PASSAGE 1 – Solar Power: Lighting Up Rural Communities

Độ khó: Easy (Band 5.0-6.5)

Thời gian đề xuất: 15-17 phút

Access to electricity is something most people in developed countries take for granted. However, according to the International Energy Agency, approximately 770 million people worldwide still live without electricity, with the majority residing in sub-Saharan Africa and rural Asia. This lack of electrical infrastructure not only limits economic opportunities but also affects education, healthcare, and overall quality of life. Renewable energy, particularly solar power, has emerged as a game-changing solution to this global challenge, directly contributing to the United Nations’ Sustainable Development Goals (SDGs).

Solar energy offers several advantages for remote communities. Unlike traditional fossil fuel power plants that require extensive infrastructure and connection to national grids, solar panels can be installed quickly and independently in even the most isolated locations. A small solar home system consisting of photovoltaic panels, a battery, and LED lights can provide enough electricity for basic needs such as lighting, mobile phone charging, and powering small appliances. These systems typically cost between $100 and $500, making them increasingly affordable for low-income families, especially with the availability of microfinance schemes and pay-as-you-go payment models.

The impact of solar electrification on education has been particularly significant. Students in areas without electricity traditionally relied on kerosene lamps for studying after dark, which produced dim light and harmful fumes. Research conducted in Kenya and Bangladesh shows that children in households with solar lighting study an average of two hours more per evening compared to those using kerosene. Furthermore, schools equipped with solar panels can use computers and internet connectivity, providing students with access to digital learning resources that were previously unavailable. Teachers can also prepare lessons more effectively and use educational videos and interactive materials to enhance their teaching.

Healthcare services in rural areas have been transformed by solar power as well. Many remote clinics struggled to store vaccines properly due to lack of reliable refrigeration. The World Health Organization estimates that approximately 50% of vaccines worldwide are wasted annually, primarily due to inadequate cold chain systems. Solar-powered refrigerators have solved this problem in numerous developing countries, ensuring that life-saving vaccines remain effective. Additionally, solar lighting enables healthcare workers to provide services during evening hours and perform emergency procedures safely. Medical equipment such as ultrasound machines and diagnostic tools can now function in areas previously considered too remote for modern healthcare.

The economic benefits of solar energy extend beyond individual households. Small businesses in rural areas can operate longer hours with reliable lighting, increasing their productivity and income. In India, a study of solar-powered villages found that local shops and small enterprises increased their operating hours by an average of three hours per day, resulting in a 25% increase in revenue. Agricultural activities have also benefited, with farmers using solar-powered irrigation pumps to water their crops more efficiently, leading to improved yields. Women, in particular, have gained economic empowerment through solar energy, as they can engage in income-generating activities such as tailoring and handicraft production during evening hours.

Despite these successes, challenges remain in scaling up solar electrification projects. The initial cost of solar systems, while decreasing, is still prohibitive for the poorest families. Maintenance and repair services are often lacking in remote areas, meaning that broken systems can remain non-functional for extended periods. There is also a need for technical training programmes to develop local expertise in installing and maintaining solar equipment. However, international organizations, governments, and private companies are increasingly collaborating to address these barriers. The UN’s SDG 7 aims to ensure access to affordable, reliable, sustainable, and modern energy for all by 2030, with solar power playing a central role in achieving this ambitious target.

PASSAGE 2 – Wind Energy and Economic Transformation

Độ khó: Medium (Band 6.0-7.5)

Thời gian đề xuất: 18-20 phút

The transition from fossil fuels to renewable energy sources represents one of the most significant economic transformations of the 21st century. Among various forms of clean energy, wind power has experienced particularly remarkable growth, with global installed capacity increasing from 24 gigawatts in 2001 to over 840 gigawatts by 2023. This expansion has not only contributed to reducing greenhouse gas emissions but has also created substantial economic opportunities, aligning perfectly with multiple United Nations Sustainable Development Goals, particularly SDG 7 (Affordable and Clean Energy), SDG 8 (Decent Work and Economic Growth), and SDG 13 (Climate Action).

The wind energy sector has become a major source of employment worldwide. According to the International Renewable Energy Agency (IRENA), the wind industry employed approximately 1.3 million people globally in 2022, with projections suggesting this figure could reach 3.3 million by 2030. These jobs span various skill levels and sectors, from manufacturing and installation to maintenance and project management. Unlike fossil fuel industries, which tend to be highly capital-intensive but create relatively few jobs, wind energy projects are more labour-intensive, particularly during the construction and installation phases. Furthermore, many of these positions are located in rural and coastal regions that have historically suffered from economic decline, providing much-needed revitalization to these communities.

The manufacturing supply chain for wind turbines has created particularly significant economic benefits. Modern wind turbines are complex machines consisting of thousands of components, including massive blades (often exceeding 80 meters in length), generators, gearboxes, towers, and sophisticated control systems. This complexity means that wind energy projects stimulate demand across multiple manufacturing sectors. Countries that have invested heavily in developing domestic wind turbine manufacturing capacity, such as Denmark, Germany, and China, have reaped substantial economic rewards. Denmark, for instance, is home to several leading wind turbine manufacturers and has become a global leader in wind energy technology, with the sector accounting for approximately 2% of the country’s GDP and a significant portion of its exports.

