The Minsky Moment

The purpose of studying economics is not to acquire a set of ready-made answers to economic questions, but to learn how to avoid being deceived by economists.

Green energy in the UK, which includes wind farms, solar, biomass, and hydro plants, generated more electricity than coal, oil, and gas in the third quarter of 2019, according to a new report by Carbon Brief.

Carbon Brief says:

During the three months of July, August, and September, renewables generated an estimated total of 29.5 terawatt hours (TWh), compared with just 29.1TWh from fossil fuels, the analysis shows.

This is the first-ever quarter where renewables outpaced fossil fuels since the UK's first public electricity generating station opened in 1882. It is another symbolic milestone in the stunning transformation of the UK's electricity system over the past decade.

Green energy in the UK has more than quadrupled since 2010, and fossil-fuel generation of electricity has halved, from 288TWh to 142TWh in the last 12-month period.

Gas is now responsible for the majority of that fossil-fuel output. The BBC reported on October 7 that four new gas-fired turbines at Drax power station near Selby in North Yorkshire were approved by the British government, despite a ruling from its own Planning Inspectorate that said more gas would contribute to climate change, despite replacing coal. Drax produces 7% of the UK's electricity.

However, Carbon Brief asserts that "it is unlikely that all of the planned new gas capacity will get built."

Further, it should be noted that biomass is not zero carbon.

As of the third quarter, the approximate breakdown of sources of UK electricity is as follows, from highest to lowest:

Gas: 38%
Wind: 20%
Nuclear: 19%
Biomass: 12%
Solar: 6%
Coal and oil: 1%
The opening of new offshore wind farms has been the main reason for this surge in UK green energy. Carbon Brief continues:

In total, government contracts for offshore wind will take capacity from nearly 8,500 MW today to around 20,000 MW by the mid-2020s. The government and industry are jointly aiming for at least 30,000 MW of offshore wind capacity by 2030, with two further contract auctions already expected.

Carbon Brief's analysis was verified against published Department of Business, Energy, and Industrial Strategy figures.

That's the low hanging fruit, next ?
Well, green energy such as solar and wind is vastly more cheaper now than it was in 2010, so if they can quadruple the amount of green energy produced over the next decade, that would push the fossil fuel plants completely out of business.

QuoteWhile the rest of the world has cut coal-based electricity over the past 18 months, China has added enough to power 31 million homes.

That's according to a study that says China is now in the process of building or reviving coal equivalent to the EU's entire generating capacity.

China is also financing around a quarter of all proposed coal plants outside its borders.

Researchers say the surge is a major threat to the Paris climate targets.

China's reliance on coal as a key step in developing the economy led to the fabled "one coal plant a week" building programme between 2006 and 2015.

But the push had many negative consequences, choking the air with pollution in many Chinese cities and leading to huge overcapacity. Many of these plants were only able to run 50% of the time.

In 2015, in an attempt to curb the growth, the national government tried to clamp down on new-build coal. However, it continued to allow provincial governments the freedom to issue permits for new coal plants. That move misfired badly.

Local authorities subsequently permitted up to five times more plants than in any comparable period.

According to Ted Nace, from coal researchers Global Energy Monitor, it was like a "snake swallowing a goat".

"This goat that the snake swallowed is still moving through the snake, and it's coming out in the form of another 20% in the Chinese coal fleet on top of a fleet that was already over-built," Mr Nace added.

The researchers say that through 2018 and up to June 2019, countries outside of China cut their coal power capacity by 8.1 gigawatts (GW). In the same period, China added 43GW, enough to power around 31 million homes.

The authors say that right now the amount of coal power under construction or under suspension and likely to be revived is about 147.7GW, an amount that is almost the same as the entire coal generating capacity of the European Union (150GW).

Compared to the rest of the world, China is building about 50% more coal plants than are under construction in all other countries combined.

The country is on track to top 1,100GW of coal by 2020.


The Chinese government has signalled that it wants to rely less on coal for the country's energy production and is making some headway cutting coal's share of total energy from 68% in 2012 to 59% in 2018.

However, despite the share going down, absolute coal consumption has gone up in line with overall energy demand.

What concerns the researchers is that within China, coal and electricity industry groups are pushing for an even bigger increase in the country's overall coal power capacity.

"The thing we are super worried about is that industry has actually organised to keep the whole thing going," said Ted Nace.

"There are three different powerful trade groups, proposing to increase the coal fleet by 40%. This is sheer madness at this point."

China is also busy financing coal development outside the country, funding over a quarter of all the coal plants outside its borders in countries like South Africa, Pakistan and Bangladesh.

Observers outside of China say they are concerned that by building or permitting these plants, the authorities are locking in a form of power generation that just doesn't make sense economically.

"The economics will not be borne out," said Mark Lewis, head of climate change investment research at BNP Paribas Asset Management.

"I would argue that almost all this new capacity that's being added will never make the economic return on which they have been premised. Those assets that are coming online now will have to be written down; they will be stranded assets essentially."

The bigger question is how this new coal will affect the ability of the world to meet the targets set out in the Paris climate agreement.

The researchers say that by 2030, China needs to reduce its coal power capacity by over 40% from current levels in order to meet the reductions required to hold global warming well below 2C.

"China's proposed coal expansion is so far out of alignment with the Paris Agreement that it would put the necessary reductions in coal power out of reach, even if every other country were to completely eliminate its coal fleet," said co-author Christine Shearer of Global Energy Monitor.

"Instead of expanding further, China needs to make significant reductions to its coal fleet over the coming decade."

Global Energy Monitor was originally known as Coal Swarm and has received funding from environmental groups, including the ClimateWorks Foundation, the Rockefeller Family fund, the US National Resources Defence Council, the European Climate Foundation, among others.

A nifty graph to better visualize Mono's point. Chinese carbon emissions.



Apparently the Chinese are opening one large coal plant a week. Greta better get on the case.

I don't know if we really need more evidence that China is the modern world's greatest threat to civilization.

How is that even possible? How can China produce six or seven times as many emissions as we do?

They've been on a massive coal plant construction spree since about 2000.
