Everyone wants to know what the CHEAPEST way of producing electricity is.

We took on this mammoth task by aggregating reputable #LCOE reports and making a simple average 🤓

Our KEY findings 🧵 👇 1/ What is this LCOE? 🤔

It's a calculation of the dollar cost per unit of #energy ($/MWh) that a power station can achieve over its life span.

Except some institutions generalised it to cover a particular technology. @Lazard @WorldBank @IRENA @EIAgov @beisgovuk

Fact: ~HALF of the world does not have reliable internet 🤯

But this is changing at an unprecedented rate...

And may go down to nearly ZERO over the next two years as @elonmusk's network of internet satellites consolidates...

"Hello, world!" - Starlink🧵 1/ 40% of the world is OFFLINE 🌍

The internet is a cornerstone public infrastructure.

It's necessary for almost everything these days.
Communication, jobs, education, news, innovation...

There are virtually no analogue well-paid jobs left.

We've all been using cloud storage for many years, yet have no idea:
- What it can be used for 💡
- How it actually works ⚙️
- Its PROS and CONS ➕ ➖
- What platforms are available

A quick summary for you 🧵 1/ What's the cloud? ☁️

It's a network of computers, distributed across the world, capable of storing people's & organisation's data 📁
- documents 📄
- images 📷
- videos 📹
- websites 🌐

Each cloud provider has its own network of computers.

There are many providers ☁️☁️☁️

Did you know that 7% of global carbon emissions come from road #freight transportation? 🚚

And that @Tesla's Semi truck has almost 2x the range of its competitors?

A short🧵 on the up-and-coming disruption of trucking courtesy of @elonmusk Image 1/ Trucking needs disruption 🚚💥

7% of global carbon emissions come from road freight transportation, aka trucking.

This is comparable to that of the global aviation industry, and arguably much easier to #decarbonise.

Did you know that #wind can cause structures to resonate like guitar strings?

And did you know that this phenomenon can be used to harness #energy from the wind?

A short 🧵 on this alternative wind energy device 1/ Before we dive in, why is it even necessary to harness energy in alternative ways?

It's because turbines aren't optimal in ALL scenarios.
👉 Lack of space (e.g. cities)
👉 Turbulent winds (e.g. cities)
👉 Hard-to-adapt foundations (e.g. buildings)
👉 They're noisy

Do you have any idea how the internet works, or how it even started?

Or even, what the risks and rewards are of the up-and-coming web3 internet?

A short 🧵 to keep you up to speed on this crucial public infrastructure 🚠 1/ The origins 🕳️

Some say the OG was telegraphy, which allows us to share messages globally through electrical signals.

Others say it was the first network of local computers from the 1950s...

In any case, these pseudo-internets are certainly part of the recipe.

Did you know that only 60% of the global population has access to the #internet?

And that as English-speaking we're actually sheltered from most of the content?

A TL;DR thread introducing our long-form article, with data from @OurWorldInData🧵 1/ WE'RE #PRIVILEDGED

In the developed world, most people take internet access for granted.

But in some countries, internet users are still the minority 🤯

One of the big debates lately is over #nuclear energy.

Some say it's necessary for #NetZero by 2050.

Others say it's not net-positive for the #environment.

So are smaller reactors☢️a good alternative?🤝 Small Modular Reactors (#SMR )promise to bring a 'modular', more adaptable solution.

Build for a very specific purpose?
👉+1 SMR
Need to scale up for the grid?
👉+10 SMRs (SMR Farm)
Need to ramp down because #fusion finally arrived?
👉 -1 SMR per year

1/ With all the talk about France's latest law on mandatory #solar roofing of car parks above 80 spaces, we think it's time to start talking about other symbiotic solar relationships 👇🧵 2/ Although car parks and roof buildings are optimal unused space in urban areas, there is also the need for #offgrid electricity ⚡ in rural areas which often rely on diesel generators when solar 🌞 PV isn't available.
