The efficient use of energy saves the consumer money, and reduces the need for developing new (and often more expensive) sources of energy. This element addresses energy conservation through a variety of land use planning and construction practices.

While no known sites that have a potential for oil, gas or geothermal resource development exist in the area, there are two hydroelectric sites within Bend. As early as 1910, a small hydroelectric dam was constructed on the Deschutes near downtown to generate power for the growing community. This facility is still in use today. In 1985 the Central Oregon Irrigation District built a hydroelectric facility using water from its irrigation flume along the river to power a small generating plant that is tucked into the hillside opposite Mt. Bachelor Village. In addition, there is still potential for heating and power from locally generated wood wastes, such as slash and mill trimmings. As noted earlier in the Air Quality section, Bend has an active program to upgrade wood stoves for more efficient use of the resource and to maintain air quality in the area.

The large number of sunny days makes this area particularly suitable for solar power, both passive and active systems. During the summer, 300-350 British Thermal Units (BTUs) of sunlight energy are delivered to each square foot of land in the area, but this level declines to 175-200 BTUs during the winter. Bend was one of the first cities in the state to adopt “solar access” ordinances to provide good solar access during the winter solar heating hours so that homeowners can incorporate passive or active solar systems into their homes.

The Bend area is fortunate to have some potential energy sources. However, the expanding population will continue to test the ability of energy suppliers to meet increasing demand. All available resources will have to be evaluated, used, and made compatible with the economic, social, and environmental goals of the local and regional population. No single answer exists, but a reasonable combination will have to be found. In the meantime, local planning efforts must be aimed at promoting greater efficiency in the use of existing energy resources, and in protecting and developing those resources we will need in the future.
