Dan Appel Damn Zach, I am impressed! You are quite the busy activist. Keep it up! http://lightngreen.wordpress.com Zachary Shahan haha! thanks a lot, Dan! 😀 doing it as a job these days, but comes from that activist spirit — definitely have that in my blood 😀 share any stories you like! can help a ton 😀 http://far-from-equilibrium.blogspot.com/ Ruth Anthony-Gardner Your Jan 14th post “CO2 May Actually Have Twice the Effect on Temperature climate Models Predict! (NOT GOOD)” caught my attention, as you summarized the new information and integrated it with related findings so well. This is such a horrific revelation, I need to talk about it with others who are concerned. But I haven’t found any social network site that supports such discussion. MySpace used to have ecology groups, but now it’s focused entirely on entertainment and celebrity non-news. Any suggestions? http://lightngreen.wordpress.com Zachary Shahan hey, Ruth. thanks for the comment! really appreciate it and happy you are interested in these matters. there are a number of green groups on Facebook and Twitter. Of course, I would be happy if you joined Planetsave’s Facebook group (http://www.facebook.com/psave) and also friended me personally on Facebook (http://www.facebook.com/profile.php?id=629025579) — get into little discussions on these matters there. also, always welcome to comment on posts on http://www.Planetsave.com — a lot of discussions happen on blogs like ours — hoping to build up a bigger and bigger community on our blogs in 2011. http://www.facebook.com/lyfsfun Kevin Foster Hello Zachary I am looking for advice and information on solar farms.Today I was asked if I would work up plans on a 165 acre solar farm. First I want to talk with people that have built farms. I need to find out what are the three best companies to look into for the panels. It seems that a top line company would have staff to help me through the process.The site is open land south of I-10, north of highway 90 and is bordered by pastures on 3 sides and the highway on 1 side. It is close to the Gulf and the wind does blow alot. That makes me wonder if we should look into windmills also. A very large power plant is about 4 miles away. If you can help or get me in touch with the right people that would be nice. Thanks for your time and nice to meet you. On a side note I am writing a reasearch paper on humanitarian logistics and would like to add a few interviews to it. Just in case you have been involved in that or know people that have. http://zacharyshahan.com Zachary Shahan Hello Kevin, We’ve been in touch, right? I’ve got this comment pending, but think I’ve already replied by email, right? http://twitter.com/carbonmind carbonmind (@carbonmind) Zachary: did you shoot the video fo Chu and Gates at Arpa-E? Could we please publish a still from it on MIT’s TechnologyReview.com? thanks: Conrad http://zacharyshahan.com Zachary Shahan hey, i didn’t film it. dept. of energy did. free to repost, just use the YouTube embed link or whatever you typically use for YouTube videos. 😀 Muhammed Bagwan You speak of Al Gore as focussed against big money in politics — didn’t his family make millions off of tobacco (a pollutant of the earth?) All politicians are the devil in disguise — best summarized in the old joke: “What did the devil say when man invented religion? Here, let me organize it for you. Also, not impressed by Solyndra or any of the other democrat/republican energy policies — we’re doomed anyways in the next 100 years with the proliferation of nuclear devices by rogue states. “I am become death the destroyer of worlds.” http://zacharyshahan.com Zachary Shahan From what I’ve gathered, he is less than proud of his family’s role in tobacco… and that is one big thing that drove him to work so hard to educate people about global warming. Anthony Todd Zach, Found your article about solar wind crowdfunding elsewhere. Want to get all these types of CF projects on my LinkedIn group Crowdfunding Projects. It’s free exposure to a group that digs crowdfunding. Please pass the info on, use it yourself or send useful links for me to reach.

