Around the world on solar power alone - 0 views

  •  
    A brief article about the project PlanetSolar, led by Raphael Domjan, and its efforts to prove that solar power is a viable and wise alternative energy approach, especially in the shipping industry. Domjan has overseen the construction of a solar-powered catamaran with 5,300 square feet of solar panels and hopes that its voyage across the world will encourage a re-examination of fuel efficiency and popularize solar technology.

Walmart says thin (solar) is in - 1 views

  •  
    "When Walmart announced on Monday that it would install 15 megawatts' worth of solar arrays on as many as 30 of its stores in California and Arizona, it set out to shape the solar market in more ways than one." Good or bad? Part of me feels like this is fine, "great I'm glad they're helping out." But part of me is also very nervous about this. I dont know if I like the idea of Walmart "green coating" their business. I think we're planning on talking about this in class Thursday.

Solar cells thinner than wavelengths of light hold huge power potential, Stanford resea... - 1 views

  •  
    Promising research on the science side of environmentalism. Solar panels that are thinner than the wavelength of light allow for longer "captivity" of the proton, and thus "absorb more than 10 times the energy predicted by conventional theory." This relates to our ENVS 160 unit regarding the limits to growth. More technology = changing limits, once again. The article ends with a slightly unsettling note however: Fan, one of the researchers is quoted, "Where this will have a larger impact is in some of the emerging technologies; for example, in organic cells." Oh technology, are you a friend or foe?

First-Ever Solar Project Approved on Public Lands in Nevada - 0 views

  •  
    Alternative energy on public land, and from the ocean: http://atlanticwindconnection.com/?page_id=37 The solar farm is a government initiative, the wind farm is a private business initiative. I'm relatively econ-illiterate, but I have a hunch that this might make a difference. Those who have a better understanding, what could this mean about the respective success of alternative energy projects?

Energy Storage - Other Side of the Renewable Coin - 0 views

  •  
    People love talking about wind and solar. For good reason, too. Geothermal, hydro, and other renewable energy sources are valuable, but ultimately only sun and wind (and mostly sun) have the heft necessary to power the nation. That leaves us with two big problems! Night time and windless days. Enough power has to be produced to meet minimal needs at any given time, which is related to the idea of baseload production. When the wind is really moving, or the sun is particularly bright, wind and solar plants can generally overproduce. But all that is for naught when night rolls around, unless things like pumped hydro or NaS batteries fill in the gaps. Of course, there is always nuclear. Tempting as it is to say you can either argue for nuclear, or read about Japan, the nuclear option is still on the table - largely because of its ability to provide constant energy. But if wind and solar are indeed more desirable, storage is an absolute must, and worth being informed about.

On Clean Energy, China Skirts Rules - NYTimes.com - 0 views

  •  
    At face value it appears China is trying to improve its clean energy reputation. By becoming the World's leader in wind turbine and solar panel exporters, it looks as though the country is paying attention to the environmental crisis at last. Though it may appear like this industry is doing good for the world, however, it is wrecking havoc in the political and economic spheres. Therefore this article, juxtaposed to Maniates' "Individualization" raises interesting questions regarding the limitations of "good intentions" in helping the environment. Sometimes doing good in one sense can be detrimental in another. "China Takes Lead" also illuminates the complexities regarding clean energy technologies due to their economic ramifications and political biases.

Future of Technology - 'Artificial leaf' makes real fuel - 1 views

  •  
    A silicon solar cell was recently developed at MIT. This "artificial leaf" breaks down water molecules into oxygen and hydrogen gas, which can be used as a fuel source. I just thought it was really cool. And here's a video! http://www.youtube.com/watch?v=LEEhxk-CiOQ&feature=player_embedded

Ancient Italian Town Has Wind at its Back - 1 views

  •  
    Tocco de Casuaria, Italy is a small town that has installed wind and solar energy and is now producing a 30% surplus of energy that they are able to sell to the electricity company. With this money, the people of Tocco have been able to increase the wages of street workers as well as town maintenance. The financial benefits of using renewable energy, versus a deep concern for the health of the natural environment, has been the driving force for this town and other towns across Europe to adapt this new technology. This conversion is more difficult in the U.S. because the government does not provide a great incentive for people using renewable energy as far as a cash return from excessive energy production.

Why Energy Efficiency Does not Decrease Energy Consumption - 2 views

  •  
    Here's one of those studies that apparently shatters our intuition: energy efficiency won't help reduce the use of energy??  Read on for the reason why, all about the "rebound effect" and indirect vs. direct energy consumption.  Again, looks like sustainability requires that we address the bigger picture.
  •  
    This brings up some concerns I have about the environmental movement in general. I often feel like our emphasis is in the wrong place. Even before it was acceptable to question environmental activism (without being labeled a no-good capitalist hippie-hater) I have felt uncomfortable with some of the campaigns and goals out there. Alternative Energy is a key one for me. I dont think we have an energy source crisis, I think we have an energy use crisis. I dont just mean "energy use" in terms of petroleum (CO2 emitting) energy either. Even if we find alternate energy sources (like the solar panels article I posted on the LCENVS220 group), or more efficient machines/lights, we still will expect the same (or more) amount of work to be done from external energy sources. I think we should focus on realizing what energy already exists in our natural systems and learn to synchronize with that to accomplish our goals, instead. This, I think, will address broader (and dare I add more important?) problems than CO2 emissions.

