Energy Minerals Observatory: The data deficits in critical supply chains

Energy Minerals Observatory: The data deficits in critical supply chains

Critical minerals, such as copper, cobalt, and silicon, are vital for energy technologies, but most critical minerals markets are less transparent than mature energy markets, such as crude oil or coal. Like other energy markets, many supply-side and demand-side factors influence pricing for these energy-relevant critical minerals, but critical minerals supply chains contain numerous data gaps.

Spark and dark spreads indicate improved profitability of natural gas, coal power plants

Spark and dark spreads indicate improved profitability of natural gas, coal power plants

Higher average daily wholesale electricity prices between January and November 2025 may be improving the operational competitiveness of some natural gas- and coal-fired generators in the PJM Interconnection compared with the same period in 2024. PJM is the largest wholesale electricity market in the United States. The spark and dark spreads, common metrics for estimating the profitability of natural gas- and coal-fired electric generators, have both increased over the past two years.

Geopolitical developments contribute to elevated diesel prices

Geopolitical developments contribute to elevated diesel prices

Global refinery margins for diesel have widened since late October and increased to their highest level all year, following refinery outages in Russia and in the Middle East and new sanctions on Russia's crude oil, leading to limited refinery production and a decreased global diesel supply. The impact was most pronounced in the Atlantic Basin, contributing to higher prices at the Amsterdam, Rotterdam, Antwerp (ARA) shipping hub, a key benchmark for European prices, as well as at New York Harbor and the U.S. Gulf Coast. The higher global prices also affected prices in the United States because U.S. refiners can sell into both domestic and international markets.

Hurricanes in 2024 led to the most hours without power in the United States in 10 years

U.S. electricity customers experienced an average of 11 hours of electricity interruptions in 2024, or nearly twice as many as the annual average experienced in the decade before, according to our Electric Power Annual 2024 report. Major events such as Hurricanes Beryl, Helene, and Milton accounted for 80% of the hours without electricity in 2024.

To set up Appium on your notebook, you’ll need to meet the following requirements:

Operating System:
- Appium supports macOS, Linux, and Windows operating systems. Ensure your notebook runs one of these.
Node.js and NPM:
- Install Node.js (version in the SemVer range ^14.17.0 || ^16.13.0 || >=18.0.0).
- NPM (Node Package Manager) is usually bundled with Node.js, but you can upgrade it independently. Make sure your NPM version is >= 8.
Appium Installation:
- Install Appium globally using NPM:
```
npm install -g appium
```
Appium Server:
- Start the Appium server by running:
```
appium
```
- If you see output like “[Appium] Welcome to Appium v2.0.0,” the server is up and running ¹ ².
Additional Dependencies:
- To automate a specific platform (e.g., Android or iOS), refer to the documentation of the corresponding Appium driver(s) for any additional dependencies.
- Typically, you’ll need the developer toolchain and SDKs specific to the platform you’re testing ¹.

Remember to adapt the installation steps to your specific environment. Happy testing! 🚀📱

The disk space requirements for installing Appium, Node.js, and npm are relatively modest:

Appium:
- By itself, Appium is lightweight and doesn’t have significant disk space requirements.
- It can even run in resource-constrained environments like Raspberry Pi, as long as Node.js is available.
- No specific disk space quota is needed for Appium alone.
Node.js and npm:
- Node.js and npm are essential for running Appium.
- The installation of Node.js and npm doesn’t consume much disk space.
- However, ensure you have enough space for other development tools and dependencies.

In summary, a few gigabytes of free space should suffice for installing Appium, Node.js, and npm on your notebook. Happy testing! 🚀📱
