Zero Energy: Company Profile
Rooftop solar is one of the most effective ways to cut household carbon emissions.
A 6.6 kW system (roughly 18–20 panels) can generate around 8,000–9,000 kWh annually in Melbourne, supplying most of a home’s electricity and significantly reducing reliance on fossil-fuel-powered grid energy. This clean energy output can offset nearly 100% of a typical home’s usage, with excess fed back into the grid. Solar is a key part of Victoria’s net-zero goals, typically eliminating 5–8 tonnes of CO₂ per year.
It’s an essential step in transitioning to renewable energy and achieving meaningful environmental impact at the household level.
Installing a home battery (e.g. 10 kWh) maximises the benefits of rooftop solar by storing excess energy for use at night.
While it doesn’t generate power, it boosts solar self-consumption—raising it from ~20–40% to 60–80% of total generation. This reduces reliance on fossil-fuelled grid electricity during peak times. A 10 kWh battery charged daily can store around 3.65 MWh annually, offsetting energy that would otherwise come from gas or coal plants.
By shifting usage to clean, stored energy, batteries enhance energy independence and contribute to significant carbon emissions reductions, particularly in states like Victoria with fossil-heavy grids.
Switching from gas-fired HVAC to an all-electric ducted heat pump system significantly cuts fossil fuel use. Modern reverse-cycle systems offer both heating and cooling efficiently.
In Victoria, the average household uses around 50 GJ of gas annually for heating, generating about 2.5 tonnes of CO₂. Replacing this with a 16 kW heat pump powered by renewable electricity can eliminate those emissions. Government rebates support this transition, helping homeowners save up to $500 per year on heating costs.
Electrifying home heating is essential for achieving zero-carbon homes and reducing environmental impact while improving energy efficiency and year-round comfort.
Water heating is a major household energy use, often powered by gas or outdated electric systems. Replacing these with electric heat pump hot water units can reduce energy consumption by 60–75%.
For example, a heat pump may use only ~1,000 kWh annually versus ~3,000–4,000 kWh for old electric tanks, saving ~2,000–3,000 kWh and 1.7–2.6 tonnes of CO₂ per year. Replacing a gas unit also cuts ~0.8–1.0 tonnes of emissions. When powered by renewables, heat pumps can reduce emissions to near zero.
Experts call this one of the most cost-effective upgrades in a home’s transition to all-electric living.
Transportation is a major contributor to carbon emissions. Switching from a petrol or diesel car to an electric vehicle (EV), especially when charged with rooftop solar, can drastically reduce emissions.
Petrol cars emit ~180–200 g CO₂ per km, while EVs charged from solar have near-zero operational emissions. Even on Victoria’s grid, EVs emit ~100–150 g/km—still significantly lower. With solar, every kilometre driven saves ~0.18 kg CO₂, achieving a 97% emissions reduction.
Pairing an EV with solar energy not only slashes running costs but also makes personal transport cleaner, helping households dramatically reduce their environmental impact while gaining long-term savings.
