A new report by Bloomberg New Energy Finance (BNEF) and Vestas says an increasing group of green businesses are choosing to source all of their energy from renewables. Previous BNEF figures report that global investment in new renewable capacity surpassed that of fossil fuel generation in 2011, with $257bn invested in renewables compared with $223bn fossil fuels. Hydroelectric power, at 47 per cent of the total share, was the most popular form of company onsite renewable energy.
