you also appear to have failed math in primary school and beyond
if "Yallourn power station supplies more than a fifth of the state's energy" and the state has 70% of it's energy from coal.......how much remaining energy is from coal if Yallourn is off line.....?
and for extra remedial marks......what's Victoria's renewable energy generation a percentage after Yallourn goes off line......?
(hint......you can assume that Yallourn supplies less than a quarter of the state's energy and express your answer as a range)
