V. TASK ASSIGNMENT TABLE................................................................................28 8 I. INTRODUCTION
In the face of escalating environmental concerns and growing ener gy demands,
renewable energy has become a cornerstone in the pursuit of sustainable development. By
harnessing natural resources such as sunlight, wind, and water , renewable energy
provides cleaner and more reliable alternatives to fossil fuels, offering pathways to
mitigate climate change and secure long-term energy stability. Its importance is not only
technological but also economic and social, as it directly contributes to shaping a greener and more resilient future.
In this group discussion, we will explore renewable energy through five
interconnected dimensions. First, we will clarify the fundamental concepts to establish a
clear understanding of the topic. Second, we will classify the major types of renewable
energy, examining their distinctive features. Third, we will highlight the differences
between renewable and non-renewable sources, emphasizing their impacts on
sustainability. Fourth, we will analyze the costs and benefits associated with renewable
energy adoption. Finally, we will address the challenges that hinder its development and
propose viable solutions for the future. By following this outline, our discussion aims to
provide a comprehensive and insightful perspective on renewable energy and its role in
shaping the future of global energy systems. 9 II. CONTENT 1. Concepts
1.1. Definition of Renewable Energy
Renewable energy refers to energy derived from natural processes that are
continuously replenished on a human timescale. Unlike fossil fuels, which take millions
of years to form, renewable sources are available in cycles that ensure their ongoing
availability. In academic and policy contexts, renewable energy is defined as energy
generated from resources such as sunlight, wind, water flows, and biological matter. This
definition emphasizes sustainability, accessibility, and the ability to meet human needs
without exhausting the planet’s finite reserves.
1.2. Origin and Sources
The origins of renewable energy are rooted in the Earth's natural systems, primarily driven
by solar radiation, the planet's internal heat, and gravitational forces. These
fundamental forces power all renewable sources.
- Solar Radiation: The sun is the ultimate source for most renewable energy forms. It
directly provides solar energy and indirectly drives the weather patterns that create wind
energy, as well as the water cycle for hydropower and biomass growth.
- Geothermal Heat: This energy comes from the Earth's molten core, a constant source of heat that can be harnessed.
- Gravitational Forces: The gravitational pull of the moon and sun creates tides, which are used to generate tidal energy.
These origins are the foundation for the diverse range of renewable sources we use
today, including solar, wind, hydro, geothermal, and biomass.
1.3. Core Characteristics
Renewable energy is defined by several essential characteristics that set it apart from
conventional energy sources. First, it is replenishable, as natural processes such as
sunlight, wind, and hydrological cycles restore these resources continuously on a human 10
timescale. Second, it is widely available, though its intensity and accessibility vary across regions depending
on geography and climate. Third, renewable energy is generally
environmentally benign, producing minimal greenhouse gas emissions during use and
contributing less to air and water pollution compared to fossil fuels. Finally, renewable
systems often support decentralized generation, allowing households, communities, and
local enterprises to participate directly in energy production. These defining features
explain why renewable energy is central to modern energy transitions and global sustainability strategies.
1.4. Global Significance
Renewable energy holds profound global significance as a cornerstone for addressing
pressing planetary challenges, including climate change mitigation and energy security. It
plays a pivotal role in reducing carbon dioxide emissions, aligning with international
agreements like the Paris Accord to limit global warming. Economically , it drives
innovation, job creation, and investment, with projections indicating it could supply the
majority of the world's electricity by mid-century, bolstering sustainable growth in both
developed and developing nations. On a societal level, renewables enhance access to
affordable energy in remote areas, promoting equity and poverty alleviation while
safeguarding biodiversity and public health. Ultimately , its widespread adoption
represents a transformative pathway toward a resilient, low-carbon future, underscoring
humanity's commitment to harmonious coexistence with the environment.
