BP said in its annual Energy Outlook that renewable energy will grow faster than expected and will account for over one third of the growth in global power generation by 2035 . It predicted that renewables will increase by 6.6 % per year , resulting in a 9 % share of total primary energy mix . BP likened the surge in renewable power to oil’s growth at the beginning of the 20th century. Faster - than - expected technology cost increases and the anticipated government policies that will support low - carbon energy contributed to the company 's revised forecast for renewables growth to 14 % . Gas growth will slow by 0.5 % p.a . , to an all - time low of 25 % share of the primary energy mix , with gas becoming the world 's second largest fuel source .
