Biomass

Studies indicate that Oregon has excellent biomass resource potential. For more state-specific resource information, see Biomass Feedstock Availability in the United States: 1999 State Level Analysis.

Geothermal

Oregon has high-temperature resources that are suitable for electricity generation, as well as direct use and heat pump applications. For more information on geothermal resources, including resource maps, visit GeoPowering the West.

Hydropower

Oregon has a very good hydropower resource as a percentage of the state's electricity generation. For additional resource information, check out the Idaho National Laboratory's Virtual Hydropower Prospector (VHP). VHP is a convenient geographic information system (GIS) tool designed to assist you in locating and assessing natural stream water energy resources in the United States.

Solar

To accurately portray your state's solar resource, we need two maps. That is because different collector types use the sun in different ways. Collectors that focus the sun (like a magnifying glass) can reach high temperatures and efficiencies. These are called concentrating collectors. Typically, these collectors are on a tracker, so they always face the sun directly. Because these collectors focus the sun's rays, they only use the direct rays coming straight from the sun.

Other solar collectors are simply flat panels that can be mounted on a roof or on the ground. Called flat-plate collectors, these are typically fixed in a tilted position correlated to the latitude of the location. This allows the collector to best capture the sun. These collectors can use both the direct rays from the sun and reflected light that comes through a cloud or off the ground. Because they use all available sunlight, flat-plate collectors are the best choice for many northern states. Therefore, this site gives you two maps: one is the resource for a concentrating collector and one is the resource for a flat-plate collector.

What do the maps mean? For flat-plate collectors, Oregon has useful resources in most of the state, with the best resources falling in the eastern region of the state. For concentrating collectors, Oregon's resource varies significantly across the state. In the eastern region, the resources are useful for most technologies. Along the coastline, though, most concentrating collectors would not be effective.

The Renewable Energy Atlas of the West estimated the annual solar electricity generation potential in Oregon to be 68 billion kWh, based on the following assumptions:

Rooftop and open space installed systems represent 0.5% of the total area of the state.
Solar panels occupy 30% of the area set aside for solar equipment.
The average system efficiency is 10%.

Wind

Wind Powering America indicate that Oregon has wind resources consistent with utility-scale production. The good to excellent resource areas are concentrated on ridge crests throughout the state. In addition, small wind turbines may have applications in some areas. For more information on Oregon's wind resources including wind maps, visit Wind Powering America's Oregon Wind Activities.

The Renewable Energy Atlas of the West estimated the annual wind electricity generation potential in Oregon to be 70 billion kWh. The estimate excludes 100% of the following areas, which are assumed to be infeasible for wind development:

Landforms – land with a slope of greater than 20%.
Environmentally sensitive areas.
All National Park Service lands.
All fish and wildlife lands.
All Forest Service or BLM lands with "special" designations, such as national recreation areas or national wilderness areas.
All bodies of water.
Wetlands.
Urban areas.

Energy Efficiency

Energy efficiency means doing the same work, or more, and enjoying the same comfort level with less energy. Consequently, energy efficiency can be considered part of your state's energy resource base - a demand side resource. Unlike energy conservation, which is rooted in behavior, energy efficiency is technology-based. This means the savings may be predicted by engineering calculations, and they are sustained over time. Examples of energy efficiency measures and equipment include compact fluorescent light bulbs (CFLs), and high efficiency air conditioners, refrigerators, boilers, and chillers.

Saving energy through efficiency is less expensive than building new power plants. Utilities can plan for, invest in, and add up technology-based energy efficiency measures and, as a consequence, defer or avoid the need to build a new power plant. In this way, Austin, Texas, aggregated enough energy savings to offset the need for a planned 450-megawatt coal-fired power plant. Austin achieved these savings during a decade when the local economy grew by 46% and the population doubled. In addition, the savings from energy efficiency are significantly greater than one might expect, because no energy is needed to generate, transmit, distribute, and store energy before it reaches the end user.

Reduced fuel use, and the resulting decreased pollution, provide short- and long-term economic and health benefits.
