Joint Declaration of the Plug-In Solar Conference 2025

Empowering Citizens for a Renewable Future

We, the undersigned stakeholders from business, academia, policy, and civil society representing diverse regions and backgrounds, convened at the Plug-In Solar Conference 2025 to address one of the most urgent challenges of our time: the full transition to renewable energy.

Recognizing the urgency of achieving 100% renewable energy systems globally, we jointly declare:

1. Citizen participation is essential

The full transition towards renewable energy is only possible if citizens are empowered and enabled to actively participate in the generation, storage, and management of energy.

2. Accessibility and affordability are key

To maximize the number of citizens involved, participation must be affordable and accessible, including through do-it-yourself (DIY) solutions that lower the threshold for engagement.

3. Plug-in technologies drive participation

Plug-In Solar Kits and Plug-In Batteries have proven to be effective and scalable tools for democratizing energy production and consumption, allowing even renters and apartment owners to contribute directly to the renewable transition.

4. Towards a decentralized energy grid

The widespread use of small-scale plug-in devices is fostering the emergence of decentralized energy grids that are more resilient, efficient, and cost-effective than traditional centralized systems.

5. Integrating small-scale solutions in grid management

National and regional energy strategies must recognize and integrate small-scale production and storage in grid management. Doing so introduces critical flexibility, stabilizes supply, and accelerates the transition towards affordable and secure 100% renewable energy systems.

6. Call to lawmakers

We urge lawmakers around the globe to swiftly remove regulatory barriers and establish strong incentives to promote the broad adoption of plug-in solar and storage technologies.

7. Energy democracy: the future is in the hands of citizens

We affirm that the future of energy lies in decentralized citizen participation. By empowering individuals, families, and communities, we can ensure a faster, fairer, and more resilient energy transition.

In solidarity and commitment, we sign this Joint Declaration to work together towards an energy future led by the people, for the people.
