Q

How is wind energy transferred to electricity

A

wind rotates the rotor blades, which convert kinetic energy into rotational energy. This rotational energy is transferred by a shaft which to the generator, thereby producing electrical energy

Q

How are solar cells transferred to electricity

A

When the sun shines onto a solar panel, energy from the sunlight is absorbed by the PV cells in the panel. This energy creates electrical charges that move in response to an internal electrical field in the cell, causing electricity to flow

Q

How is nuclear power transferred to electricity

A

Nuclear power reactors use heat produced during atomic fission to boil water and produce pressurized steam. The steam is routed through the reactor steam system to spin large turbines blades that drive magnetic generators to produce electricity

Q

How are geothermal resources transferred into electricity

A

Underground reservoirs of water are heated by magma, producing steam that rises and is channeled into the power plant. The steam then turns turbines, which turn generators, generating electricity
