All countries are about 30-40% power generation and 20-30% transportation, look at most developed countries. The difference is our type of usage and fuels. The UK only has 1/3rd of Australias per capita, because they are thrifty with their usage, have switched to renewables, drive miserly vehicles short distances and rely on renewable powered public transport. Unfortunately Australia and the US are way behind these ideals. The UK has dropped rapidly from 12ish metric tons CO2 to 5 metric tons per person in pretty much the last 20 years due to pretty much wiping out coal use and turning the whole island into a wind farm. They also have strict vehicle emmission targets and large uptake of EVs. Meanwhile Autralia and the US sit around 15+ tons per capita. For goodness sake our top selling vehicles last year were the Ford Ranger and Toyota Hilux. The top 10 UK cars sold were mostly compacts and 2 in the top 5 were Teslas, only one mid sized SUV made the list (if you can even call it an SUV, it looks like a tall compact).
