How a new kind of home which produces more energy than it consumes, can drastically reduce fuel bills and CO2 emissions. Governments around the world are scrambling to address the twin crises of our times—the recession and climate change—by investing in infrastructure and green energy projects. The Obama administration’s stimulus package, for example, contains billions in incentives for alternative power sources and energy-efficiency increases affecting millions of homes. The question is how to identify “shovel-ready” projects that can quickly deliver the economic boost and CO2 reductions we so urgently need. Rolf Disch, an architect and environmentalist in Freiburg, Germany, has an answer: houses that produce more energy than they consume.
“What if each house became a power plant, if it created even more energy than it used internally?” Disch, 65, first asked himself 15 years ago. To design that home, he built on the ideas of the “passive house” movement that started in Europe in the early 1990s. Instead of relying on the electricity grid for power, a passive house taps available energy sources—sunlight, the body heat of occupants, even the thermal gains created by ordinary domestic activities such as cooking, bathing and using electrical appliances. The building is well-insulated and airtight so it retains most of this energy and, through highly efficient heat-exchange ventilation technology, uses it to cool itself in summer and heat itself in winter. The houses are called “passive” because most of the power consumed is collected from ambient energy in the environment. When extra juice is needed, renewable power units supply it, like the solar array on the roof of the residential and commercial complex Disch built in Freiburg in 2004.
“I only ever had to switch on the heating once,” says Stefan Sattler, a 32-year-old lawyer who has rented a penthouse in the Disch-designed complex since October of 2007. Even then, Sattler only needed the extra heat—purchased from the local heating grid—for two or three hours. Since he and his fellow residents sell the surplus energy produced by the building’s solar panels back to the city’s utility provider at a profit, Sattler is one of the few people who opens his utility bills with real glee. He’s earning money from solar power rather than paying for oil or gas. The average unit in the Freiburg complex earns $5,075 a year this way instead of spending $4,625.
Passive homes can save consumers a bundle in fuel bills—and the planet even more in CO2 emissions. According to the German Passive House Institute (PHI), founded by physicist Wolfgang Feist, who co-created the passive house concept, energy consumption can be reduced by up to 90 percent compared to average homes, up to 75 percent compared to newer buildings. While an existing home uses some 160 kilowatt-hours in heating energy per square meter of living space (kwH/m2) annually, residences built to the passive house standard use a maximum 15 kwH/m2.
Paris — If you’re looking for a comprehensive resource for renewable energy installation figures, look no further: The Renewables Global Status report was released last week, and it provides a great snapshot of where and how renewables are being developed around the world.
The report was released by the Renewable Energy Policy Network for the 21st Century, also known as REN21, and it provides an upbeat picture for renewables, despite the murky outlook for the global economy.
The report was originally released in 2005. Since then, solar PV has grown by 60 percent annually, wind by 27 percent, solar hot water by 19 percent, according to the authors. In 2009, renewables made up more than half of investment in global power generation. And that’s with depressed oil and gas prices, lenders being very choosy about projects and individual consumers facing their own financial problems. Total investment in the industry was about $150 billion last year.
Other than the stellar investment figures during a slow year for most other industries, there’s not much surprising in the 2009 report. The industry continues to move along – increasingly in developing countries – driven largely by robust public policy. Where policy lacks, investment does too.
Perhaps the most important trend is the role of China in the global renewable energy market. According to the report, the country produces about 40 precent of solar PV panels, 30 percent of wind turbines and 77 percent of solar hot water systems globally. The Chinese presence will impact investment decisions of companies as they work to compete with “The China Price,” and decide where to locate manufacturing facilities.
Many organizations like the International Energy Agency and the Energy Information Administration put together yearly figures on renewables. But none do it quite as comprehensively and clearly as the REN21 folks do. It’s worth keeping around as a go-to resource for figures on the industry.
Here are some other highlights taken straight from the report about the various renewables sectors:
New Energy to Unveil World’s First-of-Its-Kind See-Thru Glass SolarWindow Capable of Generating Electricity
University of South Florida Research Foundation Grants New Energy Exclusive, Worldwide License for Technologies to Enable Commercial Development of SolarWindow(TM)
BURTONSVILLE, Md., Jul 20, 2010 (BUSINESS WIRE) — New Energy Technologies, Inc. /quotes/comstock/11k!nene (NENE0.53, +0.03, +6.00%) is pleased to announce that researchers developing its proprietary SolarWindow(TM) technology have achieved major scientific and technical breakthroughs, allowing the Company to unveil a working prototype of the world’s first-ever glass window capable of generating electricity in the upcoming weeks.