Thanks. 😀 Jake Hey, could you help me out? I am researching the growing link between crowdfunding and renewable energy. For entrepreneurs in the US that would be looking to start a renewable energy project, where can I find more about the legal regulations/hurdles that entrepreneurs would need to overcome? Could you point me in the right direction? http://zacharyshahan.com/ Zachary Shahan Hmm, not sure exactly. But possible folks you could ask are Solar Mosaic and RE-volv. Or others we’ve covered: http://cleantechnica.com/tag/crowdfunding Charlotte Zang Momentum Dynamics has successfully charged the Chevy Volt with its innovative wireless technology at the full power capacity of the vehicle. This is a significant technical accomplishment due to the complexity of the Volt, and a major milestone in the development of wireless charging as a crucial enabler for the widespread acceptance of electric vehicles. I have a complete press release which I would love to send to you. What’s the best way to get it to you? http://zacharyshahan.com/ Zachary Shahan Hey, thnx, think I got it, have passed it on to writers. Avid Solar Fan Hi Zach, I like your articles on Clean Technica. Happy Holidays and A Happy New Year! Also, I found an inaccuracy in the article “Permitting – A Nightmare for the US Solar Industry” you published today (12.23.12). On the graph titled “Breakdown of cost differential between German and US residential PV” (second from top) on the left side it says “$2011/W”. An innocent typo. However, it confuses the reader by implying the COST of one watt is 2011 dollars!! (when you obviously meant “cost per watt in 2011 dollars”). Here are a few options: 2011 $/W or (2011) $/W or $/W (2011 dollars). Happy writing! Avid Solar Fan http://zacharyshahan.com/ Zachary Shahan Thanks. Happy Holidays & Happy New Year! 😀 Unfortunately I didn’t create the graph, it’s from NREL. Didn’t cross my mind that would be confusing, but probably smth worth passing along to NREL. http://MrEnergyCzar.com/ MrEnergyCzar Hi Zach, thanks for posting my Chevy Volt Q&A in one of your articles. I’ll be doing those Q&A vids every other Tuesday. Here’s the latest Peak Oil News which just came out. Feel free to post. Happy Holidays. MrEnergyCzar http://zacharyshahan.com/ Zachary Shahan Thanks. Happy Holidays! 😀 kirv Zach – Could you find out and write up how Germany gets its homeowners to install solar panels on their roofs? There is a barrier in the U.S. that is the learning curve for U.S. homeowners on what to buy, whom to hire, how much it costs, and psychological prejudices over aesthetics and belief that renewables aren’t competitive still. Why are German homeowners not resistant the way American homeowners are? And what about rental residential buildings? Do Germans get apartment building owners to install solar, too? http://zacharyshahan.com/ Zachary Shahan this site is definitely one to check out (and think they can answer your questions better than i can): http://energytransition.de/ but, basically, Germany has stimulated massive solar growth via a simple but attractive policy: a solar feed-in tariff. as this stimulated installations, the market matured, bringing down various “soft costs” (which is basically where US & German solar costs diverge). Furthermore, Germany has much simpler and cheaper permitting procedures than US locales. Much more info here: http://cleantechnica.com/2012/12/12/renewable-energy-big-pic-part-2-19-charts-graphs/ Molly I am wondering if you have a quick answer as to what legal restrictions determine whether a third-party solar company such as SunRun offers a PPA versus a lease in different areas? http://zacharyshahan.com/ Zachary Shahan I don’t, sorry.

