What are the tipping points discussed in the answer below? 

MH: And now we're seeing a similar picture for clean electricity? 

SS: Yes, we very much see the same thing happening in the power sector. And, in fact, there's not just one but a series of tipping points.

I would say that the first one was when new solar and wind power became cheaper than new coal and gas power – and that's already in the rear-view mirror. That's the case in the vast majority of countries in the world.

A second one that we're already beginning to pass now is new solar and wind generation becoming cheaper than existing fossil fuel generation. So, in other words, it's cheaper to build a solar or a wind plant than it is to keep shovelling coal into a coal power station or piping gas into a gas power station.

A third tipping point, which we're coming up towards, is when renewables plus energy storage become cheaper than coal and gas power. There's a piece of analysis from researchers at Exeter University which predicts that by the end of this decade, solar power plus storage will be half the cost of coal in big markets, in the EU, China, India, Japan, the US. So actually, we'll cross that tipping point really soon in the next few years.