2. Classification of Renewable Energy
2.1 Solar energy
Solar energy is the power derived from sunlight, captured through solar panels and
technologies to produce electricity, heat, or fuel. It is one of the most abundant and
accessible renewable energy sources, available in nearly every region of the world. Solar
energy can be harnessed in two main ways. Photovoltaic (PV) systems directly convert
sunlight into electricity using semiconductor materials, most commonly silicon. Solar
thermal systems, on the other hand, use mirrors or lenses to concentrate sunlight and 11
generate heat, which can then be used for industrial processes, heating, or electricity
production through steam turbines. Solar ener gy is
clean, inexhaustible, and scalable—from rooftop systems on
households to utility-scale solar farms. Technological advancements and falling panel
costs have made it one of the fastest-growing energy sources. However, its intermittency
(dependence on sunlight) requires storage systems such as batteries or integration with
other energy sources to ensure stable supply.
China leads the world in installed solar capacity, followed by countries like the
United States, India, and Germany. Europe has long been a pioneer in solar adoption,
particularly Germany and Spain. In Southeast Asia, Vietnam has emerged as a leader,
especially in Ninh Thuan and Binh Thuan provinces, where large-scale solar farms take
advantage of favorable sunlight conditions.
2.2. Wind energy Wi nd energy is generated
by converting the kinetic energy of moving air into
mechanical and then electrical power using wind turbines. It is one of the oldest forms of
renewable energy, historically used for sailing and milling, but today applied at industrial
scale for electricity production.
Wind energy is produced through the following process: modern wind turbines consist
of large blades mounted on tall towers. When wind moves across the blades, it creates lift
and causes them to rotate. This mechanical motion drives a generator inside the nacelle,
converting the kinetic energy of the wind into electricity. Wind energy is deployed both
onshore (land-based) and offshore (sea-based), with offshore turbines benefiting from
stronger and more consistent winds.
Wind power is clean, cost-effective, and increasingly competitive with fossil fuels.
Offshore wind farms provide high energy yields, while onshore wind remains more
widespread due to lower installation
costs. Challenges include variability of wind
resources, land use concerns, and impacts on local ecosystems, though modern designs
continue to mitigate these issues. 12
China and the United States are the largest producers of wind energy, with Germany,
Denmark, and the UK playing key roles in offshore development. Denmark is often cited
as a pioneer in offshore wind technology. Vietnam has significant wind energy potential,
particularly in coastal provinces like Binh Thuan and Soc Trang, where both onshore and
offshore projects are being actively developed. 2.3. Hydropower
Hydropower, or hydroelectric power, is a renewable source of energy that generates
power by using a dam or diversion structure to alter the natural flow of a river or other
body of water. Hydropower relies on the endless, constantly recharging system of the
water cycle to produce electricity, using a fuel—water—that is not reduced or eliminated in the process.
Because hydropower uses water to generate electricity, plants are usually located on
or near a water source. The energy available from the moving water depends on both the
volume of the water flow and the change in elevation—also known as the head—from
one point to another. The greater the flow and the higher the head, the more the electricity
that can be generated. Water flows through a pipe—also known as a penstock—and then
spins the blades in a turbine, which, in turn, spins a generator that ultimately produces
electricity. Most conventional hydroelectric facilities operate this way, including run-of-
the-river systems and pumped storage systems.
Hydropower is highly developed in countries with abundant water resources. China
leads the world with over 390 GW of installed capacity, followed by Brazil, the United
States, Canada, and India. In Norway, hydropower generates about 90% of the country’s
electricity, while in Brazil it accounts for more than 55%. Many African and Asian
countries, such as Ethiopia and Laos, are expanding large-scale projects to meet rising
electricity demand. However, environmental concerns, including ecosystem impacts and
community displacement, remain challenges worldwide. 13
2.4. Biomass and Geothermal Energy
a. Biomass Energy
Biomass is a versatile renewable energy source. It can be converted into liquid
transportation fuels that are equivalent to fossil-based fuels, such as gasoline, jet, and
diesel fuel. Bioenergy technologies enable the reuse of carbon from biomass and waste
streams into reduced-emissions fuels for cars, trucks, jets and ships; bioproducts; and renewable power.
