Case studies prepared by IRENA in collaboration with ICLEI (Local Governments for Sustainability) and the German Agency for International Cooperation (GIZ) review crucial aspects of the urban energy transition.
As the world strives to cut carbon emissions, electric power from renewables has emerged as a vital energy source. Fuel needs for transport and industry, meanwhile, could be met with renewable-based hydrogen.
This report, prepared jointly by IRENA, the IEA and REN21, identifies key barriers and highlights policy options to boost renewable energy deployment.
This report offers detailed estimates of the biomass resource potential in Ghana, Mozambique, Nigeria, South Africa and Uganda. With conversion to advanced liquid biofuels, sustainable biomass feedstock could potentially meet or exceed the five countries’ combined fuel needs for transport in 2050, according IRENA estimates.
Switching to biogas as vehicle fuel can reduce greenhouse gas emissions in the transport sector between 60% and 80% compared to fossil-based fuels like gasoline and diesel.
Developing and promoting biofuels for aviation will be essential to reduce carbon emissions from commercial aviation. As a first step, some pioneering airports have already incorporated bio-jet fuel into their refuelling systems..
The global stock of electric vehicles (EVs) reached 1 million in 2015 and exceeded 2 million by the end of 2016. Yet faster growth is needed for EVs to fulfil their role in the global energy transition, both through lowering vehicle emissions and boosting renewable energy use.
This report explores potential for urban communities to scale-up renewables by 2030, based on estimated energy use 3,649 cities around the world. By highlighting the best practices, it examines the policies and technologies by which cities can bring about a renewable energy future.
This working paper draws on engagement with a Transport Action Team of experts and expands on the transport-related findings published in IRENA’s report REmap: Roadmap for a Renewable Energy Future, 2016 Edition.
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...
