The knock knock joke is not tired as form! What rot!

My 7-year-old thought 'Europe who? No, you're a poo' was HILARIOUS.

> it breaks the rules of the game because Europe isn't anyone's first name.

Except people in mythology. Only a matter of time before someone bestows it on their child.

Also, there's no strict rule it has to be someone's name. It just has to be something you could feasibly say to announce yourself.

Knock knock.
Who's there?

M.I.B. -- it's a big horse who?
M.I.B. -- it's a big horse, I'm a Londoner, that I love London so... [you have to sing it to get it]

Indian Solar PV

I would be interested in a seeing a map of countries in the world where renewables are reported to be cost competitive with coal.

I'm thinking about the second order effects of cheap solar PV in India. I'm worried that if you are basically a community of peasant farmers you'll still struggle to afford a solar PV set up for your village and might end up having to wait for the cables to come by. Another issue for the Indians is that, IIRC, they have quite a lot of coal miners.

I'm predicting a move of energy intensive industrial processes towards the equator.

I think that's probably a really difficult thing to answer because the ways energy generation is subsidised are a bit obtuse.

There's clearly a bunch of direct subsidies like a cash grant for R&D or construction or for generation. But something like subsidy for R&D is difficult to translate into a per kwh cost because it depends on how many kwh are produced using the technology.

There are price support mechanisms like feed-in tarrifs or take or pay arrangements like the UK's Renewable Obligation Certficate or just a minimum price guarantee. Those have a second order effect in that they make your project less risky and so reduce your financing costs. You can provide indirect subsidies like a state guarantee or underwriting, or lend at state rates of interest, again reducing financing costs or you can subsidise the creation of shared infrastructure like a new port or a nuclear research lab.

Or the situation where a state suppored coal plant is buying coal from a state supported coal mine and transporting it over a state supported railway. It might be difficult to work out who is subsidising whom.

Then you get a bit less proximate and look at things like externalities for carbon taxes or who bears the cost of medical expenses for coal miners. Or coal miners are employed at good wages and so not requiring social security from energy consumers / tax payers.

A lot of that will be hidden in either great complexity or commercial secrecy or both.

Not saying it couldn't be done, or that someone couldn't do something that was 90% right but it's tricky.
