    Their PowerSheet cells contrast the current solar technology systems by reducing the cost of production from $3 a watt to a mere 30 cents per watt. This makes, for the first time in history, solar power cheaper than burning coal. These coatings are as thin as a layer of paint and can transfer sunlight to power at amazing efficiency.

Energy efficiency | The elusive negawatt | Economist.com - 0 views

  • IN WONKISH circles, energy efficiency used to be known as “the fifth fuel”: it can help to satisfy growing demand for energy just as surely as coal, gas, oil or uranium can. But in these environmentally conscious times it has been climbing the rankings. Whereas the burning of fossil fuels releases greenhouse gases, which contribute to global warming, and nuclear plants generate life-threatening waste, the only by-product of energy efficiency is wealth, in the form of lower fuel bills and less spending on power stations, pipelines and so forth. No wonder that wonks now tend to prefer “negawatts” to megawatts as the best method of slaking the world's growing thirst for energy.

    Energy efficiency is low hanging fruit in the clean energy movement. Low-grade waste heat may not have the allure of shiny solar panels or a row of wind turbines, but it presents an opportunity that is too good for Michael Newell, CEO of Ener-G-Rotors to pass up. The company is developing a product that generates electricity from low-grade waste heat.

  • Take a good look at panels that have been installed for several years and you will notice discontinuities and shiny areas where the components have been damaged and where the power production is reduced.

      There's an idea. Only once I've seen a paper on long-term performance of panels.
  • Though there are no visibly moving parts in a solar PV panel, there are many parts of the system where continuous chemical and physical reactions take place that can eventually lead to system degradation and failure.

      Makes sense. Roofs have no moving parts as well, yet we're always concerned of infiltrations.
  • Leaves and snow are particular nuisances for rooftop solar panels, but sand and bird droppings can be important in some areas as well.

    Solar photovoltaic (PV) cells are a popular and often discussed (see, for example Atlantic City Convention Center Plans Largest Solar Roof in U.S., 10% of U.S. Electricity From Solar by 2025, SF Passes Largest City Solar Program in U.S. (Finally), all of which were published within the past week) form of "renewable" or "green" energy, but a casual scratching of the surface knowledge that many people have about the technology reveals some troubling details.

    "What we'd like to do is to make Milwaukee become a national leader in growing fish by creating a large-scale production facility to grow 100 tons of yellow perch, which is a species which has kind of been in decline in the Great Lakes. We'd like to bring it back and satisfy the market for it and at the same time have an educational component so we can show the rest of the country on how they too can grow fish in the city," Bales says.

  • n aluminum can costs about a cent. Almost worthless, so it’s easy to toss it in the trash. It's like a magic trick, if you think about it. The thousands of stages in the manufacturing process, the material costs and the human stories, disappear into the air when we only have to spend a cent.   It’s how environmental catastrophes happen. We can’t see how unsustainable some products really are - because when they come in packs of 10 for a buck, who would be crazy enough to sell our planet off so cheaply? Separating price and value requires a shift in perspective. Things are often cheap because companies have figured out ways to externalize their true costs. Here's a look at what it really takes to make 10 everyday items we all use.

    Genetically engineered bacteria could make cellulosic ethanol cheaper to manufacture, researchers report. The finding could unlock more energy from the waste products of farming and forestry. Ethanol from cellulose, the kind of sugar in cornstalks and sawdust, is being promoted as an environmentally friendly alternative to fossil fuels, with the advantage that it does not use food crops such as corn as raw materials.

  • John McCain and more than a score of fellow Republicans called on the Environmental Protection Agency to scupper, or at least reconsider, the ethanol mandates passed in the last energy bill. The bill calls for a five-fold increase in U.S. ethanol production through 2022. President Bush reiterated the need for more “renewable fuels” in his Rose Garden climate speech last month.

Economic viability of small to medium-sized reactors deployed in future European energy... - 2 views

  • Future plans for energy production in the European Union as well as other locations call for a high penetration of renewable technologies (20% by 2020, and higher after 2020). The remaining energy requirements will be met by fossil fuels and nuclear energy. Smaller, less-capital intensive nuclear reactors are emerging as an alternative to fossil fuel and large nuclear systems. Approximately 50 small (<300 MWe) to medium-sized (<700 MWe) reactors (SMRs) concepts are being pursued for use in electricity and cogeneration (combined heat and power) markets. However, many of the SMRs are at the early design stage and full data needed for economic analysis or market assessment is not yet available. Therefore, the purpose of this study is to develop “target cost” estimates for reactors deployed in a range of competitive market situations (electricity prices ranging from 45–150 €/MWh). Parametric analysis was used to develop a cost breakdown for reactors that can compete against future natural gas and coal (with/without carbon capture) and large nuclear systems. Sensitivity analysis was performed to understand the impacts on competitiveness from key cost variables. This study suggests that SMRs may effectively compete in future electricity markets if their capital costs are controlled, favorable financing is obtained, and reactor capacity factors match those of current light water reactors. This methodology can be extended to cogeneration markets supporting a range of process heat applications.

  • The U.S. Energy Information Administration (EIA) today released the complete version of the Annual Energy Outlook 2010 (AEO2010), which includes 38 sensitivity cases that show how different assumptions regarding market and policy drivers affect the Reference case projections that EIA previously released in December, 2009. In addition to considering alternative scenarios for oil prices, economic growth, and the uptake of more energy-efficient technologies, the AEO2010 includes cases that examine the impact of changes in selected policies, such as the extension of existing policies that are currently scheduled to sunset as well as the sensitivity of natural gas shale production to variations in drilling activity and the size of the resource base.

  • nd in fact a few weeks ago in Spain we produced more energy from wind than we did from nuclear in one day
  • What is happening in Germany is that most of the modules that are being installed are coming from China and Japan and so on. So it is a kind of contradiction. So our enemies are using this and saying we are investing our taxes in order to give our money to the Chinese. Even in terms of investment, some investments are not coming from Spanish investors, but from Chinese or Japanese etc. So, unfortunately the situation is quite complex. 
  • So from October onwards there will be new legislation. So the big barriers in Spain are the new administrative processes, because for a normal citizen it is a nightmare to get a licence. The administrative procedures are absolute nonsense.

  • no-one could have perceived that we would be producing more energy with wind than we are with hydro or coal. Wind is now only behind nuclear and gas. This is really important – wind is about 10% of our electricity in Spain
  • We can predict that in Southern Europe, the cost of the production of a PV plant with be lower than the tariff by 2015.
  • When we don't need the subsidy we will see the market respond.

  • Ford Motor Company has developed an intelligent charging system that previews how its production vehicles will interact with the grid. The unnamed system enables all-electric and plug-in hybrid vehicle owners to restrict charging to when electricity prices fall below a certain threshold, or even “when the grid is using only renewable energy such as wind or solar power,” according to Ford.

Although not alone in its drive to capture this potentially valuable market, Ford’s strategy and product range reflects the market sentiments; primarily that there is no silver bullet.
