DTE Energy has set a goal of being 100 percent carbon-neutral by 2050.
But the company's Trevor Lauer said the path to 100 percent will require technologies that aren't widely available now.
“We’re going to work on technological advances that we see coming in the future, things like carbon capture and sequestration, storage technologies, and even advanced modular nuclear.”
One critic isn't impressed.
Margrethe Kearney is with the Environmental Law and Policy Center.
She said DTE's goal is great; but she says the utility could and should take steps now to reduce carbon emissions more swiftly.
Those include battery storage, more solar energy and energy efficiency, and reducing demand for electricity.
