30c per litre. That's Wonderful!

New Zealand is perfect for electric vehicles. More than 80% of our country’s electricity generation is clean, green and renewable. And it costs the equivalent of 30c per litre. 
Electric transport could help reduce our nation’s reliance on expensive imported fossil fuels, and help you save at the same time. That’s energy freedom, and we think it’s wonderful!
