Feeling better can start at home

How we heat and power our homes can affect how we feel each day. Warm, energy-efficient homes can support better health, greater comfort and lower stress from energy bills. Whether you rent or own your home, even small changes can make a difference.

Lightbulbs

Replacing 10 traditional lightbulbs with LED lightbulbs might cost you around €20 but it could save you around €200 a year.

Standby

A modern TV left on standby uses around 10 W (watts of energy) per hour which costs you about €32 annually. If you also switch off a games console (approximately 12W/hour on standby) and a desktop computer with attachments (15W/hour), you could save over €75 a year.

Solar

If you’re a homeowner, installing a solar PV system could save you between €200 and €300 a year on your home's electricity bill.

Energy retrofit

A deep energy retrofit could save you 50% or more off your annual energy bill. That’s a saving of around €1,650 per year based on the average energy bill of an Irish household.

Why it matters

In Ireland, the average household uses around 17.15 MWh of energy each year, with heating and hot water making up more than 80% of that use.

 Poor insulation allows heat to escape and increases the amount of energy needed to keep homes warm, which increases costs.

 Energy-efficient homes are typically warmer, drier and more comfortable to live in.

 Using energy more efficiently and switching to cleaner sources helps reduce emissions.

What you can do

To become more energy efficient at home you don’t need to make huge changes. Getting into small energy efficient habits can reduce your energy waste, improve your comfort and save you money.

Whether it’s something you can do today or a larger upgrade in the future, every change can help.

Small changes:

Simple everyday habits can help reduce your energy use while keeping your home comfortable.

 Turn down the thermostat slightly - reducing your heating temperature by just one degree can cut energy use while still keeping your home comfortable. Learn about the average electricity and gas bill in Ireland.

 Switch appliances fully off - electronics left on standby still consume electricity. Switching them off fully reduces unnecessary energy use. Get energy saving tips for your home.

 Use appliances efficiently - running washing machines and dishwashers on full loads at lower temperatures can reduce electricity use. How to save energy when using your washing machine.

Medium changes:

Improvements around the home can make a difference to energy use and comfort.

 Improve insulation - insulating your attic and sealing draughts can help keep heat inside your home. It also improves your comfort and saves you on energy bills. Upgrading your insulation, windows and doors.

 Upgrade your windows or doors -replacing older windows or poorly sealed doors can greatly cut down on heat loss.

 Get advice through a Sustainable Energy Community - local groups can help you access guidance, grants and support for improving your home energy efficiency. Find a local sustainable energy community.
