Some of the world's biggest technology and telecommunications companies are still lagging behind in their use of renewable energy when compared to some of their closest peers. 

The United States Environmental Protection Agency (EPA) has listed the top 30 largest green power users among the tech and telco partners of the Green Power Partnership.

Even though Google, Digital Realty, Equinix, Dell, Rackspace US and Samsung are among the top 10 companies with the largest renewable - or green - power usage, all of them currently draw less than 50 per cent of their power from green sources.

However, Intel, Microsoft, Apple and Cisco currently use 100 per cent green energy sources to power their business.

According to a study by Technavio, the global green data centre market is expected to reach US$ 55 billion by 2021.

Here are the top 10 energy consumers operating in the US tech sector, according to the EPA, and how much power they draw from renewable sources:
