Where the Sun Don't Shine?

There's an energy crisis. One of the fastest ways of limiting its immediate impact, would be to boost land-based solar farms. The UK's Environment minister seems more 'hung up' on 'growth' (https://www.theguardian.com/environment/2022/oct/10/ministers-hope-to-ban-solar-projects-from-most-english-farms). The Environment minister is planning to ban the development of solar farms on most of England's farmland. He argues that placing solar panels on agricultural land will threaten his programme intended to boost 'growth' and enhance food production. It's not a bad idea to encourage local production of as much food as possible. Much of UK farmland is currently used, however, for grazing cattle and sheep. This is not especially energy efficient. One could also argue that urban-based hydroponic developments could be more productive than replacing grazing with crops. If the UK government (going against its 'nanny state' antipathy) wants to block the creation of solar farms on English agricultural land, perhaps it needs to massively encourage placing solar panels on urban buildings and/or along motorways?