MrEnergyCzar http://www.facebook.com/pieter.meyer.330 Pieter Meyer Hi Zach I am in the market for a wind turbine (only one) though it seems as if the available information currently is slanted towards big deals, i..e like governments installing hundreds at a time. How about an article on the retail side of wind turbines, to make it easier for an individual to know what the options are? http://zacharyshahan.com/ Zachary Shahan Hmm, that’s certainly a topic I don’t know a ton about… will try to dig in there… http://MrEnergyCzar.com/ MrEnergyCzar Hi Zach, here’s my latest EV related video… Thanks, MrEnergyCzar http://MrEnergyCzar.com/ MrEnergyCzar Hi Zach, Here’s my latest Peak Oil related news video for one of your articles.. I appreciate your support. Of course one of your articles is in the video… MrEnergyCzar Bill Dear Zach, I would like to know your views on the issue relating to the difference in solar output in summer and winter. This seems to me a much bigger problem than intermittency during the day. For example, while Germany had a massive 20+ GW solar peak in August 2012, in January it frequently only produces 2 GW peak (at noon). http://www.sma.de/en/company/pv-electricity-produced-in-germany.html Without storage, how would we deal with this huge discrepancy? I.e. 100 GW installed in the summer would need 1000 GW installed in the winter for the same output. But 1000 GW installed in the summer (hypothetical) would produce way more electricity than needed. Interested in your thoughts! Thanks. Bill http://zacharyshahan.com/ Zachary Shahan Thanks. Good question/point. I think one of the main keys is a good energy mix — one option will never do the trick. Luckily, wind is more abundant when solar energy isn’t, so they make a very nice complement. Storage would help, but seasonal storage is a bigger issue than nightly storage. And a good, extensive grid is key, imho. At least in countries that don’t have good year-round renewable energy resources. http://www.facebook.com/lindsay.sturman Lindsay Sturman Dear Zach, How do we get the spinning solar for our homes? Thx! http://zacharyshahan.com/ Zachary Shahan Hey, A production prototype hasn’t even been developed yet. Have to wait to see if it turns out as planned or doesn’t make it through the challenging process needed to become commercially viable. We’ll see. For now, there’s a good chance normal solar power is a good investment for you. 😀 http://MrEnergyCzar.com/ MrEnergyCzar Hi Zach, Here’s my latest EV related video for you to use.

Thanks, MrEnergyCzar http://MrEnergyCzar.com/ MrEnergyCzar Hi Zach, Here’s my take on the Tesla vs. New York Times debacle. Hear Elon Musk’s actual response. MrEnergyCzar http://zacharyshahan.com/ Zachary Shahan Thanks. 😀 Brian Smith I’m about to buy a Nissan Leaf, and I’m very excited. I was a bit surprised to notice that the elimination of a few tons of CO2 emissions is valued at about $45-$60! The price of carbon emissions is so low, wouldn’t I have more impact by just buying emissions rights and retiring them?! That process is difficult, it seems, for an ordinary person such as myself, but I’d have more impact on CO2 emissions by throwing a few thousand dollars at it than putting solar panels on my house and buying an electric car, wouldn’t I? I’m still going to do both those things, starting with the LEAF, but I’m also looking for ways to have the biggest CO2 emission reduction impact PER DOLLAR SPENT that I can. What would that be? http://MrEnergyCzar.com/ MrEnergyCzar You’re referring to the carbon credits offsets which are a scam. The reason it’s a joke is that to offset, say a flight, it would only cost you $50 but in reality it should be $1,000. Your carbon use for one event isn’t being spread out over the year but more like 20 or 50 years on the promise of a tree being planted and never cut for 50 years etc… buying pure clean electricity is one very cheap easy way to do it however…opt in with your power company. http://zacharyshahan.com/ Zachary Shahan Thanks for the response! Better than I would have given. I haven’t researched it enough to know, but I have heard many say that the carbon credits are far too easily manipulated (those receiving the credits are not doing much or anything beyond what they say). But I really haven’t researched in enough to weigh in. http://MrEnergyCzar.com/ MrEnergyCzar My solar credits can be sold for about $50 per 1,000 KWH on the Chicago Climate Exchange which is dirt cheap. Since you’re a researcher, the big banks are behind the exchange and don’t be surprised if complex futures with the carbon credit market happens and ends bad. No one can buy or negate their carbon footprint with carbon credits because with one year to offset, you’d have to live 40 years for the purchased offset to be realized. They know no one would pay a grand to offset a flight. could be a future article. The Climate Exchange…. MrEnergyCzar http://zacharyshahan.com/ Zachary Shahan Thanks for the info. Yeah, this could be a post or 5! http://MrEnergyCzar.com/ MrEnergyCzar Looks like my green tags or REC’s are being sold somewhere else since it appears the chicago climate exchange is now closed… now i’m interested….I’m in CT but a company in Maine handles people in CT with solar credits and makes one sale per year on an exchange, will ask them where now.. http://MrEnergyCzar.com/ MrEnergyCzar Zach, here’s my review of Kunstler’s latest book, Too Much Magic, thanks MrEnergyCzar http://xeeme.com/MrEnergyCzar MrEnergyCzar Zach, Here’s my latest Energy News video.

