Since the early 2010s, wildfires in California are growing more dangerous because of the accumulation of wood fuel in forests, higher population, and aging and often poorly maintained electricity transmission and distribution lines.
United States taxpayers pay about US$3 billion a year to fight wildfires, and big fires can lead to billions of dollars in property losses.[9]
At times, these wildfires are fanned or made worse by strong, dry winds, known as Diablo winds when they occur in the northern part of the state and Santa Ana winds when they occur in the south.
The much larger wildfire seasons in the past can be attributed to the policy of Native Californians regularly setting controlled burns and allowing natural fires to run their course, which prevented devastating wildfires from overrunning the state.[10]
There are conservation issues that aren't allowing as many controlled burns necessary to lessen the damage for when a wildfire starts.[
