Let's not forget that the push to clean up the atmosphere is leading the world down the path of developing electrically powered vehicles.
They're considered non-polluting (emissions) but producing the electrical energy they would need for battery charging will remain as dirty as ever until more renewable power can be generated. The electrical demands of smart-phones and computers is important of course but may be small by comparison.
I fear for the future of EV because the change from internal combustion engines will be huge and immensely expensive and there's no certainty how quickly it can be achieved on a large-enough scale. It's possible - perhaps more likely - that other vehicle power sources will be developed and hydrogen-powered engines are more likely to succeed in my view.
