Britain's new 3 billion pound "green investment bank" will at first focus on offshore wind, the department for business on said Tuesday.
The British government gave more details about the bank a day after bringing forward its launch date to April 2012, a year earlier than planned.
"Sectors likely to be eligible for intervention initially include offshore wind, non-domestic energy efficiency and waste. Work is ongoing to explore other sectors which will change over time," the department for business, innovation and skills said in a statement.
"Its initial remit will be to focus on green infrastructure assets and on the twin objectives of achieving significant green impact and making financial returns."
The government would at first make direct investments until the bank won EU state aid approval.
