The sliders labelled basic are slightly confusing, especially as it's dimmed suggesting 'basic' is off.

Maybe a down arrow and advanced?

Also as a non USian without a zip code, this is fairly useless to me.

Thanks for the feedback! We can make those sliders better, thanks for the suggestions.

Yes, unfortunately we haven't seen great resources for the rest of the world, either. The same approach and core model here would work elsewhere, but we'll need to source historical data on housing stock, residential energy prices, grid emissions, weather to get it up and running elsewhere. If you know anyone that would be interested in taking that on, definitely let us know!
