A mezÅ‘gazdasÃ¡gi Ã©pÃ¼letek Ã©s hÃ¡ztartÃ¡sok energiakÃ¶ltsÃ©gÃ©nek csÃ¶kkentÃ©se fontos a versenykÃ©pessÃ©gben Ã©s a megÃ©lhetÃ©sben
A globÃ¡lis hÅ‘mÃ©rsÃ©klet-nÃ¶vekedÃ©s kÃ¶rnyezeti vÃ¡ltozÃ¡sokhoz, a tengerszint emelkedÃ©sÃ©hez, a csapadÃ©k mennyisÃ©gÃ©nek Ã©s tÃ©rbeli eloszlÃ¡sÃ¡nak megvÃ¡ltozÃ¡sÃ¡hoz, szÃ©lsÅ‘sÃ©ges idÅ‘jÃ¡rÃ¡si viszonyokhoz vezet. Ã llat- Ã©s nÃ¶vÃ©nyfajok kipusztulÃ¡sÃ¡nak sebessÃ©ge jelentÅ‘sen nÅ‘. Bizonyos betegsÃ©gek kÃ¶nnyebben elterjedhetnek. E felÂ¬sorolt hatÃ¡sokbÃ³l lÃ¡thatÃ³, hogy a mezÅ‘gazdasÃ¡got kÃ¶zvetlenÃ¼l Ã©rinti a klÃmavÃ¡ltozÃ¡s. Fontos tehÃ¡t, hogy a mezÅ‘gazdasÃ¡gi Ã¼zemek maguk is tegyenek a kÃ¡ros hatÃ¡sok enyhÃtÃ©sÃ©Ã©rt. LehetsÃ©ges megoldÃ¡s a biomassza tÃ¼zelÃ©se, amely a mezÅ‘gazdasÃ¡gi rendeltetÃ©sÅ± Ã©pÃ¼letek Ã©s hÃ¡ztartÃ¡sok energiakÃ¶ltsÃ©geit jelentÅ‘sen mÃ©rsÃ©kli. TanulmÃ¡nyunk olyan megoldÃ¡st dolgoz ki, melyben a hÅ‘ elÅ‘Ã¡llÃtÃ¡sÃ¡hoz szÃ¼ksÃ©ges energia kÃ¶ltsÃ©ge teljes mÃ©rtÃ©kben megszÅ±nik, ami energiaerdÅ‘ telepÃtÃ©sÃ©vel lehetsÃ©ges. A kitermelt erdÅ‘ egy rÃ©sze a hÃ¡ztartÃ¡sokban hasznÃ¡lhatÃ³ fel, mÃ¡sik rÃ©sze a piacon Ã©rtÃ©kesÃthetÅ‘, melynek nyeresÃ©ge tovÃ¡bbi energiatakarÃ©kos beruhÃ¡zÃ¡sokra hasznÃ¡lhatÃ³ fel. A faalapÃº tÃ¼zelÅ‘anyag a fosszilis tÃ¼zelÅ‘anyaggal szembeni kÃ¶rnyezetkÃmÃ©lÃ©se, szÃ¡mos pozitÃv hatÃ¡sa mellett jelentÅ‘sen hozzÃ¡jÃ¡rul a kÃ¼lfÃ¶ldi orszÃ¡goktÃ³l valÃ³ energiafÃ¼gÂ¬gÅ‘sÃ©g problÃ©mÃ¡jÃ¡nak megoldÃ¡sÃ¡hoz. ------------------------------------ Global warming leads to environmental changes, rising of sea levels, changes in the quantity and spatial distribution of precipitation and to extreme weather conditions. The extinction of animals and plant species increases significantly. Certain diseases spread easily. This list indicates that agriculture is directly affected by global warming. It is important that agricultural enterprises should themselves be prepared to moderate the harmful effects. A possible approach is the use of biomass for heating that would significantly reduce energy costs of agricultural buildings and households. Our study concerns an approach of heat production that would entirely eliminate energy costs by the plantation and use of energy forests. Part of the woods from such a forest could be burnt in households and the rest could be sold in the market. Profits from the sales could be used for further energy saving investments. Wood based fuels as opposed to fossil fuels are in many respects environment friendly and they enable the country to become significantly independent of foreign energy imports.
