  • Trade Protectionism in India

    Context

    India’s efforts for deepening India’s trade ties with several countries could be scuttled by rising trade protectionism at home.

    Increasing protectionism by India

    • Increase in average tariffs: As Arvind Panagariya has argued, the simple average of India’s tariffs that stood at 8.9 per cent in 2010-11 has increased by almost 25 per cent to 11.1 per cent in 2020-21.
    • These increases in tariff rates have reversed the political consensus on tariff liberalisation that India followed since 1991.
    • Initiator of anti-dumping measures: India is the highest initiator of anti-dumping measures aimed at shielding domestic industry from import competition.
    • According to the WTO, from 2015 to 2019, India initiated 233 anti-dumping investigations, which is a sharp increase from 82 initiations between 2011 and 2014 (June).
    • The anti-dumping initiations by India from 1995 (when the WTO was established) till 2020 stand at 1,071.
    • Expanding the scope of Article 11(2)(f): India recently amended Section 11(2)(f) of the Customs Act of 1962, giving the government the power to ban the import or export of any good (not just gold and silver, as this provision applied earlier) if it is necessary to prevent injury to the economy. 
    • Expanding the scope of Article 11(2)(f) to cover any good is inconsistent with India’s WTO obligations.
    • WTO allows countries to impose restrictions on imports in case of injury to domestic industry, not to the “economy”.
    • Restrictive rules of origin: Finance Minister in her budget speech of 2020 said that undue claims of FTA benefits pose a threat to the domestic industry.
    •  Subsequently, India amended the rules of origin requirement under the Customs Act.
    • Rules of origin determine the national source of a product.
    • This helps in deciding whether to apply a preferential tariff rate (if the product originates from India’s FTA partner country) or to apply the most favoured nation rate (if the product originates from a non-FTA country).
    • But India has imposed onerous burdens on importers to ensure compliance with the rules of origin requirement.
    • The intent appears to be to dissuade importers from importing goods from India’s FTA partners.
    • Impact of vocal for local: The clarion call given by Prime Minister Narendra Modi to be “vocal for local” is creating an ecosystem where imports are looked at with disdain, upsetting competitive opportunities and trading partners.

    What are the implications?

    • Protectionist steps are justified on the ground that they would help domestic companies grow into viable competitors.
    • But the fact is that protectionism does not benefit the domestic economy.
    • It rather encourages inefficiency of domestic manufacturers.
    • It is likely to hurt exports, make domestic goods costlier and reduce benefits to consumers from increased competition.
    • So in the long term, protectionism is likely to have only a negative effect on industry’s ability to compete globally.
    • For India to reap the benefits of the summits and partnerships like Quad, there needs to be a fundamental shift in policy.
    • Amore pragmatic approach in line with the recent initiatives to reverse the retrospective tax legislation and provide support to the flailing telecom sector must be expanded.

    Conclusion

    India can’t maximise its interests at the expense of others. Its experiment with trade protectionism in the decades before 1991 was disastrous. We should recall Winston Churchill’s warning: “Those who fail to learn from history are condemned to repeat it.”

  • Need for Strategic Reserves of Coal and Gas

    The Centre has stressed the need to build strategic reserves of imported coal and gas as was being done for petroleum products.

    Why need strategic reserves for Coal and Gas?

    • Many countries have started keeping strategic reserves, because when it comes to a crunch, every country will meet its needs first.
    • Russia has curtailed gas supply to Europe because they want more gas to be consumed within their country.
    • There is a surge in power demand combined with a fall in imports due to high global coal prices have led to supply disruptions.

    Do you know?

    In 1998, the AB Vajpayee administration proposed building petroleum reserves as a long-term solution to managing the oil market.

    What are Strategic Reserves?

    • Indian refiners maintain 64.5 days of crude storage, so India has overall reserve oil storage of 74 days
    • Indian Strategic Petroleum Reserves Limited (ISPRL) is an Indian company responsible for maintaining the country’s strategic petroleum reserves.
    • ISPRL is a wholly-owned subsidiary of the Oil Industry Development Board (OIDB), which functions under the administrative control of the Ministry of Petroleum and Natural Gas.
    • It maintains an emergency fuel store of total 5.870 million cubic meters of strategic crude oil enough to provide 9.5 days of consumption.

