The city of San Marcos, California is facing a major challenge; how to reduce its carbon footprint and become more energy efficient. For years, the city has relied on traditional energy sources such as coal, oil, and natural gas to power its homes and businesses. Unfortunately, these sources of energy generate large amounts of carbon emissions, which contribute to climate change. San Marcos has made a commitment to reduce its carbon footprint and become more environmentally responsible. The city has identified several initiatives to help it reach this goal, one of which is the installation of solar panels.
