The National League of Cities (NLC) has developed a comprehensive guide to empower local leaders in making informed decisions regarding energy resources for sustainable development. The guide includes fact sheets on geothermal, nuclear, hydrogen, batteries, and carbon capture technologies. Geothermal energy, sourced from the Earth's interior, and nuclear energy, generated through controlled reactions, offer benefits like low carbon emissions and reliability. Hydrogen energy, as a clean fuel for various applications, provides versatility and energy storage capabilities. Carbon capture and storage (CCS) technologies aid in emission reduction and industrial decarbonization. Batteries and energy storage systems contribute to grid stability, renewable energy integration, and backup power. Each energy resource presents both benefits and considerations, such as initial costs, safety concerns, infrastructure development, and technological advancements. The guide emphasizes the need for local officials to understand these factors to develop effective energy policies that align with sustainability and community needs. By leveraging these resources strategically, communities can foster economic growth, attract businesses, and build resilient infrastructures. In conclusion, the NLC's guide equips city leaders with essential knowledge to navigate the evolving energy landscape and drive sustainable development initiatives.
