Coal may be perceived to be low-tech, but it's still one of the cheapest ways to generate electricity (as long as the negative externalities like pollution from mining and burning are ignored).
Arguably, nuclear power is more high-tech and doesn't pollute the air, but it does generate nuclear waste and there is the risk of accidents.
Wind and solar are held up as the optimal energy source, but they will not be able to displace many coal and gas plants until the electricity storage problem is solved. How many batteries would be required to power New York City during a windless night?
