Assessment of Energy Use and Greenhouse Gas Emissions in the Food System: A Literature Review
نویسندگان
چکیده
Amid growing concerns about climate change and long-term petroleum reserves, the food system looms large as a major user of fossil fuels and, as a result, producer of greenhouse gases (GHG). Indeed, these twin problems may be the significant drivers that catalyze change in the food system in the 21 century. Already we are witnessing a stream of new policies aimed at reducing greenhouse gases, including a sweeping new law in California that requires a 20% reduction in greenhouse gas emissions across all sectors by 2020 and 80% by 2050.

A Comparative Study of Energy Use and Greenhouse Gas Emissions of Canola Production
In this research, the energy flow and production energy indices of canola cultivation in Trakya province of Turkey, Golestan and Mazandaran provinces of Iran were compared. Diesel fuel and chemical fertilizer inputs were the highest consumer of energy in the production of canola in these three regions. The results indicated that despite the higher energy use of machinery in Trakya province of T...
متن کاملA Review on Environmental aspects of geothermal energ
New energy technologies, along with the benefits, are associated with challenges and Difficulties. Geothermal energy as one of the renewable energies is a clean and sustainable energy source, yet its development still has some impact on the environment such as: greenhouse gas emissions, noise pollution, surface and groundwater contamination, subsidence, and seismicity. This paper provides a bri...
