COOKING

Range Tops

To cook efficiently, heat must be trans-ferred from the electric cooking element to the food with minimum loss to the surroundings. To help do this, select pots and pans with absolutely flat bottoms. Spherical bottoms leave an air gap that provides a ready escape route for heat.

Expand your family’s menus to include stews and other single-dish meals that can be prepared in a slow cooker. Such meals require far less energy than those calling for the simultaneous use of the oven plus two or three surface units.

Develop the habit of “lids-on” cooking. Tightly fitted lids help keep heat within pots and pans, permitting the use of lower temperature settings and shorter cooking times.

Reflector pans beneath stovetop-heating elements should be kept bright and clean. Shiny pans help focus heat rays on utensil bottoms; dull or soiled pans absorb heat wastefully.

Begin cooking on highest heat until liquid begins to boil. Then lower the heat control setting and allow food to simmer until fully cooked.

Ovens

Use your microwave oven whenever possible. Microwave ovens draw less than half the power of their conventional counterparts and cook for a much shorter period of time. For example, an item that needs to be cooked in a full-sized oven at 3500 F for one hour will take only 15 minutes to cook in a microwave on the “high” setting.

Rather than using the oven for preparing small quantities of food, consider cooking in small portable electric appliances such as a frying pan, grill, or toaster oven. On average, these use only about one-third of the electric power of an oven broiler.

When operating an electric oven, at-tempt to cook as much of the meal in it at one time as possible. Foods with different cooking temperatures can often be cooked simultaneously at one temperature—variations of 25 degrees in either direction still produce good results and save energy.

When preheating an oven for baking, time the preheat period carefully. Five to eight minutes should be sufficient. There is no need to preheat for broiling or roasting.

Rearrange oven shelves before turning the oven on. To do this after the oven has preheated not only allows wasteful escape of heat but poses a burn hazard as well.

When roasting or baking, avoid making frequent progress checks that entail opening the oven door. Each time the door is opened, a considerable portion of the oven’s heat escapes.

Energy You’ll Save: Using a microwave oven can reduce your energy used for cooking by more than 50 percent.

Activate the self-cleaning cycle on an electric oven only for major cleaning jobs. Wipe up minor spills and splatters with a damp cloth. When self-cleaning is neces-sary, start the cycle right after cooking, while the oven is still hot, or wait until late evening hours when use of electricity is lowest.

Never use an open electric oven as a room heater or as a source of warm air for drying rain-dampened outerwear. If the kitchen is furnished with the type of refrigerator or freezer that exhausts warm air through a front floor-level grille, damp shoes can be dried quite nicely and at no extra energy cost by placing them on the floor near the grille.

FOOD REFRIGERATION

Select refrigerator and freezer sizes that are just large enough for your family’s needs. Operating energy is proportional to cubic feet of refrigerated space, regardless of whether all of the space is utilized.

Consider replacing your refrigerator or freezer BEFORE it breaks down. Look for the ENERGY STAR® label when shopping for refrigerators or freezers. On average, ENERGY STAR® refrigerators use at least 12 percent less energy. New federal energy efficiency standards for refrigerators took effect on July 1, 2001.

NEVER put a second refrigerator in the garage. In the winter months, frozen foods may melt (as the temperature sensor in the refrigerator will not activate the compressor if the temperature in the garage is 420 F or lower). In the summer months, the temperature in the garage can easily exceed 1000 F, and the refrigerator has to work extra hard to keep food cold. If you need a second unit, place it in your basement.

On older units, vacuum clean the con-denser coils of refrigerators and freezers (in the back or at the bottom of cabinets) every three months or so. Dust-covered coils impair the efficiency of compressor operation and increase energy usage.

Door gaskets on refrigerators and freezers should seal tightly against the frames to prevent infiltration of warm air. To check the condition of the gasket, place a dollar bill against the frame and close the door. If the bill can be pulled out with a very gentle tug or, worse still, simply drops out on its own, the door requires adjustment, or the gasket needs replacing.

Some older refrigerators are furnished with a power-saver switch. A heating ele-ment provides a small amount of heat that prevents moisture condensation around the edges of the door. Try turning the switch off; condensation, if any, may be slight and unobjectionable. If this is the case, save energy by keeping the switch off.

When buying a new refrigerator, look for new energy-saving features such as improved insulation materials. These features can save as much as 10 percent in annual consumption of electricity.

Do not place uncovered liquids in refrigerators. In addition to absorbing undesirable flavors, the liquids give off vapors that add to the compressor work-load.