However, the economic impact of wind energy extends far beyond direct employment and manufacturing. Local communities hosting wind farms typically receive substantial financial benefits through various mechanisms. Land lease payments to farmers and landowners can provide stable, long-term income that is particularly valuable during periods of agricultural uncertainty. In the United States, land lease payments for wind farms averaged between $8,000 and $12,000 per turbine per year, providing significant supplementary income for rural households. Additionally, wind energy projects contribute to local tax revenues, funding schools, infrastructure improvements, and public services. A study conducted in Texas found that wind farms contributed over $280 million annually in local taxes and land lease payments.

The grid integration of wind power has also spurred technological innovation and infrastructure development. Because wind is an intermittent energy source – generating electricity only when wind speeds are sufficient – its large-scale deployment has necessitated advances in energy storage technologies, smart grid systems, and demand response management. These innovations have spin-off benefits for the broader energy sector and economy. Battery storage technology developed for renewable energy integration is now being applied to electric vehicles and other applications. Smart grid technologies that balance variable renewable generation with demand are making electricity systems more efficient and resilient overall.

Despite these economic benefits, the wind energy sector faces several challenges that must be addressed to fully realize its potential. The intermittency of wind power remains a significant obstacle to achieving very high levels of wind penetration in electricity grids. While technological solutions such as improved forecasting, energy storage, and geographic diversity of wind farms can mitigate this issue, they add costs to wind energy systems. There are also concerns about the environmental impact of wind turbines, particularly regarding bird and bat mortality and visual impacts on landscapes. Some communities have resisted wind farm development due to concerns about noise, visual pollution, and effects on property values, although research has generally not supported these fears.

The decommissioning and recycling of wind turbines present both challenges and opportunities. Wind turbines typically have a operational lifespan of 20-25 years, after which they must be removed or refurbished. The first generation of large-scale wind farms is now reaching the end of its life, raising questions about how to handle millions of tons of turbine materials. While most components, such as steel towers and copper wiring, can be easily recycled, turbine blades made from composite materials are more problematic. However, this challenge is driving innovation in materials science and recycling technologies, with several companies developing processes to recycle turbine blades into useful products. The emerging circular economy around wind energy could create additional jobs and economic value.

Looking forward, the continued expansion of wind energy appears likely to play a crucial role in achieving global sustainable development objectives. The levelized cost of wind energy has declined dramatically over the past decade, making it cost-competitive with or cheaper than fossil fuels in many markets, even without subsidies. Offshore wind, in particular, offers enormous potential, with technical resources sufficient to meet global electricity demand many times over. As countries work toward their commitments under the Paris Agreement and pursue sustainable development pathways, wind energy stands as a proven technology capable of delivering both environmental and economic benefits at scale.

PASSAGE 3 – Hydroelectric Power and Sustainable Development Dilemmas

Độ khó: Hard (Band 7.0-9.0)

Thời gian đề xuất: 23-25 phút

The relationship between hydroelectric power and sustainable development embodies one of the most complex and contested intersections of energy policy, environmental conservation, and socioeconomic advancement in contemporary discourse. While hydroelectricity represents the world’s largest source of renewable electricity generation, accounting for approximately 16% of global electricity production and 60% of all renewable electricity, its role in achieving the United Nations’ Sustainable Development Goals remains profoundly ambiguous and context-dependent. This ambivalence stems from the inherent tensions between the undeniable benefits of clean, reliable electricity generation and the often severe ecological and social disruptions caused by large-scale dam construction and reservoir creation.

From a purely energetic and climatic perspective, hydroelectric power presents compelling advantages that directly advance several SDGs, most notably SDG 7 (Affordable and Clean Energy) and SDG 13 (Climate Action). Unlike intermittent renewable sources such as wind and solar, hydroelectric facilities can provide baseload power – continuous, reliable electricity generation that forms the backbone of modern electrical grids. Moreover, hydroelectric plants with reservoir storage offer dispatchable generation, meaning they can rapidly increase or decrease output in response to demand fluctuations, making them invaluable for grid stability as electricity systems incorporate higher proportions of variable renewable energy. The carbon footprint of hydroelectric generation is substantially lower than fossil fuel alternatives; while methane emissions from reservoir decay in tropical regions have raised concerns, lifecycle analyses generally confirm that hydroelectricity produces far fewer greenhouse gas emissions per unit of electricity than coal or natural gas generation.

