Energy is a basic infrastructure for economic development in Tamil Nadu. Agriculture and industry require infrastructure like irrigation, transportation, machinery, and energy. Energy is the most important single factor constraining economic growth. There is a direct correlation between economic growth, income, and energy consumption. Tamil Nadu relies on both commercial sources like coal, oil, electricity, and non-commercial sources like firewood and agricultural waste for its energy needs. An energy crisis emerged in the 1970s when OPEC hiked oil prices, straining India's imports. To tackle the energy crisis, Tamil Nadu must step up oil production, conserve energy, and expand power generation through sources like bio-diesel, nuclear power, and increased coal production
