Renewable or Non-Renewable? - With a partner distinguish between these resources.

Renewable Resources - Resources than can be replenished. -These include biomass, water, geothermal, wind, and solar -Positives: significantly less pollution and most importantly, renewable energy are available everywhere throughout the world thus there is no chance of the sources becoming depleted in future. -Negatives: expensive to produce and replenish slowly.

Non-Renewable Resources - Resources than CAN NOT be replenished. -Nonrenewable energy sources come out of the ground as liquids, gases, and solids. -Positives: easy to transport and cost of production -Negatives: POLLUTION and when they are gone there is no coming back
