Renewable energy share of global electricity production in 2016 was 24.5% and PV share was 1.5 % (1.2% in 2015). The global capacity of PV has increased at a growth rate around 30% in the last decade and reached 303 GW at the end of 2016 (probably approaching 400 GW at the end of 2017). The cost of PV electricity has continuously come down to 2~3 US cents/kWh in MENA regions thanks to high solar irradiance.
