Confusing government policy biggest threat to UK clean energy, says top academic

Lack of clarity is damaging investment in renewable energy, as well as gas and nuclear, says director of Imperial College London's centre for energy policy

The biggest threat to renewable energy in the UK, and the country's energy systems, comes from a lack of clarity on the part of government, a leading academic has said.

Rob Gross, director of the centre for energy policy at Imperial College London, said on Monday: "[There is a] lack of clarity over what they want people to do. This lack of clarity is erasing investment in everything. With more clarity, you would get more investment."
