Europe is preparing for a solar eclipse that will darken countries from Greenland to Turkey. With 3 percent of Europe's electricity grid now powered by solar, there is some concern that the eclipse could lead to grid problems and blackouts. It's a backward compliment to just how important solar has become for the continent in a very short period of time.
Here is an excerpt:
Next month's solar eclipse could be more than a spectacular natural phenomenon, with operators warning it posed an "unprecedented test" for Europe's power supplies.
The eclipse is due to take place on March 20 and marks the first time that Europe's solar-energy use has been significant enough to disrupt its grids, the European Network of System Operators for Electricity (ENTSOE) said Tuesday.
