Customer Reviews

Great, illuminating app

Gridwatch is a really clean simple app, but also has depth. It was very illuminating to see how how CO2 production is effected by increases in demand and the changes to the power production sources that result from it. It's also fun to play with. It's clear that a lot of work was done in designing the app. It feels clean and simple, but there is a lot of information here.

Very Informative

Very informative and surprisingly addicting. I find myself quizzing family and friends about the sources of hydro here in Ontario all the time.

Amazing Resource

Good bye coal! Hello sunshine & biofuel!! Love every update, I just hope the next one shows us less oversupplied... that might be outside of the developers control.
