Wind turbines and photovoltaics (PVs) are becoming increasingly widespread worldwide, which could contribute to reducing air pollution caused by fossil fuel emissions. To produce energy, however, these renewable energy solutions rely on specific weather conditions (e.g., the presence of wind and sufficient hours of sunlight).
OF course they’re more prone to blackouts, and what the study says is that they’re less likely to cause severe blackouts than traditional power systems, because they’re distributed so that reduces the likeliness; and grids rely on other systems as baseline anyway.
