Disadvantages: Dams affect river ecosystems and An adequate supply of water from rain or snow is required for hydroelectricity plants to continue operation.

Famous scientists

Albert Einstein: Einstein's break throught was writing a paper with a new understanding of the structure of light. He also proposed a way to put the kinetic theory to a new and crucial experimental test.

Benjamin Franklin: Franklin's break throught was proved lightning was electricity. He did this by using lightning rods to redirect electricity away from buildings to keep them from burning down. By tying an iron key to a kite string during a storm, he was able to identify the electrical charge
