World’s Top Cleantech Site

CleanTechnica is the world’s #1 source for cleantech news and analysis. It entertains and informs approximately 6 million monthly global readers along with hundreds of thousands of social media followers. It is followed by some of the biggest names in the cleantech world on Twitter, where it enjoys tens of millions of monthly impressions.

CleanTechnica’s work has been referenced by the New York Times, Washington PostSlate, CNN, CNBC, MSNBCThink ProgressReutersScientific American, and plenty of other media outlets. Some of the cleantech industry’s top CEOs, directors, founders, and board members read us regularly.

CleanTechnica has been covering the cleantech industry obsessively since 2008 — before it was popular for mainstream media to dedicate blogs or subdomains to the topic.

CleanTechnica Through The Years

The following are just some of the indications that we are a top site to follow or reference for cleantech news, facts, or commentary:

  • 2011: CleanTechnica was featured on CNBC for one of the videos in CNBC and Harvard Business Review’s “Energy Opportunities” series. Site director/editor Zachary Shahan was interviewed in CNBC’s London studios for this video.
  • 2011: CleanTechnica won TreeHugger‘s 2011 Best of Green Reader’s Choice Award for Best Sci-Tech blog (the last year such an award was up for grabs).
  • 2012: CleanTechnica was featured on Mashable for a series on “5 Startups Improving Society Through Technology” (CleanTechnica being one of the five, even though we are technically just one part of a broader startup).
  • 2013: Site director Zachary Shahan, due to his role at CleanTechnica, was named one of the top 20 fuel economy influencers in a Spring 2013 study, alongside President Obama, NYC Mayor Michael Bloomberg, Tesla Motors CEO Elon Musk, and several other car company executives and policy leaders.
  • 2014: CleanTechnica consistently ranked near or at the top of Technorati’s “Top Green Blogs” ranking.
  • 2015–2020: CleanTechnica has been closely read by titans of industry and science, such as Elon Musk (who has responded to or liked hundreds of CleanTechnica articles), Jeff Bezos, Mark Z. Jacobson, Michael Mann, and Frunkpuppy Earl.
  • 2015–2020: The site has covered key events in cleantech in front row seats, from the Tesla Cybertruck, Roadster, Solar Roof, Model Y, and Model 3 unveilings to Xpeng, NIO, BYD, and Lucid Motors product launches to the Volkswagen ID.3 reveal.

In the past few years, CleanTechnica has also launched a podcast, CleanTech Talk; a YouTube channel, CleanTechnica.TV; and a research arm, CleanTechnica Research.

But What is Our Focus?

Technology-wise, our focus is solar powerclean transportwind power, energy efficiency, and energy storage. However, we also get into many other topics — geothermal, hydropower, nuclear power, climate change, etc.

Overall, our top goals are to:

  1. Inspire people and help them to take cleantech action in their lives.
  2. Share correct information on cleantech, including debunking widespread myths and horrible cleantech coverage in the mass media.

We want to be a useful site for the world and want to develop a strong, useful community of world citizens in order to help move humanity forward in a positive direction! Contact us here with questions or comments.

  • i am inspired to see some innovation.

    it was a nice feelings..

  • I don’t know how I found CleanTechnica or how it found me, but I liked it from the first. I almost dropped it in the interests of getting less email, however, since it seemed to come almost every day.

    But I kept reading it. Now I wish it came every hour.

    Not really!!!! But thanks for being there and doing such a great job.in all respects:content, scope, concision, humor. Thanks!

    • Thanks a lot! 😀

      Believe it or not, would love to cover about twice as many stories every day than we do. But it seems to be against the interest of our readers, and most certainly is against the interest of our writers (their pay would drop), so we don’t. 😀

  • Hi, I want some information about solar powered lamp post suppliers in India. Can you give me the website and contact information please.

    • I doubt anyone here has that sort of information. I’d suggest you spend some time Googling to see who makes a quality product and then contact them to see if they have a distributor in India or if they ship.

      Here’s a company that turned up with a quick search for “solar powered street lamps”. http://www.solarstreetlightsusa.com/

      I know nothing about them but I’d put them on your list and look for other companies. Then do your due diligence by checking quality and reputation.
      CalTrans – the California State highway department uses solar lighting at some more remote sites. You might contact them and see if they have any recommendations.

      Also, this could be a great industry for India. This is not a product that would take a lot of engineering.

