Barack Obama’s Energy Policies – Please note that his Energy Policies and His Climate Policies are on one page

John McCain just does not get it. The Energy situation we are in and the Climate situation we are in are one and the same thing. For now let me say that in debate and in arguementation, when someone lists every possible answer they can think of, I think that they don’t know what they are talking about. That was John McCain’s approach. Obama’s policies are brief, pointed and focused.

The Obama-Biden comprehensive New Energy for America plan will:

     

  • Provide short-term relief to American families facing pain at the pump
  • Help create five million new jobs by strategically investing $150 billion over the next ten years to catalyze private efforts to build a clean energy future.
  • Within 10 years save more oil than we currently import from the Middle East and Venezuela combined.
  • Put 1 million Plug-In Hybrid cars — cars that can get up to 150 miles per gallon — on the road by 2015, cars that we will work to make sure are built here in America.
  • Ensure 10 percent of our electricity comes from renewable sources by 2012, and 25 percent by 2025.
  • Implement an economy-wide cap-and-trade program to reduce greenhouse gas emissions 80 percent by 2050.

ENERGY PLAN OVERVIEW:

Provide Short-term Relief to American Families

• Enact a Windfall Profits Tax to Provide a $1,000 Emergency Energy Rebate to American Families.
• Crack Down on Excessive Energy Speculation.
• Swap Oil from the Strategic Petroleum Reserve to Cut Prices.

Rammed Earth

Ramming earth to create walls is at least as old as the Great Wall of China. It is really quite similar to adobe and cob techniques, in that the soil is mostly clay and sand. The difference is that the material is compressed or tamped into place, usually with forms that create very flat vertical surfaces. Modern rammed earth typically utilizes heavy mechanized equipment to move and compress the material . The walls are normally at least a foot thick to give enough bulk to be stable and provide the thermal mass for comfort. It is best to apply insulating material to the outside of the building to keep the interior temperature constant. The interior surface can be finished in a variety of ways, from natural oil to more standard surfaces. Rammed earth houses tend to have a very solid, quiet feeling inside.

Do It Yourself


Rammed Earth

We are Bill & Stephen Betzen, a father and son team who started the planning process in 2004 to build a rammed earth home in Dallas, Texas by 2009.  We are on schedule. We want to share research we have done and make connections with similarly interested Do It Yourself (DIY) people also interested in rammed earth construction and benefits.

Our home is planned to be a 2400 sq ft, 2 story home with a covered balcony and porch surrounding the home. The ground floor earthen walls will be 2 ft thick with 18″ thick walls above the second floor. The goal is a home that will be as cool as possible in the hottest Dallas summer. With a home fully surrounded by both a shaded porch and a shaded balcony, as well as many trees, we hope the worst Dallas summer sun will never heat the thermal mass of the rammed earth walls. Combined with a ventilated, reflective metal roof over insulation, we hope that annual air-conditioning needs will be greatly reduced if not totally eliminated.

Our research shows rammed earth construction to be the most simple, environmentally responsible method for building the thermal shell of a home.  It will be a strong, quiet, healthy, termite-free, fire-resistant, comfortable home, one weighing 300+ tons and lasting many generations. It will save thousands of dollars annually in utility and maintenance costs along the way. 

Stephen’s mother and maternal Hungarian ancestors were born in, built, and lived in rammed earth homes for hundreds, if not thousands of years. They speak fondly of the quiet, year-around comfort of their rammed earth homes. We will simply add about 3-5% cement to the mixture, with a reflective, ventilated roof, and extra shade for the Dallas heat.

Continue to explore what is already online about rammed earth with www.google.com or with some of the following links, including the web ring at the bottom of the page linking with similar web pages.

  1. At http://www.rammedearthhomes.com/ you will find Quentin Branch’s pages describing the work he does in Arizona with rammed earth.

  2. You can find research done in 2004 in Del Rio Texas relating to the cooling qualities of rammed earth in an article linked online at http://www.toolbase.org/techinv/techResources.aspx?technologyID=144. It is the research by John J. Morony titled “Logged Data for Heat Wave, Del Rio, Texas, 31 May – 2 June 2004.”  It shows the superior ability of rammed earth to stay cool, even in direct sun in a heat wave, when compared to cement brick or adobe construction.  With our plans we need to know what happens when you keep these walls in the shade.

