Britain has reached several major milestones in its development of renewables during the past year. It established a national Green Investment Bank and confirmed a reduction from one tradable Renewable Obligation Certificate (ROC) to 0.9 ROC/MWh for onshore wind – ending speculation over much deeper cuts, which had eroded industry confidence. This 10 percent cut was originally proposed by the Department of Energy and Climate Change (DECC), but rumors that further cuts – up to 25 percent – were under consideration had driven leading wind turbine manufacturers to write to the energy minister, warning that continuing uncertainty was a risk to investment in the UK.
