Power generators make more money when burning coal

An energy commentator says power generators - or gen-tailers - make more money when they're burning coal. That's created a perverse incentive which is blocking new renewable power projects. Last year, Aotearoa imported 1 million tonnes of low-grade, dirty-burning coal from Indonesia because there wasn't enough wind, rain or gas available.
