The coalition has unveiled measures it says will knock £50 off the average energy bill, but some of that cost will be absorbed by taxpayers.
The Government has laid out its ideas on how to cut energy bills this winter - but the plan has been put together in haste.
With prices going up, millions of the big 6's customers certainly feel the firms are making too much cash. How much are they really making?
The UK Independence Party has called the cut to onshore subsidies a "political stunt" to buy off voters opposed to turbines "despoiling the British countryside".
Energy spokesman Roger Helmer said the change "fails to address the real argument which is the nonsensical and frankly dangerous energy policy this Government is forcing upon UK taxpayers".
He said the taxpayer would still have to fund "this wasteful and downright ridiculous technology to be built out of sight".
An industry body representing the renewable energy sector has said that Government changes to subsidies are good news:

Today is actually a good news day for renewable electricity and renewable heat.
The real reason that support for solar and onshore wind will go down is that they are leading the race for cost-competitiveness with fossil fuels. Government policy is working and bringing down costs.
The important thing is that decisions are evidence-based, not purely political, and we need to see the methodology to assess that.
Prime Minister David Cameron has told ITV News' Deputy Political Editor Chris Ship that the coalition's announced cut in energy bills was not in response to Labour's proposed energy price freeze.
Speaking in China, Mr Cameron said: "We have been discussing within the coalition the issue of energy bills for years now. It has taken me longer than I would have liked but I'm very glad we put in place at least some relief on the issue of energy bills."
Energy Secretary Ed Davey has said that the decision to reduce subsidies was driven by the falling costs of generating onshore and solar energy, and not political pressure.
He told ITV News: "Because of our investments in renewable energy, we are seeing the costs fall ... It means we can still develop onshore wind, still develop solar, but it means we can also bring on some of the technologies for the next decade like offshore wind".
Rural wind farms have been a source of coalition tension, with many senior Conservatives staunchly opposed to the turbines, which Liberal Democrats say are needed to meet environmental objectives.
The UK currently has roughly four wind turbines on land for each one at sea, according to the trade association Renewable UK:
- Offshore wind power - 1,075 turbines (3,653 MW capacity)
- Onshore wind power - 4,175 turbines (6,772 MW capacity)
Danny Alexander has insisted that onshore wind energy will continue to play "a big role" in the UK, despite the decision to reduce Government subsidies in this area.
The Liberal Democrat Chief Secretary to the Treasury said state help for onshore wind and solar was being reduced "slightly" in favour of offshore wind.
But he told BBC Radio 4's Today programme that the move would present better "value for money" and could open the way for an extra 10 gigawatts of energy by 2020.
The "strike prices" for renewable energy - the amount of subsidy the taxpayer pays to entice investors to make long-term commitments - is already set well above the current market value, but will be slightly lower for onshore wind and solar.
The boss of energy firm npower has said he would be receiving a "much reduced" bonus because of his company's poor customer service.
Chief executive Paul Massara apologised for what regulator Ofgem dubbed the "serious deterioration" in customer service.
He told Daybreak: "The fact is we haven't delivered the customer service they deserve.
"When the board sit down and review my bonus they will reduce my bonus because I haven't actually delivered for customers."
Energy companies were guilty of "outrageous blackmail", according to a consumer campaigner, who saw the latest attempt to cut bills by £50 as an empty gesture.
"I'd be more impressed if energy companies had said they were going to lower bills by an average of £50 and were going to do it now," Ann Robinson of Uswitch told Daybreak.
She expressed scepticism over the "Big Six" energy companies motivation and what the Government could do to intervene on behalf of struggling consumers:
"I think there is a limit to what can be done. It is playing around the edges. It is not real. I also hear for example, is that one of things that the energy company is looking to is to delay even more the smart meter programme."
npower received five times as many complaints as the best performing energy firm SSE, research showed.
- npower had 202.5 complaints per 100,000, compared with 38.3 for SSE - the lowest level of the main energy providers - from the April to June period, Consumer Futures research showed.
npower also recently announced a 10% average bill increase but has said that it will reduce bills as a result of a shake-up of Government green levies.

Many npower customers will have noticed a serious deterioration in service levels over the last year.
The huge growth in complaints about npower is wholly unacceptable and is an issue that Ofgem takes very seriously and is why we intervened in this case.
npower's commitment that its customers will not lose out financially as a direct result of the company's billing system problems is important and we will expect npower to do all it can to identify and rectify such cases.
