There is much to do to create a modern energy paradigm, one that is clean, sustainable, and economically viable, but the changes are coming as overall efficiencies improve and manufacturing costs decrease for today’s renewable technologies. In 2000, 0.6% of total global energy production was generated either by wind or solar, a 50% increase in a decade; by 2010, the amount had doubled.1 By 2013, Spain had achieved a global first as wind-generated power became its main source of energy (21% of total demand, enough to run 7 million homes2), while both Portugal and Denmark now regularly produce days powered 100% by wind.
Historically cloudy England scored a first, as solar became the largest source of grid energy during an especially sunny 2018 spring bank-holiday weekend,3 while in the midst of high winds from Storm Bella on Boxing Day in 2020, the UK was more than half powered by wind, a new record.
