On the opening day, the second annual "Singapore Energy Lecture" was delivered by Daniel Yergin, the Chairman &amp; co-founder of Cambridge Energy Research Associates. In his speech, Yergin discussed the development of unconventional shale gas, calling it "one of the most important innovations of this decade" - and that the use of natural gas is expected to grow substantially in Asia, especially in Liquefied natural gas (LNG) form. He also said that oil supply will be supplied by the use of technological innovations, as only about a fifth of the oil reserves that could be recovered had been extracted.
