Why does solar always need batteries? These are not "advances". India is adding 20k MW of solar and 10k MW of wind p.a. China is at 20+20. US at 20+20. Europe at 20+20.
30% of all new power capacity additions globally will be from renewables for the foreseeable future. Probably more.
This is without "batteries". Without subsidies.
The need for "baseload", "storage", or "the sun doesn't always shine and the wind doesn't always blow" are red herrings. They are not relevant.
Whether we like it or not, driven by massive cost and technology improvements, solar and wind are here in a massive way.
(1) Utility Scale Solar is already less <$1/W installed in India, and heading for sub $1.5/W in US.
(2) The price of Solar PV panels is already at $0.40/W. US-based $FSLR is has a roadmap to get to $0.25/W by 2019. In addition PV efficiency is increasing by 10% yoy. This is just from purely riding the 'industrial learning curve'. See [1].
(3) "Value deflation" is a policy issue that has a simple policy solution. As a tech that produces an intermittent product, but has high fixed-costs but zero-marginal costs - solar (like wind) should be financed (and paid for) via a fixed tariff (feed-in tariff or FiT). See [2]. This is how Solar is financed in the rest of the world outside the US. If 'value deflation actually became an issue - then my guess is that regulators in the US would step in (but one can never say with US regulators who tend to get captured by various lobby groups).
(4) Solar will account for 30% of all new capacity power additions going forward globally. This is happening - now. There is over 100,000MW installed globally already.
In addition - every time solar or wind comes up for discussion on HN or elsewhere, the same misconceptions and confusions about baseload, intermittency and costs arise.
To summarise the counter-points again:
(1) Renewables does not need to be base-load or compared to 'base-load'. 'Base-load' is spectrum not a point. See [3]
(2) There is a difference between intermittent and 'unplanned'. Planned vs unplanned is the main issue. Even nuclear has unplanned shut-downs - no tech has a 100% 'capacity factory' running 24/7 365 days. see [4]
(3) Renewables can get to 60-80% penetration via:
(a) increasing efficiencies (happening now)
(b) increasing energy storage efficiencies with declining prices (happening now)
(c) geographical grid-integration (happening slowly)
(d) more flexible software-led demand-side and supply-side management (happening). See [5]

Anyone who has a commercial rooftop solar installation and probably have a typical SMA SunnyBoy inverter box installed - will know what a massive difference this is.
Hope this team will be able to commercialise this quickly - and their respective employers enable and push this project through.
crypto = 5th Amendment. Locked safe analogy = search warrant. Thats their simple messaging.
Apple needs to do what they do best - market this brilliantly but simply.
A box for which they can't make an individual key, only a master-key (at great cost of man-hours).
