São Paulo: Brazil's Bank of the Northeast, BNB, is looking for new sources of capital for wind power, as itfaces increasingly high demand for development funds, Recharge has learned. BNB is also calling for greater investor participation, due to greater risks from tighter margins and uncertainty over output levels.

José Danilo Araújo do Nascimento, of the bank's public-sector business division, says he is "seeing difficulty in 2011" in funding wind farms.
