Actually there is also a different incentive for going into EE. Systems of today are highly predictable when it comes to 24/7 operational aspect. Not too much noise. Lots of centralised large power sources and predictable consumption. Once generation trough means of connecting renewables to the grid becomes major thing rather than minor, things will go from a predictable to predictable baseline + the renewables noise. Operational aspect becomes insanely more complex and load flow calculations everyone is doing today will become less reliable. More stress will be put into monitoring/operational aspect than is being put today simply because uncertainty of renewables.
