In one small way we've have tried to light one candle instead of curse the darkness. I created a three ring binder with several pages from various sources. In there is a picture of Phoenix with the mountains almost totally obscured by smog. On another I have a picture of our PV array that is tied to the grid so no matter where I am, I am putting more energy into the grid than I'm using to charge my car. There is another page with quotes from John Hofmeister, former President of Shell Oil, from his book, Why We Hate the Oil Companies. He really is for renewables in the long run. There is are several other pages that just support what I tell the people that are interested.
We have displayed our LEAF at several gatherings. Last April we displayed it and handed out reprints of some of the pages at the Phoenix Earth Day Festival. When a new General Store opened up near our summer home outside of Show Low, AZ, we displayed it there twice. One of the times the Humane Society was there looking for people to donate to help keep their shelter open. I made arrangements with the people that for anyone who would donate to their cause, I would give them a ride in our LEAF to experience the quiet ride.
The point is that anyone who has had a LEAF for any period of time and is willing to do a little internet work can do something similar. Yes, there are some close-minded people, but the majority have appreciated knowing about this new vehicle and EVs in general. Thus, I've probably enlightened a couple hundred people and what I hope is that those people when they get into a discussion about EVs that they will think that they are the expert and can relay their experience and knowledge to others. Word of mouth does work.
