energy is supplied by

Energy can be supplied by various sources and methods, depending on the context in which the question is asked. Here are some common sources of energy:

1. Fossil Fuels: This category includes coal, natural gas, and oil. Energy is released from these materials when they are burned.

2. Nuclear Energy: Using nuclear reactions, such as fission or fusion, to generate heat, which is then used to produce electricity.

3. Renewable Energy: This includes sources that are replenished naturally, such as solar power, wind power, hydroelectric power (from water currents), geothermal energy (from the heat of the earth), and biomass (from organic materials).

4. Battery/Chemical Energy: Chemical reactions in a battery can produce electrical energy, which is used to power electronics and electric vehicles, among other applications.

5. Mechanical Energy: Generated through physical movement, like when a wind turbine turns to generate electricity or when a person turns a crank to power a light