    SPRs in India

    S. No. Location Capacity
    1 Visakhapatnam, Andhra Pradesh 1.33 million tonnes
    2 Mangalore, Karnataka 1.5 million tonnes
    3 Padur, Karnataka 2.5 million tonnes and an additional 2.5 million tonnes under construction
    4 Chandikhol, Odisha 4 million tonnes (under construction)

     

    Why were SPRs created?

    • Gulf War, 1990: It caused a sharp rise in oil prices and a massive increase to India’s imports.
    • Forex fluctuations: During the subsequent 1991 Indian economic crisis, foreign exchange reserves could barely finance three weeks’ worth of imports while the government came close to defaulting on its financial obligations.
    • Price volatility: India was able to resolve the crisis through policies that liberalized the economy. However, India continued to be impacted by the volatility of oil prices.

    How are they constructed?

    • The crude oil storages are constructed in underground rock caverns and are located on the East and West coasts of India.
    • Crude oil from these caverns can be supplied to the Indian Refineries either through pipelines or through a combination of pipelines and coastal movement.
    • Underground rock caverns are considered the safest means of storing hydrocarbons.

  • What are Non-Transgenic Gene Editing techniques?

    The Centre is yet to decide on a research proposal from scientists which would allow plants to be genetically modified without the need for conventional transgenic technology.

    What is Genome Editing?

    • Genome editing (also called gene editing) is a group of technologies that give scientists the ability to change an organism’s DNA.
    • These technologies allow genetic material to be added, removed, or altered at particular locations in the genome.
    • Several approaches to genome editing have been developed.

    Techs for Genome Editing

    The core technologies now most commonly used to facilitate genome editing are

    1. Clustered regularly interspaced short palindromic repeats (CRISPR)- associated protein 9 (Cas9)
    2. Transcription activator-like effector nucleases (TALENs)
    3. Zinc-finger nucleases (ZFNs)
    4. Homing endonucleases or meganucleases

    Newer technologies

    • The Institute has now moved to newer technologies such as Site-Directed Nuclease (SDN) 1 and 2.
    • They aim to bring precision and efficiency into the breeding process using gene-editing tools such as CRISPR, whose developers won the Nobel Prize for Chemistry in 2020.

    About CRISPR

    • CRISPR-Cas9 was adapted from a naturally occurring genome editing system in bacteria.
    • The bacteria capture snippets of DNA from invading viruses and use them to create DNA segments known as CRISPR arrays.
    • The CRISPR arrays allow the bacteria to “remember” the viruses (or closely related ones).
    • If the viruses attack again, the bacteria produce RNA segments from the CRISPR arrays to target the viruses’ DNA.
    • The bacteria then use Cas9 or a similar enzyme to cut the virus DNA apart, which disables the virus.
    • This method is faster, cheaper, more accurate, and more efficient than other existing genome editing methods.

    What is Non-Transgenic Gene Editing?

    • Unlike the older GM technology which involves the introduction of foreign DNA, the new proposal involves the use of gene editing tools to directly tweak the plant’s own genes instead.
    • It does not involve inserting any foreign DNA.

    Use in India

    • Scientists at the Indian Agricultural Research Institute (IARI) are in the process of developing resilient and high-yield rice varieties using such gene editing techniques.
    • However, this proposal has been pending with the Genetic Engineering Appraisal Committee (GEAC) for almost two years.

    Why need such technique?

    • Similar to natural mutation: But in this case, this protein is right there in the plant, and is being changed a little bit, just as nature does through mutation.
    • Faster and cheaper: It is much faster and far more precise than natural mutation or conventional breeding methods which involve trial and error and multiple breeding cycles.
    • Safe for consumption: When a protein comes from an outside organism, then you need to test for safety.
    • Pathbreaking: It is potentially a new Green Revolution.

    No approval issues

    • The SDN 1 and SDN 2 categories of genome-edited plants do not contain any foreign DNA when they are taken to the open field trials.
    • The US, Canada, Australia and Japan are among the countries which have already approved the SDN 1 and 2 technologies as not akin to GM.
    • So, such varieties of rice can be exported without any problem.
    • The European Food Safety Authority has also submitted its opinion that these technologies do not need the same level of safety assessment as conventional GM.

  • Pakistan, Turkey on FATF greylist

    The Financial Action Task Force (FATF) kept Pakistan on the grey list yet again since 2018. The FATF also announced the ‘greylisting’ of Jordan, Mali and Turkey.

    What is the FATF?

