Just been looking at the iShares Global Clean Energy ETF and there's something interesting brewing here that most people might be sleeping on. The whole AI infrastructure buildout is creating this massive new demand for electricity, and it's changing how we should think about energy investments in 2026.

Here's the thing - Alphabet, Meta, Microsoft, and basically every major tech company are pouring hundreds of billions into AI data centers. These aren't just consuming chips and servers. They need power. Massive amounts of it. And that's where the green energy etf story gets interesting. Companies are literally restarting nuclear plants and making long-term electricity deals because the demand is insane.

The iShares Global Clean Energy ETF has been crushing it. Up 46.6% last year alone, and it's outperformed the S&P 500 and Nasdaq by a solid margin. That's not a fluke either. According to the latest International Energy Agency data, electricity demand is expected to jump at least 40% by 2035. And here's the kicker - 80% of the renewable capacity growth over the next five years is coming from solar. Solar's getting cheaper, easier to permit, and people actually accept it now.

What's making this green energy etf particularly compelling is the diversification angle. It's holding 102 different positions, but the top holdings tell you where the real opportunity is. Bloom Energy is sitting at over 10% - they're basically dominating the data center fuel cell space. First Solar, Nextpower, Iberdrola - these aren't speculative plays. They're actual infrastructure companies capitalizing on real demand.

I'll be honest though - the fund's expense ratio at 0.39% isn't exactly cheap, and concentration risk is real with the top five holdings representing 37% of the portfolio. But here's what caught my attention: the PE ratio is only 17.3 compared to the S&P 500 at 30. That's a pretty significant discount considering the tailwinds.

The policy environment got messier in 2025 with some federal support getting pulled back, but the underlying demand fundamentals are what matter. When you've got data centers needing massive amounts of electricity and solar becoming the default choice globally, that's a structural shift. Countries like Pakistan and South Africa are already deploying off-grid solar systems at scale.

If you're thinking about positioning for where energy demand is actually going, this green energy etf deserves a closer look. The AI power trade is real, and clean energy is becoming the backbone of it.
