The Strait of Hormuz oil shock has put ASX green energy shares firmly back in focus.
Oil is the reason why.
When crude prices spike, the whole energy sector moves with them.
Investors are now trying to work out who benefits and who suffers.
Let's take a look.

Why the oil price matters
The Strait of Hormuz carries a large slice of the world's seaborne crude.
Any disruption there ripples straight through global markets.
As a result of the most recent disruptions prices have remained elevated, even after cooling from their peaks.
The WTI crude oil price recently sat near US$78.93 a barrel. Brent was around US$84.31.
Higher oil prices lift the cost of fossil-fuel power. In theory, that improves the relative economics of renewables, as wind and solar don't burn fuel and their input costs don't rise when a tanker changes course.
That is the simple bull case, but the reality is a little more complicated.
What the latest oil shock means for ASX green energy shares
Most ASX green energy shares are not pure-play renewables businesses. Many still earn money from gas, coal, or electricity retailing. So the oil story cuts both ways. A higher wholesale power price can help earnings today. A faster energy transition can help earnings tomorrow.
Investors need to weigh each business on its own merits. Here are three names worth watching.
Three ASX green energy shares in focus
First up is Origin Energy Ltd (ASX: ORG).
Origin runs generation, gas, and a growing renewables and storage arm. The company is also one of the country's largest electricity retailers.
Origin shares have had a rough run of late. They recently fell around 19% from this year's highs, which traces back to its March quarter update in late April. This update showed declines across its Integrated Gas, Energy Markets, and Octopus Energy segments. Crucially, the company also downgraded its FY26 EBITDA guidance.
Today's share price weakness could interest bargain hunters.
Next is Meridian Energy Ltd (ASX: MEZ). Meridian is a New Zealand-based renewables generator built on hydro power.
Hydro provides roughly 60% of New Zealand's electricity, and the company recently won final approval to expand its Lake Pūkaki hydro storage.
However, dry-year supply risk, wholesale price uncertainty, and the drawn-out Lake Pūkaki storage approval process (contested by Transpower and the Energy Minister) all weighed on the shares over the year.
Finally, there is Infratil Ltd (ASX: IFT).
Infratil is an infrastructure investor with broad exposure.
Its portfolio spans renewable generation, data centres, and airports.
That diversification can smooth out the bumps across the current oil shock, giving investors a bit of downside protection.
The bottom line on ASX green energy shares
The Strait of Hormuz crisis is a stark reminder of the world's reliance on oil.
It also underlines the long-term case for cleaner power.
But ASX green energy shares are not a simple one-way bet. Each business carries its own mix of risks and rewards, and investors should be careful to analyse each opportunity individually.
Foolish takeaway
Oil shocks come and go.
The energy transition looks more like a multi-decade theme.
For patient investors, ASX green energy shares offer one way to play it.
Just be sure to understand what sits inside each business first.
