According to the research of the magazine Economist from 2006, people burn on Serbian fields as much energy as two Djerdaps produce per one year. The magazine Economist looks back on the research about parts of organic waste that Ministry for the environmental protection has made as a part of the National program for energetic efficiency where it is said that our farmers burn (which is illegal) 12,5 million tons of different plant waste and leftovers. Only 1/3 of that waste, which is one million tons of plant products are energetically equal to 11 billion kilo watts per hour of electric energy, which is equal to the production of energy of two water plants in Serbia. That is all together 2800 mega watts of installed power. Those three million tons of the organic waste costs, energetically as well as financially, as much as one million tons of oil (one third of what we import), or 1,2 billion m3 of natural gas, which is even more, that is one half of what we import per year, or finally, over 5 million tons of coal, which is 15 % of our total domestic production per year.
