Probably the most difficult challenges of a 100 % renewable energy grid is tips on how to exchange the inertial stability supplied by the spinning turbines that the trendy grid is constructed to serve.

The kinetic vitality of those large rotating machines works like a shock absorber to maintain grid frequency from dropping too quick when demand exceeds provide or rising too quick when provide exceeds demand. With out this stabilizing power, energy grids may face higher threat of frequency excursions that might power turbines offline, or trigger cascading outages just like the 2003 blackout that affected about 50 million individuals throughout the Northeast U.S. and Canada’s Ontario province.
