Solar power expected to dominate electricity generation by 2050—even without more ambitious climate policies::In pursuit of the ambitious goal of reaching net-zero emissions, nations worldwide must expand their use of clean energy sources. In the case of solar energy, this change may already be upon us.

There was a time early in the electrification of America with Edison, he pushed for DC over AC. https://en.wikipedia.org/wiki/War_of_the_currents

The last DC utility turned off in 2007. http://www.jaygarmon.net/2010/11/in-what-year-did-last-of-new-yorks-dc.html

As far as answering your question, you can run a transformer, but new construction and new appliances will likely be built with DC service in mind.

Most things with a motor would prefer AC. Alternatively, they use DC, but it's a brushless motor with more complicated electronics and are more expensive for it. This would apply to anything with a heat pump, which includes air conditioning and hybrid water heaters.

Things that run electric resistive heating is fine with either AC or DC, but it has to be higher voltage. The benefits of DC disappear because nothing wants to run at the same voltage.
