ElectricityMap – Live CO₂ emissions of electricity production and consumption

- We import electricity at an average rate of 1.2GW - mostly from Germany and Sweden - and this number keeps growing.
- Not 95% of our electricity comes from coal(as it's often assumed here), but 75% at most.
- Wholesale electricity prices in Poland are actually higher than in e.g. Germany.
- Solar reached a point where it registers in the mix - single digit percentages so far, but capacity is growing sharply.
Now of course not all of that is from burning coal for electricity (Poland had a lot of manufacturing and heavy industry), but if you were to decarbonise in general it would make a big difference to us :-)
From next year, all new homes here are required to generate most of their electricity from renewable sources, so we should start to see a big uptake in solar. I think this comes from EU regulations to decarbonise housing, so maybe there is something similar in Poland?
Unfortunately this pollution comes mostly from heating and trust me - I wish it was coal these people were burning.
To put this into perspective: last year I was celebrating new year's eve in eastern Poland and met a shopkeeper who was complaining that he can't take wood from a local national reserve.
So yeah - sorry about that. A large part of our society is focused mostly on their own convenience.
It’s still nowhere as clean as even natural gas, but even without switching fuel sources you can do a lot to make wood burn cleaner.
I wish they were. Wood was probably just a part of that gentleman's own "energy mix", consisting mostly of culm(coal dust), trash, coal and wood.
Recently coal dust for heating purposes was outlawed, along with stoves not meeting a certain standard of emissions, but that didn't stop retailers from offering products which were not up to those standards.
Anyway the main issue still appears to be awareness, as many people who could easily afford to use gas for heating still choose to pollute, because it's cheap and convenient.
Wholesale prices in Germany are anything but stable. We have often times where the price is negative and on the other hand sometimes exceeds hundreds of Euros per MWh.
Germany has allegedly 50% renewables in their electricity mix, yet they have one of the highest specific CO2 emissions per kWh in Europe, plus the highest prices.
If you want a positive example, you have to use France.
For comparison:
- France: 17 Cents per kWh, 50 grams CO2 per kWh on average
- Germany: 31 Cents per kWh, 401 grams per kWh on average
Also, the wholesale electricity price is irrelevant to the customer, especially in Germany where renewables receive a guaranteed price per kWh, _independent_ of the current wholesale price which is why our electricity bills are so high.
Germany is currently planning and building 16 gas plants and even two coal plants, so you shouldn’t take Germany as a positive example for decarbonizing the electricity sector. We aren’t.
I’m very glad Poland and the Netherlands are actually planning to build nuclear power plants.
Their "Agile Octopus" tariff has 30-minute pricing windows, estimated the previous day. Electricity is cheap in the early hours where there's a surplus, and expensive at dinner time. Idea being you can charge your EV and do your tumble-drying at the cheapest possible time. There has been negative unit pricing in the past, when generation has far exceeded demand (i.e. early hours of the morning on a windy day).
More info here: https://octopus.energy/agile/
Real time pricing sounds great, but all the supply and demand effects economists love go away when you delay pricing effects by a day... Why do that?
And wholesale prices matter to investors - recently we had a large coal project shut down because with the added cost of CO2 credits the LCoE was simply too high, so nobody was willing to finance it.
you shouldn’t take Germany as a positive example for decarbonizing the electricity sector. We aren’t.
I'm not, because the UK with its shift from coal to gas+wind and increases in energy efficiency is a much better one. And also a great example how nowadays nuclear means mostly cost and time overruns.
Meanwhile France is operating on a aging fleet of nuclear reactors(35 years old on average), which hasn't increased in capacity for 20 years now. I'm not sure what's their plan when they will be forced to phase out some of the older units.
I’m very glad Poland and the Netherlands are actually planning to build nuclear power plants.
Well it's not going to happen here because these plans were a vessel for corruption from the get go.
On the other hand solar is growing because it's cheap and with two-way metering coupled with incentives homeowners have all the incentive they need to set up their own installations.
Recently various cronies came out of the woodwork, so there's a chance we will have some weirdly expensive (even for this source) offshore farms.
But it's likely that some of our national parks will be turned into biomass for coal plants sooner - that's something currently in the works at least.
We're also super proud that the data is being used by Google to ensure that they use their data centers more when the electricity is greener and to help them in goal to make their electricity usage 24/7 carbon free in 2030 (https://www.gstatic.com/gumdrop/sustainability/247-carbon-fr...)

Does anyone have insight into this? I've never pictured Australia as a big contributor to pollution.
Edit:
Here are the per-capita emissions of a few countries for comparison. It's interactive, you can add and remove (click "+ Add country" for this as well) countries from the graph as you like: https://ourworldindata.org/grapher/per-capita-ghg-emissions?...

