CWLP Offers 15,000 $$$ Solar Rebate – Home owners should move fast

I know I said I was done with the residential housing market last Friday. I was talking to Bob Croteau about which side of the insulation the vapor barrier should be on if you are insulating the upper portion of your  basement and he mentioned this in passing. By the way the answer is the vapor barrier should be on the basement side of the insulation and he suggested  only insulating 4 feet of the basement from the top of the basement wall down. After that you are pretty much wasting your time. On to the solar rebate. The reason I said to hurry and get it if you were thinking about solar it is because it is on a first come first serve basis.

SOLAR REWARDS Rebate

CWLP’s SOLAR REWARDS program offers rebates of up to $15,000 per household or business to CWLP electric customers who install solar electric—also known as photovoltaic (PV)—systems at their residential or commercial facilities. To qualify for participation in the program, customers must meet all eligibility criteria, including being pre-approved prior to purchasing any equipment or starting any work.

The SOLAR REWARDS rebate program is being offered on a first-come/first-served basis until funds budgeted for the program are exhausted. The rebate is calculated at $1,500 per kilowatt (kW) of system capacity. Qualifying systems can range from a minimum of 0.5 kW to a maximum of 25 kW. Rebates will be provided in the form of a CWLP bill credit. For rebates exceeding $1,000, applicants may request their rebate payment in the form of a check, but must provide CWLP with their social security number or FEIN number. Customers have 90 days from the date of their pre-approved application to complete their PV system installation and submit their post-installation documentation to CWLP. Failing to either meet this deadline or receive a deadline extension from CWLP will result in the loss of rebate eligibility.

To apply to participate in the SOLAR REWARDS Rebate Program, use the Pre-Approval Application in the online SOLAR REWARDS Application Packet. To request a hard copy of the Packet, contact the CWLP Energy Services Office by phone at 789-2070 or by email.

Photovoltaic systems convert energy from the sun into electricity using panels that are installed to take maximum benefit of available sunlight. Some systems are even designed to allow the panels to “track” the sun throughout the day. The lifespan of a typical PV panel is approximately 25 years.

Using solar energy can help homeowners and businesses reduce consumption of fossil fuels and lower their monthly energy bills by reducing the amount of electricity purchased from CWLP. (View photos of a sampling of PV systems that have been installed in Springfield.)

Residential applicants can combine CWLP’s SOLAR REWARDS rebate with Federal tax credits or State of Illinois incentives to make solar a more affordable renewable resource option.

For more information about the SOLAR REWARDS Rebate Program or about photovoltaic systems, contact the CWLP Energy Services Office at 789-2070 or nrgxprts@cwlp.com.

While Consumer Reports does not like “on demand” water heaters, I do. Once you get used to them they are a blessing and if you have a large family the money you can save is amazing. But for me it is a mental thing. First in mind solar water heating should have been the way our society should have gone 100 or even 200 years ago. I mean it is there and we “throw it away”. But there is also something so bourgeoisie about heating up a bunch of water to sit in a tank wating for us to (what?) fain to use it. But if we don’t then a heater comes on and heats it up again. The whole mindset there is flawed.

http://www.tanklesswaterheaterguide.com/

Tankless Water Heaters heat water directly without the use of a storage tank. Therefore, they avoid the standby heat losses associated with storage water heaters. When a hot water tap is turned on, cold water travels through a pipe into the unit. In an electric Tankless Water Heater an electric element heats the water. In a gas-fired Tankless Water Heater a gas burner heats the water. As a result, Tankless Water Heaters deliver a constant supply of hot water. You don’t need to wait for a storage tank to fill up with enough hot water. Typically, Tankless Water Heaters provide hot water at a rate of 2 – 5 gallons (7.6 – 15.2 liters) per minute. Typically, gas-fired Tankless Water Heaters will produce higher flow rates than electric Tankless Water Heaters. Some smaller Tankless Water Heaters, however, cannot supply enough hot water for simultaneous, multiple uses in large households. For example, taking a shower and running the dishwasher at the same time can stretch a Tankless Water Heater to its limit. To overcome this problem, you can install a “whole house” type Tankless Water Heater or install two or more Tankless Water Heaters, connected in parallel for simultaneous demands of hot water. You can also install separate Tankless Water Heaters for appliances—such as a clothes washer or dishwater—that use a lot of hot water in your home.

Other applications for Tankless Water Heaters include the following:

  • Remote BBQ or outdoor sink
  • Poolhouse or pool shower
  • Remote bathrooms or hot tubs
  • To serve as a booster, eliminating long pipe runs, for solar water heating systems, dishwashers and sanitation.

