From July to December 2020 Regen worked with Scottish and Southern Electricity Networks (SSEN) to produce energy efficiency demand reduction factors for both the North of Scotland and Central Southern England licence areas. This analysis used scenarios to look at the impact of domestic, commercial and industrial energy efficiency measures on electricity demand, down to primary substation level.
Jonty Haynes
Moving electricity from where it is generated to where it is used is fundamental to our energy system. After decades of incremental change, the UK's electricity infrastructure and systems now need to develop rapidly to support further decentralised generation as well as the increased electrification of transport and heat.
Inspired by the recent budget announcements and the current economic and public health crisis, I'd like to look at the costs to the public of inefficient housing, which the government continues to show wavering commitment to rectifying (Green Homes Grant, I'm looking at you), through the lens of healthcare. While there are many relevant and undervalued benefits to society from improving low energy efficiency homes, including but not limited to financial and carbon emissions savings, I believe there is a case for change on healthcare grounds alone.