Thanks, MrEnergyCzar jeffrey Your Masdar article failed to discuss the problems associated with mobility within the city. For now, walking and bikes are probably sufficient. However, as the city grows, the distances will get larger and an automated circulation system of some sort will be needed. The original plan, devised for Foster and Partners, provided for this need in an undercroft level that was to be below the pedestrian level, formed by a platform upon which buildings were to be built. The aurtomated vehicles operating now at Masdar were to eventually serve the entire city, providing a very safe and pleasant way to move about. However, the undercroft plan has been dropped and that circulation problem has is no longer feasible. The pedestrian level features streets that are not suitable for automated vehicles as they are too narrow and not well connected. And no provision for parking vehicles has been provided in the original plan, Electric vehicles need places to park and recharge their batteries from time to time. I’d like to see an article that includes a discussion of this unsolved problem – or if it has been solved, that describes the solution that has been found. A city of 40,000 does need an internal circulation system that goes beyond walking and riding a bicycle. Getting to and from Masdar to other locations in the country is quite another matter and can be solved by the central mass transit route that will pass through the city or by electric autos that have to be parked outside of the walls that the plan calls for to surround the entire city. http://zacharyshahan.com/ Zachary Shahan i’m not intimately aware of the plans, but am sure they will work out a plan for other modes of transport as the city develops. personally, i’ve live in a city of ~150,000 people in which 50-60% of commutes (not sure of the total trips split) were by bike. highest quality of life i’ve ever seen. don’t think limiting car use will be a downside. http://xeeme.com/MrEnergyCzar MrEnergyCzar Zach, Here’s my latest “Sugarcane Ethanol” video… Thanks, MrEnergyCzar http://xeeme.com/MrEnergyCzar MrEnergyCzar Zach, Here’s my “Why Are Gas Prices So High?” video.

MrEnergyCzar http://zacharyshahan.com/ Zachary Shahan Thanks, on my list. 😀 David Orndoff I read your blog on Pear Energy. It sounds like a scam to me. They have no resources other than a billing package. It appears to be a duplicate billing scheme where they are charging a premium for energy. I already enroll in a green energy program with my local energy company, Northwestern Energy, where i pay a premium for my green electricity. To me it appears they are wasting a lot of human hours creating and maintaining a billing scheme that has no merit. Would not my money be more wisely invested in an actual company that creates green energy resources? http://zacharyshahan.com/ Zachary Shahan Pear is doing what some utilities (like yours) and regions are doing. The option you have isn’t available everywhere — so this serves the option to more customers. Also, Pear is focused on acquiring this green energy from small-scale developers, supporting community solar projects and individual landowners more — a bit better than what most (or all) utilities offering such a program are doing. http://xeeme.com/MrEnergyCzar MrEnergyCzar Hi Zach, Here’s my latest EV & related news video… Thanks, MrEnergyCzar Bob Twain Hi Zach, The efficiency increase Sharp made to take back the record for multi-junction non-concentrator cell is 0.2%, not 0.02%.