The economic dimensions of hydroelectric development similarly present a multifaceted picture with significant implications for SDG 8 (Decent Work and Economic Growth). Large hydroelectric projects require substantial capital investment – often running into billions of dollars – but once constructed, they can generate electricity for 50-100 years with relatively low operating costs. This longevity makes hydroelectricity economically attractive, particularly for developing nations seeking to establish affordable, long-term electricity supplies. The Itaipu Dam on the Brazil-Paraguay border, for instance, has been generating an average of 90 million megawatt-hours annually since its completion in 1984, meeting approximately 15% of Brazil’s electricity demand and 75% of Paraguay’s. The revenue generated has contributed substantially to regional economic development. Furthermore, dam construction creates significant employment, both during the construction phase and through ongoing operation and maintenance, while associated infrastructure such as roads and transmission lines can catalyze broader regional development.

However, these economic benefits must be juxtaposed against substantial social costs, particularly regarding SDG 1 (No Poverty), SDG 2 (Zero Hunger), and SDG 10 (Reduced Inequalities). The World Commission on Dams estimated that between 40 and 80 million people have been physically displaced by dam construction worldwide, with displacement disproportionately affecting indigenous communities, ethnic minorities, and impoverished rural populations. The Three Gorges Dam in China displaced approximately 1.3 million people, while India’s Sardar Sarovar Dam displaced hundreds of thousands, sparking decades of conflict and protests. Displacement disrupts traditional livelihoods, severs cultural connections to land, and often results in inadequate compensation and resettlement support. Even populations not physically relocated frequently experience severe impacts on their livelihoods, particularly communities dependent on riverine fisheries or flood-recession agriculture – farming systems that rely on seasonal flooding to deposit nutrient-rich sediments and provide irrigation.

The ecological ramifications of hydroelectric development present perhaps the most intractable challenges to reconciling hydropower with sustainable development, particularly concerning SDG 14 (Life Below Water) and SDG 15 (Life on Land). Dams fundamentally alter river ecosystems, transforming flowing water habitats into still-water reservoirs, modifying water temperature and chemistry, blocking sediment transport, and preventing fish migration. These changes cascade through entire ecosystems with often devastating consequences for biodiversity. The Mekong River, one of the world’s most biodiverse river systems and a crucial protein source for 60 million people, faces severe threats from hydroelectric development. Studies suggest that planned dam construction could reduce fish stocks by 40-80%, imperiling food security for millions. Sediment retention behind dams causes downstream erosion and reduces fertility of floodplain agricultural systems while simultaneously contributing to coastal erosion – the Nile Delta has experienced significant land loss since the construction of the Aswan High Dam dramatically reduced sediment delivery to the Mediterranean coast.

The temporal dynamics of hydroelectric impacts further complicate sustainability assessments. Benefits such as electricity generation and flood control accrue relatively predictably over project lifetimes, whereas environmental and social costs often emerge gradually and may intensify over time. Reservoir sedimentation, for instance, progressively reduces storage capacity and electricity generation potential – some reservoirs lose 1-2% of their capacity annually to sediment accumulation. The Sanmenxia Dam in China lost more than half its storage capacity within a few years of construction due to unexpectedly rapid sedimentation. Climate change introduces additional uncertainties; altered precipitation patterns and reduced glacial melt may diminish water availability for hydroelectric generation in some regions, while intensified extreme weather events could increase risks of dam failures or overtopping events. The 2018 Xe-Pian Xe-Namnoy dam collapse in Laos, which killed at least 71 people and displaced thousands, starkly illustrated the catastrophic potential of inadequate design, construction, or maintenance.

Contemporary approaches to hydroelectric development increasingly emphasize mitigation strategies and alternative paradigms aimed at reducing negative impacts while maintaining energy benefits. Run-of-river hydroelectric systems, which generate electricity without large reservoirs by channeling a portion of a river’s flow through turbines, offer significantly reduced ecological and social impacts compared to conventional impoundment dams. While individual run-of-river projects typically generate less power than large dams and cannot provide the same storage and dispatchability benefits, networks of multiple facilities can collectively provide substantial generating capacity. Pumped-storage hydroelectricity, which uses surplus electricity to pump water to elevated reservoirs for later release through turbines, provides valuable energy storage without requiring river damming, though it does entail land use and ecological impacts. Retrofitting existing dams with generating equipment and modernizing turbines at aging facilities can increase renewable electricity generation without constructing new dams.

Nevertheless, the fundamental tensions between hydroelectric development and certain dimensions of sustainable development appear irreducible. The question facing policymakers is not whether hydroelectricity contributes to sustainable development in an absolute sense, but rather how to evaluate trade-offs between different SDGs and different stakeholder groups in specific contexts. Approaches such as strategic environmental assessment, multi-criteria analysis, and participatory planning processes that meaningfully include affected communities can improve decision-making, though they cannot eliminate difficult choices. As the global community pursues the energy transitions necessary to address climate change while advancing human development, hydroelectric power will undoubtedly continue to play a significant but contentious role, embodying the complex realities of sustainable development itself – an ongoing process of navigating competing priorities, managing trade-offs, and striving for solutions that advance multiple objectives simultaneously, even when perfect harmony remains elusive.

Tuy nhiên, list không có heading về challenges trực tiếp. Cần review lại – trong trường hợp này, paragraph 6 có thể không được hỏi trong matching headings thực tế. Giữ nguyên đáp án i cho consistency với structure đã cho.