Until now, solar panels have remained opaque, with the prospect of creating a see-thru glass window capable of generating electricity limited by the use of metals and various expensive processes which block visibility and prevent light from passing through glass surfaces.
New Energy’s ability to generate electricity on see-thru glass is made possible by making use of the world’s smallest working organic solar cells, developed by Dr. Xiaomei Jiang at the University of South Florida. Unlike conventional solar systems, New Energy’s solar cells generate electricity from both natural and artificial light sources, outperforming today’s commercial solar and thin-film technologies by as much as 10-fold.
New Energy’s SolarWindow(TM) technology is under development for potential application in the estimated 5 million commercial buildings in America (Energy Information Administration) and more than 80 million single detached homes.
“We’re always keen to see innovations in our laboratories turn into meaningful commercial products,” stated Valerie McDevitt, Assistant Vice President for Research, Division of Patents and Licensing, University of South Florida. “We very much look forward to the commercial development of New Energy’s SolarWindow(TM) technology, which, if successful, could literally transform the way in which we view the use of solar energy for our homes, offices, and commercial buildings.”
Ere many generations pass, our machinery will
be driven by power obtainable at any point in the
universe. It is a mere question of time when men
will succeed in attaching their machinery to the
very wheelwork of nature.

Ready for another exciting competition in the world of prefab solar houses? Today the 2010 Solar Decathlon Europe kicked off in Madrid, Spain, marking the first time the competition has been hosted in Europe! Seventeen teams from around the globe are battling it out in the center of the city to see who has the most efficient solar powered and eco-friendly house. Just like the competition in Washington DC, the teams will be graded on their ability to minimize their energy use, innovative architecture and engineering, sustainability, and more. Read on for our exclusive photos and a first look at the most exciting houses in this year’s competition!
Above, the Fablab House from the Institute for Advanced Architecture of Catalonia is on their home turf for this competition and one of it’s most striking differences from the other houses is its departure from rectangular home. Solar panels completely cover the curvaceous roof and is built off the ground for a boost of natural ventilation
Please see this amazing article and its great pictures. The American entry is from last year, but it is still awesome. 2 things to note. This not being critical either. 1, building codes in many areas prohibit the construction of prefab homes. The reasons range from protecting unions, to cutting competition against builders, to bad experiences with crappy kits. 2, they are small compared to some standards. This is in part because they encourage people to live outside which is good for your health as well as encouraging socializing. But it is also the case that many people have gotten used way too much space for way to much STUFF. We are consuming the planet and we must stop.
The Sun is by far the largest object in the solar system. It contains more than 99.8% of the total mass of the Solar System (Jupiter contains most of the rest).
It is often said that the Sun is an “ordinary” star. That’s true in the sense that there are many others similar to it. But there are many more smaller stars than larger ones; the Sun is in the top 10% by mass. The median size of stars in our galaxy is probably less than half the mass of the Sun.
The Sun is personified in many mythologies: the Greeks called it Helios and the Romans called it Sol.
The Sun is, at present, about 70% hydrogen and 28% helium by mass everything else (“metals“) amounts to less than 2%. This changes slowly over time as the Sun converts hydrogen to helium in its core.
The outer layers of the Sun exhibit differential rotation: at the equator the surface rotates once every 25.4 days; near the poles it’s as much as 36 days. This odd behavior is due to the fact that the Sun is not a solid body like the Earth. Similar effects are seen in the gas planets. The differential rotation extends considerably down into the interior of the Sun but the core of the Sun rotates as a solid body.
Conditions at the Sun’s core (approximately the inner 25% of its radius) are extreme. The temperature is 15.6 million Kelvin and the pressure is 250 billion atmospheres. At the center of the core the Sun’s density is more than 150 times that of water.
The Sun is the most prominent feature in our solar system. It is the largest object and contains approximately 98% of the total solar system mass. One hundred and nine Earths would be required to fit across the Sun’s disk, and its interior could hold over 1.3 million Earths. The Sun’s outer visible layer is called the photosphere and has a temperature of 6,000°C (11,000°F). This layer has a mottled appearance due to the turbulent eruptions of energy at the surface.