Allow hot foods or liquids to cool off before placing them in the refrigerator. The cooling-off period should not hurt the taste of the food and will reduce the load on the refrigerator. Discard any un-cooked food that has remained at room temperature for more than two hours.

Plan ahead and remove all ingredients for each meal at one time. Each time the door of a refrigerator or freezer is opened, its compressor has to run a bit longer to replace the cold air that spills out.

Chest-type freezers are less likely to lose cold air when doors are opened than upright freezers.

For the same storage capacity, chest-type freezers use anywhere from 11 to 27 percent less energy than upright freezers.

Compiled by the Edison Electric Institute 2008© Washington, D. C. www.eei.org

HEATING

If you are buying a new heating system, consider a high-efficiency electric air source or ground source heat pump. The energy efficiency is rated according to a federal standard called the Heating Seasonal Performance Factor, or HSPF. Heat pumps with an HSPF of 10 are al-most three times more efficient than the most efficient gas furnaces. In January 2006, the new minimum efficiency for air source heat pumps rose to 7.7 HSPF, while efficiency levels for furnaces and boilers have not increased since 1992.

Ground source heat pumps, or GeoEx-change units, use the Earth as a heat source in the winter and as a heat sink in the summer. Ground source heat pumps are rated in terms of Coefficient of Performance (COP) for the winter. The higher the COP, the higher the efficiency. Where gas furnaces have COP values in the 0.78 to 0.94 range, ground source heat pumps have COP values in the 3.0 to 5.0 range.

In the heating season, water vapors from bathing and cooking are beneficial because they help humidify the home. So, use kitchen and bath exhaust fans sparingly in the winter to keep as much heat as possible inside your house.

Locate the heating thermostat on an inside wall away from windows and doors. Cold drafts will cause the thermostat to keep the system running even when the rest of the house is warm enough.

Set the heating thermostat as low as comfort permits. For instance, each degree above 680 F can add 3 percent to the amount of energy needed for heating. If you have a heat pump, make sure that the thermostat is designed to operate the heat pump efficiently when raising the temperature after it has been lowered.

When entertaining a large group of people during the heating season, lower the thermostat a degree or two before the guests arrive. Otherwise, since people generate heat, the space may become wastefully overheated.

Lubricate pump and blower bearings regularly in accordance with manufactur-ers’ recommendations to limit the amount of energy lost to friction and to extend equipment life as well.

Close heating vents and radiator valves in unused rooms. Make sure that drapes, plants, or furniture do not block registers for supply or return air.

COOLING

Air conditioners vary considerably in efficiency and in the amount of energy used. Therefore, select equipment based on its federal energy efficiency rating. For window units, this rating is the Energy Efficiency Ratio, or EER. New standards for room air conditioners went into effect on October 1, 2000. For many types of room air conditioners, the minimum EER is 9.0 or 9.7. As a general rule, an EER of 11 or more is excellent.

Central air-conditioner units are rated on their Seasonal Energy Efficiency Ratio, or SEER. A rating of 14 SEER is excellent, and the minimum cooling efficiency for air conditioners and heat pumps is 13 SEER. An ENERGY STAR® unit will have a SEER level of 14 and an EER of 11.5.

Seek professional help when determining the size of cooling equipment needed. Oversized units should be avoided—not only because they draw more energy than is necessary, but also because they cannot dehumidify properly.

Locate the compressor units of central air-conditioning and heat pump systems in an outside area that is shaded by the house or by trees and plants. Units should be kept clean and free of any plant or tree overgrowth.

Direct sunlight falling on a window air-conditioning unit increases its workload. When a choice is possible, locate such units on the north or shady side of the house.

Set the cooling thermostat as high as comfort will permit. The higher the set-ting, the more energy you save.

Attics must be ventilated to relieve heat buildup caused by the sun. When planning a new home, install vents of proper size and location to ensure attic ventilation by natural airflow. For existing homes, determine whether attic ventilation is adequate and, if necessary, improve airflow by adding or enlarging vents.

Choose light-colored roof shingles for your house to reflect more of the sun’s heat. The darker the shingles, the more heat will be absorbed during the summer season.

Open windows during the moderate weather of spring and fall to admit outside air for cooling instead of operating air-conditioning equipment.

Close cooling vents and turn off window air conditioners in unused rooms. Keep doors to unused rooms closed.

Draw blinds, shades, or drapes to block the sunlight during the hottest part of the day, especially on south- and west-facing windows.

