Here's a little perspective on renewable energy, and why fossil fuels aren't leaving anytime soon.
The big slide in renewable energy tells the real story
No, renewables are not taking over the world anytime soon. Guest essay by Bjørn Lomborg We have spent the last two centuries getting off renewables because they were mostly weak, costly and unreliable. Half a century ago, in 1966, the world got 15.6% of its energy from renewables. Today (2016) we still get less of our…

We have spent the last two centuries getting off renewables because they were mostly weak, costly and unreliable. Half a century ago, in 1966, the world got 15.6% of its energy from renewables. Today (2016) we still get less of our energy at 13.8%.
With our concern for global warming, we are ramping up the use of renewables. The mainstream reporting lets you believe that renewables are just about to power the entire world. But this is flatly wrong. . . .
Most of the renewables are not solar PV and wind. Today, almost 10 percentage points come from the world’s oldest fuel: wood. Hydropower provides another 2.5 percentage points and all other renewables provide just 1.6 percentage points, of which solar PV and wind provide 0.8 percentage points.
Neither will most renewables in 2040 come from solar PV and wind, as breathless reporting tends to make you believe. 10 percentage points will come from wood. Hydropower provides another 3 percentage points and all other renewables provide 6 percentage points, of which solar PV and wind will (very optimistically) provide 3.7 percentage points.
Oh, and to achieve this 3.7 % of energy from solar PV and wind, you and I and the rest of the world will pay – according to the IEA – a total of $3.6 trillion in subsidies from 2017-2040 to support these uncompetitive energy sources. (Of course, if they were competitive, they wouldn’t need subsidies, and then they will be most welcome.) . . .
