Japan, holding the G20 presidency in 2019, asked the International Renewable Energy Agency (IRENA) for a status and outlook report on these variable renewable energy (VRE) sources. IRENA has engaged with successive G20 presidencies since 2015 on a toolkit for renewable energy deployment.

Optimal energy transition with variable and intermittent renewable

Second, the standard Hotelling-like literature ignores the variable and intermittent nature of renewable sources, which is the main obstacle to their penetration in the electric mix. An exception is Helm and Mier (2018), who build a dynamic model with a fossil fuel, a variable renewable source and a storage technology. Their aim is to study the