The production mix (energy generation by source) source URL is listed on L326.
Opening the dataset in LibreOffice Calc, filtering by Region = QLD1, filtering for Current Output > 0, and sorting by Current Output descending does seem to show that the vast bulk of production reported has fuel source descriptor 'Black Coal'.
If that's a bug in the reported data or source, hopefully the ElectricityMap team can jump in to take a look. The data initially seems legit, from searching for some of the power stations listed.
Edit / addendum: worth searching for Australia in the project's GitHub issues too; there's some existing (although not directly related) investigation & validation work ongoing for that module
Queensland generates a ton of solar
Victoria uses brown coal which is basically damp coal, its incredibly inefficient compared to black coal used by NSW/Qld
Tasmania is basically 100% renewable...
If someone is running a grid-tied solar system, outbound energy might be accounted for in these statistics, but it won't show any immediate consumption of that solar generation by the property, nor will it show any battery storage, it's only capable of showing what goes through the energy meter.
https://pv-magazine-usa.com/2019/04/15/californias-solar-pow...
So we'd need electric utility companies to share the live data of how many kwh of solar and wind people are selling back to the grid in order to get an accurate regional comparison of real-time carbon intensity?
FWIU, they're already parsing the EIA data; but it's significantly more delayed than the max 2 hour delay specified by ElectricityMap.
Here's the parser for the current data from EIA: https://github.com/tmrowco/electricitymap-contrib/blob/maste...
Should the EIA (1) source, aggregate, cache, and make more real-time data available; and (2) create a new data item for behind the meter kwh from e.g. residential wind and solar?
(Edit) "Does EIA publish data on peak or hourly electricity generation, demand, and prices?" https://www.eia.gov/tools/faqs/faq.php?id=100&t=3
> Hourly Electric Grid Monitor is a redesigned and enhanced version of the U.S. Electric System Operating Data tool. It incorporates two new data elements: hourly electricity generation by types of energy/fuel source and hourly sub-regional demand for certain balancing authorities in the Lower 48 states.
> [...]
> EIA does not publish hourly electricity price data, but it does publish wholesale electricity market information including daily volumes, high and low prices, and weighted-average prices on a biweekly basis.
AFAIU, retail intraday rates aren't yet really a thing in the US; but some countries in Europe do have intraday rates (which create incentives for the grid scale energy storage necessary for wide-scale rollout of renewables).
(Edit) "Introduction to the World of Electricity Trading" https://www.investopedia.com/articles/investing/042115/under... :
> Energy prices are influenced by a variety of factors that affect the supply and demand equilibrium. On the demand side, commonly referred to as a load, the main factors are economic activity, weather, and general efficiency of consumption. On the supply side, commonly referred to as generation, fuel prices and availability, construction costs and the fixed costs are the main drivers of the price of energy. There's a number of physical factors between supply and demand that affect the actual clearing price of electricity. Most of these factors are related to the transmission grid, the network of high voltage power lines and substations that ensure the safe and reliable transport of electricity from its generation to its consumption.
Which customers (e.g. data centers, mining firms) would take advantage of retail intraday rates?
How does cost and availability of storage affect the equilibrium price of electricity?
Not just selling back. Producing - and then either using or selling.
You actually need production numbers for what's used "behind the meter" which by its nature is not directly available live or otherwise and has to be estimated.
>Which customers (e.g. data centers, mining firms) would take advantage of retail intraday rates?
Loads! In the UK you can get half-hourly priced electricity even at a domestic level (with a smart meter) and if you have loads that can be be re-scheduled (mainly EV charging but if you had an electric storage heater that would work as ell) you can save quite a lot of money.
Heavy industrial users definitely move usage around both to avoid expensive wholesale charges but also to reduce their transmission connection charges which (in the UK) are based on their usage during the most congested periods of the year. Water companies will vary pump operations for this reason and water pumping and treatment alone is 2% of electricity use.
Data centers definitely pay on a half-hourly settled basis but tend not to shift their workloads around to take advantage, some data centers will run their cooling systems in such a way as to reduce usage during the most expensive few half hours though. I have heard that larger users like Amazon, FB, Google, will automatically load balance between global centers to reduce electricity bills and carbon footprint.

