Federal Treasurer Scott Morrison has labelled the Queensland government's persistence with a renewable energy target "a muppet of a proposal".

Mr Morrison is spruiking the federal government's new energy plan, announced this week, which it claims will save households up to $115 a year by 2030.

The plan ditches the Clean Energy Target proposed by Chief Scientist Alan Finkel in his report this year, which is supported by the Queensland government.

Mr Morrison said the Palaszczuk government's target of 50 per cent renewable energy by 2030 was unsustainable and would lead to higher electricity prices.
