The Globe Foundation forecast assumes that B.C.’s population increases by 30 percent by 2025, raising demand for energy by 20 percent. It also assumes higher oil prices and the development of solar, wind, biomass, geothermal and tidal energy resources, plus development of a major dam and coal-gasification infrastructure.
