| In their report, the engineers say that wind energy can contribute about 20% of the UK's electricity demand without the need for a significant upgrade to the network. Beyond that level though, it gets more difficult. | In their report, the engineers say that wind energy can contribute about 20% of the UK's electricity demand without the need for a significant upgrade to the network.

| The Department of Energy and Climate Change (Decc) said that wind was a critical part of the energy mix, the government supported the development of onshore wind in suitable areas and that planning reforms had given communities greater say over the siting of wind farms in their areas. | The Department of Energy and Climate Change (Decc) said that wind was a critical part of the energy mix, the government supported the development of onshore wind in suitable areas and that planning reforms had given communities greater say over the siting of wind farms in their areas. |
| Concerns over the costs of wind energy have also been highlighted by the Renewable Energy Foundation who say that subsidy payments for energy that is generated when there is little demand for power, are at a record high. | Concerns over the costs of wind energy have also been highlighted by the Renewable Energy Foundation who say that subsidy payments for energy that is generated when there is little demand for power, are at a record high. |
