The NPS Energy & Water Management Program works to reduce energy and water consumption throughout the agency and provides guidance to parks in order to increase energy and water efficiency. The program is responsible for assisting parks in improving the sustainability of NPS facilities, tracking and reporting performance data, and promoting the use of renewable energy resources and alternative fuels.

Energy & Water Consumption

The NPS produces annual energy reports to provide a snapshot of how the service is performing against goals set out in federal Executive Orders (EO) such has E.O. 13693 Planning for Federal Sustainability in the Next Decade. Specifically, the report summarizes total annual consumption data for energy and water, associated costs, and estimated greenhouse gas (GHG) emissions. The NPS uses this information to understand year-to-year changes in facility energy intensity (energy management), eligible renewable electricity use as a percentage of total use (renewable energy requirement), reduction in potable water consumption intensity (water intensity goal), metering of electricity use, and percent of new building designs that meet the Federal Building Energy Efficiency Standard.

Energy & Water Audits

The Energy Independence and Security Act of 2007 (EISA) requires federal agencies to conduct energy and water evaluations at facilities that consume at least 75% of agency-wide energy use. To fulfill this and other federal mandates, the NPS conducts energy and water audits at many parks throughout the service. This effort also provides parks with useful information concerning energy and water consumption as well as their progress toward meeting performance targets.
