Why Would 46 Senators (incl'g Democrats) Support Burning Trees for Electricity?

Why Would 46 Senators Support Burning Trees for Electricity When It Contributes More to Climate Change Than Coal?
Published: July 10, 2015 | Authors: Lukas Ross | Ecowatch | News Report


Fudging the math to create the illusion of progress doesn’t actually keep carbon out of the atmosphere, and while these anti-science attacks are a familiar song from deniers, our climate champions should know better than to play along.


Chopping down trees and feeding them to power plants for electricity is a genuinely awful idea. Unfortunately, none of this stopped 46 senators from publicly endorsing the idea last week. Led by Sen. Susan Collins (R-ME) and Sen. Jeff Merkley (D-OR), the group wrote a letter to the U.S. Environmental Protection Agency, U.S. Department of Agriculture and Department of Energy demanding that the agencies accept something that is clearly, demonstrably false: that biomass power is carbon neutral. While the letter was chock full of anti-science Senators like David Vitter (R-LA), others like Diane Feinstein (D-CA) and Jeanne Shaheen (D-NH) fancy themselves climate leaders and should know better.



The science is clear. Sending whole trees through the smokestacks of power plants is a terrible way to generate electricity. Even using rosy accounting assumptions, it could take at least 50 years to work-off the carbon debt and break even with coal, meaning that burning wood now puts extra emissions into the atmosphere at precisely the time when reductions are most important. At the end of the day it is simply an inefficient source of electricity, emitting 50 percent more carbon than coal generating the same amount of energy. Leaving trees alone and allowing them to function as natural carbon sinks is a much more effective way to mitigate climate change.

The troubling part is that the timing of this letter wasn’t an accident. Any day, the U.S. EPA is expected to release the final version of its Clean Power Plan, the rule designed to lower carbon emissions from power plants. It hurts biodiversity, belches toxic chemicals and contributes more to climate change than coal—all while masquerading as a source of clean “renewable” energy....

You know to worry when supposed climate champions are willing to line up with outright deniers in order to promulgate an industry myth. The letter contains loads of lawmakers who hate the EPA and want to sabotage the Clean Power Plan, including avowed climate deniers like Bill Cassidy (R-LA) and Shelley Moore Capito (R-WV). Also on the list are senators like Cory Gardner (R-CO) who sometimes admit that climate change is real, but who avidly supports doing nothing about it.

On the other side of the spectrum, these deniers have some strange company. Sen. Jeff Merkley led the charge for the democrats, and he has lifetime score from the League of Conservation Voters of 98 percent. He was joined by other high profile environmental champions like Dianne Feinstein (D-CA) and Al Franken (D-MN), who boast lifetime scores of 89 and 93 percent respectively.

Really, the only thing these lawmakers have in common is a commitment to taking money from timber. Last November the industry poured more than $1.5 million into contested senate races, and unsurprisingly Merkley and Collins both did rather well with $40,399 and $35,250 each.

The senate isn’t the only place timber has been investing....

This is just so sad. I just don't understand why our Democrats would advocate for this, even for campaign $$$. Sherrod Brown? Al Franken? WTH? I'm so disappointed. If there is a reason other than lobbyists' campaign dollars, can anyone please explain it to me?



We really need to GET $$$ OUT OF POLITICS. This is the bottom-line, root of the problem in fighting Climate Change.

They sometimes don't ever get around to digging up the science behind everything that crosses their desk, and sometimes just accept the things presented to them as being 'honest', even if we think they should know better. 'Biomass' is one of those 'eco-friendly' sounding words. After all, it's not 'fossil fuel', so it sounds a lot better until you actually do get down to the actual science.

Biomass burning: a major carbon polluter
http://www.pfpi.net/carbon-emissions

It’s often claimed that biomass is a “low carbon” or “carbon neutral” fuel, meaning that carbon emitted by biomass burning won’t contribute to climate change. But in fact, biomass burning power plants emit 150% the CO2 of coal, and 300 – 400% the CO2 of natural gas, per unit energy produced.

These facts are not controversial and are borne out by actual air permit numbers.
The air permit for the We Energies biomass facility at the Domtar paper mill in Rothschild, WI, provides an example of how biomass and fossil fuel carbon emissions compare. The mill has proposed to install a new natural gas boiler alongside a new biomass boiler, and presented carbon emission numbers for both. The relevant sections of the permit are shown below. They reveal that the biomass boiler would emit 6 times more carbon (at 3,120 lb/MWh) than the adjacent natural gas turbine (at 510 lb/MWh).


