It would not be surprising if you had never seen a Blue Cart before, as only small portion of the city has them currently. They look just like the familiar black trash cans that are lined up and down every Chicago alley, but instead they are blue. The Blue Carts by all reports are a resounding success, reducing the amount of waste by over 16% in the wards where they are available (so far in 2008, and the numbers keep going up), that's more than twice the effectiveness of the blue bag program's 8% (from the Chicago Tribune's 2005 estimate) .
Sadly many communities will have to wait for years for the Blue Carts to appear, there is a map detailing when a few select neighborhoods will be receiving the blue carts, but a more speedy and complete roll-out of the carts is non-existent because of mayor Daley blaming budget shortfalls. It seems a bit short-sighted to not fund a project that can actually make money for the city as the prices of all recycled commodities go up and up.. a call to the department of Streets and Sanitation or the Mayor's Office asking them to put their money where their mouth is may help to spur things along.
The Blue Carts will only serve smaller residential properties (homes and apartments with 4 or fewer units) known as low-density properties. Low-density residential properties create one-quarter of the waste the city disposes of, while the other three quarters of the city’s trash is generated by large residential buildings, offices, stores, restaurants, and other nonindustrial businesses, none of which are served by city garbage crews.
High-rise dwellers or inhabitants in buildings with more than five units should know that city laws require that you must have a recycling program available to you. Please ask your trash carrier or condo board / association about compliance with the "Chicago High Density Residential and Commercial Source Reduction Ordinance" more commonly known as the Burke-Hansen ordinance. Keep in mind that while these programs might cost more money, with proof of a recycling program multi-unit buildings can receive a 75$ rebate per housing unit to recoup the property tax money the city collects for trash removal. Don't fall for the blue-bag trap again if your building's trash carrier says that is how it separates recyclables, insist that your carrier show reports of how much of the trash they collect is recycled, and contact your alderman to ask for assistance. The Chicago Reader has a great article on a high rise success story that actually decreased waste removal costs.
For those without blue carts or multi-unit recycling initiatives, there is another option: the recycling drop-off centers scattered through the city. These are far from optimal since they force users to store their recyclables, then drive them to the big blue dumpster.. consuming precious space, gas, and time. But if you have a bit of extra room at home, you can fill your car for a trip to a drop off center.
So until our local government steps in and solves all of our recycling problems, you as an individual can indeed make a difference, immediately! In addition to City programs, other
fantastic local resources are available, like the Chicago Recycling Coalition's website which offers easy access to a wealth of recycling information; or the Chicago Resource Center, where business can call for a pickup of items usually destined to the trash, which are then reused or stored and offered for use to teachers and other community programs at liquidation prices.
Stay tuned for future postings on how to cut trash collectors completely out of the equation for yard waste and other organic matter, by composting!

There is a bigger problem at hand than high utility bills: on the hottest days of summer, electric system usage during peak hours can result in an overloaded generation system or delivery grid... and that can mean brownouts- or even worse- blackouts.
Another interesting challenge that hot weather and its close cousin water shortage poses is that nuclear power plants actually have to reduce their power output during heat waves, or shutdown completely because of lack of cool water. Nuclear reactors use fission to heat water into steam, turning turbines that generate electricity, and then cool that steam back into water and feed it back through the core, repeating the process. Without lots and LOTS of water this system doesn't work. One reactor pumps 1 BILLION gallons a day of water through its cooling systems and back into waterways, other reactors (the type with the distinctive cooling stacks we all know from the Simpsons) can evaporate 17 million gallons a day into the air! Without adequate water supplies, reactors must drop energy output or shutdown.
Illinois is a large user of nuclear power, but is at a lower risk of being affected by this type of issue than the southern states because our rivers and lakes are cooler, but don't think that when any reactor in the country shuts down unexpectedly that everyone's electricity rates won't go up!
