Ed Miliband’s officials have admitted net zero will push up energy bills, while Donald Trump's energy secretary has branded the policy a "sinister tool to shrink human freedom".
Officials working with the energy secretary have acknowledged that the UK's net zero push will temporarily cause energy prices to rise.
The admission, The Telegraph reports, is an apparent contradiction of Miliband’s own claims.
A page on the government's website notes that the rolling out of green energy projects including wind and solar farms will inflate prices in the “short to medium term”.
Meanwhile, Chris Wright, the US energy secretary criticised the UK's drive towards hitting net zero by 2050, labelling it "sinister" and a bid to "shrink human freedom".
In a speech this week he said: "This is impoverishing your own citizens in a delusion that this is somehow going to make the world a better place. It’s not.
“Net zero 2050 is a sinister goal. It’s a terrible goal. It’s unachievable by any practical means.
“This is not energy transition. This is lunacy.”
