Solar power might become the world’s largest source of electricity by 2050 as falling costs boost installations, according to the International Energy Agency.

Photovoltaic plants may provide as much as 16 percent of global electricity, and concentrating solar facilities could generate another 11%, the IEA said in an e-mailed statement. The Paris-based organization details what is required to reach these figures in two scenarios it sets out to reach the goal.

“The rapid cost decrease of photovoltaic modules and systems in the last few years has opened new perspectives for using solar energy as a major source of electricity,” Executive Director Maria van der Hoeven said.

The technologies are expensive to develop, so lowering the cost of capital is of primary importance to achieve this vision, she said.

The IEA is the latest organization to suggest the potential of renewable energy, particular solar, to transform the global power system. Solar power will take a bigger share of the energy market shake up the industry by 2030, with panels reaching a 6 percent share of electricity from 0.3 percent now, Bloomberg New Energy Finance forecasts. Solar plants and batteries will be disruptive technologies for the power system, UBS AG said last month.