There are ways to avoid the cooling crunch: The easiest way to combat an overloaded grid, while still enjoying the same habits and lifestyle, is an air conditioner cycling system like ComEd's Nature First program. Depending on the program you select, ComEd will credit your bill either $5 or $10 dollars a month for 4 months (from the beginning of June, till the end of September) if you let them attach a small radio controlled switch to your central air conditioning unit's outside compressor. If and when demand cannot be met, or the grid is approaching a danger threshold, ComEd sends a radio signal that will turn off the AC compressor, but still allow your homes air circulation fans to run. The $5 a month credit will allow ComEd to cycle your compressor on and off every 15 minutes, while the $10 credit will allow for one continuous 3 hour block of time where the compressor is disabled. This program is only active during weekdays, and having been a user of the system for some years myself, I have never experienced more than 4 activations of the service in one year, and they tend to happen in the mid afternoon, when I'm not home anyways. The fact that most AC systems are oversized for the house they cool is another story, but running your air on and off for 5 minutes at a time is really horrible for efficiency!
For the more flexible users of electricity, Illinois along with ComEd have pioneered a new and innovative program for residential users known as 'Residential Real Time Pricing' or RRTP. Under this program, you pay the hourly market rate for electricity, rather than the 'averaged' market rate. You can get a hint of the difference in how these these rates fluctuate by looking at ComEd's current residential 'Basic Electric Service' (or BES) rate sheet, where 'general lighting' costs 7.212 cents/kWh while 'dusk to dawn lighting' costs only 2.760 cents/kWh.
If you are thinking "so what, that's not that much difference", consider that I have saved more than $800 over the 5 years I have been on a Real-Time Pricing program, by simply thinking about how and when I use electricity, and making some small adjustments to my life!
I was an early user of this program when it was still administered by the community energy cooperative, and it was known as the Energy Smart Pricing Plan, or ESPP. ESPP was wonderful because you knew what electricity rates were going to be for the day the evening before, and could plan your activities accordingly if rates were to be high. ComEd's current RRTP program uses a rate known as BES-H (residential-hourly), this pricing plan gives you an estimate of tomorrows prices, but you will only know what you are paying for that power as they day progresses; and sometimes what you end up paying is way off the estimated cost.. These prices change every 5 minutes, so good luck keeping up with them! Luckily, there is a service available for ComEd customers on the RRTP program, called Load Guard (open PDF). Load Guard lets you use the same AC compressor switch installed when enrolled in Nature First, and takes the concept a step further: if your electricity rates exceed a preset threshold of either 10 or 14 cents/kWh, your AC compressor is cycled on and off just like in the Nature First $5/ month program.
There are many ways to beat the heat, of course turning off the AC and sipping some iced tea in frot of a fan is a great way to lower your electricity consumption, but few homeowners are willing to give up the luxury of Air Conditioning. So if you have central AC and love it, why not save 20$ or 40$ a year by signing up for Nature First

I was informed by the city that the barrels for sale at the environmental resource event are no longer the blue eye-sores that were for sale previously:
"The rain barrels are available in black and terra cotta (brick red) this year; however, the design is similar to last year in that they are formally food processing barrels ranging from 55-60 gallons."
Rain Barrels are fantastic tools for anyone who has anything growing outdoors that needs watering. They not only help to reduce water consumption, but also reduce the runoff that occurs when Chicago's shared sewer system fills up or is stressed by rains.
I have used a water barrel connected to a drip irrigation system and a timer to automatically water my vegetables as needed on my deck-top garden, and have had fantastic results!
Rain barrels can usually run upwards of 100$, but the city of Chicago is again offering a subsidized purchase program this year, allowing any Chicagoan one barrel per household at the cost of 40$. The barrel looks about like the one on the picture below:
Questions about the city's current rain barrel programs can be answered by calling the Chicago Department of the Environment at 312-743-9283 or by emailing firstname.lastname@example.org
The current rain barrel event details are as follows:
Saturday June 21st
US Cellular field
333W 35th Street
40$ for one barrel, payable by check or money order only- checks need the current city address on them, and only one rain barrel is available per household
30$ for Earth Machine Compost Bins, which include a 10 year warranty for missing / broken parts (you only pay shipping) from the manufacturer
Please see this post for more information on this Environmental Resource Event!
