As far as I understood, the left/green percentage is how much of the city systems (that affect this attribute) are up and running. So in your example it would mean that 66% of the citys energy production capabilities are running. The rest is still damaged or otherwise not capable of producing energy.
The right/red percentage is how much of the current demand you supply. In your example you supply 97% of the energy currently needed.
Once you supply the whole demand, the number turns blue. And your energy demand will raise as more and more systems get repaired and start running.

As for the components, my guess would be that the percentage is how much of the city component production facilities are running. The city creates components passively. Currently your city is using 62% of its theoretical component production capacity, because 38% of the component-producing districts are still damaged or nor supplied with energy.

In short, the formulas are:
Left number = current production / maximum production
right number = current production / current demand

Makes sense. Basically, the red numbers are helpful to understand which sectors you should prioritize when reparing them to achieve better performace. Not taking into account special functions, obviously.

I find the trendlines more useful than the red numbers. Generally, if the left number is higher than the right, things are improving.

I don’t think that’s correct.

Fake numbers to understand this (as i understand it at least, please correct me if i’m wrong)

If you have only 1 generator running out of 10, you have 10% Generator working. But, if each generator produce 50 Power, and your city needs 25 power to run, you don’t need 10 Generators (10*50 = 500 power), you only need 1 (50 power, covering the 25 needed). So, the green/left would be small (10%), but the red/right would be high (200%)

Green on the left is current percent restored. On the right, red indicates a deficit, Blue indicates satisfied needs. Current population and restored facilities shift both demand and supply of city resources. What I have found is life support cannot be met by fully restoring facilities. I believe a tech which turns pops into cyborgs may eventually allow you to get 100% demand for life support.

So for your question: You have restored 66% of maximum power, and are 2.89% below demand.
