Yes they are still heavily subsidized, but according to Lazard's Levelized Cost of Energy Analysis utility-scale solar and wind are lower cost ($/MWh) than most other forms of electricity generation, even when unsubsidized. That has been true since at least the 2016 version of the report (check out the chart on page 2). In the 2023 version this is still true.

Wind power in particular is just ridiculously cheap to install and operate, which is why there have been so many new installations over the past decade. Spending money on any other new power generators just looks financially irresponsible at this point. I think this is part of why new nuclear projects keep dying - they get more expensive while wind and solar get cheaper.

Unfortunately, in comparison rooftop residential solar looks like a bad investment.

So yes, wind and solar are still subsidized because the government wants to encourage their use, but they don't have to be subsidized to be competitive in the energy market.
