Biofules, biomass , wood pellets et al are a disaster if you believe more CO2 will cause Global Warming.
Does replacing coal with wood lower CO2 emissions?
Dynamic lifecycle analysis of wood bioenergy

In sum, although bioenergy from wood can lower long-run CO2 concentrations compared to
fossil fuels, its first impact is an increase in CO2, worsening global warming over the critical
period through 2100 even if the wood offsets coal, the most carbon-intensive fossil fuel.
Declaring that biofuels are carbon neutral as the EU and others have done, erroneously
assumes forest regrowth quickly and fully offsets the emissions from biofuel production and
combustion. The neutrality assumption is not valid because it ignores the transient, but
decades to centuries long, increase in CO2 caused by biofuels.
A broken analog clock is right twice a day. So I’m quoting from the Guardian again.
A few quotes:
“In the middle of the 19th century, wood burning rose to such levels that western Europe was almost completely deforested. Ironically, the rise of coal burning saved the situation”
” carbon emissions will rise by 6% or possibly more if wood is allowed to continue to provide more and more of Europe’s energy output”
“Europe has increased its use of renewable energy sources to provide it with power, and about half of that rise has come from burning biomass. Unfortunately, says Beddington, if that increase continues Europe will soon need to burn an amount of wood greater than its total harvest and would have to seek sources from other continents. Either land for farming would be turned to biomass growing or precious natural habitats will be exploited, most probably the latter”
“In generating exactly the same amount of electricity, wood will release four times as much carbon into the atmosphere as gas would do, and one and half times as much as coal. In addition, energy is used in harvesting and transport while vast stretches of land are needed to create the forests to supply generating stations with the wood they need.”
The idea that cutting down forests and burning the wood in former coal power plants is green is insane.
Another article pointing that out. Here are a few highlights.
“Ecologists say that the claims of carbon neutrality, which are accepted by the European Union and the British government, do not stand up to scrutiny. The forests of North Carolina, Louisiana, and Mississippi — as well as those in Europe — are being destroyed to sustain a European fantasy about renewable energy. And with many power plants in Europe and elsewhere starting to replace coal with wood, the question of who is right is becoming ever more important.”
“Wood burning is booming from Britain to Romania. Much of the timber is sourced locally, which is raising serious concerns among European environmentalists about whether every tree cut down for burning is truly replaced by a new one. But Drax’s giant wood-burning boilers are fueled almost entirely by 6.5 million tons of wood pellets shipped annually across the Atlantic. “
“September, some 200 scientists wrote to the EU insisting that “bioenergy [from forest biomass] is not carbon-neutral” and calling for tighter rules to protect forests and their carbon. Yet just a month later, EU ministers rubber-stamped the existing carbon accounting rules, reaffirming that the burning of wood pellets is renewable energy.”
“Wood burning is turning into a major loophole in controlling carbon emissions. The U.S. could be the next country to take advantage. A federal spending bill that passed the House of Representatives earlier this year directed the Environmental Protection Agency to establish policies “that reflect the carbon neutrality of biomass” and to “encourage private investment throughout the forest biomass supply chain,” paving the way for a boom in American pellet burning. “
“Roughly half the cut wood in the EU is now being burned to generate electricity or for heating. And there is growing evidence that the logging is damaging forests and reducing their ability to store carbon.”
I could go on. Read it and weep.
The new coal. More CO2 than coal. Yet biomass is called green by the AGW cult and the Eu and the other cult leaders .
“A controversy with reverberations across the Atlantic Ocean is brewing in Hamlet, North Carolina – a literal hamlet 120 miles northwest of Wilmington – where a new wood-pellet facility is already in the initial stages of construction.
The mill would become the fourth in North Carolina and the seventh in the Southeast built and operated by Maryland-based Enviva, the largest producer of wood pellets in the world.
The dried and compressed bits of wood produced at the plant would be shipped from Wilmington to a power company in the United Kingdom, who plans to burn them instead of coal as part of the country’s effort to slash greenhouse gas emissions 20 percent by the end of the decade.
The problem, according to many energy analysts, is that burning pellets creates more global warming pollution than coal, not less. One prominent research ecologist even calls wood biomass “the new coal.”
At the same time, environmental advocates say the new mill will further the destruction of deciduous forests in the Southeast – especially in wetlands – and disproportionately harm public health in Dobbins Heights, an overwhelmingly African-American town two miles northeast of the facility.”
“A 2015 analysis for the Southern Environmental Law Center examining the loss of forests found that Enviva wood pellets supplied to Drax would create two and a half times more greenhouse gas emissions than coal over 40 years.
A 2014 study by the U.K.’s environmental agency also factored in drying and transportation costs; it found climate pollution from southeastern U.S. wood pellets to be three times that of coal.”
DRAX would be a good name for a Bond villain. But its so much worse. They used to burn coal. Now they burn biomass.
And it is dirtier.
“emissions of particulates from the site [DRAX] were 897 tonnes last year compared to 382 tonnes in 2008.”
“The power station uses about seven million tonnes of biomass or wood pellets a year, much of it imported, particularly from the US”
“Last year, Drax received subsidies of £558 million for its biomass operation, a figure that is expected to rise to around £800 million this year as the third biomass unit comes on stream.”

And remember, burning wood chips makes more CO2 than coal.
Cash For Ash in the UK
Greenies are ash-holes.
Wealthy owners of country estates are rewarded for using excessive amounts of heat – as long as it is made using ‘green’ energy.
Some are given as much as £50,000 every year in taxpayers’ money so the UK can meet renewable energy targets agreed with the European Union.
Rewards increase as the landowners use more heat, so profits can be maximised by turning up the temperature.
The House of Schivas estate in Aberdeenshire run by Lord Catto, 66, is under investigation after the Daily Mail found it has been paid thousands in government subsidies to heat its indoor swimming pool 24 hours a day.
A reporter was told the water was kept hot at all times, even in summer.
In another case an undercover reporter was advised by a green energy salesman to raise the heat in the pool at a country manor to take advantage of the system.
The extraordinary deals mean the wealthy landowners are guaranteed to get the payments for 20 years. Almost £800million has been set aside to cover the payments this year and costs are expected to rise to more than £1billion by 2020.
Meanwhile thousands of homeowners across the country struggle to heat their homes and pay their winter bills.
