RENEWCONNECT - All about renewables & power sector

A hybrid energy system (HES) integrates multiple energy sources, typically combining renewable energy technologies like solar, wind, hydro, and biomass with conventional power generation methods to optimize energy efficiency, reliability, and cost-effectiveness. The key aim of HES is to reduce dependency on a single energy source, enhance energy security, and support decentralized power generation. Hybrid Energy Systems: An Overview Hybrid energy systems are designed to blend different energy generation methods to maximize output and efficiency. These systems can be grid-connected or off-grid, providing flexibility in power supply. The combination of renewable sources—solar, wind, hydro, and biomass—alongside conventional energy (e.g., diesel generators or natural gas) allows for a more resilient and reliable power supply, especially in regions with variable renewable energy availability. The Need for Decentralization in India India's ambitious renewable energy targets, particularl...

Dhanbad Coal mines in India Introduction Coal mining, a practice essential to powering the world’s energy needs, comes in two main types: open-pit (or open-cast) and underground (or closed) mining. These methods of coal extraction have left vast expanses of land transformed by mining activities, and as coal reserves deplete, many mines are eventually exhausted. However, these sites present opportunities for repurposing, particularly for renewable energy projects like pumped hydro storage, which can play a significant role in maintaining energy balance as we transition away from fossil fuels. Globally, coal mining has a significant footprint. As of 2024, 29 countries are actively involved in coal mining, with India being one of the leading producers. However, many mines across these regions have reached the end of their productive lives, resulting in either closures or abandonment. These exhausted mines pose environmental challenges but also provide a unique opportunity for sustainable ...
