Other renewable sources In partnership with the private sector, energy development from renewable sources will be pursued, including geothermal, wind, and biomass. A considerable amount of investment will be required to produce energy and electricity generating capacity from these other sources where feasible, but importantly there is great potential because they can produce electricity at low cost. By 2030 around 25 per cent of PNG's electricity needs will be generated from these renewable sources. In addition, biofuels will be developed as a renewable energy alternative to fossil fuels for transport. 4.12. Rural development