Insulate Your Basement – Even in an already built home

Posted on by
2

Yes, you can get a backhoe and dig a trench around your house for relatively cheap but, it really is a waste of time. Parging the walls first pretty much means coating the walls to make sure moisture does not get behind the insulation that you are going to put up. I suggest using a modern basement epoxy of some sort and I recommend rigid insulation after you have done that. Rigid is easier to work with and you can make the whole project into an adhesive affair where you adhere the furring strips to the epoxied walls and then you adhere the foam board (or whatever) to the furring strips. Boom, you are done unless you need to paint them for someone else in the house that hates the color of the “naked” board. You know who I mean. Like the article says as far as the vapor barrier placement you have to call your local building code people cause I got no idea,

 

http://www.green-energy-efficient-homes.com/energy-efficient-basement.html

Exterior wall insulation inside the walls

Insulating outside your exterior walls is often too expensive or impractical in existing homes. You can insulate the inside of your basement walls but you may exacerbate the problems associated with moisture if you don’t do the job correctly.

Parging: If moisture is seeping into your walls, parge the masonry walls to seal any cracks and strengthen any weak or porous masonry. This will help prevent water from seeping in from outside.

Vapor barrier: Vapor barrier should be outside the insulation if you are in a hot climate and only cool your home; it should be on the inside if you are in a cold climate and are mainly heating your home. Consult your local city building permits department to find out what are the suggested or mandated insulation and vapor barrier configurations for energy efficient basements in your area.

Framing: If possible, leave a gap between your framing and the exterior walls, to prevent moisture from the masonry from causing wood rot in your framing. Use small spacers behind 2×3 studs, rather than 2×4 studs against the outside wall, and you’ll still have room to install the standard insulation for 2×4, 16-inch-stud construction.

Insulation: If there is any likelihood of moisture getting into your basement, use a rigid foam insulation rather than batt or other fiber-based insulation. Moisture seeping through exterior walls will dampen the insulation and reduce its R value significantly within a few years, so you’ll start with an energy efficient basement and in a few years be losing as much heat to outside as before the renovation. Moisture will not have much effect on the R value of foam insulation. Buy the highest R value insulation you can – you can get an R value of 6 per inch in some insulating foam sheets. If you want both insulation and waterproofing, you could consider having Icynene insulation applied to exterior walls after framing but before drywall is installed.

Other places you should insulate

A couple of other important things to consider about basement insulation:

  • In an older house, where a shower stall is already installed against an outside wall, check the insulation level behind the shower. A prior owner or contractor may have installed the shower without adequate insulation. If you are remodelling or can access the wall space behind it, inject foam insulation or otherwise upgrade the insulation. You’ll have more comfortable showers and you’ll cut down on overall heat loss.
  • Insulate the perimeter of your basement ceiling (an area called the ‘rim joists’), from the outside walls to about 16″ to 24″ from the outside walls, to prevent moisture from creeping in between the upstairs

People traditionally do not think of their car or other forms of personal transportation as part of their residential energy package but I think it only makes sense. In between gas and insurance along or electricity now, they can be some of the most expensive things in your life. And it is a big part of of your carbon footprint. This would sure make a differenced.

Fold-up car of the future unveiled at EU

January 24, 2012

A tiny revolutionary fold-up car designed in Spain’s Basque country as the answer to urban stress and pollution was unveiled Tuesday before hitting European cities in 2013.

A tiny revolutionary fold-up car designed in Spain’s Basque country as the answer to urban stress and pollution was unveiled Tuesday before hitting European cities in 2013.

The “Hiriko”, the Basque word for “urban”, is an electric two-seater with no doors whose motor is located in the wheels and which folds up like a child’s collapsible buggy, or stroller, for easy parking.

Dreamt up by Boston’s MIT-Media lab, the concept was developed by a consortium of seven small Basque firms under the name Hiriko Driving Mobility, with a prototype unveiled by European Commission president Jose Manuel Barroso.

Demonstrating for journalists, Barroso clambered in through the fold-up front windscreen of the 1.5-metre-long car.

“European ideas usually are developed in the United States. This time an American idea is being made in Europe,” consortium spokesman Gorka Espiau told AFP.

Why Conserve Energy – Save money and save the planet

Every once in awhile it does not hurt to remind people why we do this.

http://www.nasa.gov/topics/earth/features/2011-temps.html

NASA Finds 2011 Ninth-Warmest Year on Record
01.19.12

The global average surface temperature in 2011 was the ninth warmest since 1880, according to NASA scientists. The finding continues a trend in which nine of the 10 warmest years in the modern meteorological record have occurred since the year 2000.

