GS Paper: GS3

  • India is now Third-Largest Producer of Solar Power

    Why in the News? 

    In 2023, India overtook Japan to become the world’s third-highest producer of solar power, according to a report by the International Energy Analytics Agency Ember.

    Global Solar Energy Production:

    • The leading producer of solar power in the world is China which produced 584 BU of solar power in 2024 – more than the next four countries combined (the United States, Japan, Germany and India).
    • India generated 113 billion units (BU) of solar power in 2023 compared to Japan’s 110 BU.
      • The installed solar energy capacity has increased by 30 times in the last 9 years and stands at 81.81 GW as of Mar 2024.
      • India’s solar energy potential is estimated to be 748 GWp as estimated by National Institute of Solar Energy (NISE).
    • Power demand in Japan decreased by 2% (2 BU) in 2023 after rising in 2021 and 2022, thus allowing India to overtake Japan.

    Other factors to make India the third-largest Solar power producer in 2023:

    • Government Initiatives: India has implemented various policies and initiatives to promote renewable energy, particularly solar power.
      • The government launched the Jawaharlal Nehru National Solar Mission (JNNSM) in 2010, aiming to promote the development and use of solar energy in the country.
      • Subsequently, various state-level policies and incentives were introduced to encourage solar power generation.
      • For example Gujarat Solar Energy Policy (Target is 36 GW of solar energy by 2036).
    • Investment and Financing: There has been significant investment in the solar power sector in India, both from domestic and international sources.
      • For example PM Surya Ghar, Muft Bijli Yojana, the scheme is projected to entail an investment of ₹75,000 crore.
    • Favorable Geography: India has abundant sunlight throughout the year, making it well-suited for solar power generation. About 5,000 trillion kWh per year of energy is incident over India’s land area with most parts receiving 4-7 kWh per sqm/day.
    • Increasing Energy Demand: India’s growing population and economy have led to a rising demand for energy. Electricity demand in India rose 7% in 2023 and is likely to average growth of 6% a year through 2026 on higher economic activity, according to the International Energy Agency.
    • International Collaboration: India has collaborated with various countries and international organizations to leverage expertise, technology transfer, and funding for solar projects. For example  International Solar Alliance (ISA).

    Way Forward:

    • Invest in High-Efficiency Panels: Choose solar panels with high-efficiency cells, such as monocrystalline photovoltaic cells, which can convert a greater percentage of sunlight into usable electricity
    • Use Energy Storage Solutions: Consider integrating energy storage systems, such as batteries, to store excess energy generated during the day and use it at night or during periods of low sunlight, thereby increasing the overall efficiency of the solar energy system.

    Mains PYQ: 

    Q Describe the benefits of deriving electric energy from sunlight in contrast to the conventional energy generation. What are the initiatives offered by our government for this purpose? (UPSC IAS/2020)

  • Unemployment Vs Wages

    Why in the news?

    Recently, there have been contentious talks regarding Pakistan’s unemployment being lower than India’s.

    According to Keynes, lower wage rate will lead to lower income of workers and thus to lower demand of goods. Lower demand will lower output that in turn will lower employment.

    Issues related to Unemployment vs Wages

    • Questioning on Data Accuracy and Interpretation: There is skepticism about the accuracy of unemployment data, particularly regarding the CMIE Consumer Pyramids Household survey. This raises questions about the basis of claims regarding unemployment rates and the subsequent policy responses.
    • Labor Force Participation: Concerns are raised about the significant withdrawal of individuals from India’s labor force, indicating potential issues with labor force participation rather than solely unemployment rates.
    • Youth Unemployment: The high youth unemployment rate of 45% is highlighted as a significant concern, suggesting challenges in integrating young people into the workforce and addressing their employment needs.
    • Informal Employment: The prevalence of informal employment, such as subsistence agriculture and informal wage employment, is noted as a structural issue in the labor market, potentially impacting wages and job quality.
    • Wage Levels: Despite low reported unemployment rates, there are concerns about the adequacy of wages, particularly for the poor. This raises questions about the quality of employment and the extent of underemployment or disguised unemployment.
    • Policy misalignment: Certain policy proposals, such as increasing public sector employment or implementing fiscal job guarantees, are critiqued for potentially misdiagnosing the problem and offering unsustainable solutions that may not address underlying wage issues.

