Earth Day is observed on April 22 each year as a reminder of our shared responsibility to protect the planet we call home. First celebrated in 1970, it started as a response to the growing environmental impact of oil spills and pollution in the US and has since sparked a global conversation about our footprint on the planet.  

The theme for Earth Day 2025, "Our Power, Our Planet", asks each of us to take action for a cleaner, more sustainable future, with a special focus on embracing renewable energy. 

Australia, a country once heavily reliant on fossil fuels like coal and natural gas, has undergone a remarkable energy transformation in recent years. For decades, these fossil resources powered the nation's economy but also contributed to environmental degradation. 

So, how are we faring with renewable energy?

This year, Australia's renewable energy sector is projected to account for up to 50 per cent of the country’s electricity generation. Solar energy is expected to account for about 20 per cent of Australia's electricity generation, with wind energy anticipated to contribute a further 15-20 per cent to the country's energy mix. 

These advancements are an impressive leap from 2010 when Australia’s renewable energy sector remained in its infancy. Thanks to decreasing solar panel costs, supportive government policies, and the growing demand for clean energy, Australia has dramatically increased its renewable energy uptake. However, further regulatory reforms are necessary to meet the current target of net-zero emissions by 2050. 

States like Canberra (100 per cent renewables), Tasmania (98 per cent renewables), South Australia (74 per cent renewables) and Victoria (40 per cent renewables) are leading the way with bold renewable energy targets, driving change at the local level. Other states are also making progress with their renewable targets, but there is still room for improvement in their uptake of clean energy to catch up to these leading states.  

It’s important to remember that we can all contribute to a sustainable future by taking practical steps in our daily lives. Here are some ways you can join the movement and make a lasting impact: 

Switch to renewable energy 

Installing a solar panel on your home can reduce your carbon footprint and contribute to the fight against climate change. For instance, a solar heat generation system can reduce carbon emissions by up to 2.5 - 3 tonnes per year by replacing conventional gas or electric heating with solar-powered alternatives. If installing solar is not an option for you, however, choosing a green energy provider or getting involved in community solar projects are other choices you can make to support renewable energy.

Engage in tree planting events 

Not only do trees help produce oxygen and sequester carbon dioxide from the atmosphere, they also play a vital role in cooling our surroundings. Planting more trees in your area can reduce the need for air conditioning during warmer months, leading to lower energy consumption. Whether it’s a few native species in your garden or a larger community effort, tree planting makes a real difference. Visit National Tree Day to learn how to get involved in Australia’s largest community tree planting event. 

Be mindful in your everyday energy use 

What may seem like small actions, can have a big impact over time. From turning off lights when they’re not in use to unplugging appliances and reducing "vampire power," small changes in our day-to-day household choices can help lower energy consumption. 

Consider more sustainable transport options 

Transportation is a significant source of carbon emissions, so switching to electric vehicles (EVs) or using public transport when possible helps make a difference. Active transport such as walking or cycling for short trips can also reduce your carbon footprint and benefit your health. 

Take action within your community 

Join a local clean-up, community garden or tree planting event. If there isn’t one near you, it’s a great opportunity to start your own! There’s strength in numbers and it’s a great way to inspire others to act.  

Vote for climate-conscious leaders 

Support politicians and policies that prioritise the environment and encourage your local council to invest in sustainable practices. These actions can help create a greener community and drive positive change that extends beyond your neighbourhood.
