EBay, Apple, Samsung Austin Semiconductor and Sprint announced a joint agreement to purchase renewable energy.

The new project, called a virtual power purchase agreement (VPPA), will support Apex Clean Energy’s White Mesa Wind Project in Crockett County, Texas, and will generate 75 megawatts of clean energy, which is the equivalent energy needed to power 20,000 homes.

Collaborative renewable energy purchase agreements like this allow companies to pool their energy needs and collectively support large-scale renewable energy programs. The wind project is expected to come online in 2021 and will be developed by Apex Clean Energy.
