Governments can play an important role in clean energy investments. Government facilities and military operations are often significant “offtakers” of energy, thus there is an opportunity for the public sector to invest in clean energy through energy efficiency upgrades, renewable energy generation, and microgrids. The government can also support clean energy investment through national development banks, green banks, guarantees, and incentives. Public sector institutions also play an important role in establishing an enabling environment for clean energy investments. In more regulated markets, the utility may be a state owned utility, and thus the utility could also be viewed as an arm of government.
