The six-week long was shut the only shipping lane that was used by the Gulf countries to export crude oil (raw material for making petrol and diesel), natural gas (used to make fertilizer, generate electricity, turn into CNG to power automobiles and piped to household kitchens for cooking) and cooking gas LPG.This led to an energy crisis in several importing countries, including India which had to prioritise supply of gas. "Thinking that the Middle East is nearest to us and therefore all their resources (can be accessed easily), we should take it with a pinch of salt," Singh said at the Energy Security conclave organised by oil regulator PNGRB.

Singh said India's high energy import dependence makes it especially vulnerable in an increasingly fragmented world. "For the next 30-40 years. if you have multiple (powers), then you have everyday. war of supremacy," he said. He stressed that boosting domestic production is now critical....
