大賣場搞太陽能發電... WalMart來了.

利用賣場大面積屋頂來做可再生能源很適合, 因為她特別能教育與提醒大眾Renewable Energy的重要.. 這是地球公民的責任
WalMart說這只是個開始, 以後會擴及全美超過8000家分店.

• New solar panels installed at the proposed Walmart locations in California and Arizona will generate more than 22.5 kilowatt hours (kWh) of electricity each year
• The solar panels will offset 20-30% of the energy requirements of each retail outlet store
• The environmental impact will be the equivalent of taking over 3,000 cars off the road
