Laos hydro dam collapses while under construction with the possible deaths of hundreds

In Laos, a hydroelectric dam that was under construction has collapsed. Hundreds of people are missing and many are likely dead. Rescue efforts were underway as top government officials rushed to the site and public appeals were launched for aid.

The hydroelectric dam collapsed in southeastern Laos, leaving an unknown number of people dead and hundreds missing, state media said on Tuesday. Rescue efforts were underway as top government officials rushed to the site and public appeals were launched for aid.

Laos exports a lot of electricity from several hydroelectric dams. Thailand is a major buyer of this electricity.

The Xepian-Xe Nam Noy project cost an estimated US$1.02 billion. Much of the financing came from Thai lenders.

Deaths per Terawatt hour

This tragedy does not shift the global death per terawatt hour calculations much. The statistics that Nextbigfuture has provided on this over the years need to be updated with significantly more power generation for solar and wind. Also, there have been updates to the deaths attributable to air pollution.

The Natural gas air pollution needs to have the 1.6% or higher leakage from pipes and mining accounted for its impact.
