Energy Saving Curtains – I’m Loving Mine So Far

This week, the temperatures here in San Antonio dropped from a pleasant low 70s/high 50s range to yesterday, where the high was something like 48 and the lows got into the 20s.  Which means this week was my first chance to really test out how my new Energy Saving curtains really worked.

I love them.

Not only do these things block noise, which gives me a better night’s sleep, but the heater isn’t coming on nearly as much.  I haven’t got my new utility bill yet, but I know it’s going to be less – it’s that obvious. 

There are negatives, of course.  In the bedroom, I replaced some very pretty Battenburg Lace curtains with these babies, and the new ones are not as pretty and there’s a lot less light now.  I didn’t buy full blackout curtains, but these “energy savers” do make the room lots darker. 

This can be solved by a tie-back or two, so I’m not that concerned with this issue.  Truth be told, at night the thicker curtains make the room much cozier for sleeping than the lace curtains did.  I’m losing the beauty of the sunlight coming through the lace to get this, but right now I’m okay with it. 

I’ll keep you posted on what the utility bill does this month and next month, too.  I’ve been these curtains in most of the house now, so there should be a big difference. 

Cooking With the Sun: Solar Ovens

The first time I saw a solar oven was on Ed Begley, Jr.'s television show, "Living With Ed," and it looked like a cool science project -- no wonder Ed is friends with Bill Nye, the Science Guy (who's guested on Ed's show). Something fun for the kids sort of thing -- but now, with oil prices soaring, meaning electricity is costing more and more ... well, maybe solar ovens are something I should ponder more seriously.

Come to find out, solar ovens come in all shapes and sizes, and you can make one from some pretty cheap materials as well as buy one, ready-made. SolarCooking.Org gives all sorts of examples - square ones, round ones, collapsible ones, there's even one with dual settings.

Last year, America's Test Kitchen's Chris Kimball (the guy that's so hard to please) tried out several solar ovens for CBS's The Early Show --- he roasted a chicken, made some chocolate-chip cookies, and cooked up some rice along with some broccoli. The result? Stuff that slow-cooks well tends to be best for solar cooking: the roast chicken turned out well. The broccoli never made the grade. Seems there are variables to contend with: clouds passing over, the amount of sunlight available (10 to 2 are the best times, and some months are much better than others, you get the idea). The cookies? They did okay.

The USDA warns that "solar box cookers" may not get foods hot enough, or fast enough, to be safe from bacteria and suggests that everything be monitored with food thermometers. (Their microbiologists are concerned with how long foods stay in the "Danger Zone" of 40 - 140 degrees while in a Solar Box Cooker.)

Manufacturers are almost zealots in the marketing of their solar oven products. SunOvens sells its model for $279 online, and promotes its product as not only reducing one's energy footprint, but also helping rebuild deforested areas as well as women and children in developing countries.

You can also buy the Sport Solar Oven from the non-profit organization, the Solar Oven Society. It's $150.00 (includes shipping) and only weighs 10 pounds.

Finally, you can make one of these things pretty darn cheap. And easy. There are lots of sites that give instructions for this, but my favorite has to be the Pizza Box Solar Oven made by students at Union Elementary School in Montpelier, Vermont. Their site shows the kids lined up with their Pizza Box Solar Oven, and gives detailed instructions on how they did it. Maybe you can't roast a chicken in one of these things, but their mention of English Muffin Pizzas and S'Mores sounded like lots of fun ...

Six Ways to Keep Your Home Cooler For Less

1. Plan meals to avoid using the oven. Invest in more than one size of slow cooker, as well as toaster ovens, George Foreman grills, and/or Panini presses, all of which avoid heating the entirety of the kitchen. Grilling outside is another option, and it’s fun, too. And, remember, whether you’re cooking indoors or out, always make more than you need so you can use the leftovers during the week.

2. Rearrange your rooms to fight the heat. Warm air is less dense than cool air, and it rises. Your second floor will be warmer than the ground floor, and your ground floor will have more warm air than the basement. Then, there’s the sunlight bombarding your house to consider. Insulation from the heat keeps interior rooms cooler than the ones exposed to sunlight; plus, the room sharing a wall with the garage will be warmer than any interior room. Fight the heat by finding which rooms are naturally located to remain somewhat cooler than the rest. Consider rearranging your rooms accordingly: if the formal living room will be cooler than the great room next to the garage, then start using the living room for everyday activities. If the guest room is located better, cooling-wise, than the home office, ponder switching those two rooms. Make it a family habit to keep doors shut between rooms, so you can have some rooms cooler than others, and block off vents for rooms that are not needed every day. Don’t let the traditional uses for your rooms control your thinking: it’s your house, do what’s best for your family even if it’s unconventional.

3. Position furniture to maximize cooling. Move your furniture to maximize airflow: a sofa pulled away from the wall will get more air circulation than one backed against it. Bookshelves, filing cabinets, armoires, entertainment centers, even tapestries and a wall of framed photos provide added insulation for a room.

4. Use stand fans and box fans. Incorporate stand fans, or box fans, where you'll spend the most time. Stand fans usually come with remote controls and multiple speeds. Some are generic white plastic, but more and more stand fans are becoming available in designer treatments (Cottage, Art Deco). The new ones are much quieter, too. Why fans? Flowing, moving air will make you feel cooler.

5. Heat-proof your window treatments. It can be hard to sacrifice that great view through a big, clear window or patio door, but glass is far from the best insulation – even if it is double-paned. Covering windows can make a big difference in keeping rooms cooler, and it doesn’t have to cost a lot to do so. Mini-blinds can be purchased for less than five dollars per window, and can make a big difference on how cool room will be on a hot afternoon. For a little more, you can buy mini-blinds that are specifically made to help with heat, as well as draperies specifically designed to block a blinding hot sun blaring into a room on a hot, summer afternoon. The room will be darker, and you may lose that view, but the goal of keeping the room cooler before you start spending your budget’s electricity dollars will be met.

6. Use room air conditioners instead of the central system. Use room air conditioners, or portable air conditioners, rather than a central air-conditioning system, cooling only the rooms that you actually use. These units come with timers and thermostats, which allow you to coordinate cooling the rooms only when it will be needed. For example, bedroom room air conditioners can be programmed to start up and run for approximately 2 hours before bedtime, with the thermostat automatically controlling the air temperature of the room throughout the night. Portable air conditioners can also be used in the den and home office when needed. The central system can be ignored, or its thermostat set much higher than in previous years: 88 degrees, for example, with only the den and the bedrooms kept at 78 degrees in the evenings with room air conditioners, and unused rooms having closed-off vents, is a comfortable environment and much less expensive than the central system being used for all your square footage.