The chemical energy stored in biomass is converted into usable energy through
processes like combustion (burning to produce heat or electricity), anaerobic digestion
(producing biogas), or conversion into biofuels (e.g., ethanol, biodiesel).
Biomass energy is widely used in both developed and developing countries. In the
European Union, it accounts for nearly 60% of renewable energy consumption, with
countries like Sweden, Finland, and Germany leading in modern bioenergy use. Brazil is
a global leader in biofuels, producing ethanol from sugarcane to power vehicles, while
the United States relies heavily on corn-based bioethanol. In Asia, countries such as
China and India are promoting biomass for electricity and rural heating. Despite its
potential, issues of land use and sustainability still require careful management.
b. Geothermal energy:
Geothermal energy refers to the natural thermal energy in the Earth’s interior that
is brought to the surface by technological methods and utilized in different fields. Deep in
the Earth’s interior, magma-heated water and vapor sources form geothermal energy
under high temperature and pressure; this ener
gy is utilized in many sectors from
electricity generation to heating systems with the help of special equipment and techniques.
Geothermal energy generates energy using the heat of hot rocks, magma or hot water
layers beneath the earth’s crust. These heat sources have a constant temperature profile, providing reliable ener
gy infrastructure all year round. These systems are based on 14
bringing high-temperature steam to the surface and using it for ener gy conversion processes.
Deep wells are drilled to reach these hot springs underground and these wells are
equipped with high temperature resistant pipe systems. After the hot water or steam is
brought to the surface, turbines and generators are activated, which convert the energy of
the steam into mechanical movement, and then into electrical energy. After the cooling
process, water that has turned into a liquid state is injected underground again, creating a sustainable
cycle. The design and operation stages of these systems are of critical
importance for stable and efficient energy production
Geothermal power is concentrated in geologically active regions. The United States is
the global leader with nearly 4 GW of installed capacity, followed by Indonesia, the
Philippines, Turkey, and New Zealand. Iceland is a standout case where geothermal
provides about 25% of electricity and nearly 90% of heating needs. Kenya has also
emerged as Africa’s top geothermal producer, with projects in the Rift Valley supplying a
large share of national power. While high upfront costs limit expansion in some areas,
countries with active tectonic zones continue to invest heavily.
3. Differences between Renewable and Non-Renewable Energy Sources
3.1. Definition and Availability a. Definition Renewable ener
gy comes from natural sources that continuously replenish
themselves. Unlike finite fossil fuels, these energy sources won't run out. The primary
types include solar, wind, hydro, geothermal, and biomass.
Non-renewable energy comes from sources that cannot be replenished within a
human lifetime. These include fossil fuels (coal, oil, natural gas) and nuclear energy
(though sometimes categorized separately). These resources formed over millions of
years and once used, cannot be quickly replaced. b. Availability 15
Renewable energy is inherently reliant on seasonal and climate variation. If there is no
wind blowing, there is no wind energy to capture, and if there is no sun shining, there is
no solar energy to capture. This unpredictability is one of the major concerns regarding
renewable energy. Yet, energy storage systems and options like green hydrogen can play a role in reducing this issue
Non-renewable resources are not reliant
on short-term conditions and remain
accessible regardless of weather and climate patterns. This makes them desirable for
many industries that require continual on-demand energy , like steel and cement production.
3.2. Environmental Impact
Renewable energy sources have minimal environmental impact. Their primary
impacts are related to infrastructure production, transportation and installation. After
installation, they produce little-to-no greenhouse gas emissions. This is one of the main
reasons they will play an essential role in the world’s future energy mix.
