds and curtains can do a lot to insulate your space too, keeping the air inside warmer or cooler for longer.
using pool pumps in an effcient way

Pool Pumps

Your pool pump can be a considerable drain on your energy usage. Reduce its impact by considering upgrading to a variable speed drive pump. This newer technology will pay for itself. Set on low speed, energy use is greatly reduced. High speed setting is only needed if vacuuming the pool (to pick up leaves etc).
Households with solar should run their pool pump while the solar system is generating energy during the day. 

If you don’t have solar, try running your pool pump in off peak times to reduce your energy costs.
