TOKYO -- Sumitomo Corp. has joined geothermal power projects in Indonesia designed to eventually generate 400 megawatts worth of electricity, a small step toward the trading house's long-range goal of deriving 30% of its total power output capacity from renewable sources.
If the projects go well, Sumitomo intends to use them as steppingstones into the geothermal power generation business in the Philippines and the U.S.
