Yes but it's a lie of sorts. It's only reduced at the local level in some specific places on earth. What's more the local reduction has NECESSARILY been linkend to an increase in fossil fuel use to actually build, transport and install the panels.
That's not even talking about the energy used for extraction of the primary ressources used to build the stuff.
Until we can figure out how to use solar to actually power the industrial processes necessary to build/recycle/maintain it, it's mostly a lure, a stop gap at best. And to be able to do that you would need to have an industrial policy with strong rules inside the countries using the solar.
But it's all very convenient to lie about it, as if we are doing something meaningful, it's part of the inbuilt duplicity omnipresent in today's society, that derive from female virtuous posturing/behavior.
And as the parent noted, in the case of reduction of fossil fuel use that is necessary at the global level because the effect of climate change is not localized, solar doesn't meaningfully change anything yet. In fact, it allows us to just consume more energy while still putting out as much CO2 as before and actually even more. Global fossil fuel consumption has not reduced one bit; it's extremely hypocritical to have various countries around the world increase their consumption to be able to say that there was a decrease at some specific localisation.
