Spain's blackout had nothing to do with renewables Red Eléctrica miscalculated dynamic voltage capacity needed. Regulator should have switched on another thermal plant Plus, private generators failed to regulate grid's voltage shortly before blackout bbc.com/news/articles/…

Republicans have no prob ending solar+wind tax credits, but Dems, when in charge, never end fossil or nuc benefits When Dems take control, they should eliminate all tax benefit of fossils+nucs Solar stocks dive. Senate wants to end wind+solar tax credits msn.com/en-us/money/ma…