In contrast, non-renewable energy produces large quantities of greenhouse gases and
pollution throughout its life cycle. Fossil fuels are the leading cause of climate change
and have led to the highest rate of atmospheric carbon dioxide in the last 5 million years.
Solar and wind power, for example, provide electricity without releasing any toxins or
emissions, in contrast to fossil fuels. Without contributing to global warming or other
harmful atmospheric pollutants, solar panels and
wind turbines respectively collect
energy from the sun’s rays and the wind. So, throughout their useful lives, renewable
energy systems leave much less of an ecological impact than conventional power plants.
3.3.Reliability and Accessibility
Reliability and accessibility determine how dependable energy is for daily life and
industrial use. Renewable energy often depends on natural conditions such as sunlight,
wind, or rainfall, which makes it vulnerable to interruptions. For example, solar power only functions during the day , and
wind power varies with weather patterns.
Geographical limitations are also evident, since hydropower requires suitable river 16 systems and geothermal ener gy depends
on volcanic areas. Nevertheless, recent
advancements in energy storage and smart
grids have improved the reliability of
renewables. In terms of accessibility, the high initial investment can be a barrier, yet once
installed, renewable systems provide decentralized power that benefits rural and remote regions.
Non-renewable energy sources present a different picture. They provide a consistent
and predictable supply, largely unaffected by weather conditions. Their reliability is reinforced
by a long-established global infrastructure that ensures extraction,
transportation, and distribution. However
, accessibility is not without problems, as
countries without domestic reserves must rely on imports, leaving them vulnerable to
market fluctuations and geopolitical instability.
At present, non-renewable sources have the upper hand due to their stable supply and
strong infrastructure. Still, renewable energy is catching up quickly, offering flexible
solutions supported by new technology and localized access.
3.4. Long-term Sustainability
When it comes to sustainability, renewable energy has clear advantages. It produces
very low greenhouse gas emissions, protecting the environment from climate impacts.
More importantly, it is based on inexhaustible resources such as sunlight, wind, and water
, which ensures long-term availability
. The falling cost of production and the
creation of green jobs also make renewables increasingly attractive. Yet challenges
remain, particularly in the resource-intensive production of solar panels and wind
turbines, as well as land-use conflicts for large-scale projects.
Non-renewable energy sources, by contrast, are finite and will eventually run out.
Their use has been linked to serious environmental problems, including air pollution,
water contamination, and greenhouse gas emissions. Economically, they are unstable due
to price volatility and limited reserves. Nuclear energy avoids carbon emissions but poses
other difficulties, such as radioactive waste and the risk of accidents. 17
Renewable energy is the only truly sustainable solution, since it relies on unlimited
natural resources and causes less damage to the environment. Non-renewables, although
useful for present needs, cannot provide a secure or clean future because of depletion and pollution.
4. Costs and Benefits of renewable energy
4.1 Costs of Renewable Energy.
- Capital Investment and Infrastructure :
One of the major challenges of renewable energy lies in its high upfront capital
requirements. The installation of solar panels, wind turbines, hydroelectric dams, and
transmission lines demands significant financial resources. However, once these systems
are in place, operation and maintenance costs are generally lower than those of fossil fuel
plants—solar and wind energy in particular have minimal running expenses since they do not rely
on continuous fuel supplies. Cost efficiency also depends heavily on
geographical and climatic conditions—solar energy is more affordable in sunny regions,
while wind power is most effective in areas with consistent wind patterns. In addition,
government policies such as subsidies, tax credits, and financial incentives play a
decisive role in reducing the effective cost of renewable deployment.
