“…Due to great differences exist among provinces, the development of management practices is unbalanced and inadequate, which is incompatible with the rapid amplification of farm scale. With dry land and little precipitation, more energy is required to fulfill water supply in AR [44]. Alternatively, farms in HR take on more pressure of cooling and ventilation in cowsheds, resulting in high energy consumption and CI.…”

The mechanical and electrical development in dairy farming in China increases energy-related carbon emission (CE). To support the sustainable planning strategy of the department, this study calculated the CE and the carbon emission intensity (CI) of the direct energy consumed in dairy farms from 21 provinces in China. Through four dimensions analysis including the national level, farm scale, inter-provincial distribution, and main producing area, this study illustrates the impact of the environment, production, and management on CE. The total CE of nationwide dairy farming was about 2.4 Tg CO2 eq. in 2019, and the CIs of the 21 provinces varied from 0.009 to 0.216 kg CO2 eq. per kg of milk. The results indicate that the management mode applied in large-scale dairy farms (500 heads and above) varies considerably due to inadequate adaptation to climate. In general, semi-arid and semi-humid regions are more suitable for dairy farming than arid and humid regions. In the main milk-producing area, the spatial aggregation effect is visible in the carbon reduction potential. The present study suggests that further steps to promote sustainability and milk productivity are embodied when the replacement of fossil fuels and the management standardization are adapted to regional characteristics.

“…In the research study, a new term "poultry demand-side management" was suggested to increase the penetration of solar energies in poultry electricity consumption and decrease dependency on the main grid [150]. In New Zealand, dairy farms were studied to shift the main electricity consumption out of peak hours and to provide balance for the power systems [151]. Based on the results, the power consumption of the irrigation and milking-related processes contribute to the peak demand of the farm.…”

In recent years, environmental concerns about climate change and global warming have encouraged countries to increase investment in renewable energies. As the penetration of renewable power goes up, the intermittency of the power system increases. To counterbalance the power fluctuations, demand-side flexibility is a workable solution. This paper reviews the flexibility potentials of demand sectors, including residential, industrial, commercial, and agricultural, to facilitate the integration of renewables into power systems. In the residential sector, home energy management systems and heat pumps exhibit great flexibility potential. The former can unlock the flexibility of household devices, e.g., wet appliances and lighting systems. The latter integrates the joint heat–power flexibility of heating systems into power grids. In the industrial sector, heavy industries, e.g., cement manufacturing plants, metal smelting, and oil refinery plants, are surveyed. It is discussed how energy-intensive plants can provide flexibility for energy systems. In the commercial sector, supermarket refrigerators, hotels/restaurants, and commercial parking lots of electric vehicles are pointed out. Large-scale parking lots of electric vehicles can be considered as great electrical storage not only to provide flexibility for the upstream network but also to supply the local commercial sector, e.g., shopping stores. In the agricultural sector, irrigation pumps, on-farm solar sites, and variable-frequency-drive water pumps are shown as flexible demands. The flexibility potentials of livestock farms are also surveyed.

“…For this very reason, reducing the energy intensity of agriculture currently represents a major topic, as agricultural production is one of the major CO 2 producers. Activities that significantly contribute to large electricity consumption include farmland irrigation, as well as milking (Dew et al, 2021). Questions related to the price and availability of energy, or relevant commodities and goods -whether natural gas, petroleum, or petroleum products -are currently even more topical, which is especially true for the context of the entire Central European region.…”

The paper presented is aimed at the determination of electricity consumption at selected dairy farms during milking employing automatic milking systems (AMS). The research was focused on the determination of electricity consumption during the performance of essential activities that are related to the AMS utilization, i.e., electricity consumption by a single AMS unit per day, by a single assembly compressor per day, by a single AMS unit and a single assembly compressor per day, per milking, and per 1 litre of milk. Measurements were conducted at eight dairy farms in Central Europe that house dairy cows of the black-spotted Holstein cattle breed. The cattle groups assessed comprised 95 to 105 animals subjected to milking over the entire observed period. On the basis of the measurements conducted, it was observed that the average amount of energy consumed per 1 litre of milked milk was 0.0232 kWh over the entire observed period. Regarding the essential activities, the results obtained indicate that the energy consumption throughout the year is relatively balanced, despite the fact that it is affected by a wide range of factors, including chiefly the herd management, as well as overall organization of entire farm, milk yield, health status of cattle, current climatic conditions, fodder quality, etc.
