Residents of the United States who live near particle factories complain about the smoke they emit, and experts say burning wood is a "disaster" for climate change.
In Europe, this is a sensible way to realize the goal of renewable energy, but in far away to persuade Lisa ˙ Sanchez (Lisa Sanchez), let her think burning wood chips is a form of clean energy, not so easy.
At the end of her garden lies a large German granule factory in Piney Woods, in eastern Texas, which has greatly reduced the rural appeal of her hometown.The German factory produces 578,000 tonnes of wood particles a year that travel across the Atlantic to meet the booming local market.
In 2014, sanchez moved to woodville, 100 miles northeast of Houston.
"The factory was quiet, quieter than I thought," she said.But less than a year later, I began to have respiratory problems and was ill all the time.Now I have asthma and I need an emergency inhaler.
She was afraid to open the doors and Windows because she felt the air covered with dust.
The burning of wood-based forest biomass has been promoted as a cleaner, more promising alternative to coal and gas.American company has been formed, such as the Enviva thriving timber export industry, from the beginning of 2000 almost zero exports, exports of 2015 tons in 2015 to almost all products are shipped to Europe, to replace the local coal to produce electricity.
Wood grain industry claims that its use of branches and waste wood, but the environmental group, said the strong evidence that, in states such as north Carolina and Florida, a large number of valuable, undeveloped forests have been cut down, to meet the development of wood grain industry.
Last year, British researchers found that burning wood was a "disaster" to stop climate change, because old trees emit a lot of carbon when they burn, and planting trees doesn't help.Even if trees are replanted, it will take up to 100 years to grow a forest that can absorb previous carbon emissions.The fuel needed to transport wood pellets to Europe is also an important source of emissions.
As the epa advisory council, biological geochemist ˙ William Schlesinger (William Schlesinger) said: "in theory, this looks nice, but in fact, in many cases this is not feasible."
"When you cut down existing trees and burn them, carbon dioxide is released into the air immediately.No company can guarantee that they can replant trees to fully absorb the carbon dioxide.The whole renewable forest is a hoax to slow climate change.
Schlesinger added, however, if the management and certification is proper, carbon emissions will be lower than the coal burning wood, and with the expanding solar and wind energy development, burning wood can be used as a "bridge fuel".
Burning wood for energy is "misleading", climate experts say
Using biomass instead of fossil fuels may not stop global warming, experts say.
Britain's chief climate experts ˙ John Beddington says professor John Beddington, by burning biomass to prevent climate change policy with serious defects, these defects may affect efforts to curb global warming in the future.He warned that cutting down and burning trees to replace fossil fuels could have dangerous effects.
On the supply side, Europe has increased its use of renewable energy over the past decade, with about half of that growth coming from biomass burning.Unfortunately, Mr Beddington says, if this growth continues, Europe will soon run out of burning wood and must look elsewhere for resources.The latter is more likely to be cultivated on cultivated land or in natural habitats.
"Using biomass energy instead of fossil fuels seems like a good idea both nationally and globally.But these policies are not well thought out and run the risk of making things worse.Even if further emissions of carbon dioxide are prevented, biomass energy can have a huge impact on land use, both on cultivated land and in natural habitats.
In the middle of the 19th century, wood burning grew so rapidly that there was almost no woodland in Western Europe.Ironically, the rise of coal burning has saved the day.The researchers say coal is now being phased out, but it should not be an excuse to burn trees on a large scale.Instead, we should focus on solar and wind projects and other harmless and renewable sources of energy.
