The global energy system is changing quickly as it moves toward renewable sources. This shift is marked by a large increase in the use of battery storage systems in both homes and on a larger grid scale.

全球能源系統正迅速向可再生能源轉型。這次轉型的特徵在於家庭與大規模電網中電池儲能系統的使用量大幅增加。

The Australian Energy Market Operator (AEMO) emphasizes that the use of local energy resources is changing how the national power grid is developed. Because more than 600,000 households now have batteries, the need for new power lines has decreased by about 1,500 kilometers. AEMO reports that storage capacity is growing rapidly, rising from 3 gigawatts in 2022 to an expected 45 gigawatts by 2026. This trend is happening worldwide; for example, the International Energy Agency states that battery storage is the fastest-growing power technology in countries like Germany, the US, and the UK. Furthermore, cheaper plug-in batteries are expected to make storage more accessible for renters by lowering the initial cost.

澳洲能源市場營運商 (AEMO) 強調，本地能源資源的使用正改變國家電網的發展方式。由於目前有超過 60 萬戶家庭使用電池，對新電線的需求減少了約 1,500 公里。AEMO 報告指出儲能容量增長迅速，從 2022 年的 3 吉瓦 (GW) 預計將增加至 2026 年的 45 吉瓦。這一趨勢正席捲全球；例如國際能源總署指出，在德國、美國與英國等國家，電池儲能是增長最快的電力技術。此外，更便宜的插電式電池預計將降低初始成本，使租屋者更容易使用儲能設備。

However, some problems still exist. AEMO noted that there is not enough wind energy being developed because the approval process takes too long. Additionally, the demand for electricity is changing. While home energy use may drop as people become more self-sufficient, industrial demand from data centers is expected to grow by 25% every year. From an environmental perspective, batteries help reduce emissions during peak times. Nevertheless, researchers from the University of Exeter warn that the pollution caused by manufacturing lithium-ion batteries and the lack of recycling systems may reduce some of these environmental benefits.

然而，仍存在一些問題。AEMO 指出，由於審批過程過久，風能開發不足。此外，電力需求也在改變。雖然隨著人們更加自給自足，家庭能源使用量可能會下降，但數據中心的工業需求預計每年將增長 25%。從環境角度來看，電池有助於在用電高峰期減少排放。儘管如此，艾塞克斯大學的研究人員警告，製造鋰離子電池所造成的污染以及缺乏回收系統，可能會抵消部分環境效益。

The move toward a carbon-free grid is speeding up thanks to private investment in storage and renewables. However, success depends on making government approvals faster and solving the environmental issues related to manufacturing.

由於對儲能與可再生能源的私人投資，邁向無碳電網的進程正在加速。然而，成功與否取決於政府審批是否加快，以及是否解決製造相關的環境問題。
