What can be done to combat the risk-adverse nature of both the regulators and the technology purveyors?
As water is stretched and regulations around it tightened, the energy industry feels the burden. This can result in everything from reduced operations and higher costs for consumers to,in extreme cases, blackouts and gas and electricity shortages.
