Energy security refers to the reliable availability of energy resources at an affordable price. It involves ensuring that a country has access to sufficient energy supplies to meet its needs, which can include electricity, heating, and transportation fuels. This concept is crucial for maintaining economic stability and supporting everyday life. To achieve energy security, nations often diversify their energy sources, investing in renewable energy like solar and wind, as well as traditional sources such as natural gas and oil. Additionally, energy security involves strategic planning to protect against disruptions, such as geopolitical conflicts or natural disasters, that could impact energy supply.
