 Renewable energy sources or RES capture their energy from existing flows of energy; from on-going natural processes, such as sunshine, wind, wave power, flowing water (hydropower); biological processes such as anaerobic digestion; and geothermal heat flow.

The most common definition is that renewable energy is from an energy resource that is replaced by a natural process at a rate that is equal to or faster than the rate at which that resource is being consumed. Renewable energy is a sub-set of sustainable energy.

This class will help students understand renewable energy, with an emphasis on solar and wind, as it relates to the residential sector and will provide resources for further exploration. Free. Info: 972- 742-2296.
