B787 is a mostly electric airliner. There are far fewer hydrolic/cable operated systems than in previous planes. This is much safer since a explosion/leak/breach/clog in a hydrolic line won't take out an entire hydrolic system (most planes have 3 systems and fuse valves to mitigate this). However, since there are so many electricly operated systems, you really need power. The B787 as is No Bleed [1], so electrical power is also used to pressurize it [2]. Need Electric Power.
