NAME:
IN BRAZIL, MUCH OF THE ELECTRIC ENERGY THAT REACHES OUR HOMES COMES FROM HYDROELECTRIC PLANTS, BECAUSE OUR COUNTRY HAS MANY RIVERS.
FOR THE CONSTRUCTION OF A HYDROELECTRIC POWER PLANT, IT IS NECESSARY THAT THERE IS A RIVER WITH A LARGE AMOUNT OF WATER. INITIALLY IT IS NECESSARY TO BUILD A DAM TO FORM A RESERVOIR. WHERE THE RIVER FLOWS BEFORE THE DAM, A GENERATOR WITH GEARS THAT WILL ROTATE WITH THE PASSAGE OF WATER AND GENERATE ELECTRIC ENERGY IS INSTALLED.
THE DAMAGED WATER, BEFORE FOLLOWING THE RIVER'S COURSE, GOES THROUGH PIPES THAT TAKE THE TURBINES BLADES AND MAKING THEM RETURN, THIS SPIN IS WHAT PRODUCES THE ENERGY.
THE FORCE OF THE WATER IS TRANSFORMED INTO MECHANICAL ENERGY, WHEN IT MOVES THE BLADES AND THE GENERATOR TRANSFORMS THAT MOVEMENT INTO ELECTRIC ENERGY.
AFTER THIS PROCESS, ENERGY FOLLOWS FROM THE GENERATORS TO OUR HOMES THROUGH THE WIRES OF THE POWER NETWORK. THEREFORE, HYDROELECTRIC IS A CONSTRUCTION THAT, USING THE FORCE OF THE FALL OF WATER TO GENERATE MECHANICAL ENERGY, AND TRANSFORMS IT INTO ELECTRIC ENERGY.
THERE ARE OTHER SOURCES OF ELECTRIC ENERGY PRODUCERS, BUT THE CHEAPEST AND VISIBLE IN BRAZIL ARE HYDROELECTRIC.
