28.02.2014 - IEA says system transformation key to low-carbon future
International Energy Agency said expanding the use of renewable energy resources like wind and solar requires transforming the system to be cost effective. IEA published a 238-page book Wednesday that said technologies like wind power and solar photovoltaics are "crucial" to a future energy mix, though there are "unique" questions remaining in terms of cost and reliability. "Electricity generation from both technologies is constrained by the varying availability of wind and sunshine," the IEA said. "This can make it challenging to maintain the necessary balance of electricity supply and consumption at all times."..............................................Full Article: Source
