Define energy also mention the different forms of energy.
Energy is the ability to do work . The SI unit of energy is Joules (J) which is nothing but a term for Newton-meter.
Different forms of energy are.
1. Solar energy
The light and heat from the sun, harnessed using technologies like, solar heating, photovoltaic, solar thermal energy, solar architecture, and artificial photosynthesis is known as solar energy. It is the prime source of renewable energy
2. Wind Energy
It is one of the various forms of energy. The energy present in the flow of wind, used by wind turbines is called wind energy. This energy is a major cheap source to produce electricity. In this phenomena, the kinetic energy of the wind is converted into mechanical power.
3. Nuclear energy.
The energy present in the nucleus of an atom is known as nuclear energy. The particles of an atom are tiny and need the energy to hold themselves. Nuclear energy is that enormous energy in the bonds of an atom which helps to hold the atom together. Nuclear energy can be used to make electricity.
4. Geothermal energy.
The energy or heat present inside the Earth is known as geothermal energy. It is a cheap & convenient heat and power resource and use of this energy don’t have a side effect like greenhouse gas emission etc.
5. Tidal energy.
Tidal energy or tidal power is a form of hydropower (energy present in water), which converts the energy present in the tides to produce electricity.
6. Biomass
Biomass is organic matter obtained from living organisms. The energy produced from biomass is called biomass energy.
7. Electrical energy
The energy caused by moving electric charges is known as electrical energy. Electric energy is a type of kinetic energy as the electrical charges moves.
8. Thermal energy.
As the name suggests, thermal energy is the energy obtained from heat. It is a microscopic, disordered equivalent of mechanical energy.
NB: K.E. and P.E. are types of energy not forms of energy.Regards......
