Recently, I was reviewing trends in the energy sector and I was surprised to see how much the renewable landscape has evolved. Investments in solar energy have grown almost exponentially over the past decade, and honestly, there are very solid reasons for it to continue this way.

First, the context: renewable energies now account for more than one-third of global financial assets. That’s not insignificant. And the most interesting thing is that historically, they have outperformed traditional funds while reducing volatility. Experts predict that in the next 30 years, more than two-thirds of global energy generation will come from renewables. That’s not a passing trend; it’s a structural transformation.

Solar energy in particular has a special appeal. McKinsey estimates that by 2035, renewables will generate 60% of the world’s electricity, with solar and wind leading the way. The cost of solar technology has plummeted in recent years, now being cheaper than fossil fuels in many countries thanks to subsidies and tax credits.

Looking at specific companies, the numbers are striking. JinkoSolar, Canadian Solar, First Solar, and other industry leaders have shown extraordinary profitability. Of course, there is volatility and strong competition, but the direction is clear.

In Spain especially, investing in solar energy makes sense. The country has 2,500 hours of sunlight per year and ambitious plans: to generate 74% of electricity from renewables by 2030 and 100% by 2050. Solar capacity will go from 13.2 GW in 2020 to an estimated 72 GW in 2030. Companies like Acciona, Grenergy, Solaria, and Soltec are positioned in this wave.

Now, if you’re considering investing in solar energy, you have options. You can buy direct shares of solar companies if you’re looking for long-term growth and dividends. Or you can diversify with clean energy ETFs like ICLN, which expose you to multiple players without concentrating risk in a single company.

Risks exist: dependence on weather, still-evolving technology, high initial capital requirements, storage costs. But the alternative is sticking with fossil fuels, which remain volatile and limited.

What catches my attention is that governments around the world are mobilizing massive resources. Europe plans 1 trillion euros in sustainable investments this decade. the U.S. committed 45 trillion for 2023. These are not small numbers. When so much institutional capital is moving in one direction, the momentum is real.

If you want to expose yourself to a sector with growth prospects spanning decades, with increasing structural demand and increasingly efficient technology, investing in solar energy remains one of the market’s most solid bets. It’s not speculation; it’s betting on where global energy is headed. And that makes a lot of sense.
