18. What steps he is taking to encourage businesses to install solar energy panels. 
The solar PV strategy, which we published last spring, sets out how we are maximising the deployment of panels on commercial and industrial buildings. We have taken a range of actions to assist owners of such buildings to deploy solar PV panels. To name just a few, we have consulted on allowing the transfer of panels without the loss of feed-in tariff accreditation; we have made changes to the feed-in tariff to protect the incentive for building mounted solar; and we are working with the property sector to remove other barriers to deployment.
Vaillant in my constituency is a shining example in this area. It is energy efficient because it has so many solar panels. Does my right hon. Friend acknowledge that after 13 years of Labour, just 6.8% of British electricity came from renewables, whereas since 2010, renewables generation has more than doubled?
The hon. Lady is absolutely right. Renewable electricity generation has more than doubled. In fact, it has gone up by 165% in just a short time. Solar has played a key role in that.
