Despite serving a valuable purpose to us all, tech companies have been criticized for years for their exorbitant energy consumption. Data centers are the backbone of the internet and keeping all that information just a click away requires a lot of electricity.
A transition to renewable sources is underway, which cloud users can encourage by choosing their online service providers that source clean energy.
The ‘Dirty Cloud’
Data centers use up to 3 percent of all U.S. electricity and the information technology sector is responsible for 7 percent of global electricity consumption. The term “dirty cloud” was even coined to refer to the coal and other high-emissions fuel sources that power cloud computing. Global internet traffic has tripled in the last four years and it is anticipated to triple again by 2022, according to the International Energy Association.
The IT sector isn’t keeping up with its rapid growth,” says Gary Cook, the senior corporate campaigner on the Climate & Energy for Greenpeace. “More companies are making renewable energy commitments but energy demand growth by the industry is outstripping their renewable energy growth. This is an urgent issue to address the use of fossil fuels given the climate crisis.”
Since 2009, Greenpeace has been putting pressure on some of the more polluting tech companies while praising greener ones. When examining the energy footprint of tech companies, some clearly lead the way in the corporate use of renewable energy deployment, energy transparency, advocacy, and energy efficiency innovations.
Greening the Cloud with Renewable Energy

Every year, Americans dispose of billions of plastic bottles each year. On the surface, plastic bottle recycling in the United States looks like an excellent way to reduce waste and prevent the extraction of virgin materials. Curbside recycling programs span the United States and have become a staple in the waste management. In fact, plastic bottle recycling rates by weight have increased for the last 25 years consecutively. In 2014, the total weight of plastics collected for recycling grew by 3.3 percent or 97 million pounds. This seems like good news for the environment and our local cities and towns, but is it?
Although recycling programs are widespread, a mere 23 percent of disposable water bottles are actually recycled. While the weight of recycled plastic has grown for 25 years, so has the population in the United States. Here are three popular myths about recycling plastic bottles, along with an explanation of the real deal.

Did you know that Americans use 50 billion plastic water bottles each year, with a recycling rate of only 23%? From an environmental standpoint, it brings up numerous concerns. Kicking our bottled water habit can conserve resources, but what are we going to do with the billions of plastic bottles that are recycled? How do we boost stubbornly low plastic bottle recycling rates?
Luckily, Patagonia has been looking at this issue for decades and has made considerable progress in turning plastic trash into polyester fabric for apparel. The company has found a way to actually upcycle plastic bottles, finding a good use for this waste stream by turning it into a higher value goods.
In 1993, Patagonia produced the first polyester fleece jacket from recycled bottles. It had a green tint, from green soda bottles. Now, manufacturing waste, plastic bottles, and worn out clothing is recycled into new apparel, literally closing the recycling loop. Patagonia's product line has expanded from fleece jackets to include 82 products with recycled polyester, including insulated pants, down jackets, and beanies.
