(Bloomberg) -- California lawmakers are lining up against Governor Gavin Newsom's push to rewrite how the state assigns financial responsibility for wildfires sparked by equipment owned by publicly traded utilities.

California legislators introduced a bill Saturday that would update the state's wildfire response without shifting liability away from publicly traded utilities.

The California Assembly adjourned without passing a revamp of the state's wildfire response, sending up shares in two key power utilities, PG&E Corp. and Edison International.

PG&E Corp. plans to defer about $2 billion of work next year as part of a strategic review of its businesses, a move that comes after it said a proposed revamp of California’s wildfire response didn’t do enough to protect the company and its peers from the cost of such disasters.

As AI use shifts from simple, one-off queries to longer and more complex tasks, the added computing required results in a dramatically larger environmental footprint.

So far, scientists have pulled off energy-generating reactions only in laboratory settings, and the path there has been slow and costly. But companies say they’re getting rapidly closer to commercial viability.
