Abstract


The most extensive and effective environmentally controlled production takes place in greenhouses. New innovations and developments for greenhouse production go hand in hand with efforts for sustainability. The greenhouses must be heated to ensure high yields and high quality. However, high heating cost (20%-60%) adversely influences production. Costs Sustainability of greenhouse production can only be maintained with increase of energy efficiency. Use of renewable energy sources in place of fossil fuels is only means to increase energy efficiency. In this work, fossil fuels and geothermal energy used for heating of greenhouses are compared based on production cost and CO2 emissions to atmosphere. The results showed that greenhouse production in Aydın with geothermal energy price of 0.06 ₺/kWh will be very advantageous compared to greenhouse tomato production in Kütahya, which can only compete with that in Antalya. Carbon dioxide emission in plastic greenhouses with double layer PE plastic heat insulation in Kütahya was 199.4 kg/m2 when imported coal was used for heating. The emissions in similar type plastic greenhouses, again heated with coal, in Aydın and Antalya were 74.4 kg/m2 and 55.5 kg/m2, respectively. Greenhouses in geothermal energy rich areas will be very advantageous, based on cost of production and CO2 emission, compared to that in Antalya region if they are heated with geothermal energy.
