I will be attending Sustainable Cleveland 2019 later this week. It has given me a renewed interest in renewable energy and has really been great motivation to learn more about my city.

The summit will be a gathering of more that 600 people from different walks of life in Cleveland, all trying to figure out what we need to do in order to become a leader in various fields of sustainability. The 2019 part of the title refers to the Cleveland 30 year from now, when all of the areas of sustainability will hopefully have been achieved. These sustainability initiatives could include:

• Renewable energy production
• Advanced energy (infrastructure)
• Advance material fabrication and advanced manufacturing operations
• Sustainable, local food sources
• Green buildings (LEED certifications)
• Stringent environmental policies, especially to protect our water source, Lake Erie
• Sustainable Business Practices

So what can we do as a group of non-policy makers to actually drive any change in this city? A question I'm not completely sure of the answer. At the most basic level, I think this summit will give the citizens and drivers of change in the city a chance to tell the administration what they think. In fact, the entire summit is being hosted by the mayor, Frank Jackson, so I am guessing that's exactly what he's looking for. Beyond the basics, there is a methodology being implemented known as Appreciative Inquiry; I'm not into organizational behavior, but from what I've read it's a popular method. The leading researcher in this field, David Cooperrider, will also be present at the summit to lead and guide us. I was surprised to later learn that Dr. Cooperrider is a sitting professor at my alma mater, Case Western Reserve University. From what I have learned about the method so far (which in all honesty seems a bit touchy-feely to me), it is about bringing people together while they are still excited about a prospective idea, instead of after problems have developed and that same group is only trying to fix the problem. It has proven successful for many groups thus far so I am eager to learn more about it.

Although this was the first time they decided to host such a summit, the organizers required an application for entry, to ensure people who were signing up were serious about their pledge to attend (the summit requires a 3 day commitment). I thought including some excerpts of my application would help illustrate why I think attending a summit like this is important (Warning: I was very interested in attending, so I felt it necessary to toot my own horn a bit. You've been warned) :

Describe what draws you to this summit.

I understand that a 10 year plan is only as good as the people that are writing and later following it. I want to be an integral part of the planning progress so I can help shape a future city that is sustainable and one that I can continue to be proud of. I am interested in meeting others that are passionate about moving Cleveland  towards a future that is sustainable, successful and forward-looking. The people at this summit will be the leaders of the next phase of Cleveland's evolution and I would like to start working with them as soon as possible.

What unique aspects will you bring to the summit (education, life experience, etc.)?

I currently write a blog that discusses electrical engineering and renewable energy. I write on topics relating to my profession (analog electrical engineering), my generation (Gen Y) and I tie it into content about emerging renewable technologies. I also have a unique perspective, being a student that left the area for a job after college, thereby contributing to the “brain drain” that has affected much of Cleveland; I have since been one of the few that has returned (in 2008) so that I could help contribute to the city and pursue my passion at a company that is a leader in the measurement industry. My work at Keithley Instruments has given me insight into the needs of renewable energy producers and allowed me to work with some of the finest engineering minds in Cleveland.

I feel that I bring a fresh perspective on the technological aspect of building a sustainable Cleveland. As someone who works in an industry that serves renewable energy and as someone who aspires to work more directly in the renewable energy sector, I feel that I can help define where Cleveland will be able to best capitalize on new technologies and strong business opportunities. These will drive the future growth of Cleveland as both an economic hub and as a model for hosting sustainable and eco-conscious companies.

What do you think are Cleveland’s biggest strengths or best assets?

I believe that the students graduating from local Universities will be the foundation upon which the next phase of Cleveland will be built. Enticing them to stay in Cleveland and encouraging them to create new companies will generate revenue and jobs in Cleveland. The technology and companies that are created will drive local development and help bring in more residents and investment. Furthermore, I believe the Universities that are producing these students are an asset and that they should be assisted in post-graduate retention and building businesses out of commercialized research efforts.

A second more obvious but yet untapped resource is Lake Erie. In terms of energy, I believe Lake Erie can produce a great deal of clean and sustainable power for residents in Cleveland and surrounding areas. From a sustainability perspective, the availability of fresh water must be considered and protected, as this will become an increasingly scarce resource as the world warms. Additionally, the wildlife and food sources the lake provides must be taken into consideration when planning for a more sustainable city and region.

