Achieving this will require the energy system to incre asingly rely on renewable energy sources\, such as wind and solar\, whose variable and intermittent nature poses challenges to balancing electricity supply and demand. An integrated approach to energy management across sec tors\, such as electricity\, natural gas\, and hydrogen\, has the potentia l to harness the synergies and complementarities among these energy carrie rs and facilitate the integration of renewable energy sources.
