the government should use solar energy not only because it decreases the use of fossil fuels, but also because solar energy promotes a healthy economy. Solar energy is proven to be economically efficient through a process called net metering. Net metering allows non-utility solar customers to produce and sell additional energy to local energy facilitators. One researcher explains that when consumers have to pay their next energy bill, they only pay the difference between the energy they produce and the energy they use; therefore, net metering reduces overall energy bill costs (“microgeneration”). Chemical engineer Goswami notes that “solar collectors have highly concentrated storage” (11). Since large amounts of solar energy can be stored, the net metering process allows consumers to use solar energy as a very efficient way to save money. Solar energy also allows local businesses to grow and participate in the energy market. America's local levels play an important role in maintaining the health of the country's capitalist economy. Taking the initiative to start a market and creating competition with other local businesses allows the market to grow. David Biello comments that the solar industry "[increases] competition for mini-monopolies" in places like Arizona ("Solar Wars"). Another local solar company owner, Morgan Walton, describes the ups and downs his company faces in the energy industry (169-170). Although not all local companies are guaranteed to thrive in the energy market, the nature of competition promotes a healthy atmosphere in the country's capitalist system.
