Coding classes in Arklow

What is the best coding class in Arklow?

Arklow has 13,316 usual residents, and most of its households are on broadband, which is all a live lesson from us needs. A teacher works on video with a small group at one level, or with one learner, about twice a week, for anyone from six to sixty-seven. Monthly fees are in US dollars: USD 100 for a group place and USD 150 for private lessons, after a free first lesson.

Off the coast from Arklow, SSE Renewables is developing Arklow Bank Wind Park 2, and its web page makes two large claims: that the wind farm would power 834,286 homes, and that it would abate 826,944,000 kilos of carbon emissions a year. Unusually, and to its credit, it prints a footnote showing how both were worked out. That makes them checkable. The learner rebuilds each figure step by step, writing every number with its unit. The homes figure reproduces exactly. The carbon figure reproduces too, but only once a unit printed in the footnote is read as kilograms rather than grams, a factor of a thousand that nobody notices by reading and everybody notices by calculating.

Signature project

Check the wind farm's arithmetic, units and all

SSE Renewables states its assumptions in a footnote: 800 megawatts of capacity, a wind load factor of 50 percent and 4,200 kilowatt-hours a year for a typical home. The learner rebuilds the homes figure from those three numbers.

Rebuilding the homes figure, one unit at a time
StepUnitValue
Proposed installed capacitymegawatts800
Hours in a 365-day yearhours8,760

The same energy in kilowatt-hourskilowatt-hours3,504,000,000
Divided by 4,200 kWh per homehomes834,286

Power is not energy

A megawatt measures how fast energy is produced; a megawatt-hour measures how much. Multiplying by hours turns one into the other, and it is the step most often skipped when a capacity is quoted as if it were an output.

It reproduces exactly

The rebuild lands on 834,286, the footnote's own figure, to the last home. That also reveals a detail the footnote leaves out: a 365-day year was used. With the 8,784 hours of a leap year the answer would be 836,571.

The assumption carries the claim

Change the load factor and the homes move with it: 667,429 at 40 percent, 584,000 at 35. This page does not say which figure is right. It notes that a claim which states its assumption is one a reader can test, which is exactly why this one can be checked at all.

The carbon figure, with the unit as printed and as the arithmetic needs it
Rate usedResult for 3,504,000,000 kWh

0.236 kilograms per kWh, which is 236 grams826,944,000 kilograms
Total quoted in the footnote826,944,000 kilos

Carry the unit through every step and a slip has nowhere to hide

The footnote prints the emissions rate as 0.236 grams per kilowatt-hour. At that rate the answer is 826,944 kilograms, a thousand times smaller than the total the footnote quotes. The quoted total matches 0.236 kilograms per kilowatt-hour, which is 236 grams, and the Commission for Regulation of Utilities reports the all-island average in grams per kilowatt-hour on exactly that scale: 258 in 2021 and 234 in 2022. So the arithmetic is consistent and the label beside the rate is the slip. Reading the footnote will not find it. Writing every number with its unit, and multiplying the units along with the numbers, finds it immediately.

In code, the learner stores each quantity as a value with a unit attached and writes three small rules: power times time gives energy, a thousand kilowatt-hours make a megawatt-hour, and a thousand grams make a kilogram. Anything else, such as adding a power to an energy, stops the program with an error. Fed the footnote's inputs, the program prints 834,286 homes, and fed the printed emissions rate it prints a carbon total whose unit and size cannot both match the quoted one. The follow-up is to write a one-line note to the publisher that points out the label politely, with the calculation attached.

Reading a big number

What the headline figures do and do not say

A reproduced number is a checked calculation, not a checked outcome. Three things are worth keeping in view.

Homes over a year

The homes figure is a year's energy divided by a typical home's yearly use. It says nothing about any particular hour; wind varies, and the calculation averages that away by design.

A proposal, not a power station

SSE describes a proposed capacity of 800MW from between 47 and 56 turbines, with construction that could begin towards the end of the decade if consented, and a maintenance base with around 80 full-time local jobs at Arklow Harbour's South Dock.

