What About Community Solar?

Offshore Wind & Ocean Energy

Ocean Energy

Ocean energy—specifically tidal and kinetic wave power—represents a promising, underutilized frontier in Oregon’s renewable energy landscape. Unlike solar or wind, these marine energy sources offer predictable, consistent output based on the natural rhythms of tides and currents. With Oregon’s dynamic coastline and strong tidal flows, especially near estuaries and headlands, there is real potential to harness kinetic energy from waves and tidal streams to generate clean electricity year-round. These systems can be deployed at smaller scales to support coastal microgrids, improve resilience during grid disruptions, and help rural or tribal communities move toward energy independence. As research institutions and marine developers refine technologies, community partnerships will be key to ensuring that this next-generation resource is developed sustainably—with minimal ecological disruption and maximum local benefit.

Biomass – Geothermal – Hydropower

Biomass

Biomass energy is created by converting organic materials—like wood waste, agricultural residues, and even certain types of garbage—into heat or electricity. When these materials are burned or biologically processed, they release stored chemical energy originally captured from the sun via photosynthesis. This energy can power turbines or generate heat directly for industrial or home use. Biomass is often considered carbon-neutral when sourced sustainably, because the carbon dioxide released during combustion is roughly balanced by the carbon absorbed during the plant’s growth. However, sustainable sourcing, emissions control, and forest health are critical factors in ensuring biomass remains a truly renewable and environmentally sound solution.

Geothermal

Geothermal energy taps into the natural heat stored beneath the Earth’s surface, using that thermal energy to generate electricity or provide direct heating. In geothermal power plants, wells are drilled into underground reservoirs to bring hot water or steam to the surface, where it spins turbines and generates electricity. For residential or commercial heating, shallow geothermal systems—known as ground-source heat pumps—use the steady temperature of the earth just below the surface to heat and cool buildings efficiently year-round. Because geothermal energy is available 24/7 and emits virtually no greenhouse gases, it offers a stable, low-carbon complement to solar and wind in a diversified clean energy grid.

Hydropower

Hydropower harnesses the kinetic energy of moving water—typically from rivers, dams, or even ocean currents—to generate electricity. As water flows through a dam or diversion channel, it spins turbines that activate generators, producing a steady and controllable supply of power. In Oregon and the broader Pacific Northwest, hydropower has long played a foundational role in the regional grid, providing renewable baseload electricity that supports millions of homes and businesses. While hydropower is a mature and efficient technology, its impacts on fish migration, ecosystems, and tribal water rights require ongoing attention and adaptive management to ensure it remains a responsible and equitable part of our clean energy portfolio.