  3. How To Build a Rammed Earth House is a 1973 article published in Mother Earth, written by John O McMeekin about the home he had build 25 years earlier of rammed earth, and continued to live in at that time.  It appears he still lives there now but we are attempting to verify that at this time. His utility bills would be very interesting to compare with his neighbors in similar sized homes.

Clean Energy Summit – This thing has been so widely publicized that no one knows it’s going on

I have to admit that if not for Peak Oil and Rueters, I would not have known that this was even going on.

 http://www.iht.com/articles/ap/2008/08/20/business/NA-US-Energy-Summit.php

Business leaders: Make renewable energy cheaper

:}

MY TAKE ON THIS IS MAKE TRADITIONAL ENERGY MORE EXPENSIVE BY TAXING THE LIVING SHIT OUT OF THEM TO PAY FOR ALL THE DAMAGE THEY DO TO THE ENVIRONMENT – oh never mind.

LAS VEGAS: Representatives from Google Inc. and General Electric Co. said Tuesday that widespread use of renewable energy in United States would be possible — if it were cheaper.

Renewable energy options will remain “boutique” industries unless their costs are cut to make them competitive with coal and other widely used power sources, said Dan Reicher, director for climate change and energy initiatives at Google.org, the company’s philanthropic arm.

Reicher spoke to a group of politicians and energy experts at the National Clean Energy Summit in Las Vegas. The meeting’s attendees said they hope to develop a national energy agenda to take to the Democratic and Republican parties at their upcoming conventions.

“There’s a whole set of factors that go into the ultimate cost of energy,” Reicher said after announcing a plan for Google to invest more than $10 million to develop “enhanced geothermal systems” technology to generate energy from rocks deep below the earth’s surface.

Google’s project replicates traditional geothermal systems deep below the Earth’s surface by circulating water through hot rock and running the steam through a turbine that generates electricity.

“These are all high-capital-costs projects,” Reicher said.

One by one, speakers at the meeting touted the benefits of various energy-related initiatives, including how large-scale solar power could generate thousands of jobs and why wind power could lessen America’s dependence on foreign oil. Extending tax credits, establishing caps on carbon emissions and modernizing the nation’s electricity grid were also ideas that speakers said would be crucial to building a “green” economy.

New York City Mayor Michael Bloomberg said the energy discussion was timely, and he criticized presidential candidates Barack Obama and John McCain for not having a real debate about energy.

Texas oil baron T. Boone Pickens also presented his plan to develop wind energy to generate 20 percent of the nation’s electricity, then use natural gas to power cars until hydrogen or plug-in electric cars become widely available.

“I don’t see many people from my party,” said Pickens, a Republican. “I’m making new friends, and that’s good.”

Thank you for your interest in the Clean Energy Summit. Web registration for the summit is now closed. We will be able to accommodate walk-up registration at Cox Pavilion as capacity allows.

Industry leaders, scientists, policy experts, citizens, and the media will gather in Nevada at the national summit hosted by the Center for American Progress Action Fund, U.S. Senator Harry Reid (D-NV), and University of Nevada, Las Vegas, to chart a course for our nation’s clean energy future. This is a pivotal opportunity to focus on defining a policy agenda that accelerates the development of renewable energy, energy-efficiency technologies, and robust clean energy markets in Nevada, the nation, and the world.
Developing a Clean Energy Future for Nevada, the Nation, and the World

Nevada is at the epicenter in the debate of how America should generate and use energy in the future. Nevada has abundant clean energy sources such as solar, wind, geothermal, and efficiency technologies that could be developed to meet its future energy needs. The question is whether Nevadans—and all Americans—will shift to a clean energy economy that creates less expensive and more efficient energy, cleaner air, clean energy markets, and the creation of good new jobs that strengthen and grow our economy in Nevada, the nation, and the world.

We owe it to our children and grandchildren to protect the air they breathe and our nation’s great outdoors. Nevada has the opportunity to do that and lead the nation in a clean energy revolution by developing clean, renewable energy and efficiency technologies that will meet the state’s current and future energy demands.
Once again, America can lead the way. Developing new technologies will result in a robust clean energy economy our country can be proud of while creating good-paying jobs and diversifying our economy while not polluting our air.
This is our vision for America’s future. And the National Clean Energy Summit is a pivotal opportunity to help get us there.

