Wind turbines are being used more and more to generate electricity. in fields of hundreds of turbines, the turbines spin as wind pushes them, and the spinning motion is converted into electrical energy that can be sent to homes and businesses. however, not all of the kinetic energy of a spinning turbine gets converted into electrical energy. what best explains why the turbines are not one hundred percent efficient? the turbines are spinning outdoors, and solar energy from the sun interferes with how machines work, causing kinetic energy to be lost to the air. some of the energy of the wind’s motion is converted into a force by the machine, so some energy is lost to force. since electrical energy is more useful than the kinetic energy of wind, the wind turbines are more than one hundred percent efficient. as the turbines spin, friction occurs between different parts of the machine, so some of the energy is converted into heat instead of electrical energy.

Which sentence describes a limitation of tidal power as an energy source? tidal power renewable energies harness power from natural resources. these technologies are useful because natural resources, such as sunlight and wind, continually replenish over time. solar panels and wind turbines are examples of renewable energy sources. tidal power is another lesser-known renewable energy source that harnesses power from ocean tides. the tides occur based on the location and movement of the moon around the earth. because the moon and the oceans are constants, people can use energy from tides indefinitely. as with other renewable energies, tidal power is a promising future energy source. a tidal power plant looks and functions similar to a wind turbine. with wind power the wind rotates a turbine to produce electricity, whereas with tidal power water rotates a turbine to produce electricity. other than the installation and occasional maintenance, tidal turbines can produce abundant amounts of energy from ocean tides. local governments and companies have teamed together to install tidal turbines. a group of these tidal turbines can power entire towns. before governments or companies install tidal turbines, the local tides and geography must be studied extensively. not every coastal region experiences tides large and powerful enough to warrant building tidal turbines. nevertheless, numerous regions around the world have the tides and geography suitable for this fascinating power source. for example, areas of canada, western europe, and australia have large tides where tidal power stations could harness energy and create electricity