NASA’s Goddard Institute for Space Studies (GISS) in New York, which monitors global surface temperatures on an ongoing basis, released an updated analysis that shows temperatures around the globe in 2011 compared to the average global temperature from the mid-20th century. The comparison shows how Earth continues to experience warmer temperatures than several decades ago. The average temperature around the globe in 2011 was 0.92 degrees F (0.51 C) warmer than the mid-20th century baseline.

We know the planet is absorbing more energy than it is emitting,” said GISS Director James E. Hansen. “So we are continuing to see a trend toward higher temperatures. Even with the cooling effects of a strong La Niña influence and low solar activity for the past several years, 2011 was one of the 10 warmest years on record.”

The difference between 2011 and the warmest year in the GISS record (2010) is 0.22 degrees F (0.12 C). This underscores the emphasis scientists put on the long-term trend of global temperature rise. Because of the large natural variability of climate, scientists do not expect temperatures to rise consistently year after year. However, they do expect a continuing temperature rise over decades.

The first 11 years of the 21st century experienced notably higher temperatures compared to the middle and late 20th century, Hansen said. The only year from the 20th century in the top 10 warmest years on record is 1998.

These guys have a pretty good rap though and a lot of experience.

http://www.radiantsolar.com/why_solar.php

This is why Solar Heating should be a part of your building project

An underfloor heating system from Radiantec Company is the most comfortable and efficient choice you can make, no matter what fuel you choose… but when you select solar as the energy source, you can really feel good about your energy decision.

Here are the benefits of Solar Heating:

  • Solar heat is environmentally friendly. Solar heat does not pollute or produce greenhouse gases. It helps conserve the earth’s energy resources for our children and grandchildren.
  • Solar is as pure, clean and safe as you can get. It is the best choice for people with allergy problems and chemical sensitivities. There will be no tanks of highly flammable materials in your house. It will be free of fuel odors and there will be lower electromagnetic fields.
  • Solar heating is stable in price. Once you have bought it, you are protected from inflation and the political surprises that come with other fuels.
  • Solar heating is a wise investment. The yield is comparable to a good stock. One nice thing is that the yield from your solar investment is tax free and that the yield goes up in value at the rate of inflation. Imagine what that could be in 20 years!
  • Solar heat makes your home something special. People with solar heated homes are intelligent, self-confident, socially aware and environmentally responsible.

Saving energy means saving money as well as saving the mekong

In this very fast-changing region, few countries are changing faster than Laos. With economic growth of around 8%, the country is awakening and Vientiane is bustling with new developments, new trucks, and an even brighter outlook. Laos is finally catching up with its neighbours, and though this will take time, the pace and direction is undeniably clear and strong.

However, beneath this strong economic growth is a challenging story. Numerous rivers are being dammed for power production as Laos pursues its vision to become the “Battery of Asia”, and about 90% of this power is for export to Thailand and Vietnam.

Obviously Laos is not the only country growing in this region, and the demand for electricity is understandably strong. But the “Land of a Million Elephants” is becoming the “Land of 50 Dams” and that affects us all. This is because the dams are on the tributaries and water catchments of the great Mekong River. Indeed, according to the Mekong River Commission, nearly one-third of Thailand is actually in the Mekong River basin. The current dams in the Mekong basin produce around 1,600 megawatts yet the potential is estimated at 30,000 MW. And with around 60 million people depending on the Mekong for food, water, and transport the number of people directly linked to the river is huge _ approximately the same as the population of Thailand itself. And these dams will have an uncertain impact on this important inland fishery.

Electricity is vital for economic growth and it is vitally important for countries to have very reliable sources of high-quality power to drive their economies forward. But not all electricity has to be used in an inefficient way, and by getting serious about energy efficiency, the demand growth can be reduced. And this will mean that fewer dams are needed on the precious Mekong and its basin. Countries such as Thailand and Vietnam getting more strict about energy efficiency will better preserve the region’s key river.

Dual Air Conditioning – What an energy saver

Posted on by

Not much to say about this. Just a pretty nifty idea. I am going to put up a couple of the central paragraphs.

http://www.sciencedaily.com/releases/2010/06/100621071943.htm

New Air Conditioning System Has Potential to Slash Energy Usage by Up to 90 Percent

ScienceDaily (June 21, 2010) — Ah, the cool, refreshing feel of air conditioning on a sweltering summer day.

dot dot dot (as they say)

DEVap: Liquid Desiccants, Permeable Membranes

The DEVap solves that problem. It relies on the desiccants’ capacity to create dry air using heat and evaporative coolers’ capacity to take dry air and make cold air.