The University of Nevada, Las Vegas is committed to increasing energy efficiency and to significantly reducing energy consumption through its energy management systems, recycling programs, and turf reduction efforts.  Our goal is to make the National Clean Energy Summit carbon neutral.

5 Solar Solutions

By Sean Leviashvili (07/28/08)

The Greatest Green Gadgets Ever

Some companies are struggling to go green, but rumor has it Toyota (TM) is going greener.

Japanese business paper the Nikkei reported earlier this month that the company plans to install solar panels on the redesigned Prius in 2009. The solar panels will provide two to five kilowatts of electricity to power utilities like air conditioners and radios.

Sales for the Prius are booming, especially in light of rising gas prices and the growing go-green trend. But if you aren’t ready to give up your gas guzzler, or simply can’t afford a $25,000 car, there are other ways you can get in on the solar craze.

Take a Look!

It’s in the Bag:


Chargers:
With an internal rechargeable battery, the Solio Classic charger acts as a hybrid giving you the option to connect to a home outlet or accept energy from the sun. The Solio can charge multiple gadgets including an iPod (AAPL), cell phone or digital camera. Check out the range of models ($79.95-169.95) at solio.com. Depending on the amount of sunlight, the Solio charger is capable of charging your gadget in under two hours.

Bags:

To charge on the go, invest in a solar backpack or messenger bag. According to Krissie Nagy, a sales and marketing representative from Voltaic Systems, an hour of direct sunlight will yield 1.5 hours of full cell phone use, or 3 hours of iPod play. Voltaic bags come with eleven different adaptors, including the latest Samsung charger, along with a car charger socket that covers adaptors not included.

Different bags have different charging potentials, and the devices you plan on charging should influence your purchasing decision. Charging a laptop, for example, is only possible in bags yielding at least 17 watts of electricity, such as the Voltaic Generator, available at voltaicsystems.com for $599.

Solar Jackets:
The Ermenegildo Zegna designed solar powered jacket charges devices right in your pocket. But this luxury doesn’t come cheap. The price: $995. According to the company’s official website, www.zegna.com, the jacket uses solar cells on the detachable neoprene collar, and powers devices at 5 or 6 volts, so it can charge your cell phone or iPod, but nothing larger.

AT HOME

Solar Water Heating:
Installing a solar water heating system costs between $5,000 and $8,000, says Gary Trainer, professional engineer for Solarplex in San Antonio, Texas. The installation process requires solar panels and a separate water tank, which works with anti-freeze and your home’s original water tank to produce hot water. The system, Trainer says, can cover 60 to 80% of your total water heating needs. And, while the initial purchase is costly, the long-term payoff is substantial. “After about eight years, you’ll really see the value in the system,” Trainer says. “At that point, the system will basically pay for itself.”

Solar Pool Heating:
With solar pool heating, you can extend your swim season by months. Depending on the size of your pool, buying and installing a solar pool-heating system costs anywhere from $2,000 to $10,000. According to the eere.gov, a branch of the Department of Energy’s website that focuses on energy efficiency and renewable energy, the cost of heating your pool with solar power runs from $7 to $12 per square foot.

Solar pool heating can save hundreds of dollars each year, and according to Trainer, this system has the greatest payoff of all solar heating systems. “The most expensive installment is the conventional grid type stuff, where you use solar power to reduce the energy your in-house utilities use,” Trainer admits. “But it’s not difficult to install a [solar] heating system for your pool for three or five thousand dollars, and the payout is great, it’s about two to four years.”

Solar heating systems all require solar panels (amount will vary based on the system), and a prior consultation to decide if solar power is right for you.

“There are certain conditions where it is just impractical,” Trainer says. “Trees are usually the number one reason, along with space limitation, and limited access to the sun.”

Pueblo, CO, USA: Colorado State University-Pueblo to Install 1 Megawatt PV System

Colorado State University-Pueblo soon will be the home of a solar electric system in excess of one megawatt, one of the largest such systems for an education facility in the United States. Under this innovative arrangement with Black Hills Energy (formerly Aquila) and BP Solar, the system is estimated to contribute more than 10 percent of the University’s electricity needs. Installation of the ground-based solar array will begin in July with full operation scheduled for late this fall.

