Water turbines were developed in the 19th century and were widely used for industrial power prior to electrical grids.Now they are mostly used for electric power generation. 0000001554 00000 n 872 24 How do you think these two energy sources differ from each other? 44. ���ރPY�����U N'��)�].�u�J�r� What do you think the phrase "energy source" means? This type of scheme requires no water storage but instead diverts some of the water from the river which is channelled along the side of a valley before being 'dropped' into the turbine via a penstock.
