Biomass
energy is, perhaps, one of the more controversial types of alternative energy
that is being used today. Biomass energy
is the energy that is derived from organic matter of plants and animals.
Biomass in the form of dead plants, trees, grass, leaves, crops, manure,
garbage animals waste can be a great source of alternative fuels that can be
used to replace fossil fuels. Plants make use of process called photosynthesis
that converts energy from the sun into chemical energy. This energy gets
transferred to animals when they eat plants. When plants and animals waste are
burned, the carbon dioxide and waste stored inside them is released back into
the atmosphere.

Europe primarily at fault for biomass expansion
September
2015: Biomass accounts for roughly two
thirds of renewable energy in the European Union. Although biomass can come
from many different sources, wood is by far the most common. pdf

February 2017: Most
wood energy schemes are a ‘disaster’ for climate change. Using wood pellets
to generate low-carbon electricity is a flawed policy that is speeding up not
slowing down climate warming. That's according to a new study which says wood is not carbon
neutral and emissions from pellets are higher than coal. While much of the
discussion has focussed on wind and solar power, across Europe the biggest
source of green energy is biomass. It supplies around 65% of renewable power -
usually electricity generated from burning wood pellets. EU Governments under
pressure to meet tough carbon cutting targets, have been encouraging
electricity producers to use more of this form of energy by providing
substantial subsidies for biomass burning. Current EU regulations do not count
the emissions from the burning of wood at all, assuming that they are balanced
by the planting of new trees. link

Arguments about biomass.
While biomass is claimed to be renewable and carbon neutral, in that trees etc
can be replaced, the pollution that is created from burning the wood and other
natural materials can be as bad as the pollution that comes from
coal and other types of energy resources; it is hard to claim it is a clean or efficient
power energy. Wood is a major source of biomass energy. To produce
considerable amount of power, large amount of wood and other waste products
have to be burned. The desire to produce energy on a large scale can lead to deforestation
that would destroy the homes of large number of plants and animals. link
January
2017: E.U. loophole counts wood energy
as “carbon neutral.” It’s not. As
American foresters ramp up logging to meet
the growing demand for wood pellets by power plants on the other side
of the
Atlantic Ocean, a new European wood energy proposal would allow the
power
plants to continue claiming their operations are green for at least 13
more
years, despite releasing more heat-trapping pollution than coal. Most
of the
wood fueling converted coal plants in England, Denmark, and other
European
countries is coming from North American forests. Each month, about 1
million
tons of tree trunks and branches from southern U.S. pine plantations
and
natural forests is being turned into pellets and shipped to European
power
plants, mostly to Drax power station in the U.K. The growing
transatlantic
trade is being financed with billions of dollars in European climate
subsidies because
of a regulatory loophole that allows wood energy to count as if it’s as
clean
as solar or wind energy, when in reality it’s often worse for the
climate than
burning coal. Only the pollution released when wood pellets are
produced and
transported is counted on climate ledgers. Actual pollution from the
smokestack, by far the greatest source of carbon pollution from wood
energy, is
overlooked. link
Drax power plant in UK.
April
2017: Drax plant is England UK’s biggest emitter of CO2. In 2016 Drax
burnt pellets made from approximately 13 million tons of wood. Just over half of the wood burnt
at Drax comes from the United States, and most of this is supplied by the
pellet company Enviva. Drax opened in 1974 in Yorkshire as a coal-fired power
station, and in 2012 it began the process of converting three of its six
generators to run on biomass in the form of imported wood pellets. This
conversion is now complete, with 65% of the elctricty Drax generated in 2016
coming from biomass. While Drax describes itself as "Europe's largest
decarbonisation project", its portfolio now covers three forms
of dirty energy: coal, biomass, and, since 2016, gas. Drax
is now also the world's largest biomass power station, burning the equivalent
of more than the UK's total annual wood production each year. link
February 2018: UK pushed to water down EU biomass regulations. The British government pushed to weaken
EU controls on biomass energy even though the technology will undermine efforts
to contain global warming for up to half a century, according to research
released today. A group of high
profile climate scientists warned this would accelerate climate
change because the proposal tolerated the cutting down and burning of whole
trees, a process that releases more CO2 into the atmosphere than replanted
trees can absorb for decades, if not centuries. link
Wood pellets from the US
June 2015: The US is cutting down forests to feed Europe’s
biomass fuel craze. Since 2012, the US has
held the title of world’s number one wood pellet exporter. What’s the big deal
with wood pellets? Well, Europe has very keen on replacing coal with more
environmentally friendly wood pellets—except, well, depending on who you ask, wood
may not be that great either. Thousands of trees are being chopped down in the
U.S. each month, ground into sawdust, pressed into pellets, and shipped to
Europe. These wood pellets, which are a type of biomass fuel, can often be
burned in existing coal power plants, making them an attractive alternative to
countries trying to get off of coal. link
