There would be no need to subsidise renewables - if the taxes on emissions were at the right level, untaxed renewables would become competitive without subsidy.
A sector can be a grouping of institutions, such as by government (taxing authority), business (taxable profit-making), philanthropy (untaxed nonprofit), and household (taxable personal income).
Employers gave workers new untaxed benefits (such as vacation time, pensions, and health insurance), which increased real incomes even when wage rates were frozen.
