Natural Resources and Energy Test Review

Why does an incandescent light bulb use more energy than a LED light bulb?

• There is more energy being converted to radiant energy instead of thermal energy in the incandescent bulb.

• There is more energy being converted to thermal energy instead of radiant energy in the incandescent bulb.

• Incandescent light bulbs are larger than LED bubs.

• Incandescent bulbs need a three-prong plug to produce light whereas an LED bulb needs a two-prong plug.

How does the way solar panels produce energy differ from wind mills and coal-fired and nuclear power plants?

• Coal, wind, and nuclear power are all cleaner energy sources than solar.

• Solar panels produce more harmful radiation than coal, wind, or nuclear power.

• Solar panels do not use electromagnetic induction to generate electricity.

• Solar is a non-renewable power source, and coal, wind, and nuclear are all renewable.

What purpose does a turbine serve in the generation of electricity?

• The turbine helps position heliostats in the perfect position to generate the most electricity.

• The spinning turbine creates the mechanical motion needed to create electromagnetic induction.

• The spinning turbine helps stoke the coal fire needed to generate electricity.

• The spinning turbine creates excessive amounts of static elctricity.

Why must batteries become more advanced for alternative energy to fully thrive?

• Current batteries are likely to explode if overused.

• Batteries are needed to efficiently convert electricity from coal-fired power plants into a cleaner alternative energy.

• Batteries are required to provide the electricity needed to make windmills and solar panels work.

• Large quantities of energy need to be able to be stored for times when energy production conditions are not optimal.
