Fastest Growing Energy Source
Why Solar is the Fastest-Growing Energy Source
(and Why Even Big Utility Companies Are Investing)
Solar energy is no longer just a buzzword—it’s officially the fastest-growing source of electricity in the world. ☀️
👉🏻In fact, solar added more power to the global grid in 2024 than any other energy source, outpacing wind, gas, and coal combined.
🏡 For homeowners, that’s great news: the same trend fueling global adoption is also helping make solar power more affordable and accessible than ever.
‼️But what’s more surprising is that major utility companies—once resistant to renewables—are now investing billions into solar farms. The shift signals a permanent change in how our electricity will be produced and priced for decades to come. ⚡️
According to Ember’s Global Electricity Review 2025, solar generation grew nearly 29% year over year, doubling global capacity from 1 terawatt (TW) in 2022 to 2 TW in 2024.
Why Solar is Growing Faster Than Any Other Energy Source
The growth of solar power is driven by a perfect storm of economics, technology, and policy.⚡️
First, costs have plummeted. Over the last decade, the price of solar panels has dropped by more than 80%, with PV module costs falling nearly 50% between late 2022 and 2023 alone (AP News). The International Energy Agency even declared solar “the cheapest source of electricity in history” in many markets.
Second, policies are encouraging rapid adoption. Federal programs like the 30% Investment Tax Credit (ITC) in the U.S. and various state-level incentives have fueled growth for homeowners and utility-scale projects alike.
Third, solar can be deployed faster than any other new power source. Large solar farms can be built and online within months, unlike natural gas plants or wind farms, which can take years due to complex permitting and construction timelines. That speed makes solar incredibly attractive as demand for clean power surges.
Utility Companies are Pouring Money into Solar
It might seem ironic: the same power companies that sell you electricity at rising rates—are now some of the biggest solar developers in the country.☀️
Why?
Because solar is now one of the most profitable and scalable ways for them to generate power. 🔌
These companies aren’t just meeting state renewable mandates—they’re seizing an opportunity. Solar allows them to stabilize long-term generation costs, meet corporate sustainability targets, and compete with private solar developers entering the market.
Big Corporations are Joining In
It’s not just the utilities making moves. Some of the world’s largest companies—like Amazon, Microsoft, Meta (Facebook), and Walmart—are signing contracts for or directly investing in solar farms to power their operations.
• Amazon now supports more than 600 solar and wind projects worldwide, making it the largest corporate buyer of renewable energy globally.
• Meta recently partnered on a 600 MW solar project in Texas, with Enbridge investing nearly $900 million in the project (Reuters).
• Walmart and Microsoft are expanding community solar programs to cut energy costs for stores and data centers.
These investments not only lower their carbon footprint but also lock in cheaper, predictable energy costs—advantages that traditional fossil fuel sources can’t offer.
What This Means for the Future
(And for you)
The numbers speak for themselves: solar accounted for 43% of global clean electricity generation in the first half of 2025, with growth outpacing every other energy source (Reuters). And with more utilities and corporations backing solar, the infrastructure to deliver cleaner, cheaper energy to homes is growing faster than ever.
For homeowners, this trend means:
• Lower solar installation costs (thanks to economies of scale and falling panel prices).
• More community solar and PPA (Power Purchase Agreement) options for those who don’t want to buy panels.
• Stabilized or reduced electricity rates as utilities shift to cheaper generation.
Whether you’re looking to install panels on your roof or just want lower, more predictable power bills, solar’s growth is reshaping the market—and putting pressure on traditional utilities to keep rates competitive.
