illuminem summarises for you the essential news of the day, reviewed by our editorial team. Read the full piece on Grist or enjoy below:

🗞️ Driving the news: California has approved plug-in “balcony solar,” allowing residents to install small solar systems that connect directly to household electrical outlets without the traditional utility interconnection process
• The measure could make solar more accessible to renters and apartment residents who cannot install rooftop systems

🔭 The context: Plug-in solar has already expanded in countries such as Germany and is emerging in several U.S. states
• These smaller systems produce less electricity than rooftop installations, but they can reduce household grid demand, particularly during sunny periods when air-conditioning loads are high

🌍 Why it matters for the planet: Distributed solar can increase renewable electricity generation while reducing reliance on fossil-fuel power, especially as electricity demand rises from electrification and data centers
• Generating power close to where it is consumed can also reduce pressure on the grid during peak periods.

⏭️ What’s next: California’s rollout could influence other states considering similar rules
• The economics will depend on system costs, electricity prices, household circumstances and whether governments provide rebates or other incentives

💬 One quote: “The big reason this is a big deal really is because it’s the most affordable way for people to actually participate with solar PV,” - Amanda Smith of Project Drawdown

📈 One stat: Plug-in solar systems can cost a few hundred dollars, with the article citing an estimated payback period of around four years through electricity savings
