"Wind power in Britain is predictable enough that the grid can rely on it to help keep the lights on, despite spells of cold, calm weather, while it cuts carbon emissions significantly, the Institute for Public Policy Research (IPPR) said.
"... The National Grid has said it can accommodate 30 gigawatts (GW) of wind power by 2020, slightly more than the 28 GW the Government expects to be online by that time to help meet its carbon reduction targets. About five GW are online currently."
