The sun could be our biggest single source of energy and prevent 6 bilion tonnes of climate-warming CO2 pollution by 2050, according to two new reports.
Issued by the International Energy Agency, the two “Technology Roadmap” reports conclude that solar photovoltaic (PV) systems could supply 16% of the world's electricity needs and concentrating solar power (CSP) plants could provide another 11% by the mid-point of the 21st century.
Underscoring these findings, IEA Executive Director Maria van der Hoeven says, “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 in the coming years and decades.”
To get there, however, the reports warn that “clear, credible and consistent signals from policy makers” must be provided in order to inspire confidence in investors, as both PV and solar thermal electricity technologies like CSP require big up-front capital expenditures.
“Lowering the cost of capital is thus of primary importance for achieving the vision in these roadmaps,” Van der Hoeven adds.
