The ability of an object or system to carry out tasks or alter its state or environment is referred to as energy. It comes in various forms like heat, light, motion, and electricity. Energy is everywhere, from the food we consume to the fuel used in machinery and cars. The International System of Units (SI) states that joules (J) are used to measure energy. Energy is usually represented by the letter “E” in formulas.
There are two general types of energy:
- Kinetic Energy (K.E)
- Potential Energy (P.E)
Energy comes in different forms that we utilize in our day-to-day activities:
- Thermal Energy (heat)
- Electrical Energy
- Chemical Energy (e.g., in food or batteries)
- Mechanical Energy
- Nuclear Power
- Radiant Energy (light)
We get energy from renewable and nonrenewable sources:
- Renewable Resources: Sunlight, wind, water, geothermal heat, and biomass.
- Non-Renewable Sources: Natural gas, oil, and coal are fossil fuels.
Energy powers homes, industries, transportation, and almost all the systems that make up modern life. Most technologies and comforts we enjoy would be impossible without energy.
