Energy is vital for economic growth and is measured by per capita power consumption. India ranks 8th globally in total power consumption. Energy auditing and management are important to minimize fossil fuel usage and emissions, cut investment costs, and improve efficiency. Renewable energy sources like solar and wind are growing significantly in India's energy mix due to policies promoting their development and use. The Electricity Act of 2003 aims to develop the electricity sector through private participation, competition, and regulatory oversight.

Ep = [ mass x gravitational acceleration x height ]
The various form of potential energy are:
(i) Chemical Energy
(ii) Nuclear Energy
(iii) Stored Mechanical Energy
(iv) Gravitational Energy

10. (i) Chemical Energy:
 Energy stored in the bonds of atoms and
molecules and released as heat in a chemical
reaction
 Expressed as kJ / kg or kJ / mol
 Some examples are : biomass, petroleum, coal ,
propane and natural gas.

• Primary energy is transformed in energy
conversion process to more convenient form
of Secondary Energy such as steam and
electricity.
Secondary Energy is the extracted
product of Primary Energy

19. VARIOUS PRIMARY AND SECONDARY
ENERGY RESOURCES

20. COMMERCIAL ENERGY
 Energy that is available in the market for a
definite price
 No matter what the method of energy
production
 The most pre dominant commercial energies
are Electricity, Coal, Refined Petroleum
Products and Natural Gas

21. NON – COMMERCIAL ENERGY
• Any kind of energy which is sourced within a Community
and its surrounding area and not normally traded in the
commercial market.
• Non – commercial energy is often ignored in compiling a
country ‘s energy statistics.
• They are also called as traditional fuels
• Some of non - commercial energy are
 Firewood and agro in rural area
 Solar energy for water heating, drying grain and fish
 Animal power for transport, lifting and irrigation
 Wind energy for water lifting and electricity generation

22.  Renewable energy is
the energy obtained
from natural sources
which are essentially
inexhaustible
 It can be utilized without
release of harmful
pollutants