  • I am about to come into a clear title for about 80 acres of flat Florida farmland from my grandmother’s estate. I want to take all 80 acres and develop a solar and wind farm. I could pay for the up-front costs with a loan against the equity in the property, then sell the energy wholesale to Florida Power and Light. Whom would I contact first because FPL are incompetent.

    • LOL!!! FPL is the largest renewables developer in the nation (NextEra) and even their alleged incompetence won’t allow them to install wind in Florida because the wind resource is too feeble. If you are comfortable, Mike, receiving other people’s money at the point of a gun, then go for it. But other people’s tax dollars are required for wind and solar to be built, and failure to pay our taxes results in incarceration (at the point of a gun if necessary.) Your call, dude. But I would NEVER get into a business that can’t make it on its own in the free market. I would find it to be severely anti-American.

      • Perhaps you should look at some wind maps for onshore and offshore wind resources in Florida.

        BTW, you must really be against nuclear which can only be built with taxpayer assistance and against coal which is supported by taxpayers to the tune of $140 billion to $242 billion a year.

  • POWER GENERATION – NEW ERA
    In Hydro Electric Power Generation Projects, we are
    generating Power with the help of accumulated water in Reservoirs at height. We utilize the down flow water Pressure to
    rotate Turbines.
    In this Project, we use people weight coming down
    from height, to rotate Turbines.
    For example,
    a) On Tirumala Hills, there will be 50,000 people at all times for generations together and daily. 1, 00,000 people are coming down and going up Hills for Lord Balaji Darshan. We can use their movement in Power Generation using Roller Coaster Technology.
    Power Generation calculations on Tirumala Hills.

    From SRIVARI METTU to Tirumala Hills the Slant Distance (say) 2 K.M. =
    2,000 meters.
    Approximately, how much Power Can be generated when 10 Tons Load
    (8 Tons Bus + 2 Tons for 50 Passengers in the Bus) slides down on trolley.

    As per notes from attachment, (Work & Energy Chapter – PAGE 6) the following is the ‘Power Generation Calculation’.
    Please follow Link:- http://www.onlineconversion.com/energy.htm
    One trip – 10 Tons Load (20 – Passenger filled car weight 2 Tons + 8 Tons Bus weight) generates 278 watt per hour as per enclosed attachments. –
    formula:- (load in kgs x gravity x ½ distance)
    10000 x 10 x 1000 = 10,00,00,000 Joules = 27777.8W
    27,778 Watts per hour
    To transport up & down Hills, Pilgrims –
    1,00,000 per day @ 50 persons in Bus per trip, the RTC will ply down 20,000 trips 20,000 trips per day
    For every Trip load the Power generated will be 28 K W

    These images are showing Public coming down on Roller Coaster in open cars, whereas, in our Project, we can arrange cars enter in closed Chambers, which roll down. These cars filled with Pilgrims who are chanting ‘Govinda nama sankeerthan’ during journey. In other words, we are providing ‘Garuda Seva’ to Pilgrims by transporting them up & down.
    b) At Chennai Central Railway Station, passengers getting down will move to Park
    Station to reach various parts of City through sub-urban Railway. A very
    little per cent age of Public depend on their own vehicles, 3- wheelers or
    Public Transport.We can shift the people from Chennai Railway Station to Park Station using Roller coaster Technology and also we can generate Power using their weight. We can arrange 20-seater Passenger trolleys in racks readily available on the platform. When Passengers getting down, they will be collected in trolleys and lifted to a height, say 30ft in the Chennai Central Railway Station Building and then Rolled down to Park Station.
    With this Project, Power Can be generated and along with shifting of men / material between Stations.

    BENAGALURU RAIL & ROAD PATH WAY PROJECT
    _______________________________________________________________________________
    In the 24 hours of the day there may be 50 to 60 trains are ‘coming in’ and ‘going out’ of Benagaluru Railway Station. With every train bringing in 1000 passengers
    each, the number of passengers it is handling (1000 * 50) 50,000 people. And out of them (say) 5% will ‘go out / coming in’ in their own Vehicles, another 10% use Autos, the remaining passengers will come to Kempa Gowda Bus Station to go to their destinations through Buses.
    Can we provide them easiest way to reach the Bus Station?
    Project Name: – BENAGALURU RAIL & ROAD PATH WAY PROJECT.
    ————————————————————————————————————————————-
    People cross the Railway Platforms through “Foot Over Bridge”. The Foot over Bridge height say 30 ft height. If we use a Lift for another 30 ft height, totaling the height is 60 ft height. From that height at the Centre of the Railway Platforms to Bus station we provide, a Path Way. It is just like a RAMP. People come down easily to Bus Station without any hurdles, like crossing Platforms, parking area, subway, steps, etc.
    We can provide trolleys with 20 passengers (2 Tons weight approximately) each which can slide easily to the distance and save the time & energy of the Passengers.
    Advantages in this Project:-
    (1) There is no Private Property in between these two points – Rly Stn & Bus Stn.
    (2) The height of the Foot Over Bridge at Railway Station and the Ground Level at Bus Station may be more than 60 ft
    (3) In addition movement of men / material, there will be scope of Power Generation – By sliding the 2 Tons Load Trolleys on the Rails on RAMP along with Pathway.

