For cleantech companies, social media is more than just a place to share updates—it’s a critical tool for connecting with investors, customers, and industry leaders. But with so many platforms available, where should you focus your efforts?
Not all cleantech startups have the sexy quotient or broad appeal of sectors like solar, AI, robotics, and fusion energy, which currently attract significant attention and investment. If your company doesn’t fall into one of these high-profile categories, the solution isn’t to cast a wider net but to niche down. The more specific and targeted your message, the more likely you are to attract the right investors, partners, and customers.
In addition to niching down your message, you need to pick your social media platforms based on your particular objective, whether that’s building a higher profile for your brand, targeting potential investors, creating a top of a sales funnel, or building your email list.
1. LinkedIn: The B2B Powerhouse
If you’re in cleantech and you’re not leveraging LinkedIn, you’re leaving money on the table. With over 310 million active monthly users, LinkedIn is the top platform for industry professionals, investors, and decision-makers. According to
DG+ Design, LinkedIn drives more than 50% of all social traffic to B2B websites and blogs—making it the most powerful tool for business-driven cleantech companies.
Why It Works for Cleantech:
• Investor Outreach:
VC firms and angel investors regularly browse LinkedIn for emerging trends and technologies.
• Thought Leadership:
LinkedIn has targeted sectors like “Cleantech,” “Sustainability Professionals,”, “Sustainable Energy Development,” and so on where you can find other individuals who share your passions and pursuits.
• High-Value Networking:
Unlike other platforms, LinkedIn fosters professional connections that lead to real-world partnerships and funding opportunities. While LinkedIn is free, I highly recommend a paid subscription to their Sales Navigator platform. While not a robust CRM for companies that need to manage thousands of contacts, it’s an excellent place to scout for talent and send private messages that are warmer than a typical cold email.
How to Use It Effectively:
• Send personalized connection requests letting the recipient know (in just a few characters) why they should want you in their circle.
• Engage with investor and industry discussions in LinkedIn groups.
• Use Sales Navigator to build relationships with investors, talent, and potential customers.
2. Twitter (Now X): Fast-Paced Thought Leadership
Twitter is an ideal platform for real-time updates, industry news, and engaging with policymakers and media. The transformation of the platform under the ownership of Elon Musk has driven away a segment of subscribers who amplified the reach of cleantech companies, but journalists and high profile investors still post regularly.
Why It Works for Cleantech:
• Direct Engagement:
Connect with policymakers, journalists, and industry influencers in real-time.
• Breaking News & Trends:
Stay ahead of the latest developments in the cleantech sector.
• Visibility for Advocacy:
Organizations pushing for sustainability regulations use Twitter as a megaphone for policy influence.
How to Use It Effectively:
• Post short, data-backed insights that provide value to your industry.
• Engage, engage, engage. The “social” in social media implies that it is to be used as more than a one-way megaphone. Your inside marketing team or marketing agency should be responding to other content as well as creating your own.
• Use #hashtags strategically, such as #Cleantech #Sustainability #GreenEnergy to boost discoverability.
3. Instagram & YouTube: Visual Storytelling for Broad Engagement
If your cleantech innovation is highly visual—think robotics, sustainable consumer products, or ocean cleanup projects—Instagram and YouTube can be powerful platforms. According to
DG+ Design, Instagram is a go-to for product discovery, with 81% of users using the platform to research brands. The nice thing about the platform is it doesn’t require the level of production that takes time and drives up costs. While Instagram is famous for its filters, in many ways the platform is less filtered with high production values. Its users like the more impromptu and intimate feel they get from the platform.
Meanwhile, YouTube’s massive audience (over 2 billion monthly users) makes it an essential platform for educational content, deep dives into your technology, and storytelling. Because YouTube is owned by Google, posting content on their video platform has the added benefit of improving your search engine rankings.
Why They Work for Cleantech:
• Instagram is ideal for B2C brands selling green products, sharing eye-catching photos, short videos, and behind-the-scenes looks. It’s far less impactful for B2B or B2G brands. Sprout Social’s 2024 Media Content Strategy Report revealed that Instagram is the top social media platform for discovering new products. Accordingly, Instagram’s users skew heavily towards advertisers desired 18-49 consumer demographic. https://sproutsocial.com/insights/instagram-stats/
• YouTube is a much better fit for hardtech companies that have lengthy sales funnels. excels in long-form storytelling, explainer videos, and case studies.
How to Use Them Effectively:
• On Instagram:
The watchword is “entertainment.” Instagram users scroll their feeds to be entertained. According to Sprout Social’s 2024 Media Content Strategy Report, videos less than 15-seconds are more effective.
• On YouTube:
Two-thirds of a B2B sales cycle happens online before a person in your company is contacted. Your ability to create educational and impactful video content that targets a specific customer’s problem will go a long way to determining whether they will ever reach out or share their email. While video length on YouTube can and should be longer than on Instagram, any video longer than two minutes will test your viewer’s patience in an ephemeral world of endless content.
• Post video testimonials from customers and investors to build credibility.
4. Facebook: The Community Builder
Despite perceptions that Facebook is fading, it remains a key platform for community-driven cleantech brands. Jokes aside about Facebook being the preferred social media platform for grandparents, with over 3 billion users, it’s especially effective for advocacy campaigns to share information with like-minded followers who can amplify your message. Facebook’s private groups are also an excellent way to build community. It’s far less effective as a sales funnel for B2C or B2B companies.
Why It Works for Cleantech:
• Engages Local and Niche Communities: Good for municipal sustainability projects and advocacy campaigns.
• Supports Long-Form Content: Unlike Instagram or Twitter, Facebook allows for more detailed storytelling.
• Great for Paid Ads: If you’ve ever been creeped-out by how much Facebook’s algorithms seem to know about you, it’s because Facebook’s advanced targeting lets you pinpoint specific demographics with uncanny accuracy.
How to Use It Effectively:
• Create a Facebook Group around a specific niche, such as “Future of Carbon Capture” or “Green Building Solutions.”
• Run targeted Facebook Ads to reach angel investors on Sand Hill Road or frame your message with early adopters in the environmental community who live in a specific zip code.
• Post a mix of video, text, and infographic content to engage your audience.
• Build relationships. Social media is a two-way street. Respond to inquires in a timely fashion.
5. Pinterest: The Unexpected Powerhouse for Green Living
While often overlooked, Pinterest is a valuable platform for cleantech brands focused on green consumer products and sustainable lifestyle content. According to
WebFX, Pinterest is especially effective for DIY sustainability projects and renewable energy tips.
Why It Works for Cleantech:
• Strong Search Intent:
Users actively seek eco-friendly solutions and sustainable living ideas.
• High Engagement for Green Brands: Cleantech companies selling consumer-facing products (e.g., solar panels, sustainable packaging) can leverage Pinterest’s visual format.
How to Use It Effectively:
• Create pinnable infographics about sustainability.
• Share educational guides on topics like “How to Reduce Your Carbon Footprint.”
• Link posts directly to landing pages that drive conversions.
Niche Down to Stand Out
Instead of trying to appeal to everyone, find your tribe—investors, customers, and policymakers who care about your specific problem and solution. A more targeted approach will attract the right engagement and increase your chances of getting noticed.