What do you envision for Cleveland in the year 2019?

I envision a vibrant job market based on renewable energy companies that have sprung up over the past 10 years. More importantly, I see educational and research hotbeds such as Case Western Reserve being used as a launch point for multiple new industries and technologies. I see renewable energies being harvested from Lake Erie in the form of wind turbines and wave harvesting. I see axillary industries such as test & measurements adding even more to local economies and highlighting what Cleveland has to offer the world. I see tight-knit communities encouraging conservation and recycling and teaching these concepts in schools. I see programs in place to help every city have affordable recycling. I imagine local and regional governments encouraging restructuring and consolidating existing infrastructure as opposed to creating new sprawl. I see those same governments encouraging outside investment in the newly reconstructed and consolidated areas and in the new companies that have helped revitalize it . And hopefully, I see my own renewable energy company creating products that change the way we consume energy or how we cleanly produce it for use in energy efficient devices.

I feel that if nothing else, I will get the opportunity to meet others interested in sustainability and renewable energy in Cleveland. That alone could provide a great foundation for forming companies and coalitions later to help advance the city towards a sustainable future. On the other hand, I am hopeful that our work using Appreciative Inquiry will help lay a groundwork for where the city needs to go and what we need to do as a community to achieve our goals. I know there will be many planned follow up activities and I plan on discussing them more on here later. I would hope that my albeit limited audience might help to publicize the actions the city will take in the future.

Are you attending the Sustainable Cleveland 2019 summit? If you are, please let me know! If not but you have ideas that you think I should try to talk about while I am there, please let me know in the comments. I am interested to share what ideas I already have and if I can bring more voices than my own to the summit, I think it could be beneficial for everyone.

In a down economy, there is always focus on low cost. Job cutting, project re-definition, scaling back expenses, finding new sources of parts, all of these actions can lead to lower costs and help businesses stay alive in crappy economic climates. I think that the average (electrical) engineer can't but help to let this mentality creep into other parts of their lives. In fact, I think the best engineers enter the profession and excel with this mindset. This revelation about engineering penny pinchers may have been stumbled upon by myself after being accused of being overly-thrifty a time or two. I don't mind it though; I think maintaining a mindset of low cost is good for my work life and my personal life.

I have been on my own personal finance journey ever since I bought a house in the middle of a recession. I have been a regular reader of Get Rich Slowly, a fantastic blog about personal money issues, getting out of debt, smart money planning and tips on living a simple and frugal life. One of my favorite books suggested by JD has been The Ultimate Cheapskate's Road Map to True Riches. It is full of interesting ideas to save money in non-traditional areas and generally living a simple and fulfilling life. If you've never read it, I highly suggest it. I also suggest to my engineering friends out there to consider how you can refocus your engineering efforts to match these principles. In his writing Jeff Yeager lists "6 golden rules for ruling your gold", but I think they have everyday practical implications in engineering. Here is how I translate them for a thrifty engineer:

1. Live within your means at thirty, and stay there. -- I translate this idea as staying on budget for a project. A simple idea but many projects fail to do so. However, this also assumes you have a realistic budget in the first place. Allotting $10 for test equipment when you don't have any and you plan to work on high speed signals is not a realistic way to start a project.
2. Never underestimate the power of not spending. -- Again, this is my translation but I would say this would be to cut out extraneous costs in a project. True, this sounds a bit scrooge-like, but I feel if I was bootstrapping my own company, this would be the only way I would operate. Ten years down the road you will remember the feeling of accomplishing your goal of releasing a product more than you will remember the t-shirt and mug you got commemorating it.
3. Discretion is the better part of shopping. -- I'll speak more on this later, but the idea is to understand when you are buying a valuable product or service and when you are just being "sold" on something. It also means you have to understand the intricacies of what you are buying. From an analog engineering perspective, I think of this as buying a switching converter or something similar. Sure, you know you need to change the voltage supplied to a part of a circuit, but unless you know why you do or don't need the latest and greatest buck converter, you might end up paying too much (for something you won't necessarily need...could a linear regulator do the trick?).
4. Do for yourself what you could have others do for you. -- Design services are available for just about any task in engineering.If you were desperate enough, you could farm out every task in a project to a separate engineering firm that would piecemeal put together your project for you (READ: outsourcing). While it's nice to use this service every once in a while to help speed up a portion of a project you are not an expert with, the time it takes to learn what has been done for you will often outstrip the time you save. Then if something breaks later no one knows how to fix it and you must pay the same design firm to help you again.
5. Anyone can negotiate anything. -- This is my favorite of the six golden rules and the one I have been taking most seriously lately. My attitude has been, "What is the downside to asking for a discount from a vendor?" If you are the customer, the most they will tell you is that they cannot swing any discount; at that point I thank them for their time and tell them I will get back to them after talking to some competitors. In a recession, people are eager to make a sale and are willing to lose some of their margin to do so. Don't think of it as costing them money, think of it as gracing them with your business in a down time.
6. Pinch the dollars, and the pennies will pinch themselves. -- Paying $0.10 more per resistor when you are only buying 100 may have huge dividends. It could reduce the error in a circuit by orders of magnitudes. This is a small expense. Paying $100,000 for an oscilloscope that can measure 80 GHz when you really only need 10 GHz (still a little too RF-y for my tastes) could save you a significant amount of money and raise your overall margin for a product. Making money decisions based on need instead of "ooo-look-at-this-ery" can help project teams, companies and individuals have more rewarding payoffs at the end of a project.

