If a picture is worth a thousand words, a recent large-scale restoration project yielded about 1.4 million - not to mention a lot of refreshed faces.
The U.S. Department of Energy’s (DOE’s) Vehicle Technology Office (VTO) has played a critical role in enabling electrification and reducing fuel consumption in the automotive sector. However, the off-road vehicle sector accounts for 8% of transportation fuel, and that share is likely to increase over time as onroad vehicles move towards electrification. DOE can again play a key role in the off-road vehicle market by providing tools that can be used by academia and the industry to evaluate the impact of advanced technologies. The need for a pre-competitive simulation tool was also identified during a 2019 DOE-led workshop at Argonne National Laboratory that included OEMs and suppliers to this market. Autonomie, a powerful and robust system simulation tool for vehicle energy consumption and performance analysis, was developed by Argonne National Laboratory in collaboration with General Motors. Its application covers energy consumption and performance analysis throughout the entire vehicle development process by leveraging its plug-and-play powertrain and vehicle model architecture and development environment
This presentation reviews trends in the national community solar market, with project and subscriber data through 2020. It summarizes data on community solar deployment over time, by state, and by project characteristics. It also examines how market factors have shaped community solar deployment and explores data on the community solar value proposition to subscribers, energy burden, and affordable housing benefits.
This issue brief is for state and local governments that want to track the energy impacts and performance of a Commercial Property Assessed Clean Energy (C-PACE) financing program. C-PACE programs provide a mechanism for commercial property owners to finance energy improvements and can provide a variety of both private and public benefits.

International Holocaust Remembrance Day is an annual commemoration designated by the United Nations that includes worldwide memorial services, vigils and more. January 27 is the anniversary of the 1945 liberation of Auschwitz-Birkenau, which was the largest Nazi concentration camp operated by Nazi Germany during World War II.
Freshwater availability is operationally critical for thermoelectric power plants. Trends indicating a growing population, along with increasing threats stemming from the changing climate could possibly set off water scarcity issues for U.S. thermoelectric generation in scarcity-prone regions in the country. This report is an update to a previous water needs analysis which was conducted in 2020 by the Department of Energy’s National Energy Technology Laboratory (DOE/NETL).
How can a lightweight back-assisted exosuit help material handlers decrease back strain from repetitive lifting tasks? What are the benefits of a passive robotic shoulder support in reducing fatigue and injury for environmental cleanup workers? How can mechanical devices reduce joint and muscle injuries in a manufacturing environment? These are some of the questions a group of Laboratory engineers are asking in their ongoing quest to identify and evaluate specially designed wearable advanced technologies to assist workers and help keep them safe.
As the U.S. works to meet emissions reduction goals and modernize power sector operations, residential buildings - which account for 21% of the total U.S. electricity consumption - will play a key role. Residential buildings with energy efficiency and distributed energy resources are able to provide value to multiple stakeholders, including the occupant, utility, and society at large. To account for this, multiple metrics that capture the value each stakeholder gets are required. This report contains analysis of a unique solar plus storage community in Vermont, including the calculation of multiple metrics and a unique "score card" that succinctly captures all of the value in a single figure.
Building on the successfully completed effort to calibrate and validate the U.S. Department of Energy’s ResStock™ and ComStock™ models over the past three years, the objective of this work is to produce national datasets that empower analysts working for federal, state, utility, city, and manufacturer stakeholders to answer a broad range of analysis questions. The goal of this work is to develop energy efficiency, electrification, and demand flexibility end-use load shapes (electricity, gas, propane, or fuel oil) that cover most of the high-impact, market-ready (or nearly market-ready) measures. “Measures” refers to energy efficiency variables that can be applied to buildings during modeling.
The purpose of this “Low Density Steels for Transportation Applications” project was to develop an alloy composition and processing parameters that would result in a material suitable for use in automotive structural components at a reduced density over the current advanced high strength steel (AHSS) materials used. The project work successfully developed a robust alloy capable of exceeding project mechanical property targets at each stage of development, with an 8% density reduction over benchmark AHSS materials (7.8 g/cm3). The developed alloy has the potential to offer significant vehicle lightweighting and improved fuel economy, without sacrificing the increased passenger safety of more traditional AHSS. Through the three tasks of the project, (1) Alloy design and small-scale laboratory evaluation, (2) Laboratory development of hot rolled material and (3) Laboratory development of a cold rolled material, the laboratory work utilized advanced characterization and analytical methods on novel alloy compositions subjected to both conventional and non-conventional processing operations.
This report describes the implementation of a Max Tech HVAC upgrade scenario, which involves replacing boilers and RTUs with heat pumps, as we as adding economizers, heat recovery, and demand control ventilation to all applicable systems.

This report evaluates the benefits of decommissioning six legacy FFESD purchased HPC clusters and consolidating services and workloads into a new HPC cluster named HELIOS. The findings demonstrate significant reductions in the data center power and cooling requirements, data center footprint, and operational overhead, while simultaneously increasing computational capacity.
This project, a Cooperative Research and Development Agreement (CRADA) partnership between A. O. Smith and Oak Ridge National Laboratory (ORNL), was initiated to develop a heat pump water heater (HPWH) based on thermoelectric (TE) heat pump technology capable of seeing widespread market adoption by having a one-year payback versus electric resistance options.
