Australia is about to set its 2035 emissions-reduction target, likely somewhere between 65% and 75% (Climate Change Authority). For context, a 70% cut means shrinking national emissions from about 440 million tonnes of CO₂-equivalent to roughly 132 million tonnes (DCCEEW quarterly update). The headline numbers are big. The debate over cost versus benefit is bigger.
Australia loves solar. One in three homes now sports panels. But here’s the kicker: fewer than one per cent of those panels were made here. Round 2 of the federal Solar Sunshot program is the first serious push to change that, with $150 million aimed squarely at turning Aussie ideas and capability into kit we actually build at home.
If you’ve bought an electric car to rein in the household budget, good news: pushing electrons is almost always cheaper than burning dinosaurs. The twist—and it catches plenty of new owners—is how wildly the price of a “fill” swings depending on where and when you plug in.
If you’ve ever stood under a hot shower thinking, “I wonder if this is costing me more than my last weekend away,” there’s a good chance your water heating system is guilty as charged. Traditional electric hot water heaters are basically kettles on steroids, chewing through power to keep water hot even while you’re off at work or the beach. Imagine the amount of energy being consumed by these systems globally when it’s totally unnecessary to keep the water hot just in case someone might turn the tap on.
