This is something a lot smart people even here on hackernews have been unable to get their head around. The speed of cost decrease in renewable based electricity and battery prices. Solar electricity is cheaper now than all fossil fuel based electricity in most of the world already. But its cost are still decreasing at about 10% a year. So electricity that costs $1 today will cost $0.25 or less in 10 years. Most of us have not seen this on our bills yet as renewable still are small percentage of the total as the percentage of renewable increases our bills should start decreasing as well. Currently Electric cars you can drive 18 miles compared ice cars 10 miles for a $1. It could be 40 miles in 5 years and 80 miles a $1 in 10. Without even any improvements in the electric car motors and lighter batteries which could push the mileage to 100~120 miles a $1. This is the reason I feel electric vehicles will be supply constrained rather than demand constrained in the next few years. And if current manufacturers are unwilling to sacrifice their ice vehicle cash cows now they will loose the market to the new entrants very very quickly. And with electric cars being less complex to manufacture we might see manufacturers outside of Japan, Eur and USA.
