Former Republican congressman Bob Inglis knows something about the cost of climate change. It included his job.
Victoria and NSW have been warned they could follow South Australia in being hit by electricity blackouts in years ahead unless Canberra comes up with a bipartisan national plan to deal with energy and climate change.
"Clean coal" plants that the Turnbull government has flagged could get clean energy subsidies are more expensive than solar, wind and gas-fired power and would lead to higher electricity price rises, analysts have warned.
The Andrews government will pledge to cut Victoria's greenhouse gas emissions by up to a fifth by 2020, putting it at odds with Canberra on tackling climate change.
The government has confirmed Australia's greenhouse gas emissions are rising, and projected that it will not get near its 2030 climate target under current policies.
State and federal energy ministers have agreed to steps promised to stop companies price gouging on electricity bills, but been blocked from going further by the NSW and Queensland governments.
Prime Minister Malcolm Turnbull's disastrous week-long spat over a climate-change policy review has culminated in a showdown with state premiers in Canberra, and criticism from the nation's chief business group.
The Turnbull government is sitting on advice that an emissions intensity scheme would make electricity bills cheaper.
The irony of the hysterical attack by some MPs is that by ensuring the scheme isn't on the table they are likely to further aggravate the problems they describe in doomsday language.
The man who came up with the scheme at the centre of a humiliating government backdown on climate change policy says has rejection means the government will have be responsible for higher electricity prices and reduced energy reliability.
