An energy crisis is a situation in which the demand for energy exceeds the supply. It can refer to shortages of oil and other fossil fuels, electricity, or other forms of energy. Energy crises can have a major impact on the economy and social well-being of a nation. Common causes of energy crises include conflict and war, supply disruptions due to natural disasters or sabotage, and market manipulation. Solutions to an energy crisis depend on its cause, but often involve increased conservation, increased production of energy, or increased imports of energy from other countries.