    • FATF is an intergovernmental organization founded in 1989 on the initiative of the G7 to develop policies to combat money laundering.
    • The FATF Secretariat is housed at the OECD headquarters in Paris.
    • It holds three Plenary meetings in the course of each of its 12-month rotating presidencies.
    • As of 2019, FATF consisted of 37 member jurisdictions.

    India and FATF

    • India became an Observer at FATF in 2006. Since then, it had been working towards full-fledged membership.
    • On June 25, 2010, India was taken in as the 34th country member of FATF.
    • The EAG (Eurasian Group) is a regional body comprising nine countries: India, Russia, China, Kazakhstan, Kyrgyzstan, Tajikistan, Turkmenistan, Uzbekistan and Belarus.

    What is the role of FATF?

    • Watchdog on terror financing: The rise of the global economy and international trade has given rise to financial crimes such as money laundering.
    • Recommendation against financial crimes: The FATF makes recommendations for combating financial crime, reviews members’ policies and procedures, and seeks to increase acceptance of anti-money laundering regulations across the globe.

    What is the Black List and the Grey List?

    • Black List: The blacklist, now called the “Call for action” was the common shorthand description for the FATF list of “Non-Cooperative Countries or Territories” (NCCTs).
    • Grey List: Countries that are considered safe haven for supporting terror funding and money laundering are put in the FATF grey list. This inclusion serves as a warning to the country that it may enter the blacklist.

    Consequences of being in the FATF grey list:

    • Economic sanctions from IMF, World Bank, ADB
    • Problem in getting loans from IMF, World Bank, ADB and other countries
    • Trade sanctions: Reduction in international trade
    • International boycott

    Pakistan and FATF

     

    • Pakistan, which continues to remain on the “grey list” of FATF, had earlier been given the deadline till June to ensure compliance with the 27-point action plan against terror funding networks.
    • It has been under the FATF’s scanner since June 2018, when it was put on the Grey List for terror financing and money laundering risks.
    • FATF and its partners such as the Asia Pacific Group (APG) are reviewing Pakistan’s processes, systems, and weaknesses on the basis of a standard matrix for anti-money laundering (AML) and combating the financing of terrorism (CFT) regime.

  • Extending BSF’s powers won’t resolve policing problems, security threats

    Context

    The Union home ministry’s order to extend the jurisdiction of the Border Security Forces (BSF) has caused furore.

    Justification for the order

    • Increased threats: The Taliban’s takeover in Afghanistan has revived serious threats of cross-border infiltration from Pakistan, while China, our other tense neighbour, has been increasingly aggressive over the past year.
    • Change in the jurisdiction: The BSF’s powers have not altered, only its jurisdiction has changed from 15 to 50 kilometres and that is for the purposes of uniformity.

    Issues raised by the order

    • Lack of clarity: That India is facing heightened security threats is undeniable.
    • What is unclear is how the BSF’s extended jurisdiction helps counter these threats.
    • The recent drug seizures in Gujarat’s Adani port were successfully conducted by the customs department and the Directorate of Revenue Intelligence — not by the BSF, despite their jurisdiction depth of 80 kilometres in the state.
    • No need for uniformity: In the security context, arguments about uniformity are patently absurd.
    • There is no uniformity between coastal smuggling in Gujarat, cross-border infiltration in Jammu and Kashmir, smuggling and drone drops in Punjab.
    • Risk of civilian resentment: The order raises the risk of civilian resentment, even clashes, given that the BSF is not trained to operate in residential and/or market areas, it will also undermine the state police forces’ morale even further.
    • Overstretching BSF: The BSF is likely to be overstretched by its new tasks.
    • Once again, that could weaken rather than strengthen the BSF’s security capabilities.

    Tackling illegal migration

    • Curbing illegal migration requires coordinated action between India and its neighbours, first at the political and then at the security level.
    • The administration’s migration policies — the Citizenship Amendment Act, deporting Myanmar refugees even when they were locally welcomed, cancelling Afghan visas have made cooperation more difficult and impacting negatively on border security.
    • To think that the BSF can plug what is a government-to-government policy gap is prone to failure.

    Way forward

    • Coordination: The underlying issue when it comes to tackling both smuggling and infiltration threats is coordination between our security agencies.
    • Police reform: The state police forces have weakened, therefore, the solution lies in putting police reforms on an emergency footing, not in extending the BSF’s jurisdiction.
    • That we have a grave policing problem across India is undeniable.
    • But the answer is not to write them off; it is to insulate them from political misuse while holding them accountable for rule of law lapses.
    • Moreover, to strengthen police capabilities it is vital that other security forces cooperate with local police forces, not bypass them.
    • The BSF has had a relatively good record of local police cooperation thus far.
    • When it comes to cross-border infiltration, intelligence is the key.

