In 2010, we can expect that oil and gas prices will again increase beyond the US$100 per barrel, as the global economy recovers gradually from the global recession and uses more oil and gas. It is therefore important for the general public to read and understand more about complex energy issues which affect their lives. This useful energy book, based on lectures delivered at the ISEAS Energy Forum, as well as papers written by invited experts, provides a means to access energy information. It is part of the ISEAS Energy books series which serves to educate and raise public awareness on energy issues.
