What Are Some Renewable Energy Technologies?
Solar panels on rooftops can provide a large amount of energy for a home or business and may make the electric meter run backwards; Cost: $7-$12 per watt before rebates Wind turbines harness wind energy. A single medium sized wind turbine with good wind conditions can provide enough energy for eight 3-bedroom homes; Cost: $2,000-$7,000 per kW (source: www.windfarmersnetwork.org ) Biomass energy can come not only from plant and animal manure, but also from decaying landfills. Electricity can be generated from methane gas that is produced as the biomass decomposes; Cost: varies depending on source.
