John Kight, an engineer and owner of home rainwater-catchment and solar-energy systems, will offer the latest technological information and practical advice for using water- and energy-saving technology. Participants will hear a presentation in the CNC library then carpool to Kight’s home to see his systems in action. Kight’s rainwater-catchment system supplies all the water for his family’s household and landscape needs. His grid-connected solar energy panel is also tied to a battery backup and sufficient energy to power all of his appliances with the exception of air conditioning.
