What they cover
Just Have a Think (Dave Borlace) produces weekly explainers on clean energy technology, climate solutions, and engineering innovations. UK-based, with a calm, engineering-focused presentation style. Topics cover battery chemistry, hydrogen, nuclear, grid storage, carbon capture, and sustainable materials. Each video includes cost analysis and scalability assessment.
Why they matter
Borlace provides the engineering rigor that emotionally driven climate content often lacks. His weekly cadence means the channel tracks emerging technologies in near real-time: when a new battery chemistry is announced, he has a video explaining the science, cost implications, and scalability within days. For investors, policymakers, and engineers who need technically accurate, jargon-accessible climate tech analysis, this is the most consistent source on YouTube.
