6 FAQs about [Southern drought and solar power generation]
How do solar droughts occur?
Solar droughts occur via two key drivers: high energy demand or low energy supply. From 1985 to 2014, 66% of global solar droughts are driven by high energy demand, while only 34% are driven by low energy supply. These two types of solar droughts show large differences across regions.
Is solar power a 'drought'?
Solar power is an important clean energy source that supports ambitious global carbon-neutrality goals. Yet, its supply is well known to be affected by weather fluctuations (Gernaat et al., 2021; Jerez et al., 2015; Poddar et al., 2021; Sawadogo et al., 2021), leading to the concerns of solar “droughts”.
Are wind and solar droughts a threat to power systems?
Wind and solar droughts pose serious risks to systems relying on renewable resources; identifying and characterizing these threats can provide essential information for achieving power system reliability.
How do wind and solar energy droughts affect climate and weather?
