As it does so, the kinetic energy of the water can be used to drive turbines generating electricity. We can drive turbines straight off a water wheel in a river but we can get lots more energy and control over the amount we produce by damming a high valley and allowing the water to run down as we need power.
Obviously the different films and scenes where in different places, but like in harry potter and the prisoner of askaban (with the night bus), and all the hogwarts scenes wherâ¦e filmed somewhere in or near London. A lot of it was filmed in leavesden film studios in Watford, Hertfordshire.
The first series was mostly filmed in Slaithwaite, with some exterior shots filmed in the village of Baildon, but from series 2 onwards, Marsden was used as the principal filming location.
