The REN21 multi-stakeholder network released its latest report on the feasibility and challenges of achieving a 100% renewable energy future on 3 April 2017. 
Report key findings include: 
•    More than 70% of the experts interviewed consider a global transition to 100% renewable energy to be both feasible and realistic, with European and Australian experts most strongly supporting this view.
•    There is an overwhelming consensus that renewable power will dominate in the future, with many noting that even large international corporations are increasingly choosing renewable energy products either from utilities or through direct investment in their own generating capacity.
•    Numerous companies, regions, islands and cities have set 100% renewable energy targets.
•    Nearly 70% of those interviewed expect the cost of renewables to continue to fall, beating all fossil fuels within 10 years’ time. Wind and solar photovoltaic are in fact already cost-competitive with new conventional generation in most OECD countries. 
•    Countries as diverse as China and Denmark are demonstrating that GDP growth can be decoupled from increasing energy consumption.
    The report also identified a number of challenges, however. In some regions, most notably Africa, the US and Japan, experts were skeptical about reaching 100% renewable energy supply in their own countries or regions by 2050, largely due to the vested interests of the conventional energy industry. 

More than 90% of the experts interviewed agree that renewable energy technologies serve to lower the barrier for communities to gain access to energy services. An estimated 100 million people now receive electricity via distributed renewable energy systems, and markets for such systems are growing rapidly. 
    The lack of long-term policy certainty and the absence of a stable climate for investment in energy efficiency and renewables hinder development in most countries.
    Arthouros Zervos, Chair of REN21, said: “When REN21 was founded in 2004, the future of renewable energy looked very different than it does today. Back then, no one could have imagined that in 2016 China would become the renewable energy powerhouse of the world; and that more than half of global renewable energy investment would take place in emerging economies and developing countries. At that time, calls for 100 % renewable energy were not taken seriously, today the world’s leading energy experts are engaged in rational discussions about its feasibility, and in what time frame.”

The research for the report was conducted under the leadership of the University of Technology Sydney.
