In today's integrated global energy landscape, the connection between domestic energy planning and international energy planning and trading is essential. Domestic demands and priorities influence national energy planning initiatives, which have repercussions on the global scene. In addition to other goals, countries develop energy policies and strategies to guarantee energy security, diversify their energy sources, and lower carbon emissions. The supply and demand dynamics of the world's energy markets are impacted by these national actions. As governments cooperate on energy security, work on cross-border infrastructure projects, and discuss energy trade agreements, international energy planning is necessary. Additionally, it promotes geopolitical linkages and economic collaboration. But it also brings with it complications relating to market rules, geopolitical conflicts, and environmental concerns.