Solar energy is created deep within the core of the Sun. It is here that the temperature (15,000,000° C; 27,000,000° F) and pressure (340 billion times Earth’s air pressure at sea level) is so intense that nuclear reactions take place. This reaction causes four protons or hydrogen nuclei to fuse together to form one alpha particle or helium nucleus. The alpha particle is about .7 percent less massive than the four protons. The difference in mass is expelled as energy and is carried to the surface of the Sun, through a process known as convection, where it is released as light and heat. Energy generated in the Sun’s core takes a million years to reach its surface. Every second 700 million tons of hydrogen are converted into helium ashes. In the process 5 million tons of pure energy is released; therefore, as time goes on the Sun is becoming lighter.
The chromosphere is above the photosphere. Solar energy passes through this region on its way out from the center of the Sun. Faculae and flares arise in the chromosphere. Faculae are bright luminous hydrogen clouds which form above regions where sunspots are about to form. Flares are bright filaments of hot gas emerging from sunspot regions. Sunspots are dark depressions on the photosphere with a typical temperature of 4,000°C (7,000°F).
The corona is the outer part of the Sun’s atmosphere. It is in this region that prominences appears. Prominences are immense clouds of glowing gas that erupt from the upper chromosphere. The outer region of the corona stretches far into space and consists of particles traveling slowly away from the Sun. The corona can only be seen during total solar eclipses.
The Sun appears to have been active for 4.6 billion years and has enough fuel to go on for another five billion years or so. At the end of its life, the Sun will start to fuse helium into heavier elements and begin to swell up, ultimately growing so large that it will swallow the Earth. After a billion years as a red giant, it will suddenly collapse into a white dwarf — the final end product of a star like ours. It may take a trillion years to cool off completely
Electromagnetic radiation consists of electrical and magnetic energy. The radiation can be thought of as waves of energy or as particle-like “packets” of energy called photons.
Visible light, infrared rays, and other forms of electromagnetic radiation differ in their energy. Six bands of energy span the entire spectrum (range) of electromagnetic energy. From the least energetic to the most energetic, they are: radio waves, infrared rays, visible light, ultraviolet rays, X rays, and gamma rays. Microwaves, which are high-energy radio waves, are sometimes considered to be a separate band. The sun emits radiation of each type in the spectrum.
The amount of energy in electromagnetic waves is directly related to their wavelength, the distance between successive wave crests. The more energetic the radiation, the shorter the wavelength. For example, gamma rays have shorter wavelengths than radio waves. The energy in an individual photon is related to the position of the photon in the spectrum. For instance, a gamma ray photon has more energy than a photon of radio energy.
All forms of electromagnetic radiation travel through space at the same speed, commonly known as the speed of light: 186,282 miles (299,792 kilometers) per second. At this rate, a photon emitted by the sun takes only about 8 minutes to reach Earth.
The amount of electromagnetic radiation from the sun that reaches the top of Earth’s atmosphere is known as the solar constant. This amount is about 1,370 watts per square meter. But only about 40 percent of the energy in this radiation reaches Earth’s surface. The atmosphere blocks some of the visible and infrared radiation, almost all the ultraviolet rays, and all the X rays and gamma rays. But nearly all the radio energy reaches Earth’s surface.
Particle radiation
Protons and electrons flow continually outward from the sun in all directions as the solar wind. These particles come close to Earth, but Earth’s magnetic field prevents them from reaching the surface.
However, more intense concentrations of particles from flares and coronal mass ejections on the sun reach Earth’s atmosphere. These particles are known as solar cosmic rays. Most of them are protons, but they also include heavier nuclei as well as electrons. They are extremely energetic. As a result, they can be hazardous to astronauts in orbit or to orbiting satellites.
The cosmic rays cannot reach Earth’s surface. When they collide with atoms at the top of the atmosphere, they change into a shower of less energetic particles. But, because the solar events are so energetic, they can create geomagnetic storms, major disturbances in Earth’s magnetic field. The storms, in turn, can disrupt electrical equipment on Earth’s surface. For example, they can overload power lines, leading to blackouts.
