 'From graft to bottle'--Analysis of energy use in viticulture and wine production and the potential for solar renewable technologiesM. Smyth and J. Russell Renewable and Sustainable Energy Reviews, 2009, vol. 13, issue 8, 1985-1993 Abstract: The practice of viticulture and winemaking is highly dependent upon the weather and climate. Any future changes in the seasons, their duration, local maximum, minimum and mean temperatures, frost occurrence and heat accumulation could have a major impact on the winegrowing areas of the world. Given that the winegrowing industry has substantial energy requirements and is directly influenced by any changes in climate, the industry should be at the forefront in promoting the case of energy efficiency and the adoption of renewable technologies. Solar renewables in the form of solar thermal and photovoltaics (PVs) offer a complimentary solution to many winegrowing processes. This paper examines the limited number of world wineries that have adopted solar renewables and presents a viable case for their wide scale integration into the industry. The paper presents a range of viticultural and winemaking processes where solar energy can be directly or indirectly applied and suggests the potential for solar energy in making substantial savings in both energy use and greenhouse gas emissions. In 2005, almost 8 million hectares were under vines producing 40.2 million tonnes of grapes for crushing. The total global energy use within the winemaking industry is estimated at over 105Â PJ emitting nearly 16 million tonnes of CO2. If ancillary industries, such as bottle making and transportation are included, the total carbon footprint of the industry is estimated at over 76 million tonnes of CO2. This paper calculates that if the commercial winemaking establishments in the 'developed' wine producing regions of the world integrated a 'small' solar installation into their wineries, the potential savings are 18.3% or 19.24Â PJ of the energy used in the global winemaking industry.