    Conclusion

    Strengthening police capabilities, improving coordination between security agencies and cooperation with state law enforcement are needed to address these issues.

  • Punjab farmers create Bio-Enzymes from Kinnow

    Some farmers in Punjab, especially in the Kinnow belt, have started making Bio-Enzymes (BEs) from this waste fruit — peel and ‘D’ grade, very small kinnows.

    What is a Kinnow?

    • The ‘Kinnow’ is a high yield citrus fruit cultivated extensively in the wider Punjab region of India and Pakistan.
    • It is a year-long duration crop and the main harvesting period is from November-end to March.
    • It looks similar to orange but is smaller in size.

    Agricultural significance of Kinnows

    • Fallen fruit is a major challenge for kinnow farmers in the state as one needs to dig up small pits to bury them, otherwise the fallen fruit rot and invite a fly attack on the healthy fruit still on the plants.
    • But now, some farmers are using this waste kinnow to improve the pH level and soil fertility of their land by making BEs from this waste fruit.

    What are Bio-Enzymes?

    • Chemically, the Bio Enzymes are a mixture of complex organic substances such as proteins, salts and other materials that are by-products of the bacteria/yeast.
    • They produced through fermentation of organic waste including various fruits, vegetable peels and flowers, by mixing in sugar, jaggery/molasses and water.
    • BE’s also have a lot of usage in our daily lives. They can be used as natural cleansers.

    Benefits offered by BEs

    • BEs have a lot of good microbes and one of the major methods which helps overall improvement of our ecology.
    • It helps in mitigating the imbalance occurred due to overuse of chemicals, in our soil, air and water.
    • In a state like Punjab where water table is depleting fast and water contamination is also major issue, BEs can bring the soil back to life.
    • It helps in better water recharging and also stops the contamination of water by improving the health of soil.

  • What is the Lucy Mission?

    The NASA has launched Lucy, the spacecraft on a 12-year cruise to look back into the origins of the solar system through Trojans.

    Lucy Mission

    • Lucy will fly by eight Jupiter asteroids—seven Trojans and one main-belt asteroid — over the next 12 years.
    • It is NASA’s first single spacecraft mission in history to explore so many different asteroids.
    • Lucy will run on solar power out to 850 million kilometers away from the Sun.
    • This makes it the farthest-flung solar powered spacecraft ever, according to NASA.

    What is Jupiter Trojan Asteroids?

    • Simply known as Trojans, they are a large group of asteroids that share Jupiter’s orbit around the Sun.
    • Thousands of such asteroids exist in a gravitationally stable space.
    • The swarms lead and follow the planet Jupiter along its orbit around the Sun.

    What exactly are Trojans?

    • Lucy’s Trojan destinations are trapped near Jupiter’s Lagrange (L) points, which are gravitationally stable locations — it is where the gravity from the Sun and from Jupiter cancel each other out.
    • This means their orbits are stable and the Trojans are trapped in the space between.
    • This also means that asteroids are as far away from Jupiter as they are from the Sun.
    • Jupiter’s leading and trailing Lagrangian points (L4 and L5) have been stable over the age of the solar system.
    • This means that their orbits have accumulated many, many asteroids.
    • It makes sense to call a Trojan a co-orbital object, which moves around one of the two stable Lagrangian points.

    When and how were they discovered?

    • It took many a scientist to understand Trojans, and subsequently, name them so.
    • A German astro-photographer in 1906 made an important discovery: An asteroid with a particularly unusual orbit. As Jupiter moved, this asteroid remained ahead of Jupiter.
    • It was observed that the asteroid was nearly 60 degrees in front of Jupiter.

    Students with engineering background would better understand who Lagrange was. Rest need not care.

    Lagrange’s propositions

    • This specific position of a peculiar behaviour was predicted by the Italian-French mathematician Joseph-Louis Lagrange over 100 years earlier.
    • Lagrange had argued that if a small celestial body is placed at one of two stable points in a planet’s orbit around the Sun (the L4 and L5), the asteroid would remain stationary from the planet’s perspective.
    • This is due to the combined gravitational forces of the planet and the Sun.
    • Thus, Lagrange’s prediction acquired credibility. More such asteroids were discovered over subsequent months in Jupiter’s Lagrange point L5.

