Renewable resources are those resources that can be naturally replenished. Consuming renewable resources too quickly either lessens or completely destroys their ability to replenish or regenerate themselves. So, even though renewable resources are technically limitless, there is a chance that they could become temporarily or permanently nonrenewable. Students learn about renewable energy (passive and active solar energy, wind, hydropower, geothermal energy, and biopower). They also learn about bioproducts and how to make good decisions about renewable resource use at home, in the community, and at school.