    ———————————————————————–
    These calculations I made for Benagaluru Path Way Project.
    2Tons Load (20 – Passenger filled car) generates 278 watt per hour as per enclosed attachments. 2000 x 10 x 50 = 10,00,000 Joules = 278W
    When train arrives into Railway Station, let us say, 1000 Passengers reach, get down and use the Transport will be 800 nos. 800 Passengers will be transferred in 40 Loads (800/20 = 40).Loads
    For every ‘four’ loads the Power generated will be more than 1 Kilo Watt
    (4*278 = 1,112). 1 K W
    With the Passengers in one train (40 Loads) we can generate 10 Kilo Watt Power per hour. 10 KW
    With the Passengers from 50 trains per day, we can generate 50*10 = 500 (.5 MW) Power. 500 KW =.5 MW

    How much Power required to lift 2 tons Load to 30ft height”
    “2000x10x9 ”
    2000 x 10 x 9 = 1, 80,000 Joules
    Hence, Power requirement to lift 2 Tons Load (20-Passenger trolley) to a
    height of 30 ft is: – 50 watt per hour as per following conversion link:

  • Giving US manufacturers an incentive to produce less or to shift times of production to times less convenient/efficient to their bottom lines and workforce demands careful consideration. Perhaps an analogy is that we pay (using our tax dollars) farmland owners not to grow crops on some land some years/seasons while allowing grain, dairy and meat prices to escalate and while also mandating some cropland is diverted from food production to energy production and while subsidizing farm equipment which does not require a financial payback justification for the full cost of the machinery upgrades. History shows that the more governments intervene in markets, the less efficient they become. This is especially true in complex markets such as energy.

    In addition, governments are mandating the consumption of wind electricity which produces counter to the cycles of electricity demand. The combined effect,then, is to have society bend to the whim of the weather.

    But specific to energy efficiency aside from wind energy, the basic question is: What are the net, long-term costs and benefits of forcing society to bend to the will of the electricity system vs. continuing the paradigm that the electricity system is required to bend to the will of society? The answer is foundational to all other considerations.

    • We already pay some industry to shut down when supply is significantly stressed. And some industry runs their most energy demanding processes late at night when electricity costs are lower.

      We’ve also seen some studies that find that some commercial uses can be cut without causing even noticeable changes to workers or process. For example one building’s air circulation system was adjusted up and down to match solar input. Over time the same number of air exchanges were made but the flow varied with passing clouds.

      It’s less likely to be government regulated but a financial arrangement with the power provider. EV charging, for example, will likely be commonly used as dispatchable load. The average EV will need about three hours of charging. Utilities could control the actual time of charging and offer low rates in exchange.

      Utilities are going to be willing to sell power at a better rate when they have plenty in order to lower demand when supply is low. That will allow them to avoid bringing expensive peaking power on line.

  • I just discovered CleanTechnica and so glad I found ya. Great work! I look forward to contributing to the conversation you’re having with the world. EV+PV makes undeniable ecologic and economic sense.

    • Welcome. The more good input we get the more we all know.

  • I did a search on the web site for Alabama Solar Power Assoc for STEEL MILL and there was ZERO data available on the subject. So, can you tell me the name of the steel plant in Alabama with a large solar presence?

  • So how did you manage to build the nr 1 portal for renewables and how do you keep nr.1 ? It’s like a wiki where people can help building / referencing clean techs and help organising, help adding tags?
    Thy

  • Dear Sirs,
    Thanks for an instructive and inspiring site.
    However, after seeing article after article praising Tesla, I get an uneasy feeling. Tesla certainly deserves praise, but is it healthy with this unidimensional bias? Development is multidimensional, and requires a comprehensive approach, i.e. “all things considered”.
    Is the site, or are major participants in it, payed by Tesla?

