How can governments promote renewables?

Governments can promote renewables by providing incentives such as tax breaks and subsidies to businesses that install renewable energy systems, creating government-backed renewable energy funds, mandating renewable portfolio standards, offering additional financing for renewable energy projects, and providing grants for research and development of new renewable energy technologies. Governments can also set more stringent renewable energy targets, create renewable energy education and marketing campaigns, and establish tax credits for individuals and businesses that invest in renewable energy systems. Additionally, local governments can create zoning ordinances that promote renewable energy technologies such as rooftop solar, wind turbines, and geothermal systems.
