Occasional Thoughts on Climate Change

I think you're generally reinforcing my point, which is that this thing is much harder than most people thought it would be, and we're making less progress than people thought we would even given the increase in the use of renewables that we've seen.

You say "Renewables only began to move the needle in this decade.", but there is no "this decade" in that chart - there is only "this year", which happens to be an extreme outlier w/El Nino, showing anything other than the same trend upward.   I think that's likely the main factor, and not primarily due to energy policy.   Only time will tell though, in the years ahead.    If it's truly due to energy policy then we should see a continued bending-down of the curve.

My additional assertion would be - this is also turning out to be more economically disruptive than anticipated; vis a vis the increases we've seen in electricity prices, and the resulting economic headwinds that have been experienced, in particular by countries that have had more aggressive renewable policies.

 

Nobody thought it would be easy to replace fossil fuels. Ten years ago low carbon emission scenarios depended heavily on carbon capture, nuclear and biofuels. It has proven difficult to advance those technologies. On the other hand solar, batteries and EV have advanced much faster than anticipated and it is easier to replace fossil fuels with those technologies than anticipated.

Your views on the cost of renewables are outdated. The energy cost increases we are seeing are due to fossil fuels. Supply disruptions and the inability to meet increasing demand in a timely manner being the biggest problems. Energy costs would be even higher without renewable, batteries and EV. Countries that have to import fossil fuels are trying to find a cheaper more reliable alternative. Even in Texas, where local natural gas is plentiful, met 80% of new power demand with solar last year.

There are many reasons for our energy cost increases, but the vast majority has been renewables.  There is reams of data and articles on the subject, going back to before the current supply disruptions.

Posting data from ERCOT is cherry picking.  Texas is the one state that has the best blend of geographical conditions for wind and solar.  As I say - low hanging fruit.   Now do the same PJM (largest grid) and others.   

It's kind of like when people point out how Norway is so green with their renewables - well duh; they live in a population-sparse country with tons of mountains - perfect conditions for hydro.  Most of the rest of the world doesn't have that geographical luxury.

false statement

the true drivers of increased energy and electricity costs are increasing costs to maintain and expand an aging grid, the increasing price for fossil fuels, the increase in energy demand, and a general utility regulatory structure that prioritizes investment in massive power plants that have long capital pay-back periods

and let's not forget about the abysmally expensive energy policy choices implemented by the current administration
