Over the past couple of decades, many companies throughout the U.S. have made a strong effort to become more energy efficient in their everyday practices.

While most organizations don’t reveal their overall annual kWh consumption numbers, many companies proudly showcase how many green energy hours (energy generated from green energy sources) they are using each year along with other major programs and initiatives that put them at the forefront of a more energy efficient future.

Here is our list, ranked by overall company size, of the 100 most energy efficient companies in America and a look at some of the ways these organizations are reducing consumption costs and minimizing their environmental impact in the process.

1. Wal-Mart

Size: 2.2 million (world) 1.4 million (U.S)
Founded: 1962 in Rogers, Arkansas
Industry: Retail
Green kWh Used Per Year: 314,843,272

This major retailer utilizes alternative energy sources in order to make its operations greener and more energy efficient and focuses on using the least amount of energy possible in the construction of their new chain stores.

In addition to partnering with Bloom Energy to purchase green energy credits, the company also has their own on-site generation with the goal in mind to become 100 percent supplied by renewable energy.

What is perhaps most impressive about the retail-giant?s energy efficient efforts is that they have made efforts across the board. This means LED lighting, energy efficient appliances and solar panels directly on top of many stores. To date, the company has installed 105 megawatts of solar panels, or enough to power about 20,000 houses on the roofs of 327 stores and distribution centers. Plus, the company has plans in place to double that number by 2020.

How much energy is that in total? Enough to be the single biggest commercial solar generator in the country.