    Steps taken by the Government: 

    • Pradhan Mantri Rojgar Protsahan Yojana (PMRPY): This scheme incentivizes employers to generate employment by having the government pay the entire 12% employer’s contribution to the Employees’ Provident Fund and Employees’ Pension Scheme for new employees for the first three years of their employment
    • Pradhan Mantri Mudra Yojana (PMMY): This scheme provides collateral-free loans up to ₹10 lakh to micro and small businesses and individuals to help them set up or expand their enterprises, thereby promoting self-employment.
    • Aatmanirbhar Bharat Package: This economic stimulus package, announced in response to the COVID-19 pandemic, includes various long-term schemes and policies aimed at making India self-reliant and creating employment opportunities.
    • Garib Kalyan Rojgar Abhiyaan: This 125-day campaign was launched to boost employment and livelihood opportunities for migrant workers and others affected in 116 districts across 6 states.
    • PM GatiShakti: This is a multi-modal connectivity plan that aims to create infrastructure and generate employment opportunities in sectors like roads, railways, airports, ports, and logistics.

    Way forward: 

    • Addressing Labor Force Participation: Implement policies aimed at increasing labor force participation, particularly among youth and marginalized groups, by creating more formal employment opportunities.
    • Improving Informal Employment Conditions: Develop strategies to formalize the informal sector by providing incentives for informal employers to register their businesses, improve working conditions, and ensure compliance with labor laws.
    • Enhancing Wage Levels: Take steps to improve wage levels, particularly for low-skilled workers engaged in subsistence agriculture, marginal self-employment, and informal wage employment.

    Mains PYQ:

    Q Besides the welfare schemes, India needs deft management of inflation and unemployment to serve the poor and the underprivileged sections of the society. Discuss.

  • Widal Test: Flaws of Typhoid Diagnosis  

    Why in the news?

    Patients with fever in India often undergo testing and treatment for typhoid fever, primarily relying on the Widal test.

    • The Widal test, though widely used, has several limitations that affect its accuracy and reliability.

    Typhoid diagnosis using Widal Test

    • The Widal test is used primarily to diagnose typhoid fever.
    • Typhoid fever, caused by Salmonella Typhi and related bacteria, presents with symptoms like high fever, stomach pain, weakness, and gastrointestinal issues.
    • It detects antibodies in the patient’s blood against the O (somatic) and H (flagellar) antigens of Salmonella Typhi.
    • Procedure:
    1. The presence of these antibodies is detected through an agglutination reaction.
    2. The test involves serial dilution of the patient’s serum.
    3. The highest dilution at which agglutination occurs indicates the antibody titer, with higher titers suggesting an active infection.

    Diagnostic Challenges:

    • The gold standard for diagnosing typhoid involves isolating the bacteria from blood or bone marrow cultures, which is time-consuming and resource-intensive.
    • Widal test is commonly used due to its convenience and accessibility. However, the Widal test’s interpretation is complicated by factors like the need for multiple serum samples, variations in cutoff values, and potential cross-reactivity with antibodies from other infections or vaccines.

    Challenges with Widal Test:

    • Impractical: A single positive Widal test does not confirm typhoid.
    • Complicated result interpretation: High background antibody levels and variability in test cutoff values.
    • Cross-reactivity with antibodies from other infections and false negatives due to prior antibiotic therapy undermine test reliability.

    Consequences of Widal Test Use:

    • Erroneous results obscure the true burden of typhoid in India, leading to inappropriate treatment and financial strain on patients.
    • Overuse of antibiotics based on Widal test results contributes to antimicrobial resistance, exacerbating the challenge of treating typhoid.

    PYQ:

    [2016] Which of the following statements is/are correct?

    Viruses can infect

    1. Bacteria

    2. Fungi

    3. Plants

  • CRISPR’s Breakthrough in Treating Blindness

    Why in the news?

    Scientists have successfully used CRISPR-Cas9 gene editing to restore vision in individuals with a rare form of inherited or congenital blindness.

    • The groundbreaking clinical trial, named “BRILLIANCE,” demonstrated promising results in improving vision and quality of life for participants with Leber congenital amaurosis (LCA), a severe vision disorder.

    What is Leber Congenital Amaurosis (LCA)?

    • LCA is a rare genetic disorder that primarily affects the retina the ‘light-sensitive’ tissue at the back of the eye. It leads to severe visual impairment or blindness at birth or within the first few months of life.
    • It is inherited in an autosomal recessive manner, meaning a child needs to inherit one defective gene from each parent to develop the condition.
    • There are several genes associated with LCA, with mutations in at least 14 different genes known to cause the disorder.
    • These genes generally affect the development and function of photoreceptors or the retinal pigment.

    Key highlights of the BRILLIANCE trial:

    • The BRILLIANCE trial involved 12 adults and two children diagnosed with LCA, a condition characterized by early-onset vision loss.
    • Participants received a single dose of a CRISPR gene therapy called EDIT-101, designed to correct mutations in the CEP290 gene responsible for LCA.
    • In this case, CRISPR-Cas9 cuts out the faulty DNA segment in the CEP290 gene and replaces it with a healthy DNA sequence, restoring the function of the CEP290 protein crucial for vision.
    • Out of 14 participants, 11 experienced improved vision without serious side effects.