In the cooling season, run kitchen and bath exhaust fans only long enough to rid the house of unwanted water vapor and odors.

Don’t position heat-producing devices such as lamps and TV sets beneath a wall-mounted thermostat for a central cooling system. Heat rising from the equipment could cause the thermostat to read a temperature higher than the true room temperature and lead to over-cooling.

AIR INFILTRATION

Find the obvious places where air can sneak into your home, then make repairs to plug the leaks by caulking, weather-stripping, and using plastic covers.

Some of the major air leakage areas for the average home are: air ducts; window sashes and frames; fireplaces; door sashes and frames; plumbing utilities and wall penetrations; furnace flues; attic entrances; wall outlets; and recessed light fixtures.

Keep the overhead door of an attached garage closed to block cold winds from infiltrating the connecting door between the house and garage.

Fireplaces should have tightly fitting dampers that can be closed when the fireplace is not in use. Open dampers allow the natural draft of chimneys to pull warm air out in winter and cool air out in summer.

Close fireplace doors when not in use to reduce air infiltration and heat loss.

INSULATION

The single most important step in resi-dential energy conservation is the installation of thermal insulation. Check current insulation levels, and properly insulate a new or existing home according to the U.S. Department of En-ergy’s specifications for your geographic area. Insulate ceilings, walls, and floors over unconditioned crawl spaces.

Double-glazed windows (two panes of glass separated by a sealed air space) cut heat transfer by 40 to 50 percent. In extremely cold regions, triple glazing could be economically justified.

Single-glazed windows should have storm windows. A wood or metal frame storm window provides a second thickness of glass and a layer of still air that reduces heat transmission markedly.

Install storm doors at all entrances of the house. A storm door helps save energy because it reduces the mass of air infiltration that occurs when the prime door is opened and also reduces the amount of heat transfer through the prime door when it is closed.

Weatherstrip and caulk around all en-trance doors and windows to limit air leaks that could account for 15 to 30 percent of heating and cooling energy requirements.

In the winter, the air is normally dry inside your house. This is a disadvantage because, to be comfortable in dry air, people typically require a higher temperature than they would in a humid environment. Therefore, efficient humidifiers are a good investment for energy conservation.

Oh, how we love to drive!

Sunday, October 18th, 2009

As Cleveland and other cities were really in their hayday, people lived in cities. Tight urban communities with dense neighborhoods. The city was served by trolley, train, and rail. It was simply the way to get around. Every neighborhood had access to all the things that you might need. You had a local grocer or two. You bought the fuel for your heat within walking distance. Luxury goods were a little less common and you might have to make that special trip to buy new fabric or a piece of furniture. Many relied on catalog or other delivery services to get the non essential goods that they needed. Things changed with the introduction of the automobile. we could drive to get the goods we needed, no need to wait for someone else to bring us the things we wanted.

WWII took a huge toll on America, but it also galvanized this country and changed the way we looked at the world forever. Many of our adult males were killed, and those who returned from the war spawned the “baby boomer” generation. With so many men gone, women began to work in jobs traditionally held as “men’s work” and Rosie the Riveter changed the way we looked at women in the working class. With Eisenhower elected president, we began the most massive investment in roads and infrastructure in history. Seeing how effectively the Germans were able to move their tanks and troops using the Autobahn, we invested in the Interstate to promote travel and commerce. The unexpected side effect, however, was urban flight. Rather than investing more money in our cities, we spent our tax dollars on suburbs. Cities became a place to work: dirty, gritty, seedy places to work and play, but not the place to raise a family. This decline continues in some cities today. The result is a crumbling of American roads that feed these cities, due to decreases in our tax base, while at the same time, traffic using these roadways has continued to increase as more people live farther away from the urban centers in which they work.

In America, we have 4 million miles of roads. That is enough to circle the globe 160 times. Americans drive 3 trillion miles every year. And we can’t keep up. Cleveland may not be seeing the gridlock and traffic snarls that are the daily grumble of New Yorkers or residents of Seattle and LA, and we should count our blessings. In fact, on average, most Americans spend 44 hours a year sitting in traffic. Worse still, the roadways that we are sitting on are not in great shape. In fact, some 33% of our roadways are listed in mediocre to poor condition. And it is getting worse. When we built most of these roads, they were meant to last about 50 years. Today some two thirds are 40 years old or older. That means that in the next decade, our problems are just going to get worse.

