Local Clean-Tech Cooperatives (CTCs) have emerged as a significant driver of decentralized green investment across the UK. In 2023, a record number of local communities formed cooperatives to invest directly in small-scale wind and solar installations. This localized model helps communities secure green energy at stable prices while redirecting profits back into the local economy. A survey by the Clean Energy Coalition UK showed that 68% of community members invested primarily to reduce carbon emissions, while 32% were motivated by long-term energy security.
With rising policy focus on regional decarbonization, many CTCs have expanded into local battery storage schemes and community-owned EV charging hubs. The income elasticity of demand for community-supported green energy subscriptions is estimated at +1.8, indicating that participation in these schemes is highly responsive to rising household incomes.
| Year | Number of registered CTCs |
|---|---|
| 2017 | 140 |
| 2018 | 180 |
| 2019 | 240 |
| 2020 | 320 |
| 2021 | 450 |
| 2022 | 600 |
| 2023 | 810 |
Using Fig. 2, calculate the percentage increase in the number of registered Clean-Tech Cooperatives (CTCs) in the UK from 2018 to 2023.
