TERI Energy & Environment Data Diary and Yearbook (TEDDY) is an annual publication brought out by The Energy and Resources Institute (TERI) since 1986. It is the only comprehensive energy and environment yearbook in India which provides updated information on the energy supply sectors (coal and lignite, petroleum and natural gas, power, and renewable energysources), energy demand sectors (agriculture, industry, transport, residential, and commercial sectors), and environment (local and global). The publication also provides a review of the government policies that have implications for these sectors of the Indian economy. Each edition of TEDDY contains India’s commercial energy balances for the last four years that provide comprehensive information on energy flows within different sectors of the economy and how they have been changing over time.
