The analysis of all scenarios shows that the biggest share of energy supply technologies in 2050 comes from renewables according to the new Energy Roadmap 2050 of the European Commission published on 15 December 2011.
Many renewable technologies need further development to bring down costs. There is a need to invest in new renewable technologies, such as ocean energy and concentrated solar power and 2nd and 3rd generation biofuels.
The International Energy Agency (IEA) published the Technology Roadmaps - Biofuels for Transport.
“Biofuels could provide up to 27% of total transport fuel worldwide by 2050. The use of transport fuels from biomass, when produced sustainably, can help cut petroleum use and reduce CO2 emissions in the transport sector, especially in heavy transport. Sustainable biofuel technologies, in particular advanced biofuels, will play an important role in achieving this roadmap vision.
The roadmap describes the steps necessary to realise this ambitious biofuels target; identifies key actions by different stakeholders, and the role for government policy to adopt measures needed to ensure the sustainable expansion of both conventional and advanced biofuel production.”
