This visualization shows the energy resources used to produce electricity in the Northwest from 1960 to 2022 (filter by year using dropdown menu in upper right-hand corner).

Exploring historical changes in resources used to produce electricity reveals the emergence of renewable energy resources—biomass, wind, and solar—that join hydroelectricity over the past 20 years. The visualization also shows decrease of coal and the dominance of hydroelectricity in the Northwest. The Northwest Electricity Generation visualization provides a map of where electricity is generated in the region. Note that the 2020 data reflect COVID-19’s impact on energy use and consumption.
