Although cars have been around for more than a century, the material making them up has mostly stayed the same — steel. It’s only been in the last 25 years or so that advanced materials, ranging from aluminum and magnesium alloys to carbon fiber composites, have made their way into mass-produced passenger cars. These lightweight materials can cut a vehicle’s body and chassis weight in half, helping to increase fuel economy as well as the overall range of hybrids, plug-ins and all-electric cars.
A large part of the solution to reducing greenhouse gas emissions in the transportation sector could be uniquely filled by biofuels and bioproducts. The Energy Department’s Bioenergy Technologies Office (BETO), in partnership with the national laboratories, academia, and private companies, is pursuing biofuel research and development to reduce greenhouse gas emissions and secure our energy independence.
As a major clean energy contributor, U.S. hydropower plays an important role today for both electricity generation and energy storage. For more than 100 years, U.S. hydropower has been an important source of low-cost, low-emissions renewable energy.
This month marks the 40th anniversary of the Energy Department’s Weatherization Assistance Program (WAP), which provides funding to states, territories, and tribal governments to improve the energy efficiency of the homes of low-income families, persons with disabilities, and senior citizens.
The second round of the Small Business Vouchers program has wrapped up with 43 clean energy small businesses from across the United States being selected to connect with the top-notch scientists, engineers, and world-class facilities at the Energy Department national laboratories.
In order to understand how fish swim through rivers, Pacific Northwest National Laboratory (PNNL) has developed an injectable tracking device, known as an acoustic fish tag, with a self-charging battery. Funded by the Energy Department, this project is part of a long-term mission to contribute valuable research on fish migration through waterways when encountering hydroelectric dams. The key purpose of the study is to see whether or not fish become injured or hindered by the presence of hydroelectric devices.
Here are five things you likely didn't know about the Department of Energy’s Wind for Schools program, which helps to develop a wind energy workforce by educating students across the country on the value of wind energy and the bright future accessible through careers in wind.
The Energy Department is celebrating the 40th anniversary of the Weatherization Assistance Program, which has retrofitted more than 7 million homes across the U.S. and has led the nation in advancing technology, research, and applied scientific practices to make homes energy efficient.
This year's Geothermal Design Challenge tasked teams of high school and university students to research, design, and promote their infographics that answer the questions: What is the future of geothermal and how will it impact you?
A team of students from New York were recognized in Washington, D.C., as the winners of the first national run of the BioenergizeME Infographic Challenge, which provides high school students an opportunity to combine research, graphic design, and social media to learn about bioenergy and share their knowledge.
The Department of Energy’s SunShot Initiative funds cutting-edge science that helps dramatically reduce the cost of solar energy. Drawn from diverse inspiration in the optical and medical fields, and featuring one with new uses for sound waves, these newly announced SunShot research and development projects may hold the key to low-cost solar energy.
The U.S. Department of Energy’s Deputy Assistant Secretary for Energy Efficiency Kathleen Hogan recently toured the Intertek testing laboratory in Cortland, NY – one of the sites where the Office of Energy Efficiency and Renewable Energy (EERE) tests products to ensure that consumers are getting the savings promised by its federal Appliance and Equipment Standards Program. Total savings for Americans are currently estimated at more than $65 billion annually.
An Energy Department supported financing mechanism for energy efficiency and renewable energy improvements on private property is enabling state and local governments to fund the upfront cost of energy improvements, with those costs being paid back over a fixed period such as 20 years while energy expenses are reduced immediately.
The Co-Optimization of Fuels & Engines (Co-Optima) initiative aims to simultaneously transform both transportation fuels and vehicles in order to maximize performance and energy efficiency, minimize environmental impact, and accelerate widespread adoption of innovative combustion strategies.
The SunShot Initiative fosters innovation, challenging the recipients of our funding to bring next-generation technologies to the market in just a few years. These new technologies can give homeowners more choices for how they want to go solar while also having a major impact on cost and ease of installation.
After you’ve made the decision to go solar, the next step is figuring out how to pay for it. Assuming you don’t have the cash to buy your solar energy system upfront, like the vast majority of Americans, there are a variety of financing options to help you hitch onto the solar bandwagon and start increasing the value of your home.
Solar homes are being sold across the country, but they can be hard to find and compare. Teams from Lawrence Berkeley National Laboratory and Elevate Energy are working to ensure that solar is properly represented in multiple listing services, the searchable databases used by real estate professionals and house hunters.
Hydropower has been around for more than a century and is currently the nation's largest source of clean, domestic renewable electricity. Our new Hydropower Vision report explores how it could grow by 2050.
The amount of solar connected to the grid has grown exponentially in the past several years, and with all of this interest and so much information available, let’s take a moment to separate fact from fiction. The SunShot Initiative has debunked the top 5 myths about residential solar.
