Senator LAMBIE (Tasmania—Deputy Leader and Deputy Whip of the Palmer United Party in the Senate) (14:41): Mr President, I ask a father supplementary question. Given that the minister agreed that (1) the national RET scheme was designed to limit the environmental harm coal fired power stations caused and (2) Tasmania uses hydro renewable energy and has no dirty coal fired power stations, can the minister explain why he supported a national RET system that effectively forces every Tasmanian business and household to pay an extra tax of tens of millions of dollars a year in order to replace mainland coal fired generators with renewable power generation?
