Renewable energy target now 227 GW

  • India is one of the countries with the largest production of energy from renewable sources. In the electricity sector, renewable energy account for 34.6% of the total installed power capacity. Large hydro installed capacity was 45.399 GW as of 30 June 2019, contributing to 13% of the total power capacity. The remaining renewable energy sources accounted for 22% of the total installed power capacity (81. 3107 GW) as of 31 July 2019.
  • In 2015 Union government has announced 175 GW of renewable energy installations; recently the target has been increased to 225 GW.
  • When India hits the 175 GW target, it stands to meet its greenhouse-gas emission goal under the Paris climate agreement. Of the current goal of 100 GW from solar energy by 2022, 40 GW is to come from rooftop installations, and 60 GW from large solar parks.
  • India will add 227 GW of renewable energy capacity by March 2022, possibly scaling up its ranking to the top three countries making investments in the sector.


National Nutrition Mission

  • The NNM, as an apex body under Ministry of Women and Child Development will monitor, supervise, fix targets and guide nutrition related interventions across the Ministries. It will monitor various schemes contributing towards addressing malnutrition.
  • The programme through the targets will strive to reduce the level of stunting, under-nutrition, anaemia and low birth weight babies. It will create synergy, ensure better monitoring, issue alerts for timely action, and encourage States/UTs to perform, guide and supervise the line Ministries and States/UTs to achieve the targeted goals.


  • The mission, commencing 2017-18, has a target to reduce under-nutrition and low birth-weight by 2 per cent each year.
    • It will strive to achieve reduction in stunting from 38.4 per cent as per the National Family Health Survey-4 to 25 per cent by 2022.
    • It also aims to bring down anaemia among young children, women and adolescent girls by three per cent per year.
    • Under NNM, the ministries of women and child development, health and family welfare, and water and sanitation will work together.
    • The mission will form an apex body that would fix targets and monitor, supervise and guide nutrition-related interventions across the ministries.
    • The mission would include several components like an ICT (information and communications technology)-based real-time monitoring system, incentivizing of states and Union territories to meet their targets, social audits, and setting up of nutrition resource centres.
    • Anganwadi workers will also be offered incentives for using IT-based tools such as smart phones.
    • Aadhaar card is a mandatory requirement to avail the benefits of the mission.


Survey of dragonflies hints at impact of floods

  • A survey of dragonflies and damselflies held in the Silent Valley National Park (SVNP) has discovered eight new species, but reported an alarming decrease in the odonate population, raising concerns over the ecological impact of the successive floods in the State.
  • The three-day survey, conducted last week jointly by the Silent Valley National Park and the Society for Odonate Studies, showed that several dragonfly species, including the Global Wanderer (Pantala flavescens), were missing from the national park.
  • However, eight new odonate species were found in the survey held in 11 camps across the buffer and core areas of the national park.
  • Odonates were great biological indicators and studies on them would provide crucial information on the health of aquatic habitats and variations occurring in the climate. Odonates are good pest controllers, too.

Silent Valley National Park

  • Silent Valley Park in Kerala will soon reopen to visitors. It is located in the Northeast corner of Palakkad district.
  • It is a beautiful representation of the last remaining rain forest of Kerala. Silent Valley was declared as National Park in 1984 and formally inaugurated in the year 1985.
  • It constitutes the centrepiece of the Nilgiri Biosphere Reserve, an integral part of the Western Ghats. It was called ‘Sairandhrivanam’ as it was considered this was where Sairandhiri (the secret identity donned by Panchali, from the epic Mahabharata) hid along with her five husbands
  • A perennial river named Kunthipuzha is passing through the western side of the park, from north to south direction finally merging in to Bharathapuzha.
  • The endangered lion tailed macaque is found in this park.
  • The indigenous tribal groups that live within park boundaries include Irulas, Kurumbas, Mudugas and Kattunaikkars.



  • Biomining is the process of using microorganisms (microbes) to extract metals of economic interest from rock ores or mine waste. Biomining techniques may also be used to clean up sites that have been polluted with metals.
  • Biomining is use of organisms to promote the LEACHING (solubilization) of metals from their ores or use of organisms, such as BACTERIA and PLANTS, to accumulate metals from mine tailings. The metals can then be recovered from the cells of the organism. Biomining also allows us to recycle resources by extracting useful components from the waste.
