Renewable energy systems used to need subsidies to be competitive with the even more subsidized fossil fuel energy systems. Today, despite the fact that globally USD$5.2 trillion was spent on fossil fuel subsidies in one year, non-subsidized solar and wind are cheaper than fossil fuels. This is really impressive given the relatively small size of renewables being used over the last decade. With more solar and wind installations being built the economics of renewable energy is only getting better.
Perhaps nowhere is the push toward subsidy-free clean energy clearer than on arid expanses of Southern Europe. About 750 megawatts of subsidy-free clean-energy projects are expected to connect to the grid in 2019 alone, across Spain, Italy, Portugal and elsewhere — enough to power about 333,000 households, according to Pietro Radoia, an analyst at BNEF.
“The cheapest way of producing electricity in Spain is the sun,” Jose Dominguez Abascal, the nation’s secretary of state for energy, said last year.
