An aging infrastructure and increasing demand for energy makes technology more important than ever in meeting and sustaining the power needs of the world. In its 2012 World Energy Outlook, the International Energy Agency said global energy dependency will grow by more than 30 percent between now and 2035. As the shift to more renewable sources catches on, questions are raised about how to make grids more flexible and better able to accommodate intermittent renewable generation. Alstom Grid believes high voltage, direct current (HVDC) technologies are part of the answer.