    Sorry for coming with such suspicions,
    Jonas Blomberg

    • The editor and one of the main contributors has an admitted favortism towards Tesla and great admiration for its CEO Elon Musk. Disclosure of this along with the fact that he is long on Tesla investments is usually included in these pieces and known to regular readers.
      At the same time there are a wide variety of other subjects covered here by him and the other authors on a daily basis.
      Yes Tesla shows up frequently because they are making such a difference in the adoption of EV’s in the US and foreign markets along with upgrades to their current product.
      But if you will stop back by you should find something of interest to read in addition to that topic.

    • Jonas – Tesla is shaking up the world and showing how to get off petroleum. And do it quickly.

      Do you suggest people not be enthusiastic?

      • No, enthusiasm is important.
        But impartiality and factuality is also. Otherwise you will quickly lose impact.

        • What EV stories do you think should be covered more?

          Who’s not getting their day in the Sun?

          I looked through the last 100 articles on the site. Seven (if I counted correctly) were about Tesla or Tesla-related activities. Tesla not only builds cars like GM, Ford and Nissan. Tesla also is building a huge battery plant, getting into the energy storage business, and building a global network of rapid chargers. One might expect Tesla to get a bit more attention than the companies that are doing little.

          What factual errors do you think have been made?

          • Bob,
            My impression was much more Tesla-dense. I frequently read about EVs and FCEVs. Without exact statistics, the bias that I talk about is mostly omissions:
            Metal-air and flow batteries, what is hype what is realism?
            Economy of electrolytic production of hydrogen on site. With a global perspective. The US situation is of interest, but gas price is especially low there.
            In which situations are fuel cells clearly superior to batteries? The situation for long distance buses and trucks should be highlighted.
            FCEVs have a range advantage.That argument will be shattered if battery energy density doubles. How much hydrogen can a four-seated FCEV have on board? They seem to be close to a maximum already.
            The price of fuel cells has come down considerably. So has the amount of platinum in them. According to NREL their price is similar to a diesel engine. Yet there is much talk about fuel cells being extremely expensive and their inordinate usage of rare metals. Time for a moment of truth.

            Hydrail is an interesting and economic alternative.
            These are a few subjects which deserve more extensive coverage at Cleantechnica.
            Yours,
            Jonas Blomberg

          • Metal air – you mean aluminum batteries? They have been covered and at this time they are more of an idea than a product in use. Flow batteries have been covered in multiple articles but AFAIK there is no new news to be reported. (I have a Google Alert set for flow batteries and it’s found nothing.)

            Fuel cells. I know of no where in the transportation world where fuel cells make sense.

            The range difference between the Toyota Mirai and Tesla ModS with their new battery pack is about 12 miles.

            Fuel cell buses were tried in Canada and ended up being scrapped. Battery powered buses are being sold in the hundreds.

            Toyota set up an “onsite” hydrogen fueling station. The price was $2 to $3 million and could fuel only 20(?) cars a day due to the time needed to produce the H2. (I’m fuzzy on the details.)

            Seems to me that CT has covered and covered FCEVs.

            I don’t think hydrail has been covered. I’ll pass that on to Zach.

            If you have specific topic requests or ideas send them in. The intention is to cover all potentially useful technologies.

          • Bob,

            I can easily step out in loose sand, but here are some comments to your comments:

            1. Alternative battery technologies to be covered are:

            Gildemeister’s vanadium redox flow batteries. UET has doubled their energy density. Imergy say that they can produce a flow battery at 220$/kWh by 2017.

            ViZn (zinc-iron electrolyte, cheaper than vanadate), Austin,Texas, produce Z20 grid storage units, targeting $200 per kilowatt-hour in the next two to three years.
            2. Fuel cell buses.
            The Whistler buses were scrapped because of clumsy hydrogen distribution, not malfunction. They were more expensive than diesel buses, which replaced them. A step back.
            You fail to mention the many fuel cell buses which operate in the world today. Ignorance?
            3. You fail to mention the stations which produce hydrogen on site today (like those from H2Logic) in Denmark, Norway, Germany, UK and Japan. Ignorance?
            Jonas

          • Vanadium flow batteries. About 15 articles, Five on Imergy. At least one on Gildemeister.

            http://cleantechnica.com/?s=vanadium+flow

            Two on ViZn plus several in which ViZn is covered.

            http://cleantechnica.com/?s=vizn

            A few on fuel cell buses and several in which FC buses were part of the story.

            http://cleantechnica.com/?s=fuel+cell+buses

            There have been articles about on site H2 generation but I don’t think there’s been an article that inventoried the various stations that are running.

            http://cleantechnica.com/?s=hydrogen+on+site+generation

            I don’t think CT has done anything on H2 Logic. Looks like their H2 stations are about like the Japanese H2 station we covered. Capable of fueling about 20 cars per day. Or is there something ‘more special’ about them?

