By The Numbers An EV requires an estimated 8 kWh of charge for every 25 miles. On Oahu, that 8 kWh per day can cost you about $82/month*.
*Based on $0.34/kWh
You might be thinking . . . $82/month is great, but I’m buying a brand new car! How can I really make it worth it? The answer is:
ZERO OUT YOUR USAGE WITH NEGAWATTS. THE NEGA-WHAT? A negawatt is energy that has been saved by getting rid of an energy-hogging device (like an old fridge) or by upgrading to a more energy-efficient technology. Think of it like a game – the more negawatts you create, the closer you get to zero!
Try these energy-efficient upgrades and offset the energy used to charge your EV:
EXAMPLE 1: Solar Water Heater ENERGY STAR® Fridge Install LEDs (2)
5.66 kWh 2.25 kWh 0.09 kWh 8.0 kWh
EXAMPLE 2: Solar Water Heater Upgrade Window AC Low-Flow Showerheads (2) Smart Power Strip
5.66 kWh 0.64 kWh 1.68 kWh 0.21 kWh 8.19 kWh
Remember, these are just examples.
The combination of energy conservation and efficiency measures you use in your home are entirely up to you! (Savings may vary based on usage and electric rates.)
