Current Issues

Radioactive Waste

Radioactive Waste

Safe storage of high level radioactive waste is the Achilles’ heel of the nuclear industry. The waste must be stored and isolated from the environment for a million years.

After decades of failed policy, there exists no environmentally safe, just, and equitable solution to the storage of high level radioactive waste.

Diablo Nuclear Plant

Decommissioning or Extended Operation?

Diablo Canyon nuclear plant was scheduled to retire in 2024 and 2025 through a 2016 joint agreement between its owner, Pacific Gas and Electric Company (PG&E), labor, consumer advocacy and environmental groups. However, over the last year, there has been a push to extend operations beyond these shutdown dates based on Governor Newsom’s claim that its energy is needed. 

Climate and Energy

Climate and Energy

San Luis Obispo Mothers for Peace (MFP) recognizes the threat to all life forms on the planet posed by the increase in carbon dioxide.  Human activities, especially since the industrial revolution, have caused this climate change. MFP works in conjunction with like-minded organizations to preserve a livable world for future generations.
