Fascinating day in Abu Dhabi yesterday, where some of the biggest names in politics – not to mention the world’s media and several hundred exhibitors from around the world - have gathered for the fourth annual World Future Energy Summit.

It’s perhaps the biggest event you’ve never heard of (I certainly hadn’t before this year) where everyone from multinational oil companies to UN secretary general Ban Ki-Moon get together to discuss renewable energy and its implementation in different sectors, include motoring.

This morning’s opening ceremony was predictably packed with crowd-pleasing soundbites; Ki-Moon said the energy sector “must look beyond fossil fuels” and “we need a global clean energy revolution that makes it affordable for all”.

But there were some facts and figures dropped in that highlighted the need for the politicians, delegates and energy companies to stop the talking and start to deliver on infrastructures to support future powertrain technology manufacturers have already developed before the oil wells finally run dry.