A moving comparison

Carbon abated depends on the grid it displaces, and that grid is changing: the all-island average fell from 258 to 234 grams per kilowatt-hour between 2021 and 2022. Any carbon figure is tied to the year of the rate it uses.

What this page does not claim

It does not judge whether a 50 percent load factor is realistic, whether the project will be built, or anything about SSE beyond the arithmetic on its own page, where the unit printed beside one rate does not match the total it produces. Neither SSE nor the CRU has any connection with us.

Learning here

Lessons for Arklow learners

Two regular lessons in most weeks, with the teacher there live throughout.

Children

Children aged six to twelve begin with blocks, games and animations, and meet units early: a sprite that moves ten steps a second is a rate, not a distance.

Teenagers

Arklow's 1,206 young people aged thirteen to eighteen are the age for Python, building websites, AI projects and data analysis that runs on real figures like the ones on this page.

Adults

Adults come in at every level, from none upwards. The first lesson places them and the course is shaped from there.

Census numbers on this page are taken unchanged from the Central Statistics Office. The wind farm figures are quoted from SSE Renewables' own project page and rebuilt on 19 September 2026; the grid averages are from the CRU's Fuel Mix Disclosure and CO2 Emissions report for 2022. Irish Rail is quoted from its station page.

Ask an assistant to check the footnote

It can do the sums. Whether it notices the unit depends on how it is asked.

An AI assistant given the footnote and asked whether the figures add up may multiply 3,504,000,000 by 0.236 and declare the total confirmed, carrying the number across and never the unit. The result looks like verification. It is a number check that skipped the one step where the discrepancy lives.

A learner who has done this project asks for the calculation with units written at every line, then reads the units first and the numbers second. The label shows up straight away, and the question for the assistant becomes a better one: which of the two, the rate or the total, carries the wrong unit.

An assistant is a fast calculator. Insisting that every number keeps its unit is still up to the person asking. The longer argument is in why coding is worth learning even now.

FAQ

Arklow coding class questions

The questions Arklow families ask most.

How many people live in Arklow?

The Census 2022 small area tables put Arklow's usual residents at 13,316, in 5,012 households, and 4,079 of those households have broadband.

What is the data project on this page?

Rebuilding the published arithmetic for Arklow Bank Wind Park 2 with units attached. The homes figure, 834,286, reproduces exactly from 800MW, a 50 percent load factor and 4,200 kWh per home; the carbon figure, 826,944,000 kilos, reproduces only with the emissions rate read in kilograms rather than the grams printed.

Is the wind farm's carbon figure wrong?

The total is consistent with a rate of 236 grams per kilowatt-hour, which is the scale the CRU reports. The unit printed beside the rate in the footnote is the part that does not fit. This page checks arithmetic only; it does not assess the project.

How do Arklow residents get to work?

Of 5,498 working residents in the travel table, 3,119 drive, 636 walk, 439 work mainly at or from home, 379 use a van, 327 go as a car passenger and 118 by bus.

When are lessons?

After school, in the evenings and at weekends. The clocks differ by four and a half hours in the Irish summer and five and a half in winter, India being ahead, so the slots offered are Irish afternoons and evenings that fall at sensible hours for teachers there.

Can adults take part?

Yes, up to sixty-seven, starting from any point. Whether an adult learns with a small group at the same level or with a private teacher is decided in the first lesson, from what they already know.

Are Arklow learners taught together?

Not necessarily. Groups are made by level, so an Arklow learner could share lessons with others in Wicklow, Wexford or another country.

Is there a Modern Age Coders classroom in Arklow?

No, and we never imply one. Teaching is live over video only, with no premises in Ireland. A learner needs a laptop or desktop, working sound and a steady connection, and the number shown here belongs to India.

What do coding classes in Arklow cost?

The first lesson is free. After that a shared place costs USD 100 a month and brings two live lessons a week, about eight monthly, with five to ten learners; one to one on the same schedule is USD 150 a month. Everything is agreed before payment.

How many learners are in a group?

Five to ten, grouped by ability, pace and goal rather than age or address. Where nothing suitable meets at a workable hour, we teach one to one instead.
