Global energy transition
Significant global energy developments — technology, finance, supply chain and policy shifts that change the outlook for renewable energy in the Middle East and South Asia.
Arcnex Energy covers global energy news selectively. We report on developments that change costs, technology or policy direction for the Middle East and South Asia rather than attempting to cover every market.
That means module and battery pricing, cell and storage technology milestones, interest rates and project finance conditions, critical mineral supply, trade measures, COP outcomes, and the strategies of the international developers and utilities active in our core regions.

Policy & marketsThe Duck Curve and Curtailment: Solar's Success Problem
Solar reshapes demand into a curve that dips at midday and ramps at sunset. Why that causes curtailment and negative prices, and what fixes it.

Policy & marketsHow Renewable Energy Auctions Work, and How They Go Wrong
Competitive auctions drove renewable costs down worldwide. How they are designed, why some produce undeliverable tariffs, and what makes one good.
Read storyPolicy & marketsWhat Is a Power Purchase Agreement (PPA)?
The PPA decides whether a renewable project can be financed at all. The terms that matter, how risk is allocated, and why offtaker credit sets price.
Read storyPolicy & marketsWhat Is LCOE? The Number Behind Every Energy Cost Comparison
Levelised cost of energy makes generation technologies comparable, and hides things that matter. How it is calculated and where it misleads.

Energy insightsCapacity Factor Explained: Why 100 MW of Solar Is Not 100 MW
Capacity factor is the number that makes generation technologies comparable. What it measures, typical values, and the mistakes it prevents.

Energy insightsGreen, Blue and Grey Hydrogen: What the Colours Mean
Hydrogen is colourless; the labels describe how it was made and the carbon released. What separates each route, and why methane leakage matters.

Wind energyOnshore vs Offshore Wind: Cost, Resource, Floating
Offshore wind delivers stronger, steadier output at higher cost. How the two compare on resource, economics and access, and what floating changes.

Wind energyHow Wind Turbines Work, and Why Wind Speed Matters So Much
Turbine blades work like aircraft wings, and power rises with the cube of wind speed. What that means for siting, turbine size and economics.
Read storyPolicy & marketsHow Grid Batteries Make Money: Revenue Stacking Explained
A grid battery rarely earns enough from one source. The markets storage participates in, why revenue stacking matters, and how contracts shift risk.

Battery storageBattery Degradation and Cycle Life Explained
Batteries lose capacity through use and through time. How depth of discharge, temperature and charge rate affect life, and how to read a warranty.

Battery storageLong-Duration Energy Storage: Beyond Four Hours
Lithium handles hours. Balancing a renewable grid across days and seasons needs something else. The main technologies and their real prospects.
Read storyBattery storageSodium-Ion Batteries: The Case for Leaving Lithium Behind
Sodium is far more abundant than lithium and works the same way. What sodium-ion does well, where it falls short, and why storage is the target.
Read storyBattery storageLFP vs NMC Batteries: Why Grid Storage Chose LFP
EVs and grid batteries want different things from a cell. Why energy density decides one market, cycle life the other, and LFP won storage.
Read storyBattery storageHow Battery Energy Storage Works, From Cell to Grid
Grid batteries use the same cells as phones, arranged very differently. How a lithium-ion cell works, and what makes thousands a grid asset.

Solar energyString Inverters vs Microinverters vs Power Optimisers
Three ways to convert solar DC to AC, with very different behaviour under shade. How each handles a partly shaded roof, and which suits what.

Solar energySolar Trackers Explained: When Following the Sun Pays Off
Single-axis trackers lift annual output substantially, at the cost of moving parts. How they work, what they gain, and where fixed-tilt wins.
Read storySolar energyHow Long Do Solar Panels Last? Degradation Explained
Solar panels don't stop at 25 years, they gradually produce less. What degradation rates mean, how warranties work, and what shortens life.
Read storySolar energyBifacial Solar Panels: How Much Extra Energy?
Bifacial modules generate from both faces, but the gain depends on what is underneath. How albedo, mounting height and trackers decide it.
Read storySolar energyMonocrystalline vs Polycrystalline Solar Panels
The mono versus poly debate is settled, and the reason is manufacturing economics, not performance. What differs and what to compare instead.
Read storyEnergy insightsHow Do Solar Panels Work? The Photovoltaic Effect Explained
How sunlight becomes electricity: the photovoltaic effect, what doping and the p-n junction do, and why panels produce direct current.
