Decarbonization

Note from the editor

Governments, utilities and other companies are setting increasingly ambitious targets for reducing carbon emissions in order to reduce the risks of climate change.

This is prompting a range of significant challenges, from how to reliably integrate growing volumes of renewables to how to best transition former coal plant workers. Utilities are also finding that organizational change is needed to advance decarbonization.

The following trendline focuses on a variety of issues surrounding power sector decarbonization, from a broad national perspective to a regional case study and some resource-specific analyses.
