NEW DELHI, July 4 (Xinhua) -- The Economic Survey 2018-19 tabled at the Indian Parliament Thursday pitched for fresh investments of 330 billion U.S. dollars in the renewable energy sector over the next decade through 2030.

"Additional investments in renewable plants up to year 2022 would be about USD 80 billion at today's prices and an investment of around USD 250 billion would be required for the period 2023-2030. Thus, on an annualized basis, investment opportunity for over USD 30 billion is expected to come up for the next decade and beyond," reads the estimates put in the survey report.

The Economic Survey was tabled by Finance and Corporate Affairs Minister Nirmala Sitharaman at the country's parliament.

The survey states that renewable energy sources are a strategic national resource.

"Harnessing these resources is part of India's vision to achieve social equity and energy transition with energy security, a stronger economy and climate change mitigation," the report said.

"While increasing access to energy is important, it is also imperative that this comes at much lower costs to the environment than it has happened historically in advanced economies."

The survey stated that India was undertaking one of the world's largest renewable energy expansion programmes and noted the share of renewable energy is progressively increasing in the Indian electricity mix.

"The share of renewable (energy) in total generation was around 10 percent in the year 2018-19 compared to around six percent in 2014-15," the survey said.

"Now, globally, India stands fourth in wind power, fifth in solar power and fifth in overall renewable power installed capacity. The cumulative renewable power installed capacity has more than doubled from 35 GW on 31 March, 2014 to 78 GW on 31 March, 2019. The target is to achieve an installed capacity of renewable based power of 175 GW by the year 2022."