The problem with numbers like that is they include a lot of very inefficient systems. Modern, efficient animal ag systems produce a lot less GHG per calorie of human food than that value indicates. I study efficiency in the dairy industry. Cow’s milk is nearly equal to soy milk in GHG/liter, partly because cows can eat byproduct foods (like cottonseeds and distillers grains). Furthermore not all animal products are equal, and some plant products are a problem as well. Finally, taking one intercontinental flight per year is just as bad or worse than eating animal products. If you are serious about wanting to really understand the subject, I would be happy to start a dialogue with you. I don’t claim to understand everything — climate change is a complex issue, but I want people to focus on things that really matter. I also agree that people will have to eat less animal products in the future than we do today. http://zacharyshahan.com/ Zachary Shahan Hello, I’m not sure where you ran across my article, but the full source article is here: http://www.chompingclimatechange.org/uploads/8/0/6/9/8069267/livestock_and_greenhouse_gas_emissions.pdf The authors were/are notable experts in the field: Dr Robert Goodland, the World Bank Group’s Environmental Advisor for over 23 years, and Jeff Anhang, a research officer and environmental specialist at the World Bank. More info also here: http://awellfedworld.org/globalwarming/worldwatch SpottedCow My main point is that not all animal ag is equal. Capper et al. (2009) showed that, in the past 60 years, US dairy farms have decreased CO2 equivalents per liter of milk by 2/3 (from 3.7 to 1.4) as they increased production per cow. Smedman et al. (2010) calculated that soy milk has about 25% less CO2 equivalents than cow’s milk; however, their data is for scandinavian cows, which would produce more CO2 per liter of milk than US cows so soy milk and cow’s milk are likely equal in the US. VandeHaar and St-Pierre (2007) showed that modern high-producing dairy cows can produce almost as much food for people from 1 hectare of land as if that land were used to grow grains and legume seeds for direct human consumption. Grains and legumes are more efficient than most other foods in a vegan diet, and certainly wine, beer, and chocolate are not efficient. For those of us who like to travel, how much we fly is a much bigger problem than what we eat. See commute_travel_product.pdf from the EPA website and climatechangeconnection.org/solutions/Airtravel.htm. The people who read your articles are probably like me. So if we eat a greener diet but still fly all over, we are the problem, no matter what we are eating. http://zacharyshahan.com/ Zachary Shahan Yes, there are certainly many sectors of society that must be changed in order to address global warming. No argument there. But to say that we shouldn’t address one issue until we address another issue is of course faulty logic. We do need to address all of them — food production, ground transport, air transport, electricity generation… SpottedCow I agree with eating less animal products, as per the current USDA guidelines. My main point was that much of the world uses inefficient animal ag systems. The animals produce GHG but little food for humans. The 51% value from the paper implies that the major thing we could do in the west is our diet. But the GHG contribution here would be much lower. Thus, I raise the issue of flying. Today I see young people who go vegan to be green, but fly all over the world, and then think the meat-eaters are the problem. Finally, I wanted to point out that you can’t lump all animal products together. Milk and egg production are much more efficient processes than growing muscle. We don’t gain very much by cutting them out. ConservationMatters April 2, 2014 Mr. Shahan; please take the one minute needed to read the following brief. At the end of the day, it’s all about Energy. Yet, America continues to WASTE over 70% of the energy it consumes. Our horrendous energy waste is everywhere! Municipalities, businesses, industry, offices, and SCHOOLS are the worst offenders. (1) 100’s of millions of lights burn unnecessarily every day and night.(2) We OverLight, OverHeat, OverCool, and OverDRIVE as if it doesn’t matter. (3) Over packaging is the norm, and recycling is inadequate. Our landfills are busier than ever. (Plastics are the cause of most cancers and therefore our most heinous polluter.)(4) Very few Americans minimize their driving; road congestion is commonplace. America’s incessant obsession with driving and road construction is the ultimate contradiction to sustainable living. Mass transit needs to be made FREE (we subsidize all kinds of ‘projects, why not one that helps everybody ! ), SAFE (have cops ride whenever needed. They can still be utilized elsewhere when needed.), CLEAN, & CONVENIENT(this is the hard part; requires intelligence.) Solar, Wind, Hydroelectric can only succeed when energy conservation is also utilized. Only our dwindling fossil fuel supply has the energy potential to support our waste and overuse. Fracking, Off-shore Drilling, Tar Sands, Nuclear Power; it’s OUR own dumb fault. The way to eliminate waste and reduce demand for energy is by using the economic impact of taxing energy. Crude oil must be Federally taxed at $160 per barrel(42 gal) and this ‘energy consumption tax’ be OFFSET by making Federal Income Tax begin at $60k. Only with a tangible and substantial dollar$$ consequence/reward will there be a plausible incentive to conserve energy. (Reward the ‘Prius drivers, cyclists, walkers, & mass transit riders. Let the Hummers and other gas guzzlers pay a fair price for their high energy consumption.) Global warming continues to rapidly increase with our persistent waste and overuse of fossil fuels. Our hedonist energy waste is culturally pervasive, flagrant, irresponsible, disgraceful, abominable, sinful, and suicidal ! Human extinction will be the reward for our failure to quickly and broadly implement renewable energy supplies and genuine conservation.