    Behind the name: Lucy

    • It is the fossil of a hominin that lived 3.2 million years ago.
    • She is known to be one of the most famous pre-human fossil in history.
    • Nearly 40 per cent of the fossilised skeleton of this hominin was discovered in 1974 by a team of paleoanthropologists led by Donald Johanson.
    • The name was inspired from the famous Beatles song “Lucy in the Sky With Diamonds,” which Johanson’s team listened to at camp the night of their discovery.

    Back2Basics: Lagrange Points

    • Lagrange points are positions in space where objects sent there tend to stay put.
    • They are named after Italian-French mathematician Josephy-Louis Lagrange.
    • At Lagrange points, the gravitational pull of two large masses precisely equals the centripetal force required for a small object to move with them.
    • These points in space can be used by spacecraft to reduce the fuel consumption needed to remain in position.
    • There are five special points where a small mass can orbit in a constant pattern with two larger masses.

     

  • Places in news: Mawsmai Cave

    A micro snail species named Georissa mawsmaiensis has recently been discovered from Mawsmai, a limestone cave in Meghalaya, 170 years after the last such discovery was made.

    Georissa mawsmaiensis

    • Georissa is found in soil or subterranean habitats in lowland tropical forest as well as high altitude evergreen forests or on rock surfaces rich in calcium.
    • The members of the Georissa genus are widely distributed across and reported from Africa, Asia, and the Pacific.
    • However, they are confined to microhabitats consisting of limestone caves or karst landscapes formed by the dissolution of limestone.

    About Mawsmai Cave

    • The Mawsmai cave is situated in the small village of Mawsmai, around four kilometres from Cherrapunjee (Sohra) in the East Khasi Hills district of Meghalaya.
    • It is located at an altitude of 1,195 metres above sea level and is indirectly influenced by the streams of the Kynshi river originating from the East Khasi Hills.
    • The term ‘Mawsmai’ means ‘Oath Stone’ in the Khasi language. The Khasi people use the local term ‘Krem’ for the cave.
    • It is famous for its fossils, some which can be spotted looking at the walls and formations inside.
    • The longest is Krem Liat Prah in the Jaintia Hills, which is 30,957 m (31 km approx.)

  • The outlines of a national security policy

    Context

    National security concepts have, in the two decades of the 21st century, undergone fundamental changes. Cyberwarfare has vastly reduced the deterrent value of conventional deterrents.

    Emergence of cyberwarfare

    • In the 21st century, after cybertechnology enters as an important variable in nations’ defence policies.
    • Geographical land size or GDP size will be irrelevant in war-making capacity or deterrence.
    • These fundamental changes are entirely due to the earlier 20th century innovations in cybertechnology and software developments.
    • Drones, robots, satellites and advanced computers as weapons are already in use.
    • Some examples of further innovations are artificial intelligence and nanotechnology.
    • Tracking those cyber warfare threat will need a new national security policy.
    • By credible accounts, China, recently, publicly cautioned Indians to sit up and take notice by using cybertechnology to shut down Mumbai’s electric supply in populated areas of the city, for a few hours.

    Four dimensions of national security policy

    • Objectives: the objective of the National Security Policy in the 21st century is to define what assets are required to be defended, the identity of opponents.
    • Although the novel coronavirus is perhaps accidental, it has completely destabilised peoples globally and their governments in all nations of the world over.
    • This is a preview of the kinds of threats that await us in the coming decades which a national security policy will have to address by choosing a nation’s priorities.
    • Priorities: National security priorities will require new departments for supporting several frontiers of innovation and technologies such as hydrogen fuel cells, desalination of seawater, thorium for nuclear technology, anti-computer viruses, and new immunity-creating medicines.
    • This focus on a new priority will require compulsory science and mathematics education, especially in applications for analytical subjects.
    • Strategy: The strategy required for this new national security policy will be to anticipate our enemies in many dimensions and by demonstrative but limited pre-emptive strikes by developing a strategy of deterrence of the enemy.
    • For India, it will be the China cyber capability factor which is the new threat for which it has to devise a new strategy.
    • Resource mobilisation: The macroeconomics of resource mobilisation depends on whether a nation has ‘demand’ as an economic deficit or not.
    • If demand for a commodity or service is in deficit to clear the market of the available supply of the same, then liberal printing of currency and placing it in the hands of consumers is recommended for the economy to recover the demand-supply parity.
    • A way to increase demand is by lowering the interest rate on bank loans or raising the rates in fixed deposits which will enable banks to obtain liquidity and lend liberally for enhancing investment for production.
    • If it is ‘supply’ that is short or in deficit compared to demand, then special measures are required to incentivise to encourage an increase in supply.

