I interpreted “right now” in the message as “today”, or “when the post was made.”
Some days are purely renewable. Others aren’t. In the winter when electricity usage goes up it’s not uncommon for us to import fossil fuel electricity from other countries. The green party also suggested powering up natural gas plants as we were shutting down nuclear. Ngas obviously isn’t renewable.
Svenska Kraftnät has a “control room” with graphs and timelines on exports/imports and energy sources.
“Värmekraft” is power produced by burning things, it can be coal, oil, wood fuels, garbage, etc.
“Ospecifierat” (unspecified) includes power produced in facilities with more than one type of source, where you cannot separate what produces what.
