US Electricity costs predicted to double in next 25 years, thats what a report to be released today says the cost of electricity could double by 2030.  The Energy Supply Association (ESA) commissioned the research that found a 30 per cent cut in greenhouse gas emissions in the next 25 years would mean power would become twice as expensive.  ESA chief executive Brad Page says it would cost between $35 billion and $75 billion. What you need to do is have the widest ranges of technologies available if you want to do it in a least cost manner,” he said.  “For example, least cost will actually come about by having nuclear and advanced carbon capture and storage available.  “Each time you remove one of these options you actually find that the cost of meeting these deep emission cuts goes up and in some cases very significantly.”
