Mechanical energy is the energy of __________. All over the world, we are using mechanical
energy to generate __________ for our homes, schools, and businesses.
Wind and water are two __________ that offer incredible amounts of mechanical energy. Scientist and engineers have been able to harness both the power of the wind and __________ in rivers, tides, and ocean currents to generate electricity.
Wind __________ have been in use for hundreds of years. Even though their size and materials have evolved over time, their purpose remains the same: generate energy. Today, we find wind turbines in __________, coastal regions, and the plains. These areas offer an obstructed terrain where wind speeds are at their highest. These tall, white structures use long blades that move with the wind, powering a generator, and transforming mechanical energy into electricity. The electricity is then sent though wires into power grids for use in small towns and big cities.
Moving water, like wind, can be captured in much the same way. Turbines fitted into __________ turn as water moves over them. The motion powers a generator that __________ mechanical energy into electricity. __________ is one of the greatest means of generating electricity.
Wind and water are both __________ resources and provide scientists, engineers, and
energy companies with an alternative energy resource for generating electricity.
