    • Biofuel potential in Southeast Asia: Raising food yields, reducing food waste and utilising residues

      Southeast Asia has considerable resources to produce liquid biofuels sustainably, using biomass feedstocks that would not cause carbon-dioxide emissions or interfere with food supply. This report offers detailed estimates of biomass resource potential for Indonesia, Malaysia, the Philippines, Thailand and Viet Nam. According to an IRENA assessment, advanced biofuels could provide as much as 7.3 exajoules of primary energy per annum in Southeast Asia by 2050, or half of the region’s total primary bioenergy potential.

    • Renewable Energy Options for Shipping

      The shipping industry plays a critical role in the global economy, carrying approximately 90% of the total tonnage of world’s traded goods. Shipping propulsion has changed radically since the mid-19th century, from the renewable energy of sail power, to the coal power of steamships, to the predominance of heavy fuel oil and marine diesel oil. But renewable energy technologies could transform the global shipping fleet again, at all levels and scales.