The University will purchase the electricity generated by the solar array from BP Solar, who will install and operate the system. Black Hills Energy will purchase the solar on-site renewable energy credits generated from the system from BP Solar. The system will be constructed on the east side of campus between the physical plant complex and the softball fields on a strip of land that could not easily serve any other purpose.

“We view this as an extension of the commitment the University and the CSU System have made to renewable and sustainable energy,” said CSU-Pueblo President Joseph Garcia. “Because this solar array will be visible from new facilities being constructed to support our new athletic programs and the planned development on our eastern campus border, it will serve as a strong statement about the University’s commitment to supporting sustainable energy resources.”

“We are proud to be able to bring large-scale solar energy to Pueblo,” said Mary Shields, vice president of global sales and marketing for BP Solar. “The CSU-Pueblo campus is the perfect place to demonstrate the clean, efficient power that solar can provide to communities throughout Colorado and other parts of the U.S.”

Garcia added that the new system supports Governor Ritter’s New Energy Economy to make Colorado a hub for solar energy and supports Black Hills Energy’s effort to bring more solar energy to Colorado. As part of its Solar Rebate Program, Black Hills Energy will provide a $200,000 upfront rebate incentive for the installation of the solar system. The program helps Black Hills Energy meet Colorado’s Renewable Energy Standard, which requires that five percent of Black Hills Energy’s electricity sales be generated from renewable sources.

“Black Hills Energy is excited to be a part of this project and about the solar energy contribution this system will provide CSU-Pueblo,” said Gary Stone, Black Hills Energy vice president for Colorado electric operations. “Combined with the Black Hills Energy Solar Rebate Program, biomass and wind resources already in use, the CSU-Pueblo solar system builds on Black Hills Energy’s commitment to renewable energy for the communities we serve in Colorado.” With new facilities being brought on-line during the next six months, including a new $11.2 million student recreation center, CSU-Pueblo estimates the completed project will generate savings in utility costs and help absorb the cost of increased demand. Garcia said the project is a winning venture for all three partners.

“In short, this project will help control the University’s utility costs as prices and usage increase, promote the use of sustainable resources, help satisfy Black Hills Energy’s state mandates, and allow BP Solar to bring a major solar project to Southern Colorado,” Garcia said.

Smart Growth Advocates (SGA), a local non-profit, connected the partners last year. “Assembling the combined talents of a team of this caliber ensured results which exceeded expectations. Our goal was to highlight the effectiveness of public-private partnerships to deliver concrete sustainable solutions, and we are elated with the result,” said Vickie Massam, SGA President.

July 24, 2008Tempe, AZ, USA: First Solar to Build 10 MW Solar PV Power Plant for Sempra Generation

First Solar will build a 10 megawatt photovoltaic power plant for Sempra Generation near Boulder City, Nevada. First Solar will design, engineer and construct the turnkey PV power plant and will provide monitoring and maintenance services for the plant over its lifetime. Sempra Generation will be the developer for the project, and will own and operate the PV power plant once completed.

Construction began in July, and the 10 MW PV power plant is expected to be completed by the end of 2008. The solar modules to be deployed in this ground-mount project will be produced at First Solar’s manufacturing facility in Perrysburg, Ohio.

“Sempra Generation has a proven track record for successful energy resource development and we are pleased to work with them to bring additional renewable electric generation to the region,” said Mike Ahearn, chief executive officer of First Solar.

The 10 MW PV power plant will be adjacent to Sempra Generation’s existing El Dorado combined cycle natural gas plant. By co-locating this new PV power plant with existing infrastructure and the associated interconnection and transmission facilities, Sempra Generation will maximize their land and transmission. As a result, the impact to the immediate environment is minimal and the project completion timeline will be shorter. The PV power plant will serve customers in California and the Western United States.

“This new solar project is another step in Sempra Generation’s long-range plan to emerge as a leading renewable-energy developer,” said Michael W. Allman, president and chief executive officer of Sempra Generation. “The combination of Sempra Generation’s experience in developing power-generation projects in the region with First Solar’s expertise in advanced, thin-film photovoltaic solutions is a natural fit. ”

First Solar explains that it is a cost leader in the solar PV industry, driven by an advanced thin film semiconductor manufacturing process. At the end of 2007, over 300 MW of First Solar PV modules had been installed worldwide and First Solar expects to ship 420 to 460 MW of PV modules in 2008. Together with its project partners, First Solar modules have been deployed in several of the largest ground and rooftop PV power plants in the world.

