Presentation on theme: "ALTERNATIVE ENERGY & ELECTRICITY REVIEW. RENEWABLE RESOURCES Renewable resources are natural resources that can be replenished in a short period of time."— Presentation transcript:
RENEWABLE RESOURCES Renewable 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. Why? Solar energy can be converted to electrical energy and water heaters run on electricity.
Which of the following would be classified as a renewable energy source? Hydropower, because water is everywhere and is easily available.
Which of the following energy sources is considered non-renewable? Propane, because once it runs out it is gone.
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 Draw this Circuit In your Notes!!!
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. Parallel Circuits Draw this Circuit In your Notes!!!
