Renewable energy comes from many sources - solar, wind and hydroelectric dams. But did you know it also comes from farms and food waste? That’s right! We’re turning farm and food waste into clean energy for consumers. It’s called renewable natural gas, and it’s making the world a better place by reducing emissions, producing clean energy and providing new income for family farmers. It’s also helping Dominion Energy achieve net zero greenhouse gas emissions by 2050.

How To Get Involved

Helping The Climate, Consumers And Family Farmers

Few clean energy sources can do so much good, so broadly across the economy. Here are some of the ways renewable natural gas is making the world a better place:

Fewer Emissions for the Climate

Renewable natural gas reduces greenhouse gas emissions from farms, food waste and landfills, which protects the climate and makes our air cleaner.

Clean Energy for Consumers

Renewable natural gas combines the environmental benefits of renewables with the reliability of natural gas to meet the 24/7 needs of our customers.

Income for Family Farmers

Renewable natural gas generates additional income for family farmers, turning one of their biggest costs into a new source of revenue.

Partnering With America’s Farmers

Renewable natural gas is a great technology, but we can’t do it alone. So, we’re teaming up with the nation’s largest pork and dairy producers to develop projects across the country. Once all of our projects are developed in the next 10 years, we will reduce annual greenhouse gas emissions in the U.S. by more than 5.5 million metric tons. That’s the same as taking 1.2 million cars off the road or planting more than 90 million new trees each year.

We’ve joined forces with Smithfield Foods to create Align RNG™. Together, we’re harnessing clean energy from hog farms across the U.S. Our first project is up and running in Utah and more are on the way.

Vanguard Renewables

We’ve teamed up with Vanguard Renewables to create clean energy from dairy farms across the U.S. Projects are underway in Georgia, Nevada and Colorado, with more planned nationwide.

Fewer Emissions For The Climate

Over the next 10 years, Dominion Energy’s renewable natural gas partnerships will reduce annual greenhouse gas emissions in the U.S. by the same amount as:

Cutting 5.5 Million Metric Tons of CO2e

Taking 1.2 Million Cars off the Road

Planting More Than 90 Million New Trees

How Does It Work?

When organic material decomposes, it produces methane, which is a powerful greenhouse gas. By keeping methane out of the atmosphere and turning it into clean energy, we’re helping to combat climate change. In fact, we capture more emissions from farms and food waste than are released when consumers use the gas. Better than zero-carbon, it’s actually carbon-beneficial! Here’s how it works:

Capturing Methane from the Farm


As manure, food waste and other organic material decomposes, it produces methane gas. Instead of allowing methane to enter the atmosphere, it's captured and turned into energy.

Converting Methane to RNG


The methane captured from farms, food waste and other sources is cleaned up to 99% pure methane, the same as traditional natural gas.

Delivering to Home and Businesses


Renewable natural gas is then blended into the existing gas distribution system to serve homes, businesses, power plants and other natural gas consumers.

How To Get Involved


Everyone can play in a role in protecting the environment and combating climate change. Our GreenThermSM program allows our Utah customers to voluntarily support the development of renewable natural gas projects. The program will soon be available in North Carolina, and with other states to follow.