“By no means is the concept novel, the idea of combining the two,” Kozubal said. “But no one has been able to come up with a practical and cost-effective way to do it.”

HVAC engineers have known for decades the value of desiccants to air conditioning. In fact, one of the pioneers of early A/C, Willis Haviland Carrier, knew of its potential, but opted to go the refrigeration route.

Most people know of desiccants as the pebble-sized handfuls that come with new shoes to keep them dry.

The kind NREL uses are syrupy liquids — highly concentrated aqueous salt solutions of lithium chloride or calcium chloride. They have a high affinity for water vapor, and can thus create very dry air.

Because of the complexity of desiccant cooling systems, they have traditionally only been used in industrial drying processes. Inventing a device simple enough for easy installation and maintenance is what has impaired desiccant cooling from entering into commercial and residential cooling markets.

To solve that problem, the NREL device uses thin membranes that simplify the process of integrating air flow, desiccants, and evaporative cooling. These result in an air conditioning system that provides superior comfort and humidity control.

The membranes in the DEVap A/C are hydrophobic, which means water tends to bead up rather than soak through the membranes. Imagine rain falling on a freshly waxed car. That property allows the membranes to control the liquid flows within the cooling core. “It’s that property that keeps the water and the desiccant separated from the air stream,” Kozubal said.

“We bring the water and liquid desiccant into DEVap’s heat-mass exchanger core,” Kozubal said. “The desiccant and evaporative cooling effect work together to create cold-dry air.”

The air is cooled and dried from a hot-humid condition to a cold and dry condition all in one step. This all happens in a fraction of a second as air flows through the DEVap air conditioner. The result is an air conditioner that controls both thermal and humidity loads.

DEVap helps the environment in many ways. DEVap uses 50 percent to 90 percent less energy than top-of-the-line refrigeration-based air conditioning.

Improve The Heating In Your Home – Condensing gas furnaces

Posted on by
Reply

We have been meditating on improving your residences energy efficiency, inlcuding new windows and new roofs. If you live in a colder environment one of the most important things to do is improve your heat source. We will talk about solar, electric, and geothermal heat sources in the coming days. First up is natural gas. I wish there was a date on this particular piece. Maybe if the writer of this sees the linkage he could supply the date. I am not sure this is the latest in natural gas technology, but considering the ages of much of the heating systems out there this would be a huge step up.

http://www.handyamerican.com/articles.asp?id=45-New-Condensing-Gas-Furnaces

New Condensing Gas Furnaces

The invention of the condensing gas furnace couldn’t have come at a better time for American homeowners, gas users who have been watching the natural gas prices rise to heights that were once thought impossible. And any relief in the prices will only be short-lived because of the volatility of the fossil-fuel market.

In the colder areas of the country gas and oil are staples to provide heat for the home. In an effort to get relief from the fossil fuel crunch many homeowners are looking to various alternative methods like off-peak electric and solar hot water heat. However, these systems have very expensive start-up costs and, even with state and federal rebates, the costs can be double that of a gas-run furnace. The idea of a condensing gas furnace is to wring every last BTU of heat out of a unit of burnt gas.

Natural Gas Prices Are Sinking Gas Furnaces

Older gas furnaces waste a lot of energy. They are basically a metal box with a burner and blower apparatus The thermostat tells the furnace control that the house is cooling off and the burner is ignited. When the temperature inside the furnace header pipe, or plenum, reaches a certain point, the blower fan starts up and hot air is blown through the air ducts and into the rooms of the home.

The system works seems to work very efficiently but in actuality the reverse is true. Studies have shown that most of the gas furnaces over a ten years-old can only convert 55% of the natural gas burned into heat comfort for the home. The standard for measuring this efficiency is the AFUE, or Annual Fuel Utilization Efficiency.

Condensing Gas Furnaces Are Breaking the Ice

As the natural gas prices go up it doesn’t mean that gas cannot be an economical way to heat the home. New technologies in all parts of the gas furnace have upped the efficiency of the units to an AFUE mark of 97 as compared to 55 for the old furnaces. These modern inventions include dual heat exchanging systems, more efficient gas valves, redesigned fan blowers and electronic motor technology. The new condensing gas furnaces combine all these new innovations into one energy-efficient package.

The Parts of the Condensing Gas Furnace

A traditional gas furnace heats a home by the combustion of the gas under a heat exchanging plate. The more heat that can be transferred to the heat exchanger is less heat that is allowed to go up the chimney. The ability to squeeze 25% to 45% more heat from a unit of gas than the old-style furnaces makes the condensing gas furnace a more energy-efficient source of heat production.
