2. Energy security is essential for
welfare increases and sustainable
development.
Similar to food and water, energy is
a basic requirement for survival of
the nations.
Today, more than ever, energy
resources are the main driving force
not only in the world economy, but
also in international politics.
That’s why, energy security is big
concern for the nation.
.
INTRODUCTION
3. To achieve energy security, a country must have access to a reliable and diverse mix
of energy sources, including fossil fuels, nuclear power, and renewable energy.
In order to fully understand what constitutes the very meaning of energy security, it’s
necessary to go through its 4 A’s :
Accessibility
Availability
Acceptability
Affordability
Energy security is perceived differently by different people and in different contexts.
For example, while some see energy security as a serious policy issue, others view
the power of the oil market, and not oil itself, as the force that actuates the state of
energy security.
We define energy security as the uninterrupted process of securing the
amount of energy that is needed to sustain people’s lives and daily activities
while ensuring its affordability.

LANDSCAPE
Oil, coal, and
natural gas account
for the majority of
global energy
supply, with China,
the United States,
and Russia being
the largest
producers.
Nuclear power
provides about
10% of global
energy supply, with
France, the United
States, and China
being the largest
producers
Renewable energy
sources such as
wind, solar, and
hydro power are
growing rapidly,

5. IMPORTANCE OF ENEGY
SECURITY
Energy security is important due to economic, social, and environmental reasons.
Environmental sustainability is also a key concern in energy security. Achieving
energy security requires using cleaner energy sources with less environmental
impact such as reducing greenhouse gas emissions and promoting renewable
energy sources.
Energy security is an essential aspect for economic growth and development.
Achieving energy security is necessary to support industrial activity, power
businesses, and drive economic growth. Energy insecurity can lead to higher
energy prices, hurting businesses and consumers.
6. It is also important for social stability. Achieving energy security is necessary to
support human activities like cooking, heating, and transportation. On the other
hand, energy insecurity can lead to social unrest, conflict and even war.
It also contributes to a country’s economic growth, political stability, and overall
development and security of other sectors such as agriculture and manufacturing.
Achieving energy security is therefore a crucial component of national security.
Energy security ensures a stable supply of energy and sustainability of humans’
basic needs which is critical for the functioning of modern societies and economies.

7. FACTORS AFFECTING ENERGY
SECURITY
• It is essential for energy security because it
ensures a country can develop and
maintain its energy infrastructure.
Political stability
• It can improve energy efficiency and lead to
the development of new energy sources.
Technological
innovation
• It drives energy demand and can lead to
energy insecurity if not managed properly
Economic growth
• It reduces energy demand and helps to
ensure energy security.
Energy
conservation
8. STRATEGIES FOR ACHIEVING
ENERGY SECURITY
Energy Efficiency
Improving energy efficiency
reduces the amount of
energy needed to meet
energy demand, increasing
overall energy security.
Energy-efficient building.
Lead to more efficient
transportation systems.
Give rise to efficient
industrial processes
Diversification of
Energy Sources
Diversifying energy sources
reduces dependence on any
one source and increases
resilience to supply
disruptions.
Developing renewable
energy sources, reducing
reliance on fossil fuel.
Expanding nuclear power
capacity
Exploring new alternative
energy sources
Energy storage help to
overcome intermittency
of renewable energy
sources and enable
energy to be used when
needed.

9. GLOBAL ENERGY BALANCE
Global energy balance refers to the delicate equilibrium between the
energy received from the sun and the energy radiated back into space by the
Earth.
It is a fundamental concept in understanding the functioning of our planet's
climate system.
The energy balance determines the distribution of heat across the Earth's
surface and influences weather patterns, ocean currents, and the overall
climate.
Maintaining a stable global energy balance is crucial for the sustainability of
our environment and the well-being of life on Earth
10. COMPONENTS OF GLOBAL
ENERGY BALANCE
• The Earth receives energy from the sun in the form of solar radiation,
primarily in the form of visible light and infrared radiation.
Incoming
Solar
Radiation
• A portion of the incoming solar radiation is reflected back into space by the
Earth's atmosphere, clouds, and the planet's surface
Reflected
Sunlight
• The Earth absorbs a significant amount of solar radiation, particularly by the
land, oceans, and atmosphere
Absorbed
Solar
Radiation
• Some of the absorbed energy is radiated back as longwave infrared radiation.
• Greenhouse gases trap a portion of this outgoing radiation, causes
greenhouse effect, which helps regulate Earth's temperature.
Greenhouse
Effect
• The remaining energy that is not absorbed or trapped by greenhouse gases is
radiated back into space as outgoing longwave radiation
Outgoing
Longwave
Radiation
11. The balance of incoming and outgoing heat on Earth is referred to as its energy
budget.
The energy budget is closely related to the global energy balance as it
represents a quantitative assessment of the inflows and outflows of energy
within the Earth's climate system
