Answer:1. alternating
2. direct
3. reservoir
4. Solar cells
5. The sun heats up the atmosphere as Earth spins, creating areas of high and low temperature. This temperature difference causes the wind to start moving through convection, which can then drive a wind turbine to produce electricity.
A spinning turbine can only generate electricity in the form of a/an Alternating current. Of all the alternative energy technologies presented in this section, only solar panels produce a/an Direct current. Methane can be emitted from the Reservoir near a hydropower dam. Solar cells are the only energy generation technology that does not require the use of a turbine.
How does a spinning turbine generate energy?
- A moving fluid—water, steam, combustion gases, or air—pushes a sequence of blades mounted on a rotor shaft in a turbine generator.
- The rotor shaft of a generator is spun/rotated by the force of the fluid on the blades.
- The rotor's mechanical (kinetic) energy is converted to electrical energy via the generator.
What role does the sun play in allowing power to be produced with wind turbines?
- The wind is propelled by the sun, which heats some portions of the earth more than others.
- The movement of air is referred to as wind. The sun heats the air, which causes it to rise.
- As a result of the rising warm air, colder air from the surrounding areas rushes in to replace it.
