Renew Extra Weekly

 While renewables are being supported in the UK by private sector investment, most recently via the Contracts for Difference market system, with no direct government cash input, over 70% of the UK Department of Energy Security and Net Zero expenditure is now nuclear related. DESNZ’s annual report and accounts says that ‘Great British Energy – Nuclear has remained a key component of the Government’s approach to energy security and decarbonisation, with work continuing to support the delivery of new nuclear projects, providing greater certainty for industry and investors, supporting highly skilled jobs across the supply chain, and contributing to a resilient, low carbon energy mix’.  It notes that through the Spending Review the department secured a capital settlement of £62.8bn from 2025-26 to 2029-30 and a resource settlement of £5.8bn from 2026-27 to 2028-29, including £8.3bn for GBE/GBE-Nuclear including SMRs and £14.2bn for the new Sizewell C European Pressurised-water Reac...

 The soon to be UK Prime Minister, Andy Burnham, is being portrayed as a ‘new broom’ that could, or might, adopt better polices in all areas. Well, what about the energy sector?   It’s in a mess, economically, driven by high fossil gas prices, with retail electricity prices at an all-time high, despite renewable energy doing well (65 GW so far) with its wholesale price mostly being low. It’s in a mess technologically, at risk of undermining the crucial next stage of its important renewables programme by diverting cash to support major high-cost nuclear and fossil carbon capture and storage projects.  Both of these programme involve multi-billion funding. The much delayed Hinkley Point nuclear plant may end up costing £40-50bn, inflation adjusted, when it finally gets completed, probably in 2030. Its follow-on project, Sizewell C, may not do much better, despite promises about learning from Hinkley, and despite the investment risks being met by a consumer levy.  ...

 Renewables remain the cheapest source of new electricity in most markets and have further strengthened their cost advantage over fossil fuels. New cost data from IRENA, the International Renewable Energy Agency, shows that renewables helped avoid an estimated USD 480 billion in fossil-fuel costs in 2025, protecting users against fuel-price volatility.   So the story so far is a good one - a technological and economic success, for wind and solar especially. With costs falling dramatically, they have both boomed globally and look likely to continue to do so, with wind going offshore and into deeper water, thanks to floating systems, and floating solar PV arrays also spreading on lakes and reservoirs. Agri-solar/ solar grazing projects are also getting popular. Projections see solar beating all comers globally in the years ahead.  What about the other renewables? Although so far less developed, new wave and tidal projects also continue to emerge around the world, t...

 The heatwave across Europe over the last month, with temperatures reaching 40 C and more, had a big impact and seems consistent with what might expect from climate change . The record-breaking temperatures recorded over Europe would have been ‘virtually impossible’ 50 years ago, according to the World Weather Attribution service, with climate change being ‘unequivocally to blame’. It certainly is worrying , with  the excess death statistics across Europe rising- including over 1000 in initial reports from France and up to 900 reported in Spain , all this being coupled with huge economic disruption costs. It’s still continuing as I write.  And we are likely to see more regularly repeated extreme heatwave episodes like in the years ahead, with even higher peak temperatures – and with the impacts of rising heat in some parts of the word already being much more severe than in Europe. In India especially.   In addition, there are the other impacts of global clim...
