§ 185-66 Purpose.
It is the purpose of this regulation to promote the safe, effective and efficient use of installed renewable energy systems that reduce on-site consumption of utility-supplied energy while protecting the health, safety and welfare of adjacent and surrounding land uses and properties. It is the Township's goal to provide property owners and business owners/operators with flexibility of satisfying their on-site energy needs and assuring continuing electrical supply during utility blackouts for such necessities as pumping well water, running freezers, refrigerators, air conditioners, and lighting for health and safety. Also, it is a secondary goal that through the progressive employment of renewable energy technology in the Township, a reduction in overall energy demands within the Township can be realized.
