About

Most writing about renewable energy is either marketing or policy commentary. This site is neither. It explains mechanisms: why a solar cell produces roughly half a volt whatever its size, what a bypass diode actually protects, why a heat pump can deliver more heat than the electricity it consumes, and what the readings on a meter are telling you.

Every article starts from the same question — why does it behave this way? — and answers it with the physics, then follows that physics out to the practical consequences. If an article cannot explain the mechanism, it does not get published.

• No product reviews, comparisons or brand recommendations. We compare technologies and chemistries, never products.
• No prices, cost estimates or payback calculations. They vary by market and by month, and they age badly.
• No country-specific regulations, incentives or grid rules. They differ everywhere and change often.
• No installation instructions for work that needs a qualified professional. Understanding how something works is not the same as being equipped to work on it.

The result is narrower than a typical energy site and considerably more durable. What is here should still be correct in ten years.

Articles are researched and reviewed by the site’s editorial team against primary engineering and physics references. Every article carries the date it was last reviewed, and the review is a real one: the claims are checked again against their sources, not just the wording tidied.

The rules we hold ourselves to — how sources are chosen, what happens to a number we cannot verify, and how corrections are handled — are set out in full in our editorial policy.

The audience is international, so every measurement appears in both metric and imperial units. Temperature differences are given in kelvin where the physics calls for it, and absolute temperatures in degrees Celsius with a Fahrenheit equivalent. Nothing assumes a particular country’s wiring, climate or rules.

The site is free to read and carries no paywall. It is intended to be supported by advertising. No advertising runs on the site today; when it does, it will be clearly distinguishable from editorial content, and advertisers will have no influence over what is written or how it is written.

We do not accept sponsored articles, paid placements, affiliate arrangements or product samples. If that ever changes, it will be disclosed here first.

Corrections are the most valuable thing you can send us, and they are read first. Use the contact page, or write to hello@wattcurious.com.
