The German newspaper Frankfurter Allgemeine Sonntagszeitung explains that with the price of grain falling and that of fuel oil rising, it is more cost - effective for a farmer to burn his wheat for heat than to sell it to buy oil. Six pounds [2.5 kg] of wheat costs him 20 cents to grow, but if burned, that quantity of wheat would produce about the same heat as a quart [1 L] of fuel oil, which costs 60 cents.
Saksa ajaleht „Frankfurter Allgemeine Sonntagszeitung ” selgitab, et kuna teravilja hind langeb ja kütteõli oma tõuseb, on põllumehel ökonoomsem oma nisu kütteainena kasutada, selle asemel et seda müüa ja siis kütteõli osta. 2,5 kilo nisu kasvatamiseks kulub 20 senti, ent kui selline kogus põletada, võrduks saadav soojushulk ühest liitrist kütteõlist saadava soojushulgaga, mis aga maksaks 60 senti.
