Funny how the POTUS praising Walmart to Solar panels yet a few years ago when Administration funded a company named Solindra with tax payer money and it went belly up after the same POTUS visited it. With any luck this Walmart will Close and that would be a good thing since it is the worst I have been to. FYI most solar panels are made in China at a cheeper price.
Walmart-China match made in heaven.

"The company expects to save $1 billion."
Would those savings then be used to increase the wages of their workers? Can the money saved be used to pay for their worker's health care costs which is currently being absorbed by us, taxpayers? I did not hear or see mention that WMT cared about their employees. Wal-Mart also doesn't care about the environment. Professor Robert Reich can tell you that also. Web Link
WMT only cares about saving money for their board and top shareholders. Obama could have gone to Foothill College to show off solar panel installation. He mentioned community colleges in his speech but no mention about the rising costs of tuition.