Adding to the cheapskate stew and something briefly mentioned in point 3 above is discretion when buying a new product. I believe engineers are well suited for this mindset and that it stems from a slight mistrust of marketers and salesman. This is neither vituperation against engineers or any salesmen or marketers I have known, just that it is a general trend I have seen. I believe it is the result of encountering both sides of the sale. From the product designer perspective, there is often tension with marketers and salesmen when there is lack of communication. If the salesman talks to a customer and tells them that a new product can jiggle a widget 3x faster than the competition, the customer may purchase the product thinking it will always be jiggling at 3x of FluxCorp's latest product. But if the product can only sometimes and under the correct conditions jiggle that fast, well, there will be some problems; when the salesman relays back to the engineer that the customer is unhappy with their new product, arguments and finger pointing may ensue. On the other side of the sale, engineers often encounter sales forces descending upon them to encourage using their sub-widget in the new widget jiggler. If the salesman can supply a portion of the design to your new product then they will share in your success, because every new product made is a sale for them (albeit only a fraction of your product's final sale price).  However, engineers sometimes encounter marketers and salesman (on the "being sold to" side of things) that may provide some "stretching" of the truth of a sub-widget's ability. In either case, I believe that being a part of selling to others and being sold to helps hone engineers' ability to sniff out when they are being sold something (as opposed to buying something because they want/need it). This is both something learned in engineering and a quality that some of the best engineers possess.

Yet another thing that drives engineers towards thriftiness is the nature of their jobs. If you look at an engineer and compare them to a scientist, there are some interesting distinctions. First, engineers are responsible for bringing products to market. This means that whatever technology they are using (oftentimes first discovered by scientists) must be viable on a large scale and must be done efficiently. If a scientist determines that a capacitor can hold more energy if you tap on it with your finger 1000 times before applying a voltage across it, that might be a brilliant (albeit completely fake) discovery. The engineer has to worry about how that capacitor can be sold at a reasonable price (in relation to the demand of the marketplace) and how to possibly produce millions of finger-tapped capacitors as fast as possible. Most importantly, the engineer and the company he/she works for is judged on the difference of the cost and the selling price (margin). More often than not the marketplace will be the one determining the price, so the only option for making more money is to reduce the costs in producing the product. A scientist may have external funding which allows for time to discover the newest technologies that will be later implemented; there is less direct influence on the success of the technology by near-term funding (though I know grant-writing is no picnic). The direct payoff and re-investment of profit from a successful product introduction influences how engineers operate. The thrifty engineers are successful because they can have the money they save go directly back into their next product.

A counter argument to being a (true) cheapskate is when it comes to quality. Many times in work and in life there can be significant savings from buying a quality product the first time. An example might be buying a high quality, variable temperature soldering iron (maybe even with an auto shut down). Compare that to buying a piece of junk Radio Shack soldering iron that you happen to leave on after working on your Wurlitzer. The former can last you many years and will perform well and help you solder many different products throughout its lifetime. The RS soldering iron burns out in less than a year (perhaps due to negligence, we'll never know) and is not capable of soldering even the largest components properly. In this example there is money saved by not having to purchase another RS soldering iron and there is time saved while working on a project. So while I say that I am a cheapskate, I try to take all costs--including time--into account when purchasing something.