Clevelanders know first hand the issues that we face. Commuters are dealing with the eventual shut down of I-90, as our major bridge across the Cuyahoga is in sad shape. If you live in Tremont, then you know the impact that local retailers and restaurateurs are feeling, as their on ramps are being closed off. This story is all too familiar around the country. The main E-W roadway in St Louis (I-64), could no longer be safely patched and has had to be completely closed and rebuilt. The economic impact on our country as we can no longer efficiently move goods from city to city is resulting in untold loss. Efficient transportation in other countries like China, only adds to the attractiveness of relocating manufacturing to these places.

What do we do? First, we need an injection of capital into our railways and roadways. In order to make our roads ready for the growth that we all want in this country, an investment in our transportation systems is necessary. Furthermore, we need to start rethinking the commuter model. We need to start returning to the cities that we work in. We need to make public transportation efficient, reliable, and attractive to the masses. We need to make the tough choices in order to make living and working in the same town a viable option. I remember being at a public meeting for the Port Authority as it discusses it relocation options and redevelopment of the waterfront. It amazed me that no one was interested in improving the public transportation to downtown or the waterfront. At the same time, there was applause when one resident demanded we provide free parking in downtown. This is the kind of mindset that has put us in the situation we are in today.

Like most Americans, we were a two car family. There were only the two of us, yet we felt we needed to each have our own car. As we started our business and no longer had to commute, we sold one of our vehicles. As sustainability became our mantra, we continue to reduce our travel. We drive less. We combine trips. We spend more time in our own neighborhood and shop within walking distance when we can. Surprisingly, this is becoming easier and easier. We buy a tank of gas every 3 weeks or so. This may not work for everyone, but until we strive to go back to the model of dense urban neighborhoods and public transportation, we are only going to add to our problems with our roadways. Rethinking commuting not only makes good economic sense, but environmental sense as well. Hybrids and electric vehicles are going to have a huge impact on our CO2 output, but these cars are not cheap. The average gallon of gas produces about 14 pounds of CO2. Cleveland has about 450,000 residents. If each resident drove about 15 less miles a year, that would result in a ball park figure of 2000 tons of CO2 emissions every year. Now imagine the savings we went back to living in our cities and taning public transportation….

Blog Action Day

Thursday, October 15th, 2009

Today is Blog Action Day, where all bloggers are encouraged to write about one single issue in the world today to raise awareness. As I approach the anniversary of the Great Lakes Green Pages, I wonder what is the one issue I should concentrate on. The result is that there are just too many. Instead, since I generally write about issues to raise awareness, I decided to list just a few of the many issues that are close to my heart.

Recycling, litter and garbage: Let’s face it, we are awash in garbage. We have chosen cheaper and cheaper packaging that doesn’t break down in the landfill. After nearly four decades of awareness of litter problems, we still haven’t learned. We like to think that we are the greatest country in the world, but we continue to follow the leadership in Europe on recycling, reuse, and waste reduction. We live in a throw away society, and are filling our planet with garbage at an alarming rate. We continue to tear down perfectly good structures, rather than rehabbing and make them usable, generating more garbage.

Poverty and hunger The world is growing. The population is increasing. Our resources are not. We have been the richest most prosperous nation in the world after WWII. Still, we haven’t figured out a way to make sure that every citizen in our own country has food to eat. Furthermore, our reliance on corporations for our food supply has lead to limited availability of nutritious food in poorer neighborhoods. What food is available, it is more expensive. Eating healthier is much more expensive than eating poorly, which leads to those who have less resources to have more health issues.

Education Our education system in this country is failing us. We are continuously graduating students who do not have a basic understanding of history, math, economics, etc. This leads more people to be uninformed on the issues that are facing us. Those who are well educated continue to hold the power over the undereducated.

Crumbling US infrastructure
We have stopped spending adequate money on roads, bridges, and transit. That means that many of the structures around the country are crumbling and falling apart. Hard to believe? Look around Cleveland. How much concrete fell off the Fulton Street bridge before it was closed. Anyone who went to the zoo for the decade before it closed can attest to how scary it looked as chunks would fall day and night. The I-90 bridge is dangerously damaged. Rather than jump right on it, we are closing lanes and on/off ramps to try and prolong the inevitable until we have just the right plan in place. All the while, I fear a collapse the size of Minneapolis.

Global Warming We are pumping CO2 into the atmosphere at a rate so high that we may not be able to recover. Still, we are on our third or fourth generation of Hummer.

