Spanish Industry Minister Miguel Sebastian recently expressed his concern that most solar subsidies need to be paid for another 22 years. The subsidies, he said, were “fixed in years of bonanza, without taking into account that the more the sun shines, the more subsidies are paid.” Renewable tariffs need to be sustainable and shouldn’t endanger the competitiveness of Spain’s industry, he says. But Spain isn’t the only country in trouble, although it is considering the most-radical solutions. Other European countries find their subsidy regimes increasingly unaffordable, putting in jeopardy both investors’ capital and ambitious green goals.
