The reality is that not all of our energy has the same carbon footprint associated with it – different parts of the country have different energy mixes. To capture that, the National Grid measures what it calls "carbon intensity", essentially a measure of how "clean" energy is at any given time. Energy from renewables is notoriously difficult to store – hence the push to develop more battery storage systems across the UK. Such a large difference can have a massive impact on the carbon footprint of energy-intensive industries based around the country. Moving it north of the Border would have reduced its carbon footprint by 73%.