So answer the question Chris. Are engineers naturally cheapskates? After looking at the facts here it is pretty obvious that no, engineers are not naturally cheapskates; rather, they are often in a position to pick up money-saving skills while working on engineering issues and are well liked by management if they succeed in saving money. Also, if you happen to have some innate cheapness you will be at an advantage when starting out in engineering. Some of the people I have encountered in engineering have shown me the benefits of reducing costs in their personal lives and always knowing as much as possible about what they are buying so they can make make the best possible decision.

How about you? Are you a cheapskate? You definitely don't have to be an engineer to be one. Do you find that engineers are naturally more thrifty? Please let me know in the comments or take the poll below!

Last month, I had a not-so-nice commenter remark that my last post on blogging keeping me going through a recession was a waste of time. He or she went on to remark that they didn't have a job and they were obviously looking for some help. While I can't say I condone their harsh tone and unnecessary crudeness (I know, I know, it's the internet), I do empathize with their jobless situation.

So today's post is going to be on some ways (and notably some non-traditional ways) to go about getting a job and hopefully getting through this recession. Here is the big disclaimer though: I don't know how many of these techniques work. I am basing them on my own ideas and experience and some are just brainstorms. Let's start from the top with the most traditional methods of finding a job and work our way down to the silly and intriguing ideas. On with the show...

