Green Mountain Energy

We began in Vermont in 1997 with a simple but powerful mission: Use the power of consumer choice to change the way power is made. Today, we’re still 100% dedicated to protecting the environment, and we invite you to join us.

Our Business Structure

We sell cleaner electricity to both residential (home/condo/apartment) and commercial (business) customers.

Residential Products

We serve households in competitive markets in Illinois, Maryland, New York, Pennsylvania and Texas.

In traditional monopoly utility markets, Green Mountain partners with utilities who want to offer renewable energy products to their customers.

Outside of these areas, Green Mountain offers renewable energy certificates (RECs) and carbon offset products to help reduce the environmental impact of everyday activities like electricity use, driving and flying.

Commercial Products

Green Mountain is one of the premier retail providers of cost-competitive cleaner energy products to businesses and institutions in competitive electricity markets in Illinois, New Jersey, New York, Pennsylvania and Texas.

Nationwide, we offer innovative, customized sustainability solutions to commercial clients, including carbon offsets and RECs as well as consulting and assistance with green marketing strategy, corporate sustainability reporting and voluntary emissions reporting.

Environmental Governance

As a renewable energy, carbon offset and sustainability solutions provider, environmental sustainability is at the core of who we are, from the products we sell to the way we run our business. In particular, the following groups play a unique role in promoting environmentalism within the company:

Our Sustainability Department works with internal and external stakeholders to make sure Green Mountain is clean and green in all we do, including:

• Manage environmental claims, audits, and reporting to ensure the integrity of who we are and what we deliver to our customers
• Set an example of environmental excellence for employees, customers and other partners
• Share what we’ve learned with others by offering sustainability services and products
• Lead and grow Green Ambassadors employee sustainability team

Our all-volunteer employee sustainability team, the Green Ambassadors, includes 50+ employees company-wide who:

• Organize educational and service oriented activities to increase environmental awareness and action

Cleaner energy means a cleaner world. That’s the reason we exist. For more than 17 years, we’ve been using sun, wind and water to help protect the environment. In fact, we’re proud that our customers have enabled us to become the nation’s longest serving renewable energy retailer.
