The amount of renewable energy on the national grid changes minute by minute, depending on things like the weather. As it changes, so does the amount of CO2 we all emit. We have little choice when to turn lights or oven on, but for things like a dishwasher, washing machine or even an electric car, running at a greener time can add up to a big difference.
Just ask Bulb when the best time to use energy is, and we'll give you the best window, up to 48 hours ahead, using predictions from Carbon Intensity API and the National Grid.
