We examine how different renewable energy support policies affect innovation in solar and wind power technologies. The analysis is conducted using policy and patent data for a large sample of 194 countries and territories. The policy data allows distinguishing two dimensions of regulation, i.e....

A major concern regarding innovation in clean technologies in the EU is that the fragmentation of its innovation system may hinder knowledge flows and, consequently, spillovers across member countries. A low intensity of knowledge flows across EU states can negatively impact their technological...

We examine the effect of energy prices and technological knowledge on innovation in green energy technologies. In doing so, we consider both demand-pull effects, which induce innovative activity by increasing the expected value of innovations, and technology-push effects, which drive innovative...

The unprecedented health emergency and economic crisis triggered by the Covid-19 pandemic risks to be a setback for clean energy innovation efforts at a time in which faster progress is needed. The report quantifies the needs for technology innovation and investment for a cleaner and more...

The paper aims to contribute to the longstanding technology-push vs. demand-pull debate and to the literature on renewable energy diffusion and renewable energy policy assessment. We argue that in addition to the traditional push-pull dichotomy, the drivers of technological change must be...
