Microgrids: The Emerging Trend in Distributed Energy Systems
The Growing Need for Disruption in the Energy Sector
The traditional centralized power grid has been the backbone of the energy sector for decades. However, with the increasing demand for renewable energy, rising concerns about climate change, and the need for greater energy resilience, the energy landscape is evolving rapidly. Microgrids have emerged as an innovative solution to address these challenges, offering a more efficient, sustainable, and decentralized approach to energy generation and distribution.
