ABU DHABI: The share of renewables in the global energy mix has increased over the past decade to more than 15 percent but doubts remain over whether a 2030 target of 30 percent is achievable, delegates to an international conference said Wednesday.
Fossil fuels still account for 80 percent of world energy use, threatening efforts to reduce greenhouse gas emissions that are blamed for global warming, delegates said.
“The shift toward low carbon energy has started,” the executive secretary of the U.N. Framework Convention on Climate Change, Christina Figueres, told the World Future Energy Summit. “But it is not happening at the scale or speed required.”
The secretary-general of the International Renewable Energy Agency (IRENA), Adnan Amin, told the conference that if nothing was done, “we will have a 9-percent gap” on the 2030 target.
“We have to bridge this gap and we can,” said Amin, referring to an action plan released by the agency Monday.
Based on the Global Futures Report 2013 by the Paris-based Renewable Energy Policy Network for the 21st Century, renewable energy currently accounts for about 17 to 18 percent of the world energy mix.
Fossil fuels – oil, natural gas and coal – still account for a massive 80 percent while nuclear energy accounts for around 2-3 percent.
The report, based on interviews with 170 specialists, gave a wide range of projections for future renewables use.
The most conservative was that the share of renewables would not exceed 20 percent by 2050. Other specialists predicted a share of between 30 and 45 percent, while the most optimistic said clean energy could make up anywhere between 50 and 95 percent.
At present, renewables account for at least 20 percent of the energy mix in at least 30 countries, and around 120 countries have various types of policy targets, the report said.
“I am not optimistic that the 2030 goals will be achieved. I have many question marks,” said Fatih Birol, chief economist and director of global energy economics at the International Energy Agency. He said the average price for oil in 2012 was $112 a barrel, an all-time high.
