Tasmania’s state-owned Hydro-electric power generator could face legal action for damages after admitting it cloud-seeded in or near water catchments the day ­before disastrous flooding, although heavy rain was forecast.

Tasmania  shut their only fossil fuel power plant in August last year, and relied on renewable energy and one sole Basslink electricity cable to mainland Australia. The cable was supposed to be a back up supply but was bringing in 40% of Tasmania’s electricity, and it broke in December. But a green and greedy approach in Tasmania meant that the state had already run its dams down to 26% levels by selling too much electricity to the mainland at high “renewable” subsidized prices. That was a low level at the start of summer, normally a drier season in Tasmania. After the Basslink cable broke, the dam levels fell to a precipitous 13%, so fast that the green state had to bring in diesel generators just to keep the lights on. They also switched back on the Tamar Gas plant in late January. So much for being the “100% [...]
