Shadowing Bill Gates

Summary

Bill Gates connects affordable energy with poverty reduction and argues that electricity production must move toward near-zero carbon emissions. He breaks emissions into population, services used, energy per service, and carbon released per unit of energy. In his account, rising living standards make efficiency alone insufficient, so major innovation in energy supply is essential. He compares several technological paths, describes a nuclear project he is backing, and calls for research, demonstrations, and incentives that make clean energy economically attractive.

Key points, in order

1. Gates argues that poorer communities face both the consequences of climate change and the burden of expensive energy. His desired outcome combines lower costs with dramatically lower emissions.
2. He considers fossil fuels with carbon capture, nuclear power, and renewable sources. Each faces different obstacles, including waste management, safety, land use, transmission, intermittent supply, or storage.
3. TerraPower serves as an example of a proposed breakthrough, using a traveling-wave reactor approach and material left from conventional uranium processing. Gates describes potential benefits while acknowledging unresolved development and demonstration challenges.
4. His proposed progress measures include immediate efficiency gains and advancement toward scalable zero-emission technology. The discussion afterward explores financing, deployment, other nuclear designs, and geoengineering as a possible emergency research option.

Five useful phrases to practise

Choose a caption line to open Repeat mode. Listen, then say it after the speaker.

1. 0:16 I'm going to talk today about energy and climate.
2. 5:06 Getting rid of poverty means providing these services to almost everyone on the planet.
3. 9:09 and we can't give up any of them because they look daunting, because they all have significant challenges.
4. 18:01 We need to go for more research funding.
5. 22:36 And it's best if multiple succeed, because then you could use a mix of these things.

What this talk trains

Bill Gates speaks for about 30 minutes: roughly 4,460 words in 343 caption lines. The pace picks up as the talk goes on, from about 157 words a minute in the first quarter to 173 in the last. Overall it is faster than 32 of the other 66 talks on Sada. Its sentences average 17.2 words, longer than the middle of the library (14.3), and 10.7% of its words fall outside the 3,000 most common English words (library middle: 12.9%). It asks 29 questions, so there is plenty of question intonation to copy. Phrases that fast speech often shortens come up again and again: “have to” (14 times) and “going to” (13 times).

Lines from across the talk, and what each one trains

One line from each quarter of the talk. Press a line to open it in Sada, ready to record. “Linking” marks words that run together: a word ending in a consonant sound joins the vowel that starts the next one.

1. 5:19 but every year, this number, on average, is going to go up,

   “going to”: fast speech often shortens it to “gonna” when a verb follows. Listen for whether the speaker does here. Linking: say “but every”, “on average” without a break between the words.

2. 12:38 Now, how are we going to go forward on this -- what's the right approach?

   “going to”: fast speech often shortens it to “gonna” when a verb follows. Listen for whether the speaker does here. A question: listen to where the voice rises or falls at the end, and copy it.

3. 19:57 and then the process starts at the top and kind of works down?

   “kind of”: fast speech often shortens it to “kinda”. Listen for whether the speaker does here. A question: listen to where the voice rises or falls at the end, and copy it.

4. 24:58 Are they saying there's negative feedback effects that have to do with clouds that offset things?

   “have to”: fast speech often shortens it to “hafta” when a verb follows. Listen for whether the speaker does here. A question: listen to where the voice rises or falls at the end, and copy it.

Words that keep coming up

Words outside the 3,000 most common English words that Bill Gates uses more than once. The number is how often each is said. Look up any you don’t know, then press it to practise the line where it first comes up.

• reactor ×10
• miracle ×9
• burn ×7
• hundred ×7
• climate ×5
• constraint ×5
• burning ×5
• innovation ×5

How the pace changes through the talk

The fastest minute starts at 26:09 (about 205 words a minute): practise that minute once the rest feels easy. The slowest starts at 18:09 (about 107): a good minute to warm up with.

Measured from the caption timing, so the numbers are close, not exact.

How the talk opens: press any line to practise it

1. 0:16 I'm going to talk today about energy and climate.
2. 0:20 And that might seem a bit surprising, because my full-time work at the foundation is mostly about vaccines and seeds,
3. 0:27 about the things that we need to invent and deliver to help the poorest two billion live better lives.
4. 0:35 But energy and climate are extremely important to these people;
5. 0:40 in fact, more important than to anyone else on the planet.
6. 0:45 The climate getting worse means that many years, their crops won't grow:

How to practise this talk

1. Warm up on the slowest minute (from 18:09) or on the opening lines above.
2. Then take the chosen lines above one at a time: a shortened phrase, linked words, a question.
3. On each line, press Record and say it after Bill Gates (Repeat) or along with them (Shadow), then open Compare and go again until every word is green.
4. Save the fastest minute (from 26:09, about 205 words a minute) for last.
5. At one minute a day you finish the whole talk in about 30 days, and Sada shows your first try against your latest.
