How does drought impact energy infrastructure?
Drought conditions can reduce the energy generated by hydroelectric dams due to low water levels in reservoirs. High temperatures, which often accompany and exacerbate drought, affect the energy supply chain, reduce biofuel feedstocks, and increase the risk of wildfires, which can impact energy infrastructure.
Does drought affect terrestrial water storage?
We found that regardless of the scenario, the cumulative effects of drought on terrestrial water storage significantly decreases in the dry zone, making the response of terrestrial water storage to drought increasingly sensitivity, while it shows an unstable oscillating state in the polar zone.
How does drought and water scarcity affect energy systems?
Drought and water scarcity directly affect energy systems due to their interdependence. All sources of energy require water in their production processes, and energy is needed to extract, convey, and deliver water. The availability and predictability of water resources can significantly impact energy systems.
How does drought affect power supply and demand?
On short time scales (e.g., diurnal), the reduction of hydropower during a severe drought may result in a deficit between power supply and demand especially during peak demand hours and therefore jeopardize grid stability.
Will global terrestrial water storage to drought be stable at high elevations?
We found that the stability of global terrestrial water storage to drought effect is highest at high elevations in the historical period and the Pre-Century of SSP126, while this is not the case in other scenarios, so the stability of global terrestrial water storage to drought at high elevations will be increasingly in the future.
Are there power plants in drought?
According to the U.S. Drought Monitor and data from the U.S. Energy Information Administration (EIA), there are U.S. power plants in drought. Reduced water supply can lead to reduced energy production and even temporary closure of energy facilities.
