LCOE reflects:
- Capital (initial) costs 💵
- Maintenance and refuelling costs 🛠️
- Decommissioning ♻️
- Capacity Factor 🌞🌔 🕝
- etc.
To get rid of any bias, we took LCOE values from multiple reputable reports and averaged them out ➕ ➗
3/ The results 🥁
What was surprising?
👉 Onshore wind 🌄 is much cheaper than offshore wind 🌊
👉 Hydro and Geothermal can be very cheap too
👉 Gas, Biomass and Coal are cheaper than Nuclear ☢️ as baseload
👉 Concentrated Solar 🌞 has fallen behind $$$$
👉 Storage is $$$$
4/ Reality 🧂
The reality is that these results must be taken with a truckload of salt 🧂
And the case for building a new power station has to take a lot more into consideration 🤔
For example...
👉 LCOE calculations are inconsistent w/ each other
👉 We can't predict future fuel costs/interest rates/carbon tax
👉 Easy to fudge numbers and manipulate
👉 Subsidies and taxes over lifetime do change
👉 Innovation is FAST 🏃♂️
👉 There's financial effects outside producing ⚡
👉Polluting is likely to become very expensive 💨
👉Local resources vary (e.g. underground heat, wind, sun)
👉Grid re-balancing and new transmission costs
👉Baseload energy at peak time is more valuable
👉Nuclear Fusion could make this convo useless
5/ Conclusion 🤓
👉Cheapest doesn't mean most adequate.
👉Renewables have become very cheap 🤑
👉Be wary of authoratative claims on #Twitter based on LCOEs, its too easy to manipulate ❗
👉With so much uncertainty, best is to build a diversified low-carbon energy network ⚡

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 ☁️☁️☁️
2/ What are examples of cloud storage? ☁️📁
You've probably been using cloud storage for a while. For example:
- Google Drive (retail)
- DropBox (retail)
- OneDrive (retail)
- Amazon Web Services (Enterprise)
- iCloud (retail)
