Does a Christmas tree contain energy?

 

Answer

Weihnachtsbaum_EnergieEach year, around 30 million Christmas trees are sold in Germany. These trees not only create a cosy and festive atmosphere; after their time is over they also provide homes with warmth and electricity. This is because a large proportion of the trees go on to be chopped up into wood chips, which are then taken to biomass boilers or biomass power plants together with other leftover wood from forests, gardens and parks to be transformed into electricity or heat. If all 30 million Christmas trees were recycled in this way, they could generate enough energy to provide 60,000 households with electricity for a whole year.
