gas (GhG) emissions by several gigatons of
CO2-equivalents per year, while affordably meeting the
world’s growing demand for energy, will require the
deployment of tens of terawatts of low-carbon energy
production and end-use technologies over the next
several decades. Improvements are needed because
existing technologies are expensive, limited in
availability, or not sufficiently reliable for
deployment at that scale. At the same time, the presence
of multiple market failures implies that private actors
will under-invest in climate-related innovation without
government intervention. To help resolve this impasse,
policy makers will need to select from a vast set of
policy instruments that may stimulate innovation in, and
adoption of, these technologies.
In this thesis, four studies are used to contribute to understanding the characteristics of the innovation process—and its interactions with policy—for low-carbon energy technologies. These include analyses of: (1) the trends and future prospects for U.S. energy R&D investment, (2) the effectiveness of demand-pull for wind power in California, (3) the sources of cost reductions in photovoltaics (PV), and (4) the effect of widespread deployment of PV on the earth’s albedo. When considering these studies together, the uncertainty in expectations about future policies that increases the risk for investments in innovation emerges as a central problem. As observed in multiple instances in this thesis, the lags between investments in innovation and the payoffs for private actors can last several years. These distant payoffs rely heavily on the status of future government policies because externalities are pervasive for the development of climate-relevant technologies. When expectations about the future level—or existence—of these policy instruments are uncertain, then firms discount the value of these future policies and under-invest in innovation.
The diffusion of institutional innovation is a necessary precondition for the technological innovation required to address climate change. If long-term GhG reduction targets are to be relied upon to stimulate innovation in low-carbon energy technologies, then policy makers need to address the competing goals of increasing the time-consistency of policy and retaining the ability to make adjustments that incorporate new information.
