T-Mobile has published its plans for achieving 100% renewable energy by 2021. These involve a combination of supply from two wind turbines (one in Oklahoma and one in Kansas (power generation is to commence in 2019) as well as purchasingelectricity from renewable energy resources to make up any shortfall in its ownproduction. In the same vein T-Mobile has also jointed RE100 (a network ofbusinesses that aims at tackling climate change through co-operation). 

 T-Mobile's announcement is not only great publicity for the business (being the first US wireless carrier to make this commitment is no mean feat!). It is also expected (if followed through) to save the business $100 million in the next 15 years.It will not only make investors and shareholders happy; it will help in the fight against climate change and hopefully spearhead other businesses towards doing the same.