Burning biomass emits more CO2 than fossil fuels per megawatt energy generated:

1. Wood inherently emits more carbon per Btu than other fuels

Natural gas: 117.8 lb CO2/mmbtu
Bituminous coal: 205.3 lb CO2/mmbtu
Wood: 213 lb CO2/mmbtu (bone dry)

2. Wood is often wet and dirty, which degrades heating value Typical moisture content of wood is 45 – 50%, which means its btu content per pound is about half that of bone dry wood. Before “useful” energy can be derived from burning wood, some of the wood’s btu’s are required to evaporate all that water.

3. Biomass boilers operate less efficiently than fossil fuel boilers (data from air plant permit reviews and the Energy Information Administration)

Utility-scale biomass boiler: 24%
Average efficiency US coal fleet: 33%
Average gas plant: 43%

The other part of the story is that the CO2 emissions are not from CO2 sequestered within fossil fuels. The CO2 released was drawn down from atmospheric CO2 when the tree grew.

That is why it is termed "carbon neutral" - words have meanings.

Meant to sound like the opposite of what they are.

Most of the biomass energy we use today comes from unsustainable sources that are not an improvement over fossil fuels: ethanol, made by fermenting food crops like corn and sugarcane, which require large amounts of land, water and chemicals to grow; and wood or even whole trees from forests, which are often "co-fired" with coal in power plants, increasing global warming pollution and threatening our forests as well.

The OP is BS.

As for the blurb from NRDC - First, ethanol is completely different than biomass.
It is an energy storage technology that provides high density portable fuels. It is not an answer to our transportation emissions, but we will use it as an effective part of the fight against carbon in other applications such as the agricultural sector and the heavy equipment sector.

Biomass is the feedstock for ethanol, but when discussions focus around 'biomass' they are invariably about burning it to run steam generation of electricity.

And they are right when they say biomass is often not done sustainably. That doesn't not, in any way however, give validity to the OP. The issue isn't the technology itself it is the regulatory environment that is it operating under. Let me give you an example that is positive - Japan. It is the most heavily forested industrial nation on Earth. Most of those forests however, are farmed and have been for over 200 years.
Sustainable and renewable and carbon neutral because the regulatory system ensures it is managed that way.

It isn't the technology.

Even the WH says the carbon neutral of biomass myth is BS~

White House rejects biomass as carbon neutral - Policy Statement - June 23, 2015

But if you're so interested in other countries, here's what is going on in Australia~

NEW SCIENTIFIC RESEARCH has called into question the wisdom of the Australian senate's decision last week to allow the burning of wood under the renewable energy target.

The Australian forests studied absorb more carbon dioxide by being left alone than by being logged, even in a sustainable way, according to three scientists from the ANU.


Andrew Macintosh, Heather Keith and David Lindenmayer analysed climate-changing greenhouse gas emissions from the full life cycle of forests on the NSW south coast.

"The object of the paper was to draw attention to a flaw in a lot of the life cycle analyses on products and systems. What in the past that a lot of people have forgotten about is the impact of what we call policy institutions," said Associate Professor Andrew Macintosh, from the ANU College of Law.

"What we found is that for native forests in the southern part of NSW, conserving it is better for the climate than harvesting it and putting it into wood products."

He used the example of beef to explain the implications policy can have on understanding carbon dioxide emissions. If beef is considered to emit a lot of carbon dioxide then it would be bad for the environment. However if government policy said that all beef producers were required to plant trees to absorb the emissions, then beef would be — in effect — carbon neutral.

They applied the same logic to Australian forestry and found that policy can have a similar impact on whether the industry is good or bad for carbon dioxide emissions.

Andrew Macintosh explains: "If you burn biomass and you get credits under the renewable energy target, the question is: does that reduce emissions across the electricity sector as a whole? Answer: no.

"If the scheme works so that if you increase the amount of biomass that you burn and get credits, by definition it means that you're not displacing fossil fuel generation. You're actually going be displacing another renewable generator, because if that biomass was not burned, then another generator — wind, solar, one of the other types of renewable energy — would fill the void filled left by the non-burning of that biomass,"
he said.

Considering the hostile policy environment for renewables in AU under the Abbott Regime, that is exactly what you'd expect.

This isn't a debate, it is a well understood and settled issue.

For example look into the traffic in wood pellets from the US to EU to see how good intent about good technology can become subverted and produce negative outcomes.

A: The IPCC Guidelines do not automatically consider biomass used for energy as "carbon neutral," even if the biomass is thought to be produced sustainably, because:

 1) in any time period there may be CO2 emissions and removals due to the harvesting and regrowth of bioenergy crops;
 2) land use changes caused by biomass production can also result in significant GHG fluxes; and
 3) there may also be significant additional emissions which are estimated and reported in the sectors where they occur e.g.:
a. from the processing and transportation etc. of the biomass;
b. direct methane and nitrous oxide emissions from the biomass combustion;
c. from the production and use of fertilisers and liming if either is used in cultivation of the biomass.

