"This dataset provides a comprehensive overview of the natural gas price index system from 2004 to 2024. It includes monthly data on key factors influencing natural gas prices, such as coal prices, crude oil prices, heating oil prices, geopolitical factors, S&P500 index, natural gas supply, consumption, extraction volume, imports, storage levels, maximum and minimum temperatures, heating degree days (HDD), cooling degree days (CDD), and natural gas prices. The dataset covers a 20-year period, offering valuable insights into the trends and patterns of natural gas prices and their relationship with various economic, political, and environmental factors. It serves as a useful resource for researchers, analysts, and policymakers in the energy sector to understand the dynamics of natural gas markets and to develop strategies for energy planning and investment."