    Back2Basics: CRISPR-Cas9 Gene Editing

    • CRISPR-Cas9 stands for Clustered Regularly Interspaced Short Palindromic Repeats and CRISPR-associated protein 9.
    • It is a technology that allows geneticists and researchers to edit parts of the genome by altering sections of the DNA sequence.
    • Emmanuelle Charpentier and Jennifer Doudna’s work on CRISPR-Cas9 as a ‘molecular scissor’ earned them the 2020 Nobel Prize in chemistry.
    • The system consists of two key components:
    1. Cas9: This is the enzyme that acts like a pair of molecular scissors. It is responsible for cutting the DNA strand at a specific location, allowing for the removal, addition, or alteration of DNA at that site.
    2. Guide RNA (gRNA): This is a piece of RNA that is designed to find and bind to a specific sequence of DNA that matches its code. The gRNA guides the Cas9 enzyme to the exact spot in the genome where an edit is desired.
    • Mechanism:
      • The process begins with the design of a gRNA that matches the DNA sequence where an edit is needed.
      • Once inside the cell, the Cas9 enzyme and the gRNA form a complex that can identify and bind to the target DNA sequence.
      • The Cas9 then cuts the DNA at this location.
      • After the DNA is cut, the cell’s natural repair mechanisms can be harnessed to add or remove genetic material, or to make specific changes to the DNA.

     

    PYQ:

    [2019] What is Cas9 Protein that is often mentioned in news?

    (a) A molecular scissors used in targeted gene editing

    (b) A biosensor used in the accurate detection of pathogens in patients

    (c) A gene that makes plants pest-resistant

    (d) A herbicidal substance synthesized in genetically modified crops

    • This behavior, documented in a recent study published in Scientific Reports, represents a novel instance of self-medication among wild animals.

    About Orangutans

    • Orangutans, are distinguished by their vivid red fur, are the largest arboreal mammals and spend the majority of their time in trees and forests.
    • The name “orangutan” translates to “man of the forest” in Malay.
    • They possess long, powerful arms and grasping hands and feet that facilitate movement through the branches.
    • Highly intelligent, these great apes share 96.4% of genetic makeup of modern man.
    • Orangutans primarily inhabit the tropical rainforests of Southeast Asia, specifically on the islands of Borneo and Sumatra.
    • Conservation Status: Critically Endangered (IUCN Red list)
    • Population: Bornean (Approximately 104,700); Sumatran (Approximately 13,846); Tapanuli (Around 800);
    • Behavioral Features:

  • An Inheritance Tax will help reduce Inequality

    Why in the news? 

    A remark by Chairman of Indian Overseas Congress Sam Pitroda on implementing an inheritance tax as a tool of wealth redistribution has sparked massive debates.

    The Negative Impact of Inequality:

    • Growth affected: Inequality harms growth in the medium-to-long run by reducing firm productivity, lowering labor income, and diverting resources away from essential rights like education.
    • Inequal Opportunity: In unequal countries like India, where one is born greatly influences lifetime outcomes, with almost a third of consumption variation being explained by the place of residence (state, city, or village).
    • Concentration of Wealth: The richest 1% holding 40% of India’s wealth underscores the vast wealth disparities that exacerbate inequality.
    • Skewed Distribution of Gains: Research indicates that the gains from India’s growth over the last two decades have disproportionately benefited high-income urban residents, further exacerbating inequality.

    What is Inheritance Tax? 

    • An inheritance tax is a tax levied on the assets or wealth passed down from one generation to another upon the death of the owner.
    • Unlike a wealth tax, which is recurring and applied to all physical and financial assets an individual owns, an inheritance tax is a one-time tax specifically targeting intergenerational transfers of wealth.

     

    How an Inheritance Tax could help reduce Inequality?

    The Constitution mandates equality of status and opportunity, obliging the government to take steps to reduce disparities arising from accidents of birth.

    • Reduction of Wealth Concentration: By taxing large inheritances, an inheritance tax helps to redistribute wealth from the wealthiest individuals and families to the broader society.
    • Encouragement of Productive Investments: Inheritance taxes can encourage wealthy individuals to invest their wealth in productive activities rather than simply passing it down to heirs.
    • Incentive for Innovation: Critics may argue that inheritance taxes disincentivize innovation by reducing the incentive to accumulate wealth to pass on to future generations.
    • Funding for Public Expenditure: Revenue generated from inheritance taxes can be used to fund essential public services and social programs, such as education, healthcare, infrastructure, and poverty alleviation initiatives.
    • Historical Effectiveness: Historical examples, such as the estate duty in India between 1953 and 1985. It reduced the top 1% personal wealth share from 16% to 6% between 1966 and 1985.
    Another approach is the Land Value Tax (LVT): The Land Value Tax (LVT) is a tax system that levies charges on the unimproved value of land. Unlike traditional property taxes, which take into account both the value of the land and the value of any buildings or improvements on the land, the LVT focuses solely on the value of the land itself.

