Clayton is the first Green Power Community in Missouri and one of only 37 in the country.
With the goal of turning 2 percent or 670 megawatt hours of the community energy consumption into renewable energy credits (REC) by Earth Day 2011, the City of Clayton launched its Green Power Community challenge in April of 2010. Through a joint effort with Ameren Missouri Pure Power, Clayton-based Microgrid Energy and Clayton businesses and residents, the City achieved is GPC status in March 2011, a month ahead of its goal.
Renewable Energy
Opportunities are available for operating your home or business with sources of renewable energy. These energy sources have the potential to heat, cool or provide electricity to buildings with lessened air emissions. These energy sources are considered renewable because they are naturally replenished at a faster rate than they are used. Initial installation costs for these systems are offset by energy savings over time.
Ground source heating and cooling systems use the relatively constant temperature under the earth's surface to move warmer air into homes and businesses during the winter months and out of buildings in the summer months. These systems can be four times as efficient as conventional heating and cooling systems.
Sunlight can be used to generate electricity using photovoltaic (PV) and solar thermal technologies. PV panels capture sunlight and release electricity. Solar thermal systems heat water or air for residential and commercial uses. Solar thermal systems can also collect sunlight to heat water and create steam to turn a generator and produce electricity.
