A tripling of renewable energy?

The Observer and the BBC are both reporting that the IPCC today will call for a “tripling” of renewable energy to “avert climate disaster.” 

Both reports are classic examples of how badly numbers are reported. What do they mean by renewable energy? Does this include hydro-electricity and biomass? A rather necessary distinction.

When should this tripling occur by? 2030, 2050? This is not stated.

But let’s say we tripled renewable energy, including hydro, by 2030. By itself this is highly unlikely to stop carbon dioxide emissions being higher in 2030 than they are today. Renewables, including hydro, are below 10% of global primary energy consumption currently. Tripling this is fine, but remember that total primary energy consumption increased by 30% in the last decade.

In fact in the last decade coal consumption alone increased by 1319 Mtoe. This is greater than the total consumption, not the increase, from all renewables. See how tripling renewables will not achieve as much as many think? As Hans Rosling has demonstrated most people think renewables deliver far more of our energy than it does.

The IPCC report is coming online shortly, evidently. And then I can find out what they really mean by a “tripling” of renewable energy. My guess is that they mean a tripling of the percentage of total energy consumption from renewables. Or at least I hope that’s what they mean.

  1. Its interesting that none of these reports ever call for a tripling in the closure of coal plants. Its always about increasing energy supply, adding more power generators to grids. And then they wonder why carbon emissions are increasing.