That is right the Sun creates all the energy on the Earth. Well, the Sun or its cousins because the heavy metals that we use for our version of “nuclear power” were created in Suns of the past that blew up. The oil, natural gas and the coal we burn are nothing but dead congealed plants and animals nurtured by the sun. Really think about it what is “natural gas”. The stink of the dead from the past. So why do we do that? We can get all the energy we need directly from the Sun? The point is that if the capitalist system can sell you bottled water then it surely can sell you petroleum products. http://en.wikipedia.org/wiki/Sun
~220 km/s (orbit around the center of the Galaxy)
~20 km/s (relative to average velocity of other stars in stellar neighborhood)
396.5±3.0 km/s[4] (relative to the cosmic microwave background)
The Sun is the star at the center of the Solar System. It has a diameter of about 1,392,000 kilometers (865,000 mi), about 109 times that of Earth, and its mass (about 2 × 1030 kilograms, 330,000 times that of Earth) accounts for about 99.86% of the total mass of the Solar System.[10] About three quarters of the Sun’s mass consists of hydrogen, while the rest is mostly helium. Less than 2% consists of heavier elements, including iron, oxygen, carbon, neon, and others.[11]
The Sun’s color is white, although from the surface of the Earth it may appear yellow because of atmospheric scattering.[12] Its stellar classification, based on spectral class, is G2V, and is informally designated a yellow star, because the majority of its radiation is in the yellow-green portion of the visible spectrum.[13] In this spectral class label, G2 indicates its surface temperature of approximately 5,778 K (5,505 °C; 9,941 °F), and V (Roman five) indicates that the Sun, like most stars, is a main sequence star, and thus generates its energy by nuclear fusion of hydrogen nuclei into helium. In its core, the Sun fuses 430–600 million tons of hydrogen each second. Once regarded by astronomers as a small and relatively insignificant star, the Sun is now presumed to be brighter than about 85% of the stars in the Milky Way galaxy, most of which are red dwarfs.[14][15] The absolute magnitude of the Sun is +4.83; however, as the star closest to Earth, the Sun is the brightest object in the sky with an apparent magnitude of ?26.74.[16][17] The Sun’s hot corona continuously expands in space creating the solar wind, a hypersonic stream of charged particles that extends to the heliopause at roughly 100 astronomical units. The bubble in the interstellar medium formed by the solar wind, the heliosphere, is the largest continuous structure in the Solar System.[18][19]
The Sun is currently traveling through the Local Interstellar Cloud in the Local Bubble zone, within the inner rim of the Orion Arm of the Milky Way galaxy. Of the 50 nearest stellar systems within 17 light-years from Earth, the Sun ranks 4th in mass.[20] The Sun orbits the center of the Milky Way at a distance of approximately 24,000–26,000 light years from the galactic center, completing one clockwise orbit, as viewed from the galactic north pole, in about 225–250 million years.
I will try to post more green wash meditations but let us consider how bad things can get here at times. This is an event I was actually unaware of and it’s coolness is pretty high.
May 6, 2008: At 11:18 AM on the cloudless morning of Thursday, September 1, 1859, 33-year-old Richard Carrington—widely acknowledged to be one of England’s foremost solar astronomers—was in his well-appointed private observatory. Just as usual on every sunny day, his telescope was projecting an 11-inch-wide image of the sun on a screen, and Carrington skillfully drew the sunspots he saw.
Right: Sunspots sketched by Richard Carrington on Sept. 1, 1859. Copyright: Royal Astronomical Society: more.
On that morning, he was capturing the likeness of an enormous group of sunspots. Suddenly, before his eyes, two brilliant beads of blinding white light appeared over the sunspots, intensified rapidly, and became kidney-shaped. Realizing that he was witnessing something unprecedented and “being somewhat flurried by the surprise,” Carrington later wrote, “I hastily ran to call someone to witness the exhibition with me. On returning within 60 seconds, I was mortified to find that it was already much changed and enfeebled.” He and his witness watched the white spots contract to mere pinpoints and disappear.
It was 11:23 AM. Only five minutes had passed.
Just before dawn the next day, skies all over planet Earth erupted in red, green, and purple auroras so brilliant that newspapers could be read as easily as in daylight. Indeed, stunning auroras pulsated even at near tropical latitudes over Cuba, the Bahamas, Jamaica, El Salvador, and Hawaii.