1. Online job searches/classified ads -- 4% success rate, 10% unemployment. Do the math and consider this one to be a non-option.
2. Networking -- Ahh man, I know I'm not going to get this point across like I want to, but there are so many ways this is important. I actually had a digital designer I worked with a few years back sit me down and explain the importance of networking, and I STILL didn't get it. In fact, for a long time, I was infuriated by the idea that just who you know might get you a job, as opposed to what you know. But here's what it comes down to: there are a ton of people who can do your job. In fact, there are a lot of people out there who can do your job better and possibly cheaper than you (think China). However, you are the person who was in the right place at the right time, with the right skills, the right charisma and the right contacts. Everything else you start learning the day you start your new position. Networking takes time, though, and you need to start it before you lose or leave a job. It means that you are friendly with the people you work with and you're actively keeping in touch with people you used to work with.  If you haven't been doing that, call up a former co-worker and see what they're working on; you might find something interesting and you get to maintain a relationship easily.
3. Vendors -- Yes, this still falls under the category of networking, but in a different way. Vendors, for those of you who do not know, are people trying to sell you (an engineer or scientist) stuff. They can be salesmen, application engineers, marketers, you name it. If they're trying to get you to buy what their company has to offer...they're vendors. They are also in the unique position of trying to sell stuff to other people in your industry; therefore, they know a lot of people doing a lot of stuff that is similar to your job. If I lost my job tomorrow, my stack of vendor business cards would be the first thing I would reach for. Call up some of them and see what trends they see in the industry. Ask for a place to look for your next gig. If you don't deal with vendors on a regular basis, try other people you interact with daily who have contact to the outside world (maybe the UPS or FedEX delivery person?).
4. Get something published -- You don't need to publish a paper in IEEE or Nature to get noticed by people. Sure, those first two magazines will get you noticed by a lot of people, but you really only need one. Think smaller. Write a letter to an editor in EETimes or EDN (two of my favorites).  I know whenever I see a letter to the editor, I am usually curious to what kind of expertise that person has and what industry they work in. Make sure when people look you up they know how to find you and that you have some good examples of your work.
5. Blog Comments -- The traditional gatekeepers to knowledge have started to transition. Whereas engineers and scientists might have only had a few sources of news in the past, blogs now offer an alternative in myriad forms; be it a day-in-the-life format or an aggregation of smaller news stories that might interest an engineer or scientist, information is available everywhere these days. These outlets also provide new ways to find others interested in the same stuff as you. If you see a comment from someone on a blog that intrigues you, try to strike up a conversation with them or see if that person has their own website (usually a link from their name). Try contacting the writer of the blog and see how receptive they are to talking to their readers (hopefully very). Blogs provide information and a new method of meeting people online. As with many of the other items on this list, try the less traveled places first; don't try writing to an administrator of slashdot if you are interested in tech stories. Look for some smaller blogs (maybe from people linking their own blogs on slashdot) and try to contact them.
6. LinkedIn -- One of the best ideas I have ever heard in a job hunt is "informational interviews" (I first read it in the classic "What Color Is Your Parachute"). Basically, you call up someone and ask them about what they do, their industry, job trends and anything else you think might be relevant to a position.  Sometimes people will pick up on the fact that you're in the market for a job, but other times they might not and you just have an interesting conversation. The problem I always had though was how to get an interview. The best way would be through those contacts I mention when I talk about networking...but the real problem is when you don't have any contacts either. Then you are in a bit of a tighter spot and you need to get creative. One technique suggested by a friend that had worked for me to look up people on my LinkedIn network; extra points if they work somewhere I think I would like to work. Then once I know their name I try to figure out what their company email might be (usually they're standardized at companies) and try to email them to request if you can call them for an informational interview. Sure it's a little sneaky, but I think it's OK if you're genuinely interested and not just trying to use them as a contact. Sometimes you won't get a response, sometimes you'll get a confused response, sometimes you get a grouchy person and sometimes you get a person who doesn't mind taking a few minutes out of their day to talk to an inquisitive person. I'll let you look up informational interview questions for yourself, but go through the interview, keep it brief and ask if they wouldn't mind passing you a name of someone else to talk to; if they do, be sure to thank them profusely afterward. If they don't pass you a name... thank them profusely anyway. If nothing else, you will get a good conversation and some more information about an industry that interests you. Note: I always tried to email people first before an informational interview. You could always try and call someone out of the blue (call a front desk, ask for them) and ask for an informational interview; they usually will be confused by this abrupt request. Refer to this technique (that I learned from some sneaky recruiters) only if you really would like to talk to someone and they are non-responsive to email (remember, there might be a reason).
7. Work For Yourself -- My friend Pat recently came up with a great idea while he looks for work. He has been helping me out with my (still) broken Wurlitzer, taking the old schematic and putting it into a modern CAD program. He gets the experience of using common, open-source tools and I get some free labor to help me with my board. He also mentioned learning other software while he is looking for work. I see this sprouting into other opportunities too; if you are working on a new piece of software, you're likely going to go to discussion boards for help.  You might even get involved in the development of the open-source tools, all of which can provide great experience and great contacts. If nothing else, you can put hobbies on your resume that are relevant to your potential job (the only hobbies that should ever be listed in my opinion). Showing an employer that you are passionate about your chosen field (i.e. willing to go home and do the same stuff you just did for 8-12 hours that day) really can make you stand out in a crowd.
8. Work For Free -- Starting to get into ideas that I'm really not sure would work. Offer to work somewhere for free. This could be considered an "internship" or whatever you want to call it. You'd basically be working for two things (besides no money): contacts and experience. The latter might be limited, especially if you are working somewhere with a sensitive security policy. However, if you offer your services for free, you will get to meet people and that could be worth more than anything else. Remember, you want to look in the non-standard places for work, so don't waste your time begging for a job at this place. If they don't want to pay you to start with, they probably won't want to pay you in the future (at least not in a recession). Instead, talk to everyone you meet and make them want to help you. This idea might be the most difficult of the bunch but if you can pull it off (namely getting the internship to start with), it might have the best chance of success.
9. Guerrilla marketing -- Are you particularly good at CAD programs? Have you created a novel circuit that you think might interest an employer? Have you made a website about analog electronics? Use non-standard ways to stand out; however, make sure you do this at non-standard times. Don't walk up to a recruiter at a job fair and hand him a circuit diagram with your signature on it. Instead, find out who is in charge of the hiring process (non-HR) and send it to them. Better yet, use the idea in number 5 and figure out who that person is and send the circuit diagram as a thank you to each person you talk to along the way. As for the CAD designer, make your business card out of a circuit board or something else novel like that. Passively advertise that you are in the job market. The "Parachute" book mentions putting it on your answering machine that you are currently looking to have your contacts help your searching project. If you have a website or a facebook profile, make sure it is well known (your front page or your default status message)that you are in the market for a job and some of the best characteristics you can offer. Shameless? Nope, just a good way to get your name out there.
10. Walk in a front door -- This idea was the inspiration for this post and also the most ludicrous of the bunch. What would happen if you dressed up in your best suit and walked into an office and asked for a meeting with Mr. BigGuyInCharge? Sure, you'd need to figure out that person with some sneaky or not-so-sneaky methods prior to walking in there; but if you did it right, this technique has a small small chance of working. It's like the in person cold call. Most managers won't have anything to do with it, but that one time it might work that makes it all worth it. I'd suggest any of the above methods before this one, but since it was the inspriation for this post, I figured I had to include it.

