Join EnerGeno in Heilbronn

Join EnerGeno in Heilbronn EnerGeno Heilbronn-Franken eG is a staffed citizen cooperative for solar, wind, and efficiency in the Heilbronn-Franken region. You can join from 100 euro per share, up to 350 shares (35,000 euro) at entry. What you can do - Apply online on Mitglied werden - Call 07131 2641-610 or write kontakt@eghf.de if you prefer the public office - After year one, dividends follow the general meeting. The first year after drawing pays no dividend so capital can go into plants How it works Fill the digital form, wait for the confirmation mail with a transfer template, then pay. One member, one vote, even if you hold more shares. Cancellation is toward year end with a two-year notice. Why it matters A professional team plus member capital is how Heilbronn-Franken keeps building arrays instead of waiting for a distant utility calendar.

Park a Klimakiste for bees and neighbours

Roll native planters onto a paved square The Helix Klimakiste is a pre-grown wooden box (about 120 × 100 × 80 cm) with a solitary shrub and flowering underplanting. Citizen initiatives, schools, and cities can move boxes in for events or trials, then move them again. Plant for wild bees from day one. What you can do - Propose Klimakisten for a schoolyard, market, or temporary greening ask via Helix Klimakiste - Help water and tend boxes when your group hosts them - Choose native perennials so insects find food on sealed ground How it works Boxes arrive cultivated and move with a pallet jack. They buy time: prove that plants change how a place feels before you unseal asphalt for good. Why it matters Paved plazas can still feed bees and invite conversation. Temporary green is a rehearsal for lasting canopy.

Trial traffic calming with mobile green

Test a greener curb before permanent rebuild Mobiles Grün lets neighbourhoods try converting a parking or traffic strip into stay-space with planters and seating. After a successful trial, cities can lock in lasting greening. Fast, reversible, and cheaper than guessing. What you can do - Ask your Ortsbeirat or district office for a timed parking-bay greening pilot - Partner with schools or Bürgerinitiativen to staff watering and weekend presence - Document who uses the space, then push for permanent unsealing if it works How it works Mobile containers and parklet-style kits occupy curb space for a set period. Neighbours live with the change, then decide together whether to keep it. Why it matters Streets learn in public. A temporary green bay is how communities prove cooler, quieter blocks without waiting for a full rebuild.

Green shade routes & unsealing for urban cooling

More green, less grey, cooler streets by design Heat and sealed surfaces go together: asphalt stores warmth, while trees and unsealed soil cool the block. Cities are extending Schattenwege (shade routes), depaving yards, and co-designing green corners with residents. What you can do - Walk a municipal Schattenweg route and suggest the next link (Esslingen extends its shade path each summer) - Join participation formats for new neighbourhood green (for example FairFuture co-design in Hamburg-Veddel) - Support local Flächenentsiegelung projects that swap paving for planting (Recklinghausen Hitzeschutzbündnis model) Why it matters Every square metre unsealed is a small air conditioner the whole neighborhood shares, biodiversity and comfort in one intervention.

Sit in a Mobiles Grünes Zimmer

Rest in a rolling green room on the plaza Helix's Mobiles Grünes Zimmer is a freestanding green wall and kiwi trellis on a roll-off container: shade, edible herbs, seating, and a climate-adaptation demo that cities, schools, and citizen groups can host. Since 2016 the rooms tour public squares, stations, and events across Germany. What you can do - Sit and cool off when a room is deployed near you (Stuttgart-Feuerbach station plaza has hosted one) - Ask your school, Ortsbeirat, or Bürgerinitiative to host a room for a festival, heat day, or neighbourhood pop-up - Use the side panels as a meeting point for climate and greening talks How it works A truck drops the pre-grown room; Helix handles most care. Local organisers top up the water tank. Residents get an instant cool oasis without digging the square. Why it matters Heat islands become places to linger. Neighbours feel what green infrastructure can do before permanent plantings arrive.

Walk the lower Neckar floodplain with AUN

Walk the lower Neckar floodplain with AUN The alliance names six nature reserves along the lower Neckar, including Altneckar Heidelberg-Wieblingen. Site walks (Begehungen) are how neighbours learn dam care, flow, and floodplain mosaic on the ground. What you can do - Watch the AUN page for the next announced walk - Meet the group at the listed reserve rather than inventing your own path - Bring binoculars if you have them: kingfisher and great-crested grebe are regular floodplain neighbours How it works Walks are announced with the monthly programme. This is not a standing weekly shift. When & where Seasonal / by announcement. Approximate pin on the Heidelberg Neckar meadows (Neuenheim riverside): 49.4146, 8.6925. Confirm the reserve and meeting point with AUN. Why it matters Seeing the floodplain on foot turns a policy alliance into a place you can care for.