Energy Efficient Clothes Dryer – Well there is one but it makes too much sense

Ok so you probably know what I am going to say so don’t rush me. Here is the conventional wisdom:

 http://www.consumerenergycenter.org/home/appliances/dryers.html

Unlike most other types of appliances, clothes dryers don’t vary much in the amount of energy used from model to model. That’s why clothes dryers are not required to display EnergyGuide labels. They’re also not listed in the ENERGY STAR®’s database.

But that doesn’t mean that the amount of energy used by clothes dryers isn’t important. A dryer is typically the second-biggest electricity-using appliance after the refrigerator, costing about $85 to operate annually.

Over its expected lifetime of 18 years, the average clothes dryer will cost you approximately $1,530 to operate.

Right now, all dryers on the market work the same – they tumble clothes through heated air to remove moisture. Engineers are working to develop dryers that use microwaves to dry clothes, but they’re not yet being sold. (One problem still to be overcome is metal rivets and metal zippers, which don’t microwave well.)

Electric vs Gas

All dryers use a small electric motor to turn a large drum that tumbles the clothes placed inside it. All of them have an electric fan, which distributes heated air. There are however, two ways to create the heat needed to efficiently dry clothes – using either gas or electricity.

Electric dryers use heating coils to supply heat. Most electric dryers operate on 240-volt current, twice the strength of ordinary household current. If your laundry area is not equipped with a 240-volt outlet, you must have one installed.

Gas dryers use a gas burner to create heat, but otherwise they operate the same as an electric dryer. Your laundry room must have a gas hookup, with proper connections and safe venting of the gas’s exhaust, in addition to an electrical outlet.

The connections you have in your laundry room will probably dictate which style you use. If you have both gas and 240-volt connections, consider that gas dryers cost more to begin with – approximately $50 more than the comparable electric model. But in most areas gas dryers will cost less to run over their lifetime. Generally speaking, the cost of electricity needed to dry a typical load of laundry is 30 to 40 cents, compared to 15 to 20 cents if you use gas.

The energy efficiency of a clothes dryer is measured by a term called the energy factor. It’s a rating somewhat similar to miles per gallon for a car – but in this case, the measure is pounds of clothing per kilowatt-hour of electricity. The minimum energy factor for a standard capacity electric dryer is 3.01. For gas dryers, the minimum energy factor is 2.67, and, yes, the rating for gas dryers is provided in kilowatt-hours, even though the primary source of fuel is natural gas.

 

Buying Smart

Consider these tips if you’re looking to buy an efficient clothes dryer:

  • Check for the highest energy factor number when comparing different models. Remember that there are two costs to an appliance – the initial purchase price, and the cost of operating that appliance over the many years you own it.
  • Know whether your laundry room has gas or electricity hookups. If you need to add a gas line and a vent to operate a gas dryer, you may spend more on adding the hookup than you’ll save with the cheaper operating cost of gas.
  • Look for a clothes dryer with a moisture sensor that automatically shuts off the machine when your clothes are dry. Not only does this save energy; it reduces wear and tear on clothes caused by over-drying.

The best dryers have moisture sensors in the drum for sensing dryness, while most only estimate dryness by sensing the temperature of the exhaust air. Compared with timed drying, you can save about 10 percent with a temperature sensing control, and 15 percent with a moisture sensing control.

  • Look for a dryer with a cycle that includes a cool-down period, sometimes known as a “perma-press” cycle. In the last few minutes of the cycle, cool air, rather than heated air, is blown through the tumbling clothes to complete the drying process.

