For a third year in row, California is suffering severe droughts. As a consequence, the water level of Lake Oroville has decreased towards historic lows. This also leads to a significant decrease of available hydropower and California is forced to rely more on natural gas plants, resulting in more CO2 emissions.
Should have been photo of the week two years ago when it was taken. Almost back to normal today
