Australia has only recently started to embrace renewable energy. If they were to complete a total shift to renewable energy, it would pay for itself through cost savings within two decades, ultimately saving Australian $20 billion a year in combined fuel and power costs, a new report says. The authors behind the report cite that the dropping costs of renewable energy are creating momentum behind renewable that can only be slowed by policymakers, but not stopped. The report also says that it’s feasible that 40 percent of transport could be emissions free by 2035.
