Top hashtags for energy startups

Posted by Sara Hawthorn

Social media is a great tool for energy startup businesses to engage with potential customers, the media, investors and build an online presence. Using hashtags is standard practice in posts but what are the top energy sector hashtags to use on different social channels? We’ve compiled our top 5 hashtags, broken down where they’re used, who by and whether you should have them in your hashtag list.  


1. #RenewableEnergy

Might seem like the obvious choice, but is it worthwhile? Each hour 26.2k

Who’s using it?

It’s primarily used by an American audience, followed by Australia, India and then the UK comes in at fourth with 10% of the usage.

Spelling matters

According to hashtagify 51% of the time, #renewableenergy is used, whilst 46% of of the time it’s #RenewableEnergy. From an accessibility perspective, using leading capitals is better for screenreaders and we always recommend this approach when using hashtags.

Where is it used?

Twitter usage is relatively low, but the #renewableenergy hashtag on LinkedIn has 806,768 followers. If this one is relevant to your product and/or services then LinkedIn is the place to use it.

Other hashtags which are used in relation to #RenewableEnergy include #solar #climatechange and #renewables


2. #EnergyTransition

A general energy hashtag is #EnergyTransition used for all-encompassing topics and areas related to the, you guessed it, energy transition. 

How often is it used?

On Twitter it has a surprisingly low usage – averaging 8 tweets per hour with 9 retweets per hour. However, the same hashtag in German – #energiewende – has far higher visibility. On LinkedIN the hashtag has 29,416 followers, much lower than #RenewableEnergy, but considerably more traction than on Twitter.

Should you use it?

As a general catch all term it’s a good one to include in your hashtag list for Twitter and definitely one to use on LinkedIN posts. However, consider using #energiewende on Twitter if you have a European market. 


3# CleanEnergy

This is a term we’ve seen increase in popularity in recent months. The word ‘clean’ has been placed in front of many words in recent years – ‘clean eating’ being perhaps the most well-known. The hashtag averages 35 unique tweets an hour with a high visibility rate of 138.7k. 

Should you use it?

It’s definitely on the up in terms of usage, but use with caution. There are issues with ‘clean’ and potential greenwashing. Only use it if pointing people to an article or resource on clean energy, or if your product or service is actually either using green energy or 

What platform should you use it on?

As this one is on the rise use it on Twitter, LinkedIN and Instagram. There are around 638k post tagged with #CleanEnergy on Instagram. 

Related words to consider

In specialist fields like energy, niche can be a good thing – using popular hashtags can improve visibility, but specific hashtags are often used and followed by people with an interest in that area. Consider adding terms like #CleanEnergyFuture #CleanEnergyNow and #CarbonFree to your hashtag list.


4. #ClimateChange

This one covers a big range of topics including sustainability, environmental stories, circular economy and energy. Because of that it’s strong on visibility averaging 167 tweets an hour, 95% of which are in English. Leading capitals (ClimateChange) are used 40% of the time.

Where is it used geographically?

The USA tops usage, with 44.85% of usage, followed by Australia, Canada, the UK, Pakistan and India, with other European countries like France, Italy and Germany all coming in around the 2% mark. 

How does it perform on different platforms?

On Instagram there are 4.9m posts tagged with #climatechange, on LinkedIn it has 131,549 followers, and on Twitter it has an hourly visibility of 728,950. 

What other hashtags are used with it?

Unsurprisingly, it’s phrases like #GlobalWarming #environment and #ClimateAction that are often used in conjunction with the #ClimateChange hashtag. 

When should you use it?

The key here is relevancy – if your link to climate change is tenuous don’t use it – opt for something more focused or industry specific. If you’re sharing content from another source, or commenting on a wider issue that directly links to climate change issues, for example collating crowd sourced content on the top three climate change problems then make it your primary hashtag. 


5 #Energy

Seems so obvious, we should have started with this one, right? But it’s not as clear cut a hashtag as you may think. For example on Instagram, #energy has 30.7million posts, huge numbers of them are focused on health and wellbeing covering  spiritual energy, energy healing, energy drinks and energy work. Not the energy that powers your kettle 10 times a day.

Who uses it?

It’s used by oil and gas, renewables, sustainability businesses in addition to the health and wellbeing sector. It’s probably the most overused and cross-purpose hashtags to use. The UK is has the second highest usage of the hashtag behind America.

Is it worth using?

Yes, but not in isolation. The most common words used alongside it are #news #job #solar and #green. If you want to use it, make sure you add more specific hashtags to your posts – for example #offshorewind #energy. 

Hashtag research can take time, but it’s worthwhile to build a bank of terms that work for you, there are whole specialist subjects that branch off from the terms above so whether you’re in battery storage, energy storage, wind, solar or hydrogen there are terms to use to bring your better visibility and engagement with your target audience.
