If you increase your consumption of energy at a time when average emissions intensity is low, you’re not necessarily doing a good thing for the environment

A quick note about the need to avoid focusing on average emissions intensity (for the wrong reasons) and losing sight of the fact that it’s the emissions intensity of the next marginal unit of production that should be used for making short-term consumption decisions (if the objective is reducing your environmental footprint, as an energy user).

Some initial musings about my own Rooftop Solar Learning Exercise

There’s already been a large uptake of distributed energy generation data, and there promises to be much more to come in this energy transition. With this comes some significant challenges – along with opportunities (with respect to the electricity production itself, and also in terms of the data that’s produced). So in the interest of doing things better, here’s a detailed look at our own rooftop solar experiences at home.