Endangered Species Tons of animals are disappearing every day due to habitat destruction, over fishing, over hunting and poaching.

With so many issues affecting us every day, what are you gonna do to try and help the situation that we have gotten ourselves in.

Water: America’s Infrastructure Part 1

Wednesday, September 30th, 2009


One of the world’s truly most precious resource is water. While we are busy flushing most of our drinkable water down the toilet, or using thousands of gallons on our lawns, some people do not even have access to this most basic necessity. What is really scary is the amount that is being lost every single day in our cities that few people even know about. Today there are leaks in the water delivery systems in most major cities. While there is no clean drinking water in some cities in third world countries, we lose nearly 6 billion gallons each and every day due to leaks in our water systems. New York City loses 10% of its water every day to leaks. In Atlanta it is 14%. In rust belt cities, the problem is even worse; Buffalo, NY loses a whopping 40% of its water supply to leaks. There are an average of 240,000 water main breaks every year in the United States. We have had more than a few right here in Cleveland. The amount of water lost every time this happens can be devastating. In cities like ours whose infrastructure is failing across the board, this influx of water overloads the sewer systems, sending untreated sewage into water ways like Lake Erie.

And that is only the beginning.

The loss of water in a water needy world is terrible to be sure. However, the problem is bigger than that. In some cities, the loss of water pressure due to breaks and leaks means that fire hydrants are not properly pressurized. Should there be a major fire in some area, there is a possibility that there will be no nearby hydrants to apply water to the fire. This makes water pressure more than a luxury issue.

Couple that with the health issues associated with leaks. Micro fractures may allow water to leak out, but it also allows contaminates to get in. Remember the cryptosporidium outbreak a few years ago? In 2008, there were 2 boil alerts issued around Washington, DC. That means that twice in one year, the drinking water was unsafe to consume in the water district. We are not talking about India or some developing country, we are talking about the suburbs surrounding our nation’s capital. In some regions of the US, homes are built with septic systems. Some homes in this same region may be supplied by wells. Normally not an issue, but if there is any water main collapse or major line leakage, water supplies can cause sepetic systems to discharge water that is contaminated by e. coli and other bacteria into the same watershed that is being used to supply water.

Consider NYC. Residents of the Big Apple consume 1.2 billion gallons of water every day. Most of this water comes from underground pipelines and aqueducts from up to 100 miles away. The main aqueduct for the city is over 80 miles long and about 70 years old. It hasn’t even undergone a thorough inspection since 1957. Engineers fear that if it is shut off for inspection, the loss of pressure may cause the entire line to collapse. Estimates are that somewhere between 10 and 36 million gallons of water are lost every day to leaks in this line. The worst are centered around a small town in NY called Warwarsing. The cracks in the pipeline are so bad here that the water is rising to the surface. If you have every seen a sinkhole develop, then you can imagine the problems that this town is experiencing. If there is ever a collapse, it is estimated by some that the entire town will be destroyed.

So while there are Californians thinking we need to help supply them with fresh water from the Great Lakes, I say think again. If we could only stop the leakage of 6 billion gallons of water every day from the drinking water supply chain, then we could supply most of that state with its drinking water from the savings alone!

update…
I got this email from one of my readers, so I thought that I would add it on. There is work being done after all to alleviate NYC, but what about the rest of the country?

In response to your water post, please view the attached link: http://en.wikipedia.org/wiki/New_York_City_Water_Tunnel_No._3

If you are not aware, New York City has been working on a tunnel since the 1970′s to help alleviate some of these issues.

This would be the 3rd tunnel for NYC water use.

You make some very good points here. I look forward to your next post.

Save 39,000 gallons of water every year!

Thursday, September 24th, 2009

As you might have noticed, I had to work on my blog. There was a hack into my blog site, which required me to learn all about SQL databases. In the end, I went for a complete new install of the latest software, which didn’t work too well with all my existing files. I think that I have all the kinks worked out now. In the interim, I have been thinking about how important water is to us, and how we take it for granted all too often. While you may think oil is our most precious natural resource, water is the basis for life as we know it on the planet. Check out this video from Kohler:

Much of the world’s population doesn’t even have access to clean drinking water. Developing countries often have to use the same water to drink, bathe, wash clothes, even as a sewer. But here in the US we flush most of the water that we use. Another husge amount goes to providing us with that nice green lawn that we are so proud of…

For a few tips on how you can cut back on your water usage, check out this video…

A family of four can save 39,000 gallons of water a year!