     

    Conclusion: Tackling wealth inequality requires a multifaceted approach that includes measures such as inheritance taxation, wealth taxation, and the Land Value Tax (LVT). These measures not only help to redistribute wealth and promote economic fairness but also contribute to fostering a more inclusive and prosperous society where opportunities are more evenly distributed.

  • CBDC pilot programmes for CPs, CDs likely: RBI

    Why in the news?

    RBI Governor Shaktikanta Das unveiled plans for a pilot program targeting the wholesale segment of Central Bank Digital Currency (CBDC) focusing on commercial papers (CPs) and certificates of deposits (CDs).

    What is Central Bank Digital Currency (CBDC)?

    • CBDC is a legal tender to be issued by the central bank in digital form; like rupee notes or coins, which are in physical form.
    • It was announced in the Union Budget 2022-23.
    • Subsequently, the Government amended Section 22 of the RBI Act, 1934 through the Finance Bill 2022. [Ref].
    • Working of CBDC:
      • Like fiat currency, it can also be exchanged between people. Simply, put it’s just like rupee (₹) notes but in digital form (e₹). 
      • However, unlike fiat currency that’s usually stored in banks and hence their liability, CBDC is a liability on the RBI’s balance sheet.
      • That’s why one does not necessarily need to have a bank account to own a digital rupee.

  • Magnetic Resonance Imaging (MRI) and the Science behind

    Why in the news?

    • Magnetic Resonance Imaging (MRI) revolutionized medical diagnostics, offering non-invasive insights into soft tissues.
    • The pioneering efforts of Paul Lauterbur and Peter Mansfield led to its commercialization, earning them the Nobel Prize in Medicine in 2003.

    What is MRI?

    • Magnetic resonance imaging (MRI) is a non-invasive diagnostic procedure used to obtain detailed images of soft tissues within the body.
    • It is particularly valuable for imaging sophisticated structures like the brain, cardiovascular system, spinal cord, joints, muscles, liver, and arteries.
    • MRI is instrumental in diagnosing and monitoring various conditions, including cancer, neurological disorders (such as Alzheimer’s and stroke), and cardiovascular diseases.
    • Functional MRI (fMRI) can also assess brain activity by monitoring changes in blood flow.

    Working Principle:

    • MRI utilizes the magnetic properties of hydrogen atoms (one proton with one electron around it), which are abundant in water and fat molecules found throughout the body.
    • The MRI machine generates a powerful magnetic field, aligning hydrogen atoms within the body.
    • Radiofrequency pulses are then applied, causing hydrogen atoms to absorb energy and emit signals.
    • These emitted signals are detected by sensors and processed by a computer to create detailed images of the body’s internal structures.

    Components of an MRI Machine:

    The MRI machine consists:

    • Superconducting Magnet: Large magnet (superconducting magnet) that produces a powerful and stable magnetic field.
    • Gradient Coils: Gradient magnets produce smaller magnetic fields with varying strengths and directions, allowing for precise imaging of specific body areas.
    • Radiofrequency Coils: This emit radiofrequency pulses to excite hydrogen atoms in the body. The frequency of pulse the ‘excess’ atoms have to absorb is called the Larmor frequency.
    • Detectors: It capture emitted signals from hydrogen atoms and convert them into image data for analysis.

    Advantages of MRI:

    • High-Resolution Imaging: MRI offers high-resolution imaging with excellent tissue contrast, allowing for accurate diagnosis and treatment planning.
    • Versatile Viewing Angles: It can visualize structures from various angles without the need for repositioning, providing comprehensive information.
    • Safety and Non-Invasiveness: MRI scans are non-invasive and do not involve ionizing radiation, making them safe for repeated use.
    • Enhanced Image Quality: Contrast agents can enhance image quality by highlighting specific tissues or abnormalities.

    Limitations of MRI:

    • High Costs: MRI machines are expensive to purchase and maintain, resulting in high healthcare costs for patients.
    • Requirement for Patient Stillness: Patients undergoing MRI scans must remain still for extended periods to prevent image distortion, which can be challenging for some individuals.
    • Discomfort or Anxiety: The strong magnetic fields and loud noises produced during MRI scans may cause discomfort or anxiety for patients.
    • Limitations with Metallic Implants: Certain metallic implants or objects can interfere with MRI scans, limiting their use in individuals with such implants.
