The production of beer is an energy‐intensive process, and due to the progressive global increase in its consumption, this has raised environmental concerns especially regarding energy‐related impacts. The study presented herein applied the life cycle assessment methodology to quantify the greenhouse gas emissions associated with traditional supply of electricity (electric grid) and heat (liquefied petroleum gas) to a craft microbrewery. It was then considered that electricity could be provided by solar photovoltaic (PV) panels, and heat by solar collectors, and these values were compared with traditional energy supply. Solar PV electricity resulted in 66% less emissions per kWh_e consumed, and solar collectors yielded 95% less emissions per kWh_th. It was verified that there is potential for climate change mitigation associated with energy transition in breweries, considering electricity and thermal energy.

温室气体占啤酒厂能源转换的原因

啤酒的生产是耗能的过程，并且由于全球啤酒消费量的不断增加，这引起了环境方面的关注，特别是在能源相关影响方面。本文介绍的研究应用了生命周期评估方法，以量化与向手工艺酿酒厂进行的传统电力供应（电网）和热量（液化石油气）相关的温室气体排放量。当时人们认为，太阳能光伏板可以提供电力，太阳能集热器可以提供热量，并将这些值与传统能源供应进行了比较。太阳能光伏发电导致66％以下的每千瓦时排放_ë消耗，并且太阳能收集器产生95％少排放每千瓦时_第。事实证明，考虑到电力和热能，啤酒厂的能源转移有可能缓解气候变化。
