Life Cycle Assessment (LCA) is a method to evaluate the environmental impact of products and services over their entire life cycle. It’s an important tool to evaluate the environmental footprint of energy production and its storage. LCA of energy production evaluates the environmental impact of different energy sources and helps identify the most sustainable options. LCA of energy storage evaluates the environmental impact of different energy storage technologies and helps identify the most sustainable options. Results of LCA can be used to identify the most environmentally friendly options for energy production and storage, and to support decision-making in the energy sector. It’s important to also consider economic, social and technical feasibility of options when it is necessary to make a decisions.
