1. LEVERAGING PRIVATE FINANCE
AND INDUCING INNOVATION FOR
CLIMATE MITIGATION THROUGH
POLICY DESIGN

Ottawa, Nov. 8th, 2012
2. Background (1)
• Technological innovation and allocation of private finance towards „clean‟
energy (and other environmental fields) share two key attributes
• Public policy context plays a key role in determining the returns on
investment
• Many of the expenditures are irreversible (i.e. non-recuperable R&D
expenditures; long-lived and „specific‟ capital)
Small differences in policy conditions can have long-lived implications for
trajectory of the economy
Small changes in policy conditions can have significant implications for the
rate of change of transition of the economy
3. Background (2)
1. Innovation
• role of different policy instruments on high-value renewable energy
patents and alternative fuel vehicle patents
• role of policy stringency, flexibility and predictability on „environmental‟
patents more generally
• the role of technology agreements and the CDM on technology and
knowledge transfers
2. Investment and Finance (preliminary)
• role of different policy measures on allocation of private finance for
projects of different technological maturity
• the extent of crowding out/crowding in which exists between different
public (i.e. grants) and private (i.e. equity) sources of finance;
•the benefits of complementary projects in terms of ease of access to
finance (e.g. investments in transmission infrastructure and grid quality)

6. Prices matter – and spur innovation
The Effect of an Energy Tax on High-Value Patent Counts in
Combustion Efficiency and Renewable Energy
Source: OECD Energy and Climate Policy and Innovation (2012). Based on estimation of
sample of OECD economies over period 1978-2008. Results indicate that if oil price is
approximately equal to prices reached in 2008 oil shock => switch from fossil fuel combustion
efficiency innovation to renewable energy innovation. See also ENV WKP 45
7. Pricing as a Necessary but not Sufficient
Condition
• Difficulty of targeting environmental „bad‟ directly and excessive
administrative costs – i.e. environmental policy and transaction
costs
• Secondary „non-environmental‟ market failures – i.e. information
failures, split incentives, network externalities
• „Credibility‟ of policy-induced price signals over the longer term
may not be sufficient for risky investments
• Inertia in the market which can favour incumbent firms and
technologies – “deadweight of past” may correlate with
environment-intensity
=> Therefore – need to „unbundle‟ the attributes of policies which
lead to innovation (beyond overly simplisctic MBI > CC)
8. Principles of environmental policy design in order to
encourage 'green' innovation
• Stringency – how ambitious is the policy objective
relative to “BAU”
• Predictability – how certain and credible is the signal
given by the policy
• Flexibility – how much space is provided to identify
new technologies and methods
• Incidence – how closely does it target the underlying
policy objective
• Depth – does it generate incentives across the full
range of possible outcomes

12. Policy Impacts and Distance from “Market”
• To induce a 1% increase in electric vehicle innovations, the
alternatives are:
– Increase targeted public R&D by 14% (i.e. $26 mln instead of
$23 mln per year per country, on average)
– Increase post-tax fuel price by 63% (i.e. $1.30 instead of
$0.80, on avg)
• To induce a 1% increase in hybrid vehicle innovations, the
alternatives are:
– Increase targeted public R&D by 53% (i.e. $35 mln instead of
$23 mln per year per country, on average)
– Increase post-tax fuel price by 5% (i.e. $0.84 instead of
$0.80, on avg)
14. Directing Change Without “Picking Winners”
• Since “neutral” pricing of externality is not always sufficient
and/or feasible = > necessity to be „prescriptive‟ (at least to some
extent) => main challenge for policy makers
• Some general principles:
• Support a „portfolio‟ of projects and technologies to
diversify downside risk of getting it “wrong”
• Benefits of chosen portfolio should be robust with respect
to information uncertainty (i.e. ancillary benefits)
• Identify “local general purpose” technologies and
investments which complement a variety of
emission-reducing strategies
=> An example related to renewable energy
16. Challenge of Increased Penetration of
Renewables
• The most important renewable energy sources
(wind, solar, ocean/tide) are ‘intermittent’
• Generation potential is subject to significant temporal variation
(minutes, hours, days, seasons), which is uncertain and often
correlated, and negatively correlated with peak demand (in
some cases)
• This means that increased capacity of renewable energy
generation is not a perfect substitute for ‘dispatchable’
generation capacity (e.g. fossil fuels)
• Challenge of LOLP becomes greater as share rises – note that
some countries have targets > 40%, where capacity credit starts
to converge to zero
17. Means of Overcoming Intermittency
• Reduce correlation of variation in intermittent sources
and/or allow for ex ante/ex post adjustment. How?
o “Back up” dispatchable sources (include some hydro)
o Disperse (space) and diverse (type) of sources
o Improvements in load management and distribution
o Trade in electricity services (states, countries)
o Investment in advanced energy storage
o Malleability of demand (e.g. smart grids)
• Benefits hypothesised to vary at different levels of
„penetration‟ of intermittent renewable power
