Wal-Mart goes solar


Bentonville, Ark. -- Wal-Mart Stores, Inc. has installed eight solar photovoltaic (PV) arrays in Massachusetts.

The arrays contain almost 10,000 solar panels that Wal-Mart estimates will generate 2.8 million kilowatt hours (kWh) of energy every year, eliminating almost 1.5 billion tons of carbon dioxide emissions.

The discount giant recently committed to increase the production of renewable energy to 7 billion kWh globally every year by Dec. 2020, up 600% from 2010 levels. By 2020, Wal-Mart also plans to reduce the amount of energy required to run its buildings worldwide by 20% compared to 2010 levels.
