On Monday I’ll be speaking on a panel at the NASEO Annual Meeting titled “What’s Next for Energy Efficiency: Grid Interaction.”
With increasing amounts of wind and solar generation, we will need to shift our thinking on energy efficiency as well. Programs that focus on annual electric consumption or electric peak are no longer nuanced enough. We need create buildings that use energy when renewable energy with low or no marginal cost is available and conserve energy when it’s more expensive. The average building life in the U.S. is 75 years, so we need to be thinking now about how we want buildings in 10 years to be consuming energy.
For this panel, I will be discussing a recent study done with Xcel Energy looking at the Time Value of Energy Efficiency. The study looked at today’s marginal cost savings and carbon emissions for 20 common new construction efficiency measures along with project costs and emissions for 2028. As the marginal cost and emissions for each unit of electricity saved comes down, it will be increasingly important to tailor efficiency incentives to approaches that support a more renewable based generation.
