The title is somewhat misleading.

First, US demand increased by 3.1%. That is bad - demand should be going down, since there is a need to conserve electricity while much of it is provided by CO2-emitting sources. That said - it is not such a huge "surge" that the fact that 61% of it was covered by an increase in Solar capacity is so impressive.

Second, Solar generation is said to have reached 84 TW. But if the increase in demand was 135 TW, and that's just 3.1% of total demand, then total demand is 4355 TW, and Solar accounts for 1.92% of generation. That is _really_ bad. Since we must get to near-0 emissions in electricity generation ASAP to avoid even harsher effects of global warming; and most of the non-Solar generation in the US is by Natural Gas and Coal [1].

You could nitpick and say that the important stat is "total renewables" rather than just Solar, and that the US has a lot of Nuclear, and that's technically true, but it's not as though Nuclear output is surging, and it has more obstacles and challenges, for reasons. So, the big surge to expect in the US is Solar - and we're only seeing very little of that. If you mis-contextualize it sounds like a lot: "60% of new demand! 27% increase since last year!" but that's not the right context.
