Agriculture can contribute to the reduction of CO2 emissions by biomass cultivation and its use for energy purposes, as well as reduction of methan emissions originated from enteric fermentation. Nowadays, direct solar energy has become a popular energy source and it is becoming the most popular power source for households around the world. The solar energy can be used to run home appliances, but in Slovakia, mainly solar collectors are used for water heating, eventually for house heating support. The aim of the paper is to point out the GHG mitigation possibilities for the Komjatice village through biogas (methane) production and its energy utilization in cooperative farm, and by taking advantage of solar collectors on family houses. Biogas produced from livestock excrements would help the farm to generate 2.3 times more electricity than the amount of total electricity consumption in 2007 and, simultaneously, the natural gas consumption could be covered by 65%. Thus the farm potential for GHG mitigation represents 270 Mg CO2. Ten percent of households equipped with solar collectors for water heating and house heating support should mitigate the GHG emission by 183.9 Mg, and as many as 51% of this amount would support the house heating (at 22.5% utilization rate). Each family house equipped with solar collectors could reduce the CO2 emission by 1.3 Mg per year. Altogether, the utilization of usable energy by biogas generated from farm own sources and utilization of solar energy by 10% of households would reduce the annual CO2 emission amount in Komjatice by 100 kg per person.
