Energy security and climate change protection have risen to the forefront of energy policy--linked in time and a perception that both goals can be achieved through the same or similar policies. Although such complementarity can exist for individual technologies, policymakers face a tradeoff between these two policy objectives. The tradeoff arises when policymakers choose the mix of individual technologies with which to reduce greenhouse gas emissions and enhance energy security. Optimal policy is achieved when the cost of the additional use of each technology equals the value of the additional energy security and reduction in greenhouse gas emission that it provides. Such an approach may draw more heavily on conventional technologies that provide benefits in only one dimension than on more costly technologies that both increase energy security and reduce greenhouse gas emissions.