I have some posts at http://www.solidtechinc.com and http://www.mechatronictips.com steve meyer email@example.com david have you commented/blogged or written any material on comparing/contrasting living in Poland vs the USA, especially seeing you have been in CA, NC and FL… few of the most desirable locations in the USA? http://zacharyshahan.com/ Zachary Shahan I did this one (looks like i need to add the image again): http://zacharyshahan.com/7-environmental-lessons-from-living-in-europe/ But that was just ~1 year after I moved to Poland. Have another piece on in-the-home stuff planned for next Saturday on TreeHugger. These are my archives there: http://www.treehugger.com/author/zachary-shahan/ adamclark1 Zach, I tried reaching you on Facebook. No luck. I’d like to see your spreadsheet template as referenced in “It’s time to drive on sunshine” for evaluating electric cars and solar payback. I’m the VP of the Houston Electric Auto Assoc, and I know there are lots of Houstonians looking for this info. Thanks. theo I am looking for the most cost effective solution to this problem for a very cost-conscious school project: we want to power a motor with solar. The motor requires: 110 volts 180 watts 1.6 amps. So far the potential solutions look to cost about $750, which we cannot do. Before we scrap the project, I’d love to know if I am missing a possible solution. I could rent something for a few days, but I don’t even know how to do that. We are based in NYC. Thanks. StarReb Steve, Do you have some suggested sources for a “newbie” on info regarding off-grid solar systems for a whole house system? How does the Tesla Powerwall factor in systems now? Thanks, Mike Kim Diaz Have question about the blogging. mermaidinshade at gmail dot com Ken Howk Starting a renewable energy business. Hopefully I can get approval to be a Sun Power dealer, but if not who is a good alternative for commercial and residential panels? http://zacharyshahan.com/ Zachary Shahan Hmm. SunPower is definitely the leader in high-efficiency solar panels for home, but the companies that have been dominating the solar panel market due to lower cost are Yingli Solar, Trina Solar, and Canadian Solar. (All of these are Chinese companies, despite how it may seem. :D) Yingli has been having some financial problems, but it was the #1 solar panel producer in 2013 and 2014. I’d look into all of them. And good luck, btw! Christin Zenchenko I just saw your work for the first time today. Am writing something for PennEnvironment and up to my eyes In research on FRACKING, YOU DO A great job! Diane Christin Zenchenko Esser http://zacharyshahan.com/ Zachary Shahan Awesome! Thanks. 😀 Russell Zach, you might like to see this i3 that I tweaked out… ferrari red, after market front and rear spoilers, powder coated black wheels by Mak, and I dropped it an inch with new springs. Its a head-turner and so fun to drive… barely ever need the brakes with the regen, and I think its safer that way too. It eliminates the lag moving your foot from the gas to the brake since lifting from the gas starts the braking by itself. Good luck on your decision. http://zacharyshahan.com/ Zachary Shahan Sweet! 😀 Yes, one-pedal driving — think we need to write more pieces praising that.
