Renewables still have a long way to go before becoming our primary source of electricity generation and intermittency still remains a major hurdle.
Nevertheless, our energy mix is improving. Consider this interesting fact:
At midday on the 21st of March 2018, the UK electricity demand was 44GW. Roughly 30% of this demand was met by a combination of wind and solar which generated 7GW and 6GW, respectively. Wind generation had a record year last year, representing 15% of the UK's energy mix in 2017, up from 10% in 2016.
