Cleantech companies are in the business of solving real problems—energy access, emissions, grid resilience. So when it comes to social media, it’s fair to ask: do platforms built for likes and trends really help you reach the people who matter? Take Instagram. It’s fast-moving, eye-catching, and massively popular. But popularity doesn’t always equal effectiveness. For cleantech, the question isn’t just “Should we be on Instagram?” The real question is: Does Instagram reach the audience you need to influence? Let’s unpack that. 1. Who’s on Instagram—and Is It Your Audience? Understanding Instagram’s demographics is step one. You need to know who you’re talking to before deciding if it’s worth talking there at all. As of January 2024, 62.4% of Instagram users are aged 18 to 34 . Of those, the largest cohort is 18 to 24, making up over 30% of the platform’s global user base. If your sustainable product is consumer-facing—e-bikes, reusable containers, EVs, energy-efficient electronics, or thrifted apparel—this is a receptive audience. But for deep tech firms, that’s a red flag. If your targets are city energy planners, commercial real estate developers, or utilities, they likely aren’t scrolling Reels between meetings. LinkedIn, by contrast, is the platform of choice for professionals and executives, especially in industries like energy, engineering, and infrastructure. According to LinkedIn’s own marketing solutions data , 4 out of 5 members drive business decisions, and over 58 million companies are represented. Instagram might help shape brand awareness—but it’s LinkedIn that wins when you're selling to decision-makers. 2. Instagram Is Visual. That’s Not Always an Advantage. There’s no doubt: Instagram is a visual-first platform. But being visual doesn’t automatically mean it’s a good fit for cleantech. To succeed on Instagram, your content needs to stop the scroll. That means clear, engaging visuals, preferably video. And right now, the most effective format by far is Reels , which generate over 200 billion plays per day. But Reels favor: • Personal stories • Fast cuts • Relatable or entertaining content That makes them ideal for a solar company with choreographed installers set to music. But not so ideal for a grid-tech startup explaining load balancing or smart inverters. Even the average time users spend watching Reels supports this. According to a Q1 2025 Meta report, the average watch time on Reels dropped to 5.2 seconds per clip. There are goldfish with longer attention spans than Gen Z. If you can’t boil down your bite-sized how to’s tips or “Did You Know?” message into 15 to 30 seconds of visuals—without losing technical accuracy—Instagram will not carry your message effectively. 3. B2B Buyers Want Aesthetics + Depth Most cleantech businesses sell to sophisticated buyers: developers, facility managers, compliance officers, procurement professionals, municipalities. As we’ve written repeatedly, B2B buyers are also persuaded by dopamine hits to the limbic brain that light up with visuals and stories. However, that’s just the beginning of the buyer’s journey. Once they enter your sales funnel, they need: • Technical specs • Case studies • Regulatory alignment • Cost-benefit breakdowns That doesn’t fit on a Reel. According to Demand Gen Report’s 2024 Content Preferences Study , 71% of B2B buyers read between three to five pieces of content before engaging with a sales rep. And those pieces are overwhelmingly whitepapers, in-depth articles, and product comparison guides. Instagram doesn’t support that kind of content—not in structure, not in length, and not in mindset. Use Instagram to humanize your brand, but don’t expect it to build a buying case. 4. YouTube and LinkedIn Deliver More Value Per Dollar If your content is visual and educational, YouTube is far more valuable than Instagram. YouTube reaches more U.S. adults each day than any other social platform , and it’s the second most-used search engine after Google itself. Cleantech companies that invest in high-quality explainer videos, site walkthroughs, or animated tech breakdowns see returns not just in views—but in actual conversions from engaged prospects. LinkedIn, meanwhile, lets you connect with: • Policy stakeholders • Investors • Industry associations • Fortune 1000 buyers And their lead conversion rates are 3X higher than other platforms , per LinkedIn Marketing Solutions. Your Instagram post may get 500 likes. But your LinkedIn whitepaper might land you a 7-figure pilot deal. 5. Instagram Is Not Pointless—But It’s Not Primary All that said, Instagram isn’t useless. It plays a role in your brand stack—just not the lead role. Use it to: • Showcase your team and company culture • Recruit younger talent • Celebrate funding milestones or awards • Promote sustainability stories that are emotional and human This kind of content builds trust and familiarity, which can influence how your brand is perceived elsewhere. But if your internal team is spending hours trying to squeeze an inverter spec sheet into a swipe carousel? You’re wasting time. 6. Use This Framework to Decide Use Instagram if: • Your product is visual, simple, and emotionally resonant • Your buyer is under 35 and likely to discover you via mobile • You have the in-house design or video chops to post high-quality content 2–3x a week • You can afford for it to be top-of-funnel only (awareness, not lead gen) Avoid Instagram if: • Your product is complex or regulatory-heavy • You sell primarily to other businesses or government • You’re trying to push thought leadership or in-depth content • Your team doesn’t have the bandwidth to regularly post original content This isn’t about shunning a platform—it’s about being selective. 7. The Real Cost of Chasing the Wrong Channel Every hour your team spends filming a time-lapse or tweaking a caption is time not spent writing a technical blog, creating an RFP response, or following up with a lead. Instagram is seductive. It’s fast and makes you feel busy. But likes don’t pay the bills. What does? Being where your buyer is. And more often than not in cleantech, that’s LinkedIn, Google Search, conferences, or directly in their inbox. Final Thoughts Instagram may be one of the biggest platforms on the planet, but that doesn’t make it right for everyone—especially in cleantech. If your audience is young, visual, and looking to be inspired, Instagram can build brand equity and tell powerful stories. But if your goal is to move complex, infrastructure-grade technology into the hands of cities, businesses, and builders, you need to go where attention is deeper, not just faster. The smartest brands don’t chase platforms. They chase attention. And the right kind of attention lives in the right kind of place.
