By "cultural changes" you mean energy shortages. Realistically, this would most likely result in leaders getting elected out of office and resuming the use of fossil fuels. Regular blackouts are immensely unpopular.
Those of us who lived through the oil shock in the 70s are having a laugh at the 'just cut the energy supply' path. Would love to hear from people who endured the UK at the height of their 3-day week to see how keen people were about this forced change...