- Price Competitiveness Compared to Fossil Fuels :
Renewable energy has become increasingly competitive with traditional fossil
fuels. According to a 2025 IRENA report, 91% of newly commissioned utility-scale
renewable projects globally in 2024 generated electricity at a lower cost than the cheapest fossil fuel alternative . (Ener
gy Tracker Asia) Solar photovoltaics (PV) averaged
$0.043/kWh, about 41% cheaper than fossil fuel options, while onshore wind was even
cheaper, at around $0.034/kWh, about 53% cheaper, per the same report. (TaiyangNews - All About Solar Power)
Another major advantage is the absence of ongoing fuel purchases, which reduces
long-term costs. Fossil fuels carry hidden external costs such as air pollution, greenhouse
gas emissions, and public health expenditures. Renewables avoid most of these, which 18
improves their economic and environmental sustainability . Moreover , in 2024,
renewables helped avoid an estimated USD 467 billion in fossil fuel costs globally. (Energy Tracker Asia)
- Global Trends and Future Outlook :
Global trends show a rapid decline in renewable energy costs over the past decade.
For example, between 2010 and 2024, the total installed cost (TIC) for solar PV dropped
to about USD 691/kW, and for onshore wind to about USD 1,041/kW, reflecting large
reductions in module cost, system components
, and installation “soft costs”.
(TaiyangNews - All About Solar Power) Battery storage costs have also plummeted—
around 93% decline since 2010, dropping to approximately USD 192/kWh in 2024. (Renewable Market Watch)
Projections suggest that renewables will increasingly dominate global electricity supply
in the next decade or two, as technology continues to improve and policy support remains
strong. Although challenges such as energy storage limitations, grid infrastructure, and
financing in developing regions still remain, these cost trends make the case strong that
renewables are becoming the most cost-effective and sustainable energy option for the future.
4.2 Benefits of renewable energy - Environmental Impact :
One of the most compelling reasons to transition to renewable energy is its
positive effect on the environment. Unlike traditional fossil fuels, renewable sources such
as solar, wind, hydro, and biomass emit little to no carbon dioxide (CO ), ₂ which is the
primary greenhouse gas responsible for global warming. This reduction in greenhouse
gas emissions plays a crucial role in mitigating climate change and its associated impacts,
such as extreme weather events. According to the International Energy Agency (IEA),
renewable energy helped avoid around 550 million tons of CO ₂emissions in 2022—
equivalent to the entire annual emissions of the European Union’s transportation sector. 19
By relying on renewables, we can curb global warming and reduce the adverse effects of air pollution.
Moreover, renewable energy improves air and water quality. The burning of coal
and oil not only releases harmful emissions but also contributes to smog, acid rain, and
water contamination. In contrast, solar and wind energy production does not generate
harmful pollutants, leading to cleaner air and water. This, in turn, has direct health
benefits for the population. For instance, in the United States, the Environmental
Protection Agency (EPA) estimates that improvements in air quality from clean energy
sources could save $30–100 billion annually in healthcare costs. Additionally, large-scale
investments in solar and wind energy in China have already led to noticeable reductions
in air pollution levels, particularly in cities like Beijing.
Renewable energy also helps conserve natural resources. Unlike fossil fuels,
which are finite and require destructive mining and drilling, renewable sources are
sustainable and replenishable. The Kamuthi Solar Power Project in India, one of the
world’s largest solar parks, is an excellent example of how renewable energy can reduce
reliance on coal mining, thereby preserving ecosystems and natural resources.
- Energy Independence and Security :
Another significant advantage of renewable energy is the potential for energy
independence and improved security. Many countries currently rely on imported fossil
fuels, making them vulnerable to price fluctuations, supply disruptions, and geopolitical
conflicts. By investing in renewable ener
gy infrastructure, nations can reduce their
dependence on imported oil and gas, thus enhancing their energy security.
For example, after the 2022 Russia–Ukraine crisis, Germany accelerated its investments
in wind and solar energy to lessen its reliance on Russian natural gas. This shift has
helped Germany stabilize its ener
gy supply and protect itself from external shocks.
Furthermore, renewable energy sources tend to have low operating costs once the
infrastructure is in place, offering long-term price stability. In the United States, the cost
of wind power has dropped by over 70%, while solar energy costs have decreased by 20
