Labels:text | font | screenshot | white OCR: Finland's trees are its prime natural resource. Commercial forests cover 65% of the land and wood products account for 40% of exports. Finland has no oil, but has significant hydroelectric resources. Industry's high energy demands are met primarily by thermal and nuclear power. A fifth nuclear power station is planned. Oil import costs have risen since 1990, when the collapse of the USSR ended a 42-year agreement on the exchange of Finnish manufactures for Soviet oil.
