A recent study has revealed that two-thirds of proposed green energy projects in Great Britain have failed to progress past the planning stage in the last five years. This setback is hindering the country's transition towards clean electricity generation. The analysis of Britain's "renewables pipeline" showed that 63% of planned projects were either abandoned, denied planning permission, had their applications withdrawn, or expired between 2018 and 2023. Only a minority of applications were approved or revised during this period, according to research conducted by Cornwall Insight. This trend of speculative applications for renewable energy schemes not progressing is slowing down the shift towards cleaner electricity in the country.