If you live in a building with no area to let overflow from your water barrel soak into the ground, I recommend using a downspout diverter. I have used the Garden Water saver, and though it once in a while it will clog (and no longer fill the rain barrel, but will still drain downspout water) it works pretty well.

Radon gas is an odorless, invisible radioactive gas that is produced by the natural process of radioactive elements in the ground breaking down.
Here is some interesting information about radon gas:
- Radon is the leading cause of lung cancer among non-smokers.
- Radon is the second leading cause of lung cancer in America and claims about 20,000 lives annually.
- Radon is one of the heaviest gasses present under normal room temperature conditions.
- Radon's most stable isotope, radon-222, has a half-life of about 3.8 days. It decays into polonium-218 through alpha decay.
- Radon can be carried into your home through natural gas (think kitchen: range, oven).
Most folks in Northern Illinois are not aware that they live in a medium to high risk area for radon exposure. See the image below for your area's risk level, (taken from the EPA's radon zonemap Red = "action" levels over 4 pCi/L (pico curies per liter); Orange = moderate risk at 2-4pCi/L; Yellow = low risk at under 2 pCi/L).
The good news is that with some minimal effort, unsafe levels of radon can be detected; and if found, your home can be made safe from radon with minimal investment.
It is important to test your home for radon, as levels vary greatly from home to home, and from season to season; even neighbors can have very different levels of radon. Generally speaking, the highest radon levels will occur when the ground is warm, and the lowest levels when it is frozen. Radon levels can even vary large amounts from week to week, so radon tests that take a longer time to complete (alpha-track counters that take one or more months) generally yield more accurate results.
The Illinois Emergency Management Agency (IEMA) offers Illinois residences free radon test kits. These tests consist of a sponge-like carbon 'collector' that you unwrap and place in a test area for three to 7 days, then wrap back up and send in to a lab for analysis. < UPDATE: The free test kit program was stopped, because two-thirds of the test kits sent out were never used.. A listing of test kits is
For those not living in Illinois these tests may be available free or at a discount from your state or local public health & safety agencies, at your local hardware store, or can be purchased online:
For continuous monitoring of radon levels, electronic alpha-track counters that display the radon levels and sound and alarm when high levels are detected are available, but more expensive at over 100$.
Anyone who has sealed air leaks in their home should also be sure to re-test for radon, as reduced air flow can result in increased radon concentrations.
New homes should be built with 'passive' sub-slab depressurization radon mitigation systems, these systems help to vent radon gas from under the home using natural air movement, and generally cost $400-1000 to install during construction. Another advantage to these systems is if radon levels are found to be elevated in the home after construction is completed, they can be easily converted into an 'active' mitigation system by adding a radon mitigation fan to help move the radon gasses away from the home foundation. Note : a licensed radon mitigation specialist must install the fan to meet state requirements.
If you find you have high radon levels in your existing home, some steps can be taken to try and reduce the amount of air that contains radon from coming into your home. The primary way radon enters the home is through ground air infiltration. Putting an air-tight cover over your sump pit and sealing cracks along the floor of your foundation can go a long way to reduce radon levels. Making sure your stove vent runs to the outdoors and being sure to run the vent while cooking can also help to reduce radon levels and other indoor air pollutants.
Adding an active mitigation system to an existing house is usually more expensive and less effective than adding the passive system during construction, and can range in cost from $800-$3000.
Be aware- As of January 1st, 2008; if you have a Radon test performed in your home, you must disclose the results to any future potential buyer, because of a new state Public Act 095-0210 "Illinois Radon Awareness Act". Even if you don't test, you must include a signed statement saying that you don't know of any radon information, and include the pamphlet "Radon Testing Guidelines for Real Estate Transactions".
