Foreign investment in solar and wind power dropped last year to €1.2 billion, one third the €3.7 billion of 2019, reported the State Energy Efficiency Agency. In 2019, investors from a dozen countries commissioned 4.5 gigawatts of renewables, racing to commission projects in time to win high green tariffs. But one year ago, the government started to fall behind on payments, running up an overdue bill now near $1 billion. Carryover projects accounted for most of the 2020 investment. Today, there are only a handful of new projects as investors wait for the government to honor its promise last summer to pay the bills.
