No, directed energy weapons did not start the Texas wildfires

After wildfires broke out in Texas, the largest in the state’s history, a familiar conspiracy theory began circulating online: Social media users are claiming the blaze was set intentionally using "directed energy weapons."

A March 3 Instagram post shared side-by-side videos of a purported "directed energy weapon" attack and the Texas wildfires. The video on the left showed what appeared to be a flash of lightning with a green laser beaming down behind a house at night. The video on the right showed a Texas landscape covered in smoke and fire.

The video’s text says, "Could these two events be related?"

Other Instagram posts also shared the green laser video and suggested it was related to the Texas wildfires.

One post’s caption read, "If this is actual footage … we’re looking at yet ANOTHER intentionally set fire courtesy of DEWS (directed energy weapons) and our lovely (government)."

Some X posts shared a clip of President Joe Biden discussing the Texas wildfires and claimed he said directed energy weapons were involved. We previously fact-checked social media posts that took this clip of Biden out of context. The president was discussing the need for buildings to be up to code to better withstand wildfires.

In the week since fires broke out across the Texas Panhandle, more than 1 million acres of land have burned, and at least two people have been killed. The fires have also killed thousands of livestock animals, scorched fields of crops and destroyed hundreds of buildings.

Directed energy weapons are real and fire concentrated electromagnetic energy at light speed. Such weapons include high-energy lasers, high-power microwaves and radio frequency devices. The United States and other countries are researching using directed-energy weapons for military purposes, but there is no evidence they were used to ignite the Texas wildfires.

Authorities are still investigating how the Smokehouse Creek fire, which still burns, started. A Texas homeowner sued a utility company, blaming a downed power line, but officials have not determined a link. Hot weather, dry land and high winds have fueled the fire’s spread.

The green laser beam video predates these Texas fires. Reverse-image searches using Google Images found this video was shared online as early as Dec. 31, 2023. The account that appears to have first shared it is known for videos that claim to show paranormal or extraterrestrial activity.

Last year, social media users also claimed that directed energy weapons ignited fires that devastated Maui, Hawaii. There have been similar claims about fires in Canada and Russia. But all these claims are unfounded.

We rate the claim that the Texas wildfires were started by directed energy weapons False.
