Graham presented breakthroughs in renewable energy, including improved solar cell efficiency, advanced battery technologies, offshore wind developments, and community microgrids. The discussion covered how local communities can increase energy resilience through solar power, battery storage, and small-scale generation systems. Participants shared additional positive developments including biodiversity net gain initiatives, food waste management, balcony solar panels, and rewilding projects. The group explored how to measure success in local food resilience and discussed approaches to engaging farmers in regenerative agriculture practices, with several members sharing examples of successful community initiatives and partnerships with farming clusters. ### Next steps #### Belinda * Watch the recording of the meeting on catch-up. #### Cllr.Stuart * Provide more information on Solar Foods and their protein product Solein. * Investigate developing a small solar farm using sodium ion batteries. #### Graham * Share the recording of the meeting this afternoon. #### Sue * Look up Cllr.Stuart on the Town Council website for public facing environmental projects. * Sound out the local wildlife trust about the idea of creating 100 new log piles for residents. * Consider focusing on local food production and agriculture for her mayoral year, and explore how to engage with local farmers. * Look up Jenny's contact (Sussex peasant/Edin) for local food and regenerative farming connections. ### Summary #### Environmental Technology Breakthroughs Discussion Graham opened the meeting by discussing the need to share positive environmental news to counter gloomy reports, focusing on recent breakthroughs in energy transition technologies. He highlighted improvements in solar cell efficiency, advancements in battery storage systems, and the UK's leadership in offshore wind turbine technology, particularly floating wind turbines. The discussion included a question from Sue, the newly elected mayor of Battle, about environmental initiatives for her town, to which Graham suggested looking at community-level projects and mentioned that ideas from the day's presentation could be relevant. #### Renewable Energy Progress and Challenges Graham presented significant progress in renewable energy, noting that renewables now provide over 50% of UK electricity generation compared to just 2% two decades ago, with wind power being the main contributor and solar increasing steadily. He discussed various technological developments including MIT's electrically charged concrete, precision agriculture using AI drones, digital twins for flood forecasting, and advancements in electric vehicles with improved range and charging speeds. Graham concluded that while the technology for addressing climate change is available, the main challenge now is persuading decision-makers to implement these solutions, emphasizing the importance of local energy generation and storage systems. #### CO2 Emissions Reduction Strategies Stuart highlighted the need for accelerated action on reducing CO2 emissions and suggested investing in renewables rather than CO2 removal technologies. He also discussed solar foods, specifically mentioning a protein called solein made from bacteria that converts CO2 and hydrogen into protein, which is licensed for consumption in Singapore and partially approved in the US. Gary presented positive environmental developments including biodiversity net gain, food waste management, and new solar panel options for homes, while also mentioning upcoming housing regulations requiring solar installation and rewilding initiatives. #### Environmental Resilience and Food Systems Sue expressed gratitude for learning new concepts and discussed the balance between individual responsibility and government action in addressing environmental issues, particularly regarding lifestyle changes and technology improvements. Graham shared insights about market gardening and the benefits of worm composting from a garlic farm case study on the Isle of Wight, highlighting a 30% productivity increase and plans to develop a market garden. The group discussed how to measure success in local food resilience, with Graham suggesting tracking local supermarket supply sources and Cllr.Stuart mentioning research on children's health benefits from playing in soil. #### Community Energy Benefits Discussion Belinda discussed the challenge of demonstrating the benefits of community energy projects, noting that while carbon emission reductions are measurable, social benefits like health and wellbeing are more difficult to quantify. She mentioned the Ashton co-benefits toolkit as a resource for measuring these benefits. Cllr. Stuart shared information about sodium ion batteries becoming available domestically, stating they are safer and potentially cheaper than lithium ion batteries, though still more expensive. The discussion also touched on the current renewable energy generation levels and the challenges with V2G technology standards. #### Carbon Capture and Agriculture Discussion Graham and Cllr.Stuart discussed carbon capture technology, with Cllr.Stuart noting that Climeworks aims to capture one million tons per year but currently operates in thousands. They identified bureaucratic and political opposition as key barriers to implementing renewable energy solutions, particularly for community energy projects. Sue raised concerns about poor soil quality and how to implement regenerative agriculture practices, with Cllr.Stuart suggesting working through farm clusters as a potential solution to reach farmers and promote regenerative techniques. #### Regenerative Agriculture Initiatives Discussion The group discussed regenerative agriculture initiatives and local farming practices. Jenny suggested contacting Edin from Sussex who works with regenerative farmers and has set up information boards about agricultural practices at his market stalls. Belinda shared details about Dorset Council's work with county farms, including funding for farm surveys and farmer engagement through breakfast events with FWAG. The discussion concluded with Sue proposing to create 100 new log piles for residents to support bug habitats, though Garry raised concerns about potential theft for wood burners. *** #### Useful Links: Banter 120: ### Solar Foods - creating food without agriculture/food out of thin air: *** #### Chat: Banter 120 00:13:05 Stephanie Juniper: Wildflowers, meadows throughout the Abbey :-). ### 00:13:25 Stephanie Juniper: We are using Foamstream as a weed killer which doesn’t use pesticides.
