Solar photovoltaic (PV) and onshore wind are now the cheapest options for new power generation, but enabling policies are still needed to speed up deployment, particularly in lower income countries. Public financial support measures most likely to facilitate tipping in lower income countries are concessional finance, grants, and loan guarantees; grid investments; and fossil fuel subsidy reform. Increased transfers are needed from the international donor and finance community.
