Out with the old, in with the renewable
Like old cars, equipment in coal-fired power plants needs replacing often, and repairs can take days.
Last year, black coal plants in the National Energy Market broke down 74 times (once every five days).3 When they trip, they can’t be switched back on quickly, making blackouts more likely to occur.
Luckily, the solution already exists. The only thing lacking is political will. We must replace coal-fired power stations with renewable energy by 2030.
Solar and wind power is cheap and reliable. Battery storage like the Tesla big battery in South Australia can save the day during peak electricity use, supplying stored energy quickly into the grid.
