4. Impact of Renewable Energy Sources
The adoption of renewable energy sources, such as solar and wind power, is growing in the United States. These sources can significantly reduce reliance on grid electricity and lower electricity bills.
4.1. Solar Photovoltaic (PV) Systems
Solar PV systems convert sunlight into electricity using photovoltaic cells. These systems can be installed on rooftops or in open fields. When solar panels generate more electricity than a home needs, the excess electricity can be sent back to the grid through a process called net metering. Net metering allows homeowners to receive credits on their electricity bills for the excess electricity they generate.
The impact of solar PV systems on electricity consumption is evident in states with high adoption rates. For example, Hawaii, which has a relatively high number of residential net-metered PV systems, has lower average electricity purchases per residential customer compared to states with fewer solar installations.