It’s Your Money

Here are ways to cut the amount of energy and money you spend drying clothes:

  • Locate your dryer in a heated space. Putting it in a cold or damp basement or an unheated garage will make the dryer work harder and less efficiently.
  • Make sure your dryer is vented properly. If you vent the exhaust outside, use the straightest and shortest metal duct available. Flexible vinyl duct isn’t recommended because it restricts the airflow, can be crushed, and may not withstand high temperatures from the dryer.
  • Check the outside dryer exhaust vent periodically. If it doesn’t close tightly, replace it with one that does to keep the outside air from leaking in. This will reduce heating and cooling bills.
  • Clean the lint filter in the dryer after every load to improve air circulation. Regularly clean the lint from vent hoods.
  • Dry only full loads, as small loads are less economical; but do not overload the dryer.
  • When drying, separate your clothes and dry similar types of clothes together. Lightweight synthetics, for example, dry much more quickly than bath towels and natural fiber clothes.
  • Dry two or more loads in a row, taking advantage of the dryer’s retained heat.
  • Use the cool-down cycle (perma-press cycle) to allow the clothes to finish drying with the residual heat in the dryer.

Solar Water Heaters – Why not it’s free

Not the system the Sun. There are so many Solar Water Heaters available now that it is embarressing. Anyone who owns their own home and doesn’t install one is an Energy Hog. Tankless water heater owners are given a pass.

http://en.wikipedia.org/wiki/Solar_hot_water

Solar hot water

 Solar Hot Water refers to water heated by solar energy. Solar heating systems are generally composed of solar thermal collectors, a fluid system to move the heat from the collector to its point of usage, and a reservoir or tank for heat storage and subsequent use. The systems may be used to heat water for home or business use, for swimming pools, underfloor heating or as an energy input for space heating and cooling and industrial applications.

In many climates, a solar heating system can provide a very high percentage (50% to 75%) of domestic hot water energy. In many northern European countries, combined hot water and space heating systems (solar combisystems) are used to provide 15 to 25% of home heating energy.

In the southern regions of Africa like Zimbabwe, solar water heaters have been gaining popularity, thanks to the Austrian and other EU funded projects that are promoting more environmentally friendly water heating solutions.

Residential solar thermal installations can be subdivided into two kinds of systems: compact and pumped systems. Both typically include an auxiliary energy source (electric heating element or connection to a gas or fuel oil central heating system) that is activated when the water in the tank falls below a minimum temperature setting such as 50 °C. Hence, hot water is always available. The combination of solar hot water heating and using the back-up heat from a wood stove chimney to heat water[2] can enable a hot water system to work all year round in northern climates without the supplemental heat requirement of a solar hot water system being met with fossil fuels or electricity.

Evacuated tube collector

Evacuated tube collectors are made of a series of modular tubes, mounted in parallel, whose number can be added to or reduced as hot water delivery needs change. This type of collector consists of rows of parallel transparent glass tubes, each of which contains an absorber tube (in place of the absorber plate to which metal tubes are attached in a flat-plate collector). The tubes are covered with a special light-modulating coating. In an evacuated tube collector, sunlight passing through an outer glass tube heats the absorber tube contained within it. The absorber can either consist of copper (glass-metal) or specially-coated glass tubing (glass-glass). The glass-metal evacuated tubes are typically sealed at the manifold end, and the absorber is actually sealed in the vacuum, thus the fact that the absorber and heat pipe are dissimilar metals creates no corrosion problems. The better quality systems use foam insulation in the manifold. low iron glass is used in the higher quality evacuated tubes manufacture.

Lower quality evacuated tube systems use the glass coated absorber. Due to the extreme temperature difference of the glass under stagnation temperatures, the glass sometimes shatters. The glass is a lower quality boron silicate material and the aluminum absorber and copper heat pipe are slid down inside the open top end of the tube. Moisture entering the manifold around the sheet metal casing is eventually absorbed by the glass fibre insulation and then finds its way down into the tubes. This leads to corrosion at the absorber/heat pipe interface area, also freeze ruptures of the tube itself if the tube fills sufficiently with water.

Two types of tube collectors are distinguished by their heat transfer method: the simplest pumps a heat transfer fluid (water or antifreeze) through a U-shaped copper tube placed in each of the glass collector tubes. The second type uses a sealed heat pipe that contains a liquid that vapourises as it is heated. The vapour rises to a heat-transfer bulb that is positioned outside the collector tube in a pipe through which a second heat transfer liquid (the water or antifreeze) is pumped. For both types, the heated liquid then circulates through a heat exchanger and gives off its heat to water that is stored in a storage tank (which itself may be kept warm partially by sunlight). Evacuated tube collectors heat to higher temperatures, with some models providing considerably more solar yield per square metre than flat panels. However, they are more expensive and fragile than flat panels. The high stagnation temperatures can cause antifreeze to break down, so careful consideration must be used if selecting this type of system in temperate climates.

