Charting a way to net zero can be difficult even with consistent policy-making and high levels of investment. According to the Commonwealth Scientific and Industrial Research Organisation (CSIRO), energy production, residential and commercial fuel use, and transportation are among the biggest contributors to Australia’s overall greenhouse gas emissions. A good way forward in these sectors seems to be increasing energy-efficiency on both the supply and demand sides—using clean energy to power heat pumps and electric vehicles, for example. In practice, however, the steps required to proceed in this direction are not always clear. Where will all the extra electricity required come from?
Making lighting more energy-efficient should definitely be part of the answer. According to our own research and simulations,* roughly 50% of all light points in Australia are energy-inefficient incandescent and fluorescent. Switching these to connected LED could significantly impact both the country’s economy’s carbon footprint and its finances. Our internal modelling suggests that shifting all conventional light points in Australia to connected LED could save up to AUS$8.1 billion each year, while reducing CO2 emissions by an estimated 7.9 million tons annually, equivalent to the emissions saved by cancelling all cross-continent passenger flights between Melbourne and Sydney for the next 10 years.
Crucially, connected LED lighting frees up electricity that can then be used to power other resources. According to our own simulations, for example, the estimated energy saved by shifting all conventional light points to connected LED in Australia could power as much as 3.8 million heat pumps, 4.4 million electric vehicles, or 5.2 million electric cooking units each year.
