Electricity and power make up around 20% of global use, with manufacturing taking a portion of the pie closer to 30%. Migrating those systems is a very large hurdle, but I'll admit that whilst doing some investing around this recently, it seems to be a clear target by many organisations. Migrating traditional manufacturing processes for chemicals and base materials is going to have a massive impact on the overall situation.
In saying all this, the idea that we will be anything close to decarbonised by 2030 is a joke of epic proportions, the scale of the problem is mind boggling. Not that that means we shouldn't try, as it's a very necessary goal. But I actually think being more realistic about the scale of the issue is more likely to generate more interest in crafting fixes, as opposed to these bullshit goals that in many ways, make the problem sound solveable within the timeline. Which it isn't.
