The renewable lobby often claims that the rising cost of fossil fuels will help make renewable energy competitive.
However, oil and gas prices remain stubbornly uncooperative. Gas prices in particular are back down to levels seen last spring, after peaking last autumn.
As is usually the way, power prices have followed the same pattern.
Oil and gas are very much cyclical markets. When supply is tight, prices rise, thus attracting more investment to increase production.
Prices therefore fall, cutting profitability and new investment, and setting the whole cycle back in motion again.
How long supply can keep meeting ever rising demand is a moot point. But there is little sign of anything changing in the foreseeable future.

German wind park protest group MenschNatur posted here explaining how even adding more wind and solar capacity does not make Germany’s energy supply any more reliable, but in fact may even make it less so.
Time and again the proponents of the Energiewende (transition to green energies) promote the idea that we must invest massively in more wind and solar power plants and that only an accelerated expansion can save the transformation to green energies.
Thus the wind energy protest group MenschNatur has taken a closer look at the increase in installed nominal capacity over the past years and compared it to what actually gets fed into the grid.
How increases in wind generator capacity affects the feed-in power is described in the following diagram. MenschNatur plotted the installed capacity of all German onshore wind turbines from 2014 to 2018, along with what actually got fed in.
