In 2017-18, the per-capita energy consumption is 23.355 Giga Joules (0.558 Mtoe) excluding traditional biomass use and the energy intensity of the Indian economy is 0.2332 Mega Joules per INR (56 kcal/INR). Net energy import dependency was 40% in 2018-19. Due to rapid economic expansion, India has one of the world's fastest growing energy markets and is expected to be the second-largest contributor to the increase in global energy demand by 2035, accounting for 18% of the rise in global energy consumption. Given India's growing energy demands and limited domestic oil and gas reserves, the country has ambitious plans to expand its renewable and most worked out nuclear power programme. India has the world's fourth largest wind power market and also plans to add about 100,000 MW of solar power capacity by 2022. India also envisages to increase the contribution of nuclear power to overall electricity generation capacity from 4.2% to 9% within 25 years. The country has five nuclear reactors under construction (third highest in the world) and plans to construct 18 additional nuclear reactors (second highest in the world) by 2025. During the year 2018, the total investment in energy sector by India was 4.1% (US$ 75 billion) of US$ 1.85 trillion global investment.
