wind farm impact on generation adequacy in power systems
در سال های اخیر به دلیل افزایش دمای متوسط کره زمین، بشر به دنبال روش های جایگزین برای تامین توان الکتریکی مورد نیاز خود بوده و همچنین در اکثر نقاط جهان سوزاندن سوخت های فسیلی در نیروگاه های حرارتی به عنوان مهم ترین روش تولید توان الکتریکی مطرح بوده است. به دلیل توجه به مسایل زیست محیطی، استفاده از منابع انرژی تجدید پذیر در سال های اخیر شدت یافته است. نیروگاه های بادی به عنوان یک منبع تولید توان...
15 صفحه اولDairy farm cost efficiency.
A stochastic cost equation was estimated for US dairy farms using national data from the production year 2000 to determine how farmers might reduce their cost of production. Cost of producing a unit of milk was estimated into separate frontier (efficient) and inefficiency components, with both components estimated as a function of management and causation variables. Variables were entered as im...
متن کاملSustainable production of dairy farm systems
Sustainability of dairy farm production systems can be measured by the intersection between profitability and environmental stewardship. It is clear that unprofitable farms are destined to go out of business. Similarly, although not as evident, farms that are not efficient in the use of input resources, having higher wastages, and consequently producing more emissions, are likely to be un-susta...
متن کاملWhole-farm Phosphorus Management on Dairy Farms
Most dairy farms in Wisconsin continue to follow a fairly generalized formula of how to produce milk. Cows and replacement heifers are fed primarily homegrown feed from crop rotations comprising alfalfa (Medicago sativa L.), corn (Zea mays L.), oats (Avena spp.) and soybean (Glycine max L. Merr.). Protein and mineral supplements are purchased to compliment dairy diets. However, the dairy indust...
متن کاملUsing Ecophysiology to Improve Farm Efficiency: Application in Temperate Dairy Grazing Systems
Information on the physiological ecology of grass-dominant pastures has made a substantial contribution to the development of practices that optimise the amount of feed harvested by grazing animals in temperate livestock systems. However, the contribution of ecophysiology is often under-stated, and the need for further research in this field is sometimes questioned. The challenge for ecophysiol...
