MED 003: Unit 01 – Energy and Development
UNIT 1: ENERGY AND DEVELOPMENT
1.1
Introduction
Energy plays a pivotal role in
shaping the development trajectory of societies across the globe. It is the
driving force behind economic growth, social well-being, and technological
advancement. From powering homes and industries to enabling transportation and
communication, energy is essential to almost every facet
of modern life.
In developing nations,
especially in Asia, the demand for energy is rising exponentially due to
population growth and industrialisation. However, this rising demand raises
critical concerns related to the sustainability of energy resources,
environmental degradation, and the long-term carrying capacity of the planet.
This unit introduces the
linkages between energy and development, explores the trends in energy demand,
and discusses the sustainability of Earth's energy resources.
1.2
Objectives
After studying this unit, you
will be able to:
- Understand the concept of the energy
economy.
- Identify the relationship between energy
demand and population growth.
- Analyze how industrialisation affects
energy consumption.
- Evaluate the energy demand trends in
developing Asian economies.
- Understand the Earth’s energy resource
base and its limitations.
- Recognize the importance of sustainable
energy development.
1.3
The Energy Economy
The energy economy
refers to the sector of a nation's economy that produces, distributes, and
consumes energy. It includes both conventional (coal, oil, gas) and
non-conventional (solar, wind, hydro, nuclear) sources. Energy availability
directly influences productivity, infrastructure development, and quality of
life.
Key aspects of the energy
economy include:
- Energy production (extraction, generation)
- Energy distribution (transmission and infrastructure)
- Energy consumption (by households, industries, transport)
- Energy pricing and subsidies
- Energy security and international trade
The energy economy is closely
tied to macroeconomic indicators such as GDP growth, employment, and foreign
investment. A stable and affordable energy supply is often a precondition for
sustainable development.
1.4
Energy Demand due to Population Growth and Industrialisation
Energy demand is rising
globally, especially in developing regions. The two primary drivers of this
increase are population growth and industrialisation.
1.4.1
Energy Demand vis-à-vis Population Growth
- As population grows, the demand for
electricity, cooking fuel, transportation, and clean water increases.
- Urbanisation adds pressure on centralized
energy grids.
- More housing, hospitals, schools, and
commercial buildings require more energy.
- In many developing countries, the
challenge is not only meeting demand but doing so sustainably and equitably.
Example: India’s population is projected to cross 1.6 billion by 2040, and
energy demand is expected to more than double.
1.4.2
Energy Demand in Industrialisation
- Industrial sectors such as manufacturing,
construction, mining, and heavy engineering are energy-intensive.
- Growth of Small and Medium Enterprises
(SMEs) in developing countries further drives energy consumption.
- As countries industrialise, per capita
energy consumption rises sharply.
Key Insight: The shift from agrarian to industrial economies often leads to a rapid
escalation in fossil fuel usage unless cleaner technologies are adopted.
1.5
Energy Demand in Asian Developing Economies
Asia, home to more than half
the global population, is witnessing a transformation in energy demand:
- China and India are the two largest energy consumers in Asia.
- Countries like Vietnam, Bangladesh,
Indonesia, and Philippines are also experiencing high growth
in energy use.
- Urbanisation, infrastructure projects, and
industrial expansion are major contributors.
Trends:
- Increased dependence on coal, though
renewable energy is gaining traction.
- Energy inequality remains a concern, with
many still lacking access to clean energy.
- Regional cooperation (e.g., SAARC Energy
Ring, ASEAN Power Grid) is emerging as a strategy for energy security.
1.6
The Earth's Energy Resource Base
The Earth provides a vast
range of energy resources, categorized into:
Non-Renewable
Energy Resources:
- Fossil Fuels: Coal, oil, and natural gas—formed over millions of years, finite
in quantity.
- Nuclear Energy: Uses uranium—a limited resource with significant waste management
concerns.
Renewable
Energy Resources:
- Solar Energy: Abundant and increasingly cost-effective.
- Wind Energy: Sustainable with minimal environmental footprint.
- Hydropower: Reliable but can impact ecosystems.
- Biomass and Bioenergy: Can be sustainable if sourced responsibly.
- Geothermal Energy: Locally available in certain geographies.
While the renewable energy
base is vast, it requires technology, investment, and political will to
replace fossil fuels at scale.
1.7
The Carrying Capacity of the Earth's Energy Base
Carrying capacity refers to the Earth’s ability to provide energy resources without
degrading environmental systems or exhausting finite reserves.
Concerns include:
- Resource Depletion: Fossil fuels are being consumed faster than they are replenished.
- Environmental Impact: Emissions from fossil fuels contribute to climate change, acid
rain, and air pollution.
- Ecological Damage: Mining and drilling disturb ecosystems and water resources.
- Waste Generation: Nuclear waste, electronic waste, and industrial by-products pose
long-term hazards.
To remain within the Earth’s
carrying capacity, energy systems must:
- Transition toward cleaner, renewable
sources.
- Focus on energy efficiency and
conservation.
- Encourage behavioral changes in
consumption.
- Enforce policy regulations and
international agreements (e.g., Paris Climate Accord).
Summary
This unit highlighted the
intricate links between energy and development. As population and
industrialisation drive up energy demand, especially in Asia, the challenge
lies in balancing economic growth with ecological sustainability. The Earth
offers a wide range of energy resources, but their usage must be carefully
managed to stay within environmental and ecological limits. Moving toward a
sustainable energy future requires innovation, investment, and global
cooperation.
