Types of Energy

Energy exists in two primary forms: renewable and non-renewable.

  • Non-renewable Energy: Non-renewable energy sources encompass coal, gas, and oil. These are extensively used in vehicles like cars, trains, and planes. They are produced by burning fossil fuels to generate energy.
  • Renewable Energy: Renewable energy includes solar, hydro, and wind energy. Wind power, for example, is harnessed by the movement of wind turbine blades, which converts this motion into electrical energy.