The recurring theme for all of these ideas is stepping outside your comfort zone and to try approaches to non-standard job paths. You don't have to try the most extreme of these ideas (like walking into an office asking to talk to a manager), but you might have to pick up a phone and call a bunch of people. Or you might need to develop some new skills on your own before applying for a new job. If you keep trying hard and keep trying different things (other than online applications), you'll eventually find something. If you are lucky enough to be working right now, keep an eye out for friends and colleagues and help them when you can. Good luck to all and leave any other ideas you might have in the comments.

I glanced at my natural gas bill today while cleaning up the house and was a little shocked at myself. I pride myself on being better than most on conservation (at least cognizant of it) and my usage was quite high. That was last month and I can only imagine this month will get worse. And yes, I do live in a rental house right now (with an energy efficient house in my near future), but that's the case for a lot of people, especially lower income. So I got to thinking, what will stop people from using so much energy in their frosty, great northern homes?

The answer is, of course, money. It always has been. But now we're in a climate where the costs are beginning to rise so fast that people who sat dormant before will begin to take action. In fact, this will also likely move people in all economic groups to take action; the most important of these being the middle- to lower-income groups. Why? Because costs like heating are a larger percentage so there will be a more voluminous cry from the masses for cheaper energy (not that we don't love our green friends, pushing the renewable energy agenda and buying recycled elephant dung paper as Christmas gifts for family). Hopefully more people clamoring for energy efficient devices and alternative fuels will push us towards a tipping point (which I incorrectly identified as a singularity), where renewables become the norm and cost of energy will drop due to the abundance of natural energy, waiting to be converted. So as prices continue to increase--and the temporary drop in gas prices is undoubtedly temporary--the push from most people will be towards a more sustainable future.

How about you? Have you felt the need to push for more conservation lately solely on energy costs? Let me know in the comments.

My friend Cherish over at Faraday's Cage is where you put your Schroedinger's Cat sent me an article on solar power approaching the cost of coal (generated electricity). It's a great article and it quotes Ray Kurzweil so I'm automatically a fan. However, I have no doubt in my mind that it WILL hit this price point (~$1/watt), it's just a question of when.

The real thing I want to touch on and get responses to is: What happens when solar energy is cheaper than coal?

I think there will be gradual uptake by the large energy companies (most already have dipped a toe in the shallow end for solar power). Even large scale consumers will start to put renewable energy on their balance sheets, assuming it is cheaper. But then what? Business as usual? Am I allowed to keep my lights on all night, even if it is silly to do so? I'm confident that not only will solar be cheaper than coal, but over the long term, it will be MUCH cheaper because you get more lifetime out of a panel or a solar thermal system than you do with a lump of coal. So will prices go down from the power company? I'm not so sure about that one as I'm guessing they'll want to pass their "investment costs" down to the consumers.

Another facet to this idea is whether or not consumers will start to take on the burden of their own energy generation. Will there be a deficit in the north and a surplus in the south? Will there be a grid efficient enough to transfer this energy transcontinentally? Will there ever be a storage mechanism that is feasible for all of the energy we could potentially harvest from the sun (I just heard about this idea and thought it was really cool)? Or is the individual power generation scheme doomed to fail because there is still an energy broker in the middle (the power company) for all those times when the sun isn't shining (and the wind isn't blowing if that becomes a more efficient source of power also).

If power consumption continues to get cheaper and everyone adopts a renewable stance on it, will the environment actually improve? Will there be as much focus on conservation, both in reducing power needed in devices and total consumption per capita (reducing our individual "carbon footprint")? Will the cheap energy of the future fuel the next boom and pull us out of the doldrums of this dumb recession?

So many questions. So so many and we still haven't even found out if we CAN make it cheaper than coal yet (cautiously optimistic here). Renewable energy will be translating to big money for some people over the next ten years and that means lots of conflict. What do you think will happen when/if solar becomes cheaper than coal?