          • Bob,
            Thank, I enjoyed some articles that I did not see before.
            1. A lot of news on flow batteries. Embarrasing for the Gigafactory?
            2. There is more to Fuel Cell buses than you state.

            3. It would be interesting to see a comparison of on site with transported hydrogen.
            H2Logic came out early, deserve a look. I think you are right, their stations were intended for starting up hydrogen distribution. I think their initial models had a limited capacity.
            4. I also miss a broad comparison of biogas, biodiesel, bioethanol, hydrogen and electricity for transportation. Did CleanTechnica cover that?
            Jonas

          • ​I don’t know what is going to happen with flow batteries. At this point they are talking about trying to get down to $200/kWh while we have other battery systems (zinc, liquid metal, lithium-ion) aiming at $100/kWh.

            And some of the battery systems project a very long cycle life (~30 years of daily cycling).​ The flow battery advantage is that by adding more tankage we can store a lot more energy for less money that with battery storage. (Pump-up hydro has the same advantage. Reservoirs can be sized to hold a lot of storage.)

            I don’t see Panasonic/Tesla’s lithium-ion batteries becoming a major grid storage technology. They are focused on packing power in smaller space for EV use.

            As far as “embarrassing” for the Gigafactory, don’t see that. Aiming at different market. P/T may sell some storage to end-users so they can optimize their solar or cut their peak use. I don’t see much use a the utility side of the meter.

            If you know of any fuel cell buses that are superior to the ones covered give us a list and they’ll get worked into the ‘to do’ list. What I’ve run across, that we haven’t covered, wasn’t impressive. One (school bus?) company reported needing to purchase a spare stack because after six months use the stack had to be removed and sent back to the factory to be “dried out”. That was technology not promising.

            A comparison of on site and transported hydrogen? Do you know of any ‘factory’ that is making green hydrogen and distributing it to FCEV fueling stations? (I’m seeing no need to cover the distribution of H2 from reformed methane. That’s no solution.)

            “(A) biogas, biodiesel, bioethanol, hydrogen and electricity (for) transportation”

            Certainly a lot of attention has been given to H2 vs electricity. Biofuels are individually covered. I’m not sure what comparison could be made since they aren’t in commercial use enough (or at all) to say much about them.

          • Bob,

            1. Flow batteries. More than grid storage? What about the hyped Quant F car?

            2. FCEV buses: The ones used in Europe are mostly Van Hool buses with Ballard fuel cells. The Oslo buses have a long record, I heard that they work OK. Why negative about FC buses?

            3. “Do you know of any ‘factory’ that is making green hydrogen and distributing it
            to FCEV fueling stations?


            Yes. Linde, Air products have such. Hydrogenics, H2Logic, Proton OnSite are a few on site H2 producers.
            4. An unbiased comparison of fossil-free or fossil reduced energy sources is important, especially as a basis for green politics.
            5. By the way, your sweeping statements regarding FCEVs did not include forklifts. There are thousands of fuel cell forklifts around. Why?

          • Why H2 forklifts? I imagine a combination of reasons. Closed warehouses, especially cold/frozen storage is not the place for burning propane (carbon monoxide) and lead acid batteries don’t care much for the cold.

            Maybe they’ll stick with H2, but battery swapping with lithium-ion may be a less expensive route. Just design a battery pack that insulates the batteries. They’ll heat up as they are being charged and will give off heat while discharging.

            As I said, I haven’t seen any onsite H2 systems that are impressive, even marginally useful. A couple of million dollar for a fueling station that can fill only 20 cars a day? Electricity and water extra. That’s not a solution.

            Van Hool supplied 5 fuel cell buses to Oslo in 2012. It looks like they may have sold a couple of dozen elsewhere. Does this make them more than a demonstration? BYD is selling 4,000 electric buses per year in China and hundreds more around the world.

            Overall hydrogen is just not a good idea. The main source is methane and it will continue to be as long as people attend to cost. Cheap H2 from water and electricity is only a dream. It’s very inefficient to go from electricity to H2 and back to electricity.

            The Quant F hasn’t yet appeared, has it? And isn’t it some sort of exotic not intended to be a transportation solution?
