BEHIND THE SCIENCE: Renewable Energy (National Geographic)



the economy relies heavily on fossil fuels our machines in industry are powered by oil coal and natural gas but these fuels are rapidly being depleted according to the most extreme calculations in about half a century these natural resources will be exhausted in addition nature suffers from the pollution they caused to save our world we must urgently transfer to other more environmentally friendly sources of energy scientists at the University of Antwerp are studying biological energy from trees can this provide an alternative to fossil fuels in the stretch scenery of the east of Flanders lies the Benelux is biggest bioenergy plantation in 2010 researchers from the University of Antwerp planted thousands of trees here professor Reinhard Coleman's needs a research project

a negative impact up at milieu fossil fuels make a significant contribution to the greenhouse effect accelerating the rise in the earth's temperature and this could have a disastrous impact on our nature we need to find alternative environmentally friendly sources of energy natural forms of energy such as wind power and solar power are well-known but the scientists of the plantation in LA christy studies something else energy from trees professor Kellerman's and his team are conducting a lifecycle analysis of this plantation they are the only ones in the world who are carrying out such a comprehensive analysis in Lovisa colonies began Karanga ketotic Psicosis fan beat autograph cannabis fun bad planter and the stick to the politics even energy all the inner hades of processing all the manure impact an awakening pleasure that you build bear transport the favela king and the only from the plantation the researchers use scientific instruments and techniques to see how much energy the wood produces and how these trees affect the environment trees are the green lungs of our planet without them humans and animals would not be able to survive to be able to grow trees absorb carbon dioxide from the air through their leaves through their roots they draw water from the ground the chloroplasts in the leaves enable photosynthesis a process in which sunlight turns the absorbed carbon dioxide and water into nutrition for the tree such as glucose and other kinds of sugar as a result clean oxygen is released a part of these sugars are burned by the tree and carbon dioxide is emitted as a waste product since at night there is no sunlight there is also no photosynthesis so only carbon dioxide is emitted however because the absorption of carbon dioxide is higher than the emission trees can counteract global warming pollutants that humans produce with their exhaust fumes and soot from cars and machines are absorbed by trees with their leaves branches and roots they cleanse our world but trees are having to process more and more the result is devastating the greenhouse effect is intensifying and temperatures are rising too quickly this is disrupting landscapes all over the world so we need the help of trees more than ever the plantation consists of over 100,000 trees over an area the size of about 36 soccer fields voluntary persistent poop reading the villager nogouda

to measure the extent to which trees can counteract the greenhouse effect in flanders there are two of these towers one on the plantation and one in a pine forest in brass cart this forest is over eight times the size of the plantation with over 50,000 pine trees cited by the metal of Ambra Scots and the Metheny you start whistling kombuchas costitutional basta to use it and the atmosphere both

there are measuring towers spread throughout Europe in different types of landscape because every landscape has its own vegetation and every species of plant absorbs a certain amount of carbon dioxide the data from all these measurement hours is sent to several locations one of these locations is the University of Antwerp here cuma alder made heaves envisioned amid Doren spinner there is without faii precarious balance or the website your plants and hakuna download Vedas epicenter the National in Europe is over hidden boredom he bragged America today may take a decision on Clemont the equipment the researchers use for their measurements is on top of the towers these devices measure all the emitted carbon dioxide on the plantation even that of humans who just like trees breathe in oxygen and breathe out carbon dioxide the meeting is at floor not metal sensor gavel sensors Zhukova without batteries here to include a group of bazookas of mints but an immediate universe Stella after the break we'll find out if trees can be a worthy substitute for fossil fuels we'll be right back on National Geographic our dependence on fossil fuels has become a global problem the processing of fossil fuels adds to the greenhouse effect causing a rise in global temperature this change in temperature is so drastic it could disrupt the natural world in addition fossil fuels are rapidly being depleted the need for new sources of energy is greater than ever scientists at the University of Antwerp are trying to see if trees can provide a solution professor Kellerman's and his team are using these measurement towers to investigate where the trees could counteract the greenhouse effect on the seal to be open Amador did Buster maitika bracket way to cellar an unable method and in Castle al-assad the gas analyzer measures the amount of carbon dioxide that is present in the air the anemometer measures the direction of the wind as well as the wind speed both of which influence

wind beneath a portacaval an official – sadita way that is the net o open oven seal trade or did boss in order to measure the amount of wind above the trees the measurement tower has to be higher than the trees therefore the towering brass card is as much as 40 meters high that's about the same height as a 13 story apartment building the trees on the plantation in lo Christie can become as high as seven meters and they grow very quickly that's why this plantation has an adjustable tower that grows with these trees after the measurements the data goes directly to the cabins nearby here the data is transformed into graphs in brass cart the emissions have been mapped for no less than 16 years is it reversal on declare of Ambala keys the room apologies that is the open arm of and constantly

Western Europe just as in the measurement towers a gas analyzer is used to check how much carbon dioxide the plants absorb all data is gathered in the data logger which then sends it to a computer to
