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.
