ALTERNATIVE ENERGY &

ELECTRICITY REVIEW

RENEWABLE RESOURCESRenewable resources are natural resources that can be replenished in a short period of time.

● Solar● Geothermal● Wind ● Biomass● Water

NONRENEWABLE RESOURCES

A nonrenewable resource is a natural resource that cannot

be re-made or re-grown

● Coal ● Natural Gas ● Nuclear● Oil

Solar panels on the roof of a house are most beneficial to a home owner because they

Can Heat water for the house.

Wire

Battery

Conductivity

• Conductors:– can carry electrical current easily.– Examples: metals (pennies and

paperclips)

• Semiconductors– Are in between conductors and

insulators.

• Insulators:–Do not carry electrical charge.– Examples: Glass and plastic

•Has only one path for electricity to flow

•If any part of the circuit is broken, then the all lights will go off.•Ex’s: Christmas tree lights

•In a series circuit, the light bulbs are DEPENDENT of each other.•It is like adding pinches to a hose.

Series Circuits

•Has multiple paths for electricity to flow•If any part of the circuit is broken, the remaining lights will stay on. •Ex’s: your home!!

•In parallel circuits, the light bulbs are INDEPENDENT of each other.•They have no effect on each other.
