Top 10 Energy Facts You Should Know

1. Energy Cannot Be Created or Destroyed

According to the law of conservation of energy, energy only changes form, such as from chemical to electrical or mechanical energy.

2. The Sun Is Earth’s Main Energy Source

Nearly all energy on Earth, including wind, fossil fuels, and food energy, ultimately comes from the Sun.

3. Renewable Energy Is Growing Rapidly

Solar, wind, and hydropower are among the fastest-growing energy sources worldwide due to sustainability efforts.

4. Fossil Fuels Took Millions of Years to Form

Coal, oil, and natural gas formed from ancient plants and organisms over millions of years under heat and pressure.

5. Energy Efficiency Saves Money and Resources

Using energy-efficient appliances reduces electricity consumption and lowers environmental impact.

6. Electricity Is Not an Energy Source

Electricity is a carrier of energy that must be generated from other sources like coal, water, wind, or sunlight.

7. Nuclear Energy Produces Low Carbon Emissions

Nuclear power generates large amounts of electricity with minimal greenhouse gas emissions during operation.

8. Energy Demand Is Increasing Globally

Population growth and technological development are driving higher energy consumption worldwide.

9. Batteries Store Energy, Not Power

Batteries store chemical energy and release it as electrical energy when needed.

10. Energy Use Impacts Climate Change

Burning fossil fuels releases greenhouse gases that contribute significantly to global warming.
