David Cameron has won planning permission to put a wind turbine and solar panels on his west London home.
Mr Cameron has trumpeted his green credentials
Kensington and Chelsea Borough Council gave the go-ahead to the turbine, which will generate electricity for Mr Cameron's house.
Some neighbours have opposed the plan, saying the turbine will be an eyesore.
The planning committee approved the plan but imposed a size limit on the turbine and said it must be grey to make it unobtrusive.
They also told Mr Cameron, whose home lies in a conservation area, he must renew the planning permission after three years.
A council spokesman said that would give planners the chance to judge whether the turbine has disturbed neighbours or caused any other nuisance.
The councillors also said plans to build a basement at the property would need to be changed after concerns were raised about part of the development.
The news came as the government said it wanted to boost wind power and other renewable sources of energy as it published its energy review.
Barbara Want, wife of BBC Radio presenter Nick Clarke, was among neighbours who objected to the turbine plan.
She told the planning committee the plans would spoil the conservation area, which is largely made up of Edwardian two-storey homes.
"I love this area, I don't want to see it harmed and I believe that these proposals will harm it," she said.
Mrs Want said she particularly objected to the wind turbine and a "light well" which formed part of the planned basement.
Talking about the turbine, she added: "I think it would be an eyesore and would continue to be an eyesore because it would end up being a one-off.
"I don't think other people in that area would put them up. "People are not going to fork out £2,500 for 10% of their energy bills."
One of Mr Cameron's architects, Alex Michaelis, said the turbine and solar panels would contribute to more than 30% of Mr Cameron's energy bills.
The turbine might not be seen as completely unobtrusive, said Mr Michaelis, but better designs were constantly being developed which could replace it in the future.
The domestic turbine, thought to be one of only 600 in the UK, is the latest notch in Mr Cameron's green credentials.
He has hailed the virtues of recycling and ran his local election campaign on the slogan "vote blue, get green".
But critics accused him of hypocrisy when it emerged that while he cycles to work, a car follows carrying his papers.
Facing a wait?
The man who installed London's first domestic wind turbine on his house has warned it will not make Mr Cameron's home self-sufficient in energy.
Donnachadh McCarthy, who lives in Camberwell, told the Evening Standard newspaper: 'If his wind turbine is the same as mine, he will get between one and two kilowatts a day.
"But it does not all come in at the beginning of the day and if he needed 800 watts to use the washing machine, he would need to wait something like three hours for the turbine to generate that much energy, without using other electricity."
