Image of the Day: Green Onion Takes on New Meaning
Gills Onions is a food processing company in California that already sets an energy example by using its own waste to generate electricity. But recently, after repeatedly needing to purchase additional electricty at the most expensive time of day, the company became even greener by adding a gigantic battery.
According to The New York Times, the battery is the same in principle as many others except it has external tanks to store huge volumes of electrolyte and takes up a space the size of a tennis court, making it the largest of its kind in the world. In addition to enabling the company to pay off-peak electricity prices, it provides energy security by stepping in during the event of a power emergency.
