Since January 2021, the U.S. Department of Energy’s Office of Energy Efficiency and Renewable Energy (EERE) has invested $1 billion in clean energy technologies. This astonishing total represents how EERE exercises its federal responsibility to protect, support, and provide for Americans, by investing in America to build a clean energy future for all. We do this by being good stewards of taxpayer dollars and investing in American-made clean energy innovations.

You have the right to know where that $1 billion is going.

That funding is helping transition the United States to 100% clean energy and mitigate the effects of climate change. Completing that transition will have a trickle-down effect that solves the biggest problems affecting Americans’ everyday lives. It will:

Icons representing savings, storage, zero emissions, justice, jobs
  • Save money and stress with more affordable electricity so Americans get the heating and cooling they need
  • Strengthen power system resilience, by providing backup through a greater mix of renewable energy resources and energy storage
  • Eliminate fossil-fuel emissions to improve human health and safety
  • Increase justice and equity, as communities plan the clean energy transitions that make the most sense for them
  • Create jobs to put individuals to work, build community wealth, and boost U.S. competitiveness

Every EERE technology office issues funding opportunities to solicit projects that address technical challenges in renewable energy, energy efficiency, and sustainable transportation. Here are just some of those investments that add up to this billion-dollar milestone:

Advanced Manufacturing Office (AMO)

AMO awarded $58 million to 30 projects to achieve cleaner, more efficient manufacturing and manufacturing processes for clean energy technologies.

AMO also awarded $60 million to university-based Industrial Assessment Centers, which help small- and medium-size manufacturers reduce their carbon emissions and lower energy costs, while training the next generation of energy-efficiency workers.

Bioenergy Technologies Office (BETO)

Together with AMO, BETO awarded over $13 million to seven projects that will convert plastic films into more valuable materials and design new plastics that are more recyclable and biodegradable.

BETO awarded $64 million to 22 projects to develop technologies and processes that produce low-cost, low-carbon biofuels to reduce transportation emissions.

Building Technologies Office (BTO)

BTO awarded $32 million to 30 next-generation building retrofit projects that will dramatically improve affordable housing technologies.

BTO also awarded $83 million to 44 projects that will lower Americans’ energy bills by investing in new energy-efficient building technologies, construction practices, and the U.S. buildings-sector workforce.

Geothermal Technologies Office (GTO)

GTO awarded $12 million to seven projects to research and develop technologies that can make geothermal systems more efficient for renewable energy production.

GTO also awarded over $8 million to four projects to establish new geothermal energy and heat production from abandoned oil and gas wells.

Hydrogen and Fuel Cell Technologies Office (HFTO)

Together with Vehicle Technologies Office, HFTO awarded $127 million to five vehicle manufacturers to improve medium- and heavy-duty truck efficiencies and reduce freight-transportation emissions.

HFTO also awarded $36 million to 19 projects to advance clean hydrogen production and fuel cell subsystems and components for heavy-duty applications.

Solar Energy Technologies Office (SETO)

SETO awarded $45 million to 12 projects to create a consortium on grid integration technology, give utilities better data about rooftop solar power generation, and advance commercialization of solar innovations.

SETO also awarded $40 million to 22 projects to advance perovskite photovoltaic devices, manufacturing, and performance validation.

Vehicle Technologies Office (VTO)

VTO awarded $60 million to 24 projects to reduce emissions from passenger cars and light- and heavy-duty trucks.

VTO also awarded $71 million to 20 projects to reduce emissions for on- and off-road vehicles and accelerate the expansion of electric vehicle infrastructure and charging.

Water Power Technologies Office (WPTO)

WPTO awarded $25 million to eight projects to advance wave energy technologies using open-water testing.

WPTO also awarded $8 million to three projects that improve the flexibility of the U.S. hydropower fleet and enhance electric grid reliability.

Weatherization Assistance Program (WAP)

WAP awarded $36.5 million to 21 organizations to prepare homes in historically disadvantaged communities for weatherization and electrification.

Wind Energy Technologies Office (WETO)

WETO awarded $13.5 million to five projects that will provide critical data to inform siting and permitting for offshore wind deployment while protecting wildlife and fisheries.


Now we’re kicking off fiscal year 2023, a new federal accounting cycle, and we’re keeping up the momentum by continuing to invest in our clean energy future. We will continue funding American innovators who research and develop groundbreaking ideas that will make the United States self-reliant on efficient, affordable renewable power. American-made innovations will take us where we need to be.