    Conclusion

    National security at its root in the 21st century will depend on mind-boggling skills in the four dimensions mentioned above.

  • Type Of Technologies in Solar Panels

    Context

    Large-scale solar projects in Tamil Nadu have seen rapid growth in recent years. By embracing advances in solar technologies, India can continue to lead in this sector.

    Factors driving growth

    • In the past five years, the cumulative installed capacity witnessed a four-fold increase in Tamil Nadu to 4.4 GW, as of March 2021.
    • High insolation level: Aiding this capacity addition is the State’s reasonably high insolation levels and matching solar potential, estimated at 279GW.
    • Decline in price: The sharp decline in the prices for solar and resulting cost competitiveness is another factor.
    • National target: Additionally, in response to the ambitious national targets and to spur sector specific development, Tamil Nadu released the Solar Policy of 2019, aiming for 9GW of solar installations by 2023.

    Type of technology use for solar panel

    • 1) Mono-crystalline Vs multi-crystalline panels: ‘First-generation’ solar cells use mono-crystalline and multi-crystalline silicon wafers.
    • The efficiency of mono-crystalline panels is about 24%, while for multi-crystalline panels it is about 20%.
    • Mono-crystalline cells are dominant today.
    • Although mono-crystalline panels are priced higher than multi-crystalline ones, the difference is diminishing and will soon attain parity.
    • This would result in mono panels being preferred over multi due to their higher efficiency, greater energy yield and lower cost of energy.
    • 2) Bifacial solar cells: Newer technologies incorporating crystalline silicon focus on bifacial solar cells, capable of harvesting energy from both sides of the panel.
    • Bifacials can augment the power output by 10-20%.
    • Within this, the Passive Emitter and Rear Contact technology is predicted to gain popularity. However, it is yet to achieve price parity for large-scale deployment.
    • 3) Thin-film technologies: It is classified as the ‘second generation of solar PVs.
    • In addition to being used in solar farms and rooftops, thin films with their low thickness, light weight and flexibility are also placed on electronic devices and vehicles, power streetlights and traffic signals.
    • Mainstream thin films utilise semiconductor chemistries like Cadmium Telluride with module efficiencies of around 19%.
    • Other technologies include Amorphous Silicon and Copper Indium Gallium Di-Selenide.
    • Nanocrystal and dye-sensitised solar cells are variants of the thin film technology. These are in early stages for large-scale commercial deployment
    • However, the efficiency of thin films is lower than that of crystalline silicon.
    • 4) Perovskite: These are grouped as ‘third generation’ and contain technologies such as perovskite, nanocrystal and dye-sensitised solar cells.
    • Perovskites have seen rapid advances in recent years, achieving cell efficiency of 18%.
    • They have the highest potential to replace silicon and disrupt the solar PV market, due to factors such as ease of manufacture, low production costs and potential for higher efficiencies.
    • 5) Use of Graphene Quantum-dots: Graphene is made of a single layer of carbon atoms bonded together as hexagons.
    • Solar cells made of graphene are of interest due to high theoretical efficiency of 60% and its super capacitating nature.
    •  Quantum-dot PVs use semiconductor nanocrystals exhibiting quantum mechanical properties capable of high efficiency of about 66%.
    • However, both these are in the early stages of research.

    Technologies to better integrate solar PVs into the grid

    • These technologies include weather forecasting and power output prediction systems; operation monitoring and control systems; and scheduling and optimisation systems.
    • Additionally, automatic systems have been developed for the smooth resolution of output fluctuations.

    Way forward

    • A portion of the budget for renewable energy targets should be set aside exclusively for new technologies.
    • Grants and subsidies can also be provided for their adoption.
    • Efforts must be taken to address gaps in research, development, and manufacturing capabilities in the solar sector through sector-specific investment and incentives.
    • There must also be greater industry-academia collaborations and funding opportunities for startups.
    • A comprehensive sector-specific skilling programme is also required for workers.

    Conclusion

    All these efforts would help the country become a global player in the solar power sector.