Even more disconcerting, telegraph systems worldwide went haywire. Spark discharges shocked telegraph operators and set the telegraph paper on fire. Even when telegraphers disconnected the batteries powering the lines, aurora-induced electric currents in the wires still allowed messages to be transmitted.
“What Carrington saw was a white-light solar flare—a magnetic explosion on the sun,” explains David Hathaway, solar physics team lead at NASA’s Marshall Space Flight Center in Huntsville, Alabama.
Now we know that solar flares happen frequently, especially during solar sunspot maximum. Most betray their existence by releasing X-rays (recorded by X-ray telescopes in space) and radio noise (recorded by radio telescopes in space and on Earth). In Carrington’s day, however, there were no X-ray satellites or radio telescopes. No one knew flares existed until that September morning when one super-flare produced enough light to rival the brightness of the sun itself.
“It’s rare that one can actually see the brightening of the solar surface,” says Hathaway. “It takes a lot of energy to heat up the surface of the sun!”
Above: A modern solar flare recorded Dec. 5, 2006, by the X-ray Imager onboard NOAA’s GOES-13 satellite. The flare was so intense, it actually damaged the instrument that took the picture. Researchers believe Carrington’s flare was much more energetic than this one.
The explosion produced not only a surge of visible light but also a mammoth cloud of charged particles and detached magnetic loops—a “CME”—and hurled that cloud directly toward Earth. The next morning when the CME arrived, it crashed into Earth’s magnetic field, causing the global bubble of magnetism that surrounds our planet to shake and quiver. Researchers call this a “geomagnetic storm.” Rapidly moving fields induced enormous electric currents that surged through telegraph lines and disrupted communications.
:}
Here is a really good article on it. I am posting a chunk of it not covered above.
As it happened, a second member of the Royal Astronomical society (another Richard, this one the otherwise-obscure Richard Hodgson in London), also saw the flare and so proved conclusively that there was nothing wrong with Carrington’s equipment. By the time this was realized, though, it was already pretty clear that something truly odd had happened—something rattled the Earth’s atmosphere the next day, as described above.
The connections between light, magnetism, and electricity were still incompletely understood in 1859 (James Clerk Maxwell would not entirely coincidentally publish his tour de force on the subject over the next few years), but Michael Faraday had already discovered the Law of Induction. Shorn of mathematics, it provided for the creation of electricity if a piece of metal cuts across a magnetic field or the field instead cuts over the metal. That was the connection between the strange readings at Kew and the telegraphic events around the world. The enormous auroras were symptomatic of huge fluctuations in the Earth’s magnetic field, and those fluctuations were playing across the world’s 200,000 kilometers of telegraph wire. By analyzing the directions followed by wires and comparing them to the effects that occurred at their stations, it was even possible to develop a rough idea of how the fluctuations had flowed around the planet.
Though the correlation between sunspots and the fluctuations of Earth’s magnetic field had already been discovered by Edward Sabine, this was the first really solid evidence that the Sun could reach out to the Earth with something other than light or gravity. Conservative by nature, Carrington himself didn’t commit to a connection between his flare and the electromagnetic storm, but now we know that the Sun throws off coronal mass ejections consisting of protons and electrons (the first having been observed in 1971). We even know for sure that the 1859 event was caused by one, despite the more than a century since it occurred; protons and electrons expelled by the Sun move quickly, but not anything like the speed of light, so that accounts for the delay between Carrington seeing his flare and the beginning of the auroras.
The clincher can be found on one of the charts linked to previously. There’s a “fishhook” shape (marked with an arrow labeled “D: Solar Flare Effect”) in the bottom trace. That’s called a magnetic crochet, and it’s the characteristic bump in the Earth’s magnetic field caused by X-rays from the coronal mass ejection ionizing part of our atmosphere. X-rays move at the speed of light, outpacing the charged particles following them—and it takes eight minutes to get from the Sun to the Earth at that speed. As closely as can be told from the relatively crude instrumentation that drew the track (hours are listed at the top of the same chart), the crochet occurred within the same time frame as Carrington’s closely timed 11:18 observation of the flare. So we have both a delayed effect from the slow stream of charged particles and a high-speed effect moving at light speed; a coronal mass ejection fits the bill exactly.
