This article reviews the concept of an energy technology innovation system (ETIS). The ETIS is a systemic perspective on innovation comprising all aspects of energy transformations (supply and demand); all stages of the technology development cycle; and all the major innovation processes,...

One explanation for the modest pace of efforts to mitigate climate change, both federally and internationally, is that constituents do not ascribe much beneficial value to new laws that change the way we produce and consume energy. We surveyed estimates of consumer willingness to pay (WTP) for...

Rising expectations about future demand for new technologies increase the incentives for investments in innovation by enlarging payoffs to successful innovations. How well does this notion of "demand-pull" apply to non-incremental technological change when demand is largely attributable to...

The combination of substantial public funding of nascent energy technologies and recent increases in the costs of those that have been most heavily supported has raised questions about whether policy makers should sustain, alter, enhance, or terminate such programs. This paper uses experience...

Both anecdotal evidence and the innovation literature indicate that important advances in energy technology have made use of knowledge originating in other technological areas. This study uses the set of U.S. patents granted from 1976 to 2006 to assess the role of knowledge acquired from outside...

Buildings are crucial to addressing energy problems because they are large consumers of end-use energy, and potential exists to dramatically improve their efficiencies. However, the pace of innovation in buildings is generally characterized as inadequate, despite the implementation of an array...

In building a governance regime to address climate change, should we prioritize the development of global institutions or national ones? This paper focuses on two neglected characteristics to inform the governance problem: the incentives for investment in low-carbon energy technology and the...
