Intermittency: What It Is and Why It Matters in Renewable Energy and Tech

When we talk about intermittency, the uneven, unpredictable nature of power generation from sources like sunlight and wind. It's not a flaw—it's a fact of nature. Solar panels only make electricity when the sun shines. Wind turbines spin only when the wind blows. This unpredictability is what engineers and policymakers call variable generation, and it’s the biggest hurdle in switching from fossil fuels to clean energy. Without a steady flow of power, the grid can’t function safely. Imagine your lights flickering every time a cloud passes over. That’s the real-world impact of intermittency.

That’s why energy storage, systems like batteries that hold excess power for later use. Also known as grid storage, they’re the missing link between clean energy production and reliable consumption. When the sun is blazing and your solar panels are overproducing, the extra power doesn’t just disappear—it gets stored. Then, when the sun sets or the wind dies down, that stored energy flows back into the grid. Solar power, a major source of renewable energy in India and worldwide. It’s clean, scalable, and falling in price—but it’s also intermittent. The same goes for wind energy, another key player in India’s clean energy push. It’s powerful, but it’s not constant. You can’t control the weather, but you can plan for it. That’s where smart grids, demand shifting, and hybrid systems come in.

What you’ll find in this collection isn’t just theory. These articles show how real people are tackling intermittency every day—from how solar homes use batteries to avoid blackouts, to why biomass and hydropower sometimes create more problems than they solve. You’ll see how nanotechnology and AI are being used to predict energy patterns and optimize storage. You’ll learn what’s working, what’s not, and why sugar in soda matters more than nanoparticles when it comes to public health—because sometimes, the biggest threats aren’t the flashy ones.
