Electrical energy is always in balance. Saying that 97% of Scotland's electrical energy needs were met by renewables is highly misleading because it ignores the most important piece of context - time.

Scotland could have generated 300% of daily energy demand from wind one some days. And zero on others. The reality is that one cannot be subtracted from the other to claim that net consumption is zero precisely because there is a time when that is not true.

Electrical energy is not like balance of trade i.e. it is not fungible. There is a further complication here - the assumption that there is a ready sink of generated energy. If that stops being the case, then suddenly those days of 300% demand being generated are no longer possible.

The headline is a mischaracterisation and is misleading.
