For those outside of the UK, you can watch BBC Panorama: "The Green Energy Scandal Exposed" here, to see where Drax gets its bioenergy from.
Basically, industrial bioenergy is a dirty business.
Though, the "bio is worse than coal" is misleading.
1/
Yes, burning wood emits more CO₂ than burning coal. But, the entire point of burning wood is that it grows back. Unlike coal!
The question is whether the wood is sourced sustainably. Put the focus there.
2/
You can also get into semantic arguments: Did the wood grow first or was it harvested first? If you have a sustainable forestry operation, this is not really a question, as you consider the landscape under management.
3/
As BBC Panorama showed, it seems at least some of the Drax feedstock is sourced in an unsustainable way. Now, think if we had thousands of these biomass plants around the world. It ain't going to work! The scale is too big.
(scenarios assessed in IPCC disagree though)
4/
Some forms of bioenergy maybe ok. Take each solution on its merits.
You don't need to say wood is worse than coal to make a case Drax is harvesting primary forest or doing things unsustainably.
5/
For those that missed it, here is how Norway uses its bioenergy. Mainly in heating homes and some in industry, but transport fuels are imported.
"Something seen on the map may not correspond to what is in the territory; worse, something not seen on the map may be encountered when we explore the territory."

"Can we escape model-land by targeting exclusively the less comfortable, but better-informed and much more relevant real-world entities in decision-making?"

US fossil CO₂ emissions peaked around 2007, & have since declined ~20% whilst GDP has grown >20%.
Why is this?
1/
First, is the US using more energy? No.
Most economies have a decline in energy per unit GDP (E/GDP) over time, due to structural change (e.g., more services), efficiency improvements, etc. In fact, energy use has dropped slightly in the US!
This helps lower CO₂ emissions.
2/
In addition, & this is the biggest change in the US, energy use now has much lower CO₂ emissions (CO₂ per energy started to decline in 2007).
This is the shift from coal to gas & expansion of renewables.
People often say that fossil CO₂ emissions are on track to be roughly constant in the decades ahead & extrapolate this to 2100. People rightly point out this is uncertain.
What happens to temperature if:
* Emissions are constant
* Emissions grow 50%
* Emissions decline 50%
1/
CO₂-induced warming is best described by cumulative CO₂ emissions (TCRE).
What happens to CO₂-induced warming in 2100 if:
* Emissions are constant: 2.8°C
* Emissions grow 50%: 2.5°C
* Emissions decline 50%: 2.1°C
(and rising in all cases)
2/
Non-CO₂ warming is not included here, so add another ~0.3°C in 2020 & ~0.5°C in 2100. There are of course climate uncertainties.
To get higher warming levels, there really needs to be much higher emissions, or some nasty climate feedbacks.
