WattGenio is a site of tools and guides to understand the electricity in your home: how much each appliance uses, what’s behind your bill, what battery you need to get through a power cut, or how many solar panels you need. It’s also available in Spanish, and both versions say the same thing.
Why it exists
Electricity bills keep rising, power cuts are common in many countries, and more and more people are thinking about solar panels or batteries. The answers you find often come from someone selling something, or give numbers without saying where they come from. Here the maths is always in plain sight, so you can check it and decide for yourself.
How we work
- Our calculators use basic physics and data from official energy agencies, and explain it below each one.
- Every fact in our articles has its source listed at the end, with a link, so you can check it.
- If a figure is for a specific country or year, we say so. If something changes, we correct it and the page shows the date of the last update.
- We don’t sell appliances or installations.
Who writes
Our articles are signed by the WattGenio Editorial Team, a small editorial team. We aren’t electricians or engineers, which is why we never give instructions for working on wiring: for any job on your breaker panel, outlets or fixed wiring, always call a qualified electrician.