For example, direct methane and nitrous oxide emissions from biomass combustion for energy use are reported in the energy sector.

Burning trees is mostly carbon neutral. We use local wood to heat our home for this specific reason. The carbon they release in a burn is equal to the carbon they absorbed when growing.

Existing state regulations insure that clear cutting rarely happens and states maintain the net acreage of harvestable forests. If that weren;t the case, we would have stripped the continent of trees by now.

Compared to the typical fuel such as coal, gas, and others, this solution is a definite improvement, especially when the fuel is usually byproducts of the lumber industry.

The hurt bewilderment by the OP because environment-positive lawmakers signed on is kind of immature.

The "how long did they take to burn" question is a distraction and has no bearing on the debate.

What you seem to be saying is that the time it takes a tree to grow (50 years) is the equivalent of the 65,000,000 years it took for oil to develop from old forests.

It isn't. In fact, it isn't by a factor of 0.0000008.

So let's look at this reasonably with a simple cycle. I cut down 120 trees and plant new ones to grow in their paces. I burn the wood to heat my home and the backyard yurt in which my wife and I live. The carbon emissions go into the atmosphere. As time goes on, the trees we planted absorb carbon from the atmosphere that in 25-50 years is equivalent to the carbon i released that winter years ago.

That's what you call carbon neutral.

That's the way we've been doing it in Maine for several hundred years. Woodsmen have harvested the entirety of Maine many-many times, but careful forestry insures the timber is always renewing itself.

The real question is whether the alternative (oil or some such) is worse, and the answer is that it is worse. In fact, all alternative energy has its impact on the environment just like conventional sources.

We choose wood because it is local and carbon neutral. If I were in the desert i would use solar despite the horrible impact the manufacture of the electronic components has on the environment. If I were in the plains, i would use wind, despite the epileptic seizures from strobing lights, dead birdies, electronic components, transmission lines, and the danger of flinging ice from the blades.

It's about reasonable choices that reduce the impact our passage through this world has on the environment.

Like I said, the OP is bad science.

32. Biomass has been categorized as "green power" in Europe.
Mon Jul 13, 2015, 07:33 PM
Jul 2015

In Germany, biomass is still contributing more to the electricity stream than solar, according to Frauenhofer:
https://www.energy-charts.de/

scroll down a bit, and they break it down. In the first half of 2015, biomass produced 23 TWH; PV solar 18.7 TWH, nuclear 45.8 TWH, wind 40.5 TWH. Lignite and coal accounted for 67.6 TWH and 47.9 TWH respectively.

In terms of the renewable mix, biomass has become quite important in Germany because it is a steady source, unlike wind and solar.

Yes, biomass and ethanol contribute CO2; the theory is that they are renewables and that if they are sustainably harvested, the net withdrawals of CO2 from the atmosphere make them CO2 neutral sources.

How Europe’s climate policies led to more U.S. trees being cut down


A logging truck loaded with freshly cut hardwoods enters the Enviva wood-pellet plant in Ahoskie, N.C. (Joby Warrick/The Washington Post)

.....But that claim is increasingly coming under challenge. A number of independent experts and scientific studies — including a new analysis released Tuesday — are casting doubt on a key argument used to justify the cutting of Southern forests to make fuel. In reality, these scientists say, Europe’s appetite for wood pellets could lead to more carbon pollution for decades to come, while also putting some of the East Coast’s most productive wildlife habitats at risk.

From the point of view of what’s coming out of the smokestack, wood is worse than coal,” said William H. Schlesinger, the former dean of Duke University’s Nicholas School of the Environment and Earth Sciences and one of nearly 100 scientists to sign a letter to the Environmental Protection Agency last year asking for stricter guidelines on using biomass to generate electric power. “You release a lot of carbon in a short period of time, and it takes decades to pull that carbon back out of the atmosphere.”

...Facing mandates to cut back on coal, European governments are offering generous subsidies to utility companies that switch to biomass and other renewables. The price break makes wood pellets — easily twice as expensive per ton as coal — affordable. For formerly coal-dependent countries such as Britain, wood pellets are an especially attractive option because they can be burned in the country’s existing coal-fired power plants without significant modifications.

As a result, demand for wood pellets is soaring, particularly from the United States. U.S. exports of wood pellets doubled between 2012 and 2014, from 2 million tons to 4.4 million, and climate policies are expected to drive even higher increases over the next decade. After surpassing Canada in 2012, the United States “continues to be the largest wood pellet exporter in the world,” an April report by the U.S. Energy Information Administration stated.
