This blog may help people explore some of the 'hidden' issues involved in certain media treatments of environmental and scientific issues. Using personal digital images, it's also intended to emphasise seasonal (and other) changes in natural history of the Swansea (South Wales) area. The material should help participants in field-based modules and people generally interested in the natural world. The views are wholly those of the author.

Hardly Massive!
England's land-based solar and wind turbine installations only currently produce about 17 gigawatt hours (GWh) of electricity. A University of Exeter study was carried out for Friends of the Earth. It estimated that the country's solar and wind power generation could be boosted to 130 and 96 GWh, respectively. Only 3% of land would be needed to achieve this (https://www.theguardian.com/environment/2024/apr/09/england-could-produce-13-times-more-renewable-energy-using-less-than-3-of-land-analysis ). Effectively multiplying the UK's renewable energy production by a factor of 13, could power all England's households, 2.5 times over. So, not even the entire 3% of land would be needed. The potentials for renewable energy productions in Scotland and Wales are, of course, much higher. It seems like a 'no-brainer' to a) massively boost land-based solar and wind turbine installations, b) to improve the electricity distribution to handle this and c) put in place new systems for storing energy (perhaps as heat?) to ensure supplies when the sun doesn't shine and the wind doesn't blow. This would be much cheaper, faster and less dangerous than building new nuclear power stations. It would even be better than siting wind turbines out at sea. It would be a quick way of the UK achieving its obligations, in terms of reducing 'greenhouse gas' emissions.
