Google has made public new agreements to buy renewable energy to power its operations, according to an article in The New York Times. This will almost double its current green-energy promises.


The announcement was made amid debates and discussions to reduce carbon dioxide emissions at the U.N. conference on climate change in Paris in early December.


“We’re one step closer to our commitment to triple our purchases of renewable energy by 2025 and our goal of powering 100 percent of our operations with clean energy,” Google stated in a Dec. 3 post on the company’s official blog. “We hope that our efforts play a small part in boosting all of us in the race to solve climate change.”


This latest agreement will add 842 megawatts of renewable energy to power its data centers.


Google has already invested about $2.5 billion in renewable-energy projects. This newest deal will raise the 1.2 gigawatts (GW) of renewable energy it agreed to purchase to 2 GW. These projects include wind power farms in Oklahoma and Sweden as well as solar farms in Chile and North Carolina.


Google’s long-term contracts range from 10–20 years for wind and solar facilities. The company works with utility partners to promote green energy in that sector. In 2013, it created a program to allow customers to buy large amounts of renewable energy directly from utilities—and its latest announcement includes the first solar project enrolled in that program.


In 2015, there were several similar corporate purchases of renewable energy—some smaller than Google’s—including Amazon Web Services, Dow Chemical, Hewlett-Packard and Kaiser Permanente. Bloomberg agreed to buy more than 25 percent of the energy generated by a wind farm in Chautauqua County, N.Y., which will offset energy use of its New York offices, according to a company press release. Unilever also committed to eliminating coal from its energy makeup within five years.


Falling green energy prices and increasing pressure from shareholders and customers to produce direct action, instead of mere goals, to fight global warming prompted these green-energy deals, according to the Times article. New techniques such as a green tariff, which is being used in North Carolina and Nevada, make it easier for these companies to buy renewables through their utilities. Google helped to create the tariff. While these companies are merely buying offset credits, this investment could lead to further renewable-energy developments.
