The term 'Domestic Content Requirement' is sometimes seen in the news with reference to

  1. A.Developing solar power production in our country
  2. B.Granting licences to foreign T.V. channels in our country
  3. C.Exporting our food products to other countries
  4. D.Permitting foreign educational institutions to set up their campuses in our country

Correct answer

A. Developing solar power production in our country

Explanation

The correct answer is A, developing solar power production in our country. Domestic Content Requirement (DCR) is the rule that certain solar projects must use solar cells and modules made in India.

Under the Jawaharlal Nehru National Solar Mission, launched in 2010, part of the solar capacity was reserved for developers who bought Indian-made cells and modules, to build a home manufacturing base. The United States challenged this at the WTO, and in 2016 the WTO ruled that India's DCR measures broke the national treatment rule of trade law. India still applies DCR in government-backed schemes such as rooftop solar subsidies and PM-KUSUM, which are framed as government procurement.

B is wrong: TV channel licensing is governed by broadcasting rules, not DCR.

C is wrong: food exports are about standards and export policy, not domestic content.

D is wrong: foreign university campuses are regulated by the UGC, not by a content requirement.

Exam tip: DCR = made-in-India solar cells and modules; National Solar Mission; WTO case India vs US, 2016.

Consider the following statements :

I. Carbon dioxide (CO2) emissions in India are less than 0.5 t CO2/capita.

II. In terms of CO2 emissions from fuel combustion, India ranks second in Asia-Pacific region.

III. Electricity and heat producers are the largest sources of CO2 emissions in India.

Which of the statements given above is/are correct?

  1. A.I and III only
  2. B.II only

  3. C.Reducing the adverse effects of solar wind on the Earth
  4. D.Reducing the global warming
