Every year, millions of people across the globe take part in Earth Hour, a simple but powerful act of switching off lights for one hour.

It’s a symbolic moment. A shared pause. A reminder that small actions, when taken together, can have a global impact.

But what happens after the hour is over?

What is Earth Hour?

Earth Hour takes place annually at 8:30pm local time, when homes, businesses, and landmarks around the world switch off non-essential lights.

Started by the Worldwide Fund for Nature, it’s grown into one of the largest environmental movements globally, raising awareness of climate change and energy consumption.

And while switching off your lights for an hour won’t drastically cut emissions on its own, that’s not really the point.

It’s about awareness and what comes next.

Why one hour isn’t enough

Earth Hour is a powerful reminder of how energy connects us all. But the biggest impact doesn’t come from one hour in March — it comes from the choices we make every day in our homes.

Heating, hot water, insulation, and electricity use all add up over time.

So, while switching off your lights is a great place to start, the real opportunity lies in making changes that last all year round.

How your home can make a bigger impact

The good news? You don’t need to overhaul everything overnight. Small, practical changes can make a meaningful difference.

1. Improve your home’s insulation: A well-insulated home uses less energy to stay warm, reducing both carbon emissions and energy bills.

2. Be smarter with energy use: Simple habits like turning off unused appliances or adjusting your heating can reduce unnecessary consumption.

3. Upgrade how your home is heated: Traditional heating systems can be energy intensive. Alternatives like an air source heat pump use electricity to transfer heat, making them a more efficient, lower-carbon option for many homes.

Start with understanding your home

Every home is different. The best way to make meaningful changes is to start with a clear picture of how your home currently uses energy and where improvements can be made.

That’s where having a personalised plan makes all the difference.

From one hour to long-term impact

Taking part in Earth Hour is a great first step. It’s a chance to reflect, reset, and think about the role we all play in reducing energy use.

But the real impact comes from what you do next.
