Economies of scale are achieved by shrinking the labor contribution relative to output, which explains why utility-scale energy is less expensive than do-it-yourself energy.
Distributing renewable energy through customer-sited systems increases job-hours per energy unit produced as well as promoting entrepreneurship and small business development. . . .
