How Solar Changed in 2025 (And What's Next). Go to https://surfshark.com/undecided or use code UNDECIDED at checkout to get 4 extra months of Surfshark VPN! I called 2024 the year of perovskite. But 2025? This was the year perovskites went from "interesting lab tech" to "you can actually buy these." Oxford PV shipped the first commercial batch to a US solar farm. California startups landed major infrastructure deals. And Chinese manufacturers started licensing the technology for mass production. More importantly, researchers solved problems that have plagued perovskites for years. We got self-healing materials that repair damage from heat and moisture. Cooling systems that boost efficiency by over 12%. And manufacturing techniques that broke the 34% efficiency barrier, which shatters silicon's theoretical 30% limit. So let's recap what actually happened this past year, what it means for solar's future, and what breakthroughs to watch for in 2026.

Why Coastal Cities Are Betting on Osmotic Power. Take your personal data back with Incogni! Use code UNDECIDED at the link below and get 60% off an annual plan: http://incogni.com/undecided What if you could power cities just by mixing river water with seawater? Around 15,000 TWh of energy pours into the oceans each year as freshwater blends with saltwater at river mouths. That amounts to roughly half the energy the world consumes in electricity every year. And we may have finally found a way to tap it. It’s called osmotic power, and it could provide clean energy around the clock. As freshwater becomes scarcer, more cities are turning to desalination plants to meet their water needs. Desalination is energy-intensive, but osmotic power could use the same salty wastewater from desalination to generate electricity instead of just dumping it back in the ocean. But how does this tech work? Could a combination of fresh and saltwater be the “solution” to the world’s ever-increasing energy demands?

Save 40% on the Ground News unlimited access Vantage plan with my link. What if solar panels could generate twice the power for a fraction of the cost, making them cheap enough that you'd actually want them on your roof? This is a solar cell made with both perovskites and graphene, the record-breaking result of a collaboration between three Aussie teams. This perovskite cell initially had an efficiency of 16.65%, behind the 20% efficiency range of standard silicon. The introduction of graphene, though, almost doubled that initial figure to 30.6% … all while cutting production costs by 80%. How is this possible? And more importantly, when might these actually end up on your roof?

AI’s Secret Impact on Your Power Bill. Head over to https://eightsleep.com/mattferrell and use the code MATT to get $700 off your Pod 5 Ultra through December 1st. Electricity bills have been climbing across the US, but the AI boom is making it worse. A lot worse. New data centers are popping up everywhere to handle ChatGPT, Gemini, and countless other AI tools. And here's the kicker: you're helping pay for them whether you use AI or not. In Columbus, Ohio, residential customers saw their bills jump by $27 a month this summer. Philadelphia went up $17. Washington D.C., $21. You may not be using more power, but utilities are building massive infrastructure for data centers and passing those costs onto you. How much is this AI blitz really costing us? And what can we actually do about it?

Have We Finally Solved The Plastic Problem? Go to https://surfshark.com/undecided or use code UNDECIDED at checkout to get 4 extra months of Surfshark VPN! What if every piece of plastic waste, like bottles, bags, even clothes, could be rebuilt from scratch, no sorting required? Not just melted and reshaped, but broken down to pure chemical building blocks and made new again. That's what a new wave of recycling tech promises. Northwestern University has built a catalyst that can zero in on a single type of plastic in mixed waste and break it down. No sorting, no problem. In South Korea, a 2,000°C hydrogen plasma torch is cracking mixed plastics in milliseconds, turning them into valuable building blocks for brand-new plastics. And in France, an enzymatic recycling plant is transforming previously unrecyclable polyester textiles back into virgin-quality plastic feedstock. We've been sold the recycling dream for decades, but the reality? Most plastic still ends up in landfills or the ocean. Could these breakthroughs finally turn recycling from marketing lie into working reality?

Solid-State Batteries: Hype vs. Reality. Take your personal data back with Incogni! Use code UNDECIDED at the link below and get 60% off an annual plan: http://incogni.com/undecided You've heard the solid state battery story before. Toyota promised them by 2025. Samsung said they were just around the corner. QuantumScape's stock soared on promises of revolutionary batteries. And yet here we are, still driving cars with the same lithium-ion tech. And if the sliding deadlines weren't enough of a headache, the term solid state battery has become a marketing buzzword. But 2025 might actually look different. Companies aren't just filing patents anymore. They're opening factories. They're putting innovative new batteries in actual vehicles. Mercedes just drove 749 miles on a single charge with one. MG is taking pre-orders for a car with a semi-solid-state battery for under $15,000. So is this finally it? Are solid-state batteries finally here? Or are we just being sold another round of hype?

How My Geothermal Heat Pump Really Performed (2 Years). Go to https://surfshark.com/undecided or use code UNDECIDED at checkout to get 4 extra months of Surfshark VPN! I’ve had my geothermal heat pump for the past two years now. It’s been helping me to reach my net zero energy goals in my new house. But getting it installed meant drilling a 400-foot-deep well in my backyard, running a cooling loop into the house through the foundation, and getting everything hooked up inside the house. It’s a little more complicated than your standard air source heat pump setup … and a lot more expensive, too. But was it worth it? I’ve learned a lot over the past two years, and I’ve collected a bunch of data, too. So what can you take away from my experience? And is there anything I’d change if I had it to do over again? Let’s dig into it.

The Surprising Battery Discovery No One Saw Coming. Take your personal data back with Incogni! Use code UNDECIDED at the link below and get 60% off an annual plan: http://incogni.com/undecided We've been told for years that fast-charging kills batteries. But what if that rule is wrong? The Georgia Institute of Technology just found that the faster they charged a zinc-ion battery, the better it performed. A damaged battery even started healing itself. And another team has re-engineered the atomic twists that normally break a zinc-ion battery down… to make it stronger than ever. These aren't just lab curiosities. Zinc batteries can act as a safer, cheaper alternative to lithium for grid storage and home use. They can't catch fire. They're made from abundant materials. But they’ve had one fatal flaw that’s kept them from dethroning lithium: they don’t last long enough. So, how did scientists turn atomic jitters into resilience? How can fast-charging help a battery perform? And what does it mean for all of us?
