Energy supply refers to the provision of energy resources that power homes, industries, and transportation. This includes various sources such as fossil fuels, renewable energy, and nuclear power. Each source has its own methods of extraction, generation, and distribution, impacting both the environment and economy. The energy supply system involves a network of production, transmission, and consumption. Electricity is generated at power plants and delivered through power grids to consumers. Efficient energy supply is crucial for maintaining modern lifestyles and supporting economic growth while addressing challenges like climate change and resource depletion.
