The left has no understanding of the role of market prices in matching supply with demand. To haughty elitists, central planners are wiser than the unorganized mob of buyers and sellers. So it should not surprise us that when environmentalists muck up electricity pricing schemes to promote solar power, mischief ensues.

After press reports,  it was established during inspections that several solar power plants were generating current and feeding it into the net at night. To simulate a larger installation capacity, the operators connected diesel generators.

"This is just the tip of the iceberg," said one industry expert to the newspaper "El Mundo", which brought the scandal to light. If solar systems apparently produce current in the dark,  will be noticed sooner or later. However, if  electricity generators were connected during daytime, the swindle would hardly be noticed.
