Top 250 oil and gas firms own just 1.5% of the world's renewable power

Despite public promises by many fossil fuel firms that they are investing in the green transition, it turns out that they have made little contribution to the growth of renewable energy

Leading oil and gas companies own less than 1.5 per cent of the world鈥檚 renewable power capacity 鈥 raising questions about how committed they are to the green energy transition, despite their public claims.

and at the Autonomous University of Barcelona looked at ownership records of more than 53,000 wind, solar, hydroelectric and geothermal projects worldwide, as tracked by Global Energy Monitor, a non-governmental organisation. They then cross-checked these to see what proportion of them were owned by the world鈥檚 250 biggest oil and gas companies, which are collectively responsible for 88 per cent of global hydrocarbon output.

Many fossil fuel firms have pledged to invest in renewable energy sources as the world attempts to transition away from oil and gas, but the researchers found that the top firms own just 1.42 per cent of the total operating renewable capacity globally. More than half of that 鈥 some 54 per cent 鈥 was owned via acquisitions, rather than companies developing their own projects. By calculating the total energy output of the 250 firms, the pair found that renewable power accounts for just 0.13 per cent of the energy produced by these companies.

鈥淭he results were surprising, even for me,鈥 says Llavero Pasquina. 鈥淚 knew they were playing a very little role in the energy transition. I knew it was only for show. It was only for dressing their narrative. But I didn鈥檛 expect this low number.鈥

Llavero Pasquina and Bontempi are both part of a group called , which aims to produce research to 鈥渟tudy and contribute to the global environmental justice movement鈥. Llavero Pasquina says his campaigning position strengthens his research. 鈥淵ou have the biggest interest in being as rigorous as possible, because you have to convince and you have to show what鈥檚 true.鈥

The fact that big energy firms, which have made their name and fortunes through oil and gas exploitation, aren’t massive players in renewables is unsurprising, says at Sciences Po in Paris. 鈥淎t the end of the day, [the energy transition] has to be something disruptive, and it鈥檚 not going to be in the hands of those companies.鈥

However, Bros does believe the big energy firms are unduly promoting their work on the energy transition. 鈥淭hey are portraying themselves [as] doing something, but I think if they were to do something, it would be more the carbon capture and sequestration,鈥 he says, which involves capturing carbon as it is emitted, for instance when burning fossil fuels. 鈥淭hey are not doing much because I think it鈥檚 completely outside their domain of expertise.鈥

Offshore Energies UK, an industry body that represents the UK鈥檚 offshore energy industry, including oil, gas, wind, carbon capture and hydrogen, declined to comment directly on the study鈥檚 findings. However, it pointed to a previous statement from its chief executive, David Whitehouse. 鈥淔ar from being in conflict, oil and gas, wind, and emerging low-carbon technologies are part of one integrated system. It is the skills of our people, the same people who built the North Sea that will deliver this transition,鈥 .
