Hawaii is receiving its final shipment of coal this week, which Gov. David Ige called a huge step forward in the state’s transition to clean energy. What he meant was that local are about to pay a lot more for basic essentials.

A law put in place a couple of years ago will finally shut down the island’s last coal burning power plant. And since coal is the dirtiest * but cheapest – source of power for Oahu, it means that all else equal, power prices are about to skyrocket.

“In its time, coal was an important resource for Hawai‘i and I’d like to thank the workers who have run our last remaining coal plant,” Ige said in a statement. “Renewable energy projects to replace coal are coming online with more on the way.”

“Even as we face challenges in making this transition, it’s the right move for our communities and planet. Most importantly, it will leave Hawaiʻi a better place for our children and grandchildren.”
