HELP ME 99+ POINTS!!! Describe which renewable resources are used primarily to produce electricity and which renewable resources

NikAS [45]

renewable resources are used primarily to produce electricity include wind and hydro-electric power. they require large mechanical structures e.g. wind turbine and water dam in order to generate electric energy. Therefore they are not appropriate for home use.

renewable resources are readily used as heat sources for homes include solar-water heating system in which water is heated by sunlight and circulated around the house. Wood burning for heat can also be considered a renewable resource as long as the wood comes from a sustainable logging cycle.
