In a recent report, the SEIA tracked more than 7,000 MW of installed solar capacity (by U.S. businesses) across 35,000 projects. This data is up from 2,500MW and 7,000 projects in the 2017 report.
The following is a ranking of these businesses based on installed megawatt (MW) capacity. Wait till you see which company is #1.
6. Google 142.9 MW
In a blog post in June, Google’s director for operations, energy and location strategy, Neha Palmer, said the search giant’s “purchases of energy from sources like solar and wind once again matched our entire annual electricity consumption.“
Looking to the future, Google is getting involved with some large scale solar power projects.
In January 2019 the firm’s senior lead for energy and infrastructure, Amanda Corio, said it would buy the output of a number of new solar farms through a deal with the Tennessee Valley Authority.
This will amount to 413 MW of power from 1.6 million panels, Corio said.
5. Switch 179.0 MW
In 2016, data center firm Switch commenced construction of two solar power plants in Nevada.
They have a combined capacity of 179 MW and can power all of its data centers with renewable energy.
4. Walmart 208.9 MW
Walmart makes the SEIA’s top four with just under 209 MW of solar.
In October 2018, the retail giant announced it had entered into an agreement with SunPower that would see the renewable energy firm install solar power at two distribution centers and 19 stores in Illinois.
3. Target 242.4 MW
Target wants to source all of its electricity from renewables by the year 2030. The company is aiming to install rooftop solar panels at 500 of its locations by 2020.
Additionally, Target is installing charging stations for electric vehicles at more than 100 sites.
2. Amazon 329.8 MW
Second in the SEIA’s list is Amazon. The Seattle headquartered technology giant says its solar installations in the U.S. have offset the carbon dioxide equivalent of over 200 million miles of truck deliveries.
In total, the firm has 32 rooftop solar systems in the U.S.
1. Apple 393.3 MW
Top of the SEIA’s list is Apple.
The company’s headquarters in Cupertino, California, is powered by 100% renewable energy from “multiple sources”. These include an on-site, 17 MW rooftop solar installation and 4 MW of biogas fuel cells.
