Stopped at the Walmart in Truth or Consequences, NM, for some supplies today. I thought how nice, new shades to avoid parking in the blazing summer sun. But these structures, eight of them covering the entire parking lot, are completely covered with solar panels. An associate said they were just installed and are supposed to power the entire store, once they finish with testing. Nice side benefit, shade in the 90 degree heat.
It's just a part of the big picture, but "...the biggest obstacle is public policy.":
Working toward 100% renewable energy
We’ve come a long way since our first on-site solar project in the U.S. in 2005 and our first large-scale wind power agreement in Mexico in 2006. At the end of 2013, we had more than 335 renewable energy projects in operation or under development across our global portfolio. These projects provide our facilities with more than 2.2 billion kilowatt hours (kWh) of renewable electricity annually. Together with renewable electricity from the grid, 24.2% of our electricity needs globally are supplied by renewable sources.
We recently committed to driving the production or procurement of 7 billion kWh of renewable energy globally by Dec. 31, 2020. We’re already 32% (2.25 billion kWh) of the way there. You can read about our approach to sourcing renewable energy.