Leasing the Sun - 0 views

  •  
    An example of how alternative economic models (or even longstanding ones, applied to a new product) can make things like clean energy more feasible for people, even if the initial costs of installation, production, or what not remain the same. Important to remember that how you move things of value around matters, perhaps just as much as what the values are in the first place? If nothing else, the importance of looking at things in a new way, allowing for more options.
  •  
    For the record, if I understood Richard Bettega of facilities correctly, a lease-based program similar to this is what is behind our current solar panels on Pamplin. If a wealthy enough investor can be found, we'll be starting up another program here on South Campus or above the swimming pool. I'm not sure on the details, but they're along the lines of this.

U.S. Military Orders Less Dependence on Fossil Fuels - 1 views

  •  
    Now this is very interesting, if not particularly surprising. The US military has begun pushing for the development of renewable energy sources that can be readily deployed in battlefield situations and remote locations where traditional fossil fuels are prohibitively scarce. Trucking fuel to outposts and encampments in Afghanistan can be dangerous: "...for every 24 fuel convoys that set out, one soldier or civilian engaged in fuel transport was killed. " It is also extremely expensive. The US military buys fuel for around $1 a gallon, but shipping that fuel can easily cost hundreds of dollars per gallon. Taking those transport costs into account, the high initial costs of investing in renewable energy are put into perspective. The US navy has begun to experiment with ships that run on electricity at lower speeds, as well as jets that use mixtures of conventional and bio-fuels. It is likely the "experts" say, that development of these technologies for military use will lead to more affordable civilian versions.

Human Battery - 4 views

  •  
    This is straight out of the matrix - you know how the whole AI system runs of humans producing energy like batteries? These guys are seriously looking at doing just that. This story comes from GlobalPost, a new site that has great international reporting (when a lot of big papers had to fire their journalists as the industry started to decline, GP picked a lot of their international folks up as freelancers, so they developed a good set of connections around the world fast). They're doing a series on power and energy around the world, "Powerland", which this is a part of. Very cool news organization. In a new twist in the progress of the global energy system, Japan is now looking to reduce its energy dependence on Nuclear Power (a source so many other places are looking to for reducing their energy dependence on oil, coal, etc...) So the company featured in this video comes in with an interesting mix of waste diversion/energy production at the same time. The little, marginal bits of energy thrown about when ever anyone does anything - taking a step, talking on a phone, sitting down and chilling - is harnessed to power things in its surroundings. It is sort of like using exercise equipments rotations to generate energy, which some colleges have gotten major press for. I know the military was also looking at putting something in the soles of boots that would create energy when compressed, so that marching or walking could actually power some of a soldier's personal electronics. There are no numbers to see how scalable this is, but looking at the energy margins is interesting. They do add up - one step is nothing, but if you're in Tokyo and there are millions of collected steps all the time, that is a lot of energy-producing floor vibration. One has to wonder as to how serious an alternative this sort of technology is to other types. Almost like being able to paint solar panels onto things, and just take advantage of wherever the sun hits. Its almost desperate, b
  •  
    For a different thing to pay attention to, listen to the street activist (I think - not clear what the source is) message at the very beginning of the video. Interesting the stance Japan seems to be taking, at least within some parts of its culture, in response to the Fukushima incident.
  •  
    I noticed that the Powerland series on GP is being sponsored by Shell, which raises some interesting questions. Multinational energy corporations may be turning to energy alternatives because they know that oil is going down the proverbial drain. Paying attention to where companies like Shell, BP, and Chevron-Texaco might yield some worthwhile information about our energy future.

Rebounding - back to Jevon's again. - 0 views

  •  
    The above article is the Break Through Institute's semi-recent report on the Jevons' Paradox, which I posted additional links to here and debated in class. For the record, the report is favorable. Also for the record, I have not read it completely, and am not laying down final judgment. However: I promised Jim I would respond to this at some point. I still hope to. In the meantime, this is worth musing over (if the link doesn't work, I have the PDF). https://files.me.com/jgkoomey/0aqqfm I really appreciate Break Through and the dismantling of environmentalism's sacred cows, but I'm concerned about this one. Many of their other critiques and analysis seem to have the empirical evidence, but I have yet to be convinced by what I've seen here. Obviously it is a long report, and I have not gotten to read through it entirely, but so far I remain unconvinced. I think they're thinking about the problem in the right way (the economy is a complex social, political, and economic system, it does defy basic models and equations, and if the emergence idea continues to hold up it is a right environment for them) and I really enjoy reading their analysis, but I remain unconvinced by the numbers. Our economy is not composed in such a way that energy is a primary limiting factor to production, which would surely deaden the effect, among other theoretical threats to the idea on both a micro and macro scale. Politically, efficiency measures will continue to allow solar energy and other alternative competitors to carry more weight than they do now, allowing us to free ourselves from the need for energy intense liquids or solids like coal, gas, and oil in favor of less "compact" energy sources. Break Through Institute offers some excellent political analysis, and their efforts at getting outside and away from the usual political roadblocks and antics are appreciated. But I wonder if they

    Obviously, its not my expertise either, and I'm woefully ignorant in all this ultimately. But their credentials don't seem to be in deep energy analysis and research, and one academic report where I do find Jesse Jenkins (of BTI, who helped write that report and is an energy expert) still encouraged energy efficiency measures (http://www.brookings-tsinghua.cn/~/media/Files/rc/reports/2009/0209_energy_innovation_muro/0209_energy_innovation_muro_full.pdf). I'm not bold enough to lay down final judgment, but I'm going to need a lot more convincing. BTI makes a lot of convincing arguments that I really like - so far, this hasn't been one of them. But like I said, I'm still reading. And trying to get a handle on what Shellenberger, Nordhaus, and Jenkins have under their belts in terms of economic, versus political (when the two are even seperable), analysis. If there is other stuff worth reading in that regard, I'd love to get my hands on it.
