Great Britain risks wasting a major achievement if it builds massive wind farms and nuclear sites without ensuring there are enough cables to bring the new electricity to homes and businesses, an official report has warned.It could leave wind turbines and solar panels standing idle, and lead to higher costs for customers across the country.The report - commissioned by the Government and written by a former National Grid boss - said it is "both vital and challenging" to ensure the delivery of new grid connections speeds up.It takes around 12 to 14 years to get new big transmission lines up and running, around twice the time it takes to put up a large wind farm, the report by Nick Winser said.This is slowing the transition to clean energy as developers of wind and solar farms are having to wait to have their sites connected to the grid.Britain needs enormous new investment to deliver the clean electricity that will power cars, homes and industries in the future.