That said, Australian is a large contributor to pollution. The majority of electricity is still produced from coal. It is improving, but with a federal target of only 20% renewables, a lot of financial incentive to build new generation could be about to dry up.
The map is based on figures which (correctly) assume everything creates at least some CO2 emissions over its lifetime. For example Britain's offshore wind farms are scored as 11g/kWh. Sweden's nuclear reactors, 12g/kWh. In some sense a wind turbine or a nuclear fission plant do not actually "emit" CO2 in operation, they aren't burning carbon - but you need a bunch of concrete construction and mining to have these generators, and it's at a scale where we mustn't forget it. Another reason for showing a number is that if you don't, some pro-fossil fuel person is going to say "Ah, but what about..." and so it's all baked in, same way you can find numbers for "carbon emissions" from ground source electric heat pumps. Unlike a gas boiler to heat things obviously the electric heat pump does not in fact "emit" carbon directly, but nevertheless for comparison we can estimate what the overall emissions are for one versus the other (mostly to show that yup, heat pumps are a good idea).
But notice that this is proportional. Queensland is a pretty big place, but it's only making about 4-5GW of electricity. Whereas a power district in the US might have 20+GW of coal power stations, so even if it's also got 10GW of wind or nuclear or whatever, that's many times more actual pollution.
Warming doesn't care how efficient we are, the totals matter. So in that sense getting from 5GW of coal in Queensland to 1GW of coal in Queensland (an 80% reduction) would make less difference than MISO in America going from 25GW to 20GW (just 20% reduction).
Also the market operator has their own data for CO2 intensity https://aemo.com.au/en/energy-systems/electricity/national-e... . General comment - Victoria tends to have the worst electricity supply in Australia in terms of CO2 per kWh (brown coal vs black coal elsewhere)
France: Nuclear
Norway: Hydro
Sweden: Hydro + Nuclear
That’s why nuclear in making a comeback in the mind of those who care about climate change.
Wind/Solar/Gas, with low emissions intensity and (as of September 2020) the lowest power prices in Australia.
Gas is absolutely not “low emissions”. It’s actually the second worst offender after coal (400gCO2eq/kWh vs 1000 for coal).
Where are you getting this? It's true the emissions mix is bad at night, but the absolute amount is what counts. Having a bad emission mix when no energy is being used isn't particularly concerning.
> 400gCO2eq/kWh vs 1000 for coal
That's pre-2014 numbers. Modern gas is better, around 300 gCO2eq/kWh[1].
It's not as good as solar/wind, but the fast startup time means its usage can be minimized and the low cost ($20M for a generator!) means money can be invested in truly environmently friendly sources like wind and solar instead of the money pit of nuclear power.
[1] https://www.winnipeg.ca/finance/findata/matmgt/documents/201...
During the demand peak, it was 301g.
Speaks for itself.
About the money pit, Germany spent 500 billion euros on wind and solar. And what does it have to show for it? Right now it’s 10x the CO2/kWh of France at twice the price.
If you look closely Germany has 30GW of gas capacity and it's not using it even though it would lower emissions by 50%.

This reflects my own experiences, eg questioning frequent air travel no longer gets you barrages of downvotes.
A few years ago it maybe was not clear that people had a legitimate interest in renewables. The producing companies probably do not care about the environment outside of laws, but if the request for renewables is high enough, a market can emerge and prosper.
This is very hard to predict even for smart economy people unlike me.

I sent a few tweets and emails about the data in this region but nothing happened here either
Gas (39%, 490gCO2eq/kWhr), nuclear (36%, 12gCO2/kWhr), coal (16%, 820gCO2eq/hr), wind (6%, 11gCO2eq/hr). So that's ~327. So despite coal being 16% of the energy production, it is 40% of the emissions and gas is 58% of the emissions.
Looking at NYISO we see a different story. Currently there is a lot grayed out in the gas area. Right now gas is 28% of the total electricity generation while peak of the day it is 39%.
If you look at CISO (California) you'll see the opposite happen. Mid day solar takes over and emissions drop. The famous Duck Curve. They go from 150gCO2eq/kWhr in the morning to more than double that at night. You'll also see wind die down at times. Interesting thing is how hydro changes.
So a lot comes down to how you're providing your base load and what energy sources you are using at what times in the day. If you look around the map a lot you'll see that a lot of countries/areas that have very consistent loads (and hence emissions) export a lot of their energy at those different times. While a lot of people like looking at averages the problem here is substantially complex because there's temporal components (hourly, weekly, seasonly) as well as a lot of environmental factors.
Case in point: look at France vs Germany (who has now spent 500 billion euros in renewables).
Now imagine if that money had been spent elsewhere...
I wonder how accurate and reliable the data is but if it's coming from a central European commission I expect it to be audited and verified.

It's a bit like food where our wheat crop is down 40% this year but we aren't expecting riots because the rest of the world is up.
Countries with higher voltage distribution systems (there are a few 1 megavolt in China for example) have less losses, but you still don't want to be moving much power across entire continents.
Also, I know nothing about the state of interconnects between France and the Netherlands. HVDC under the quite narrow English channel might well be the most efficient route.
I also specifically remember 9 years ago during my aforementioned undergraduate report obtaining spreadsheets from the UK National Grid with time segments containing the direction and amount of power transferring via each interconnect (you're going to have to take my word for it... my copy of that data is long gone). These also showed exactly what I described, power being imported and exported simultaneously.
I expect there is a reason for this, perhaps arbitrage but maybe more likely some minimum power has to flow to keep connected sensors/relays/whatever from misbehaving, or some other engineering reason.
I know the live data is there but it doesn’t affect the colour assessment one little bit.
Also since when is black bad? Bit racist no?

Solar capacity is listed at 52GW. Wind total capacity is 61 GW, with an mediocre 15% output.
That’s not a lot to show for 500 billion euros...
They just started up their first reactor using a domestic design, the IPHWR-700:

Compare it to http://nemlog.com.au/gen/co2e/ for example.
With Australia's commitment to the Paris Agreement and rapidly dropping prices of wind & solar generation (LCOE now less than coal derived electricity generation [0]), I hope this will change very soon! Also worth noting that China, where Australia sends a lot of coal, has committed to becoming carbon neutral before 2060 [1].

Just the theoretical idea that if you would "nuke" the black countries off the map then evertything is green and fine? Not really. Imo it should be rather based on percentage of total emissions of the world. Then map would show where difference needs to be made.