For a given absorber area, evacuated tubes can maintain their efficiency over a wide range of ambient temperatures and heating requirements. The absorber area only occupied about 50% of the collector panel on early designs, however this has changed as the technology has advanced to maximize the absorption area. In extremely hot climates, flat-plate collectors will generally be a more cost-effective solution than evacuated tubes. When employed in arrays of 20 to 30 or more, the efficient but costly evacuated tube collectors have net benefit in winter and also give real advantage in the summer months. They are well suited to extremely cold ambient temperatures and work well in situations of consistently low-light. They are also used in industrial applications, where high water temperatures or steam need to be generated. Properly designed evacuated tubes have a life expectancy of over 25 years which greatly adds to their value.

Energy Independence Day – Stop burning things up.

Community Energy Systems’ mission is to educate the public regarding energy conservation, energy efficiency, and the prudent and fair operation of utility companies. We believe that mission requires both intellectual and practical applications.

Energy Independence
Every July 4rth it is long over due that the people of Illinois declare their Energy Independence from the utility companies that prey on them and from the green house gases they emit.Everyday the Earth is bombarded by in excess of 27 gigawatts of power by the sun. This is after the Earth captures enough to grow all of the food to feed everyone on the planet. This is after the earth captures enough to warm the oceans. Yet the 27 gigawatts that we allow to be reflected away everyday is 7 gigawatts more than we humans consume in a single day. Instead the utility companies burn coal more desperately everyday.Everyday the Earth is orbited by the moon, which generates untold gigawatts of tidal power. These sources are so powerful that the first attempts to harness them in the Hudson River crumpled the turbines steel fins like so many sheets of tissue paper. This tidal power causes a drop in water levels in some extreme cases as much as 26 feet everyday. This generates more than enough power for a state like Illinois for an entire day. Instead the utility companies burn uranium more desperately everyday.

Everyday the Earth itself generates enough energy to power the state of Illinois. The Earth generates enough rain to power Illinois using smart hydroelectric systems. The Earth generates enough wind power to feed Illinois’ thirst for electricity everyday. Indeed when harvested properly the Earth generates enough geothermal energy to power Illinois everyday. And yet everyday the utility companies burn natural gas more desperately. So desperately that they are proposing huge Liquid Natural Gas ports up and down our coasts which will put peoples lives in jeopardy.

It is time for Illinois to stand up for its Energy Independence Day. Dig and Burn is no longer an earth acceptable way to generate energy. Burning the planet up is not the answer for Illinois’ future.

Windows Are For Losers – If you want to see the outdoors go outside

OKOKOK so that may seem a little extreme. Rammed Earth houses commonly have glass faces facing south. The owners still have to curtain them for half of the year. Light tunnels are a way to bring sunlight into the house and direct it to any task, with much less resulting heat gain.

More Efficient, Lower

Impact Solar Panels Developed

Evergreen Solar Announces

Improved Solar Technology

Massachusetts-based Evergreen Solar has announced a new line of high efficiency solar panels this month.

Called the ES-A Series, the 200, 205 and 210 W solar panels are made with Evergreen’s proprietary “String Ribbon” technology. Inside the company’s custom furnaces, a set of special parallel strings are pulled through a molten pool of silicon. A thin “ribbon” forms between strings as the silicon cools. The ribbon is then cut into wafers, which are fashioned into solar cells.

According to Evergreen, the carbon footprint of these new panels is up to 50% smaller than those of competitors, and they have a quicker energy payback — reportedly as fast as 12 months for installed panels. This last point is particularly exciting, since the amount of energy required to make solar panels has long been a bone of contention among critics of the technology.

Back in the late 90s, energy paybacks for solar panels were as high as seven years. Today, they are often reported as “1-5 years.”

Evergreen says it will begin production of its new panels by July. They will be built in its new manufacturing plant in Devens, Massachusetts, where the workforce has reportedly swelled from 300 to 1,000.

The company says its final products will include longer cables for easier installation, new clickable connectors and a new low voltage configuration for greater flexibility.
