How rooftops can supercharge solar energy
The Climate Change Committee(CCC) is an independent group of experts who advise the government on how to reduce our carbon emissions. It recommends that 54GW of solar capacity is needed by 2035. Indeed, the UK government has now set an even more ambitious target of 70 GW of solar energy by 2035. CPRE. Both for new buildings and for retrofits, we support a 'fabric first' approach. This approach focuses on minimising energy use before turning to. Then there are car parks. Covering land with tarmac and storing cars on it has no place in 21st century land-use policies. Sure, cars need to be parked, but if we put homes above them and a mix of solar and green roofs on top, the win. As part of our campaign, we are calling on the government to unleash a rooftop revolution by urgently taking these steps: 1. Managing the potential. We're running a campaignto urge the government to fully realise the potential of solar on rooftops and other 'grey' spaces. From warehouses to schools, car parks and farm buildings, we can quickly roll out renewable energy without.
