Solio Mono-i Solar Charger
As we’re entering Spring, even in Seattle, we ought to start seeing a bit more sun. And nothing would show our gratitude for the change in weather than for us to actually harvest it’s potential with a solar charger.
Sold in a variety of makes and models, these little gadgets collect energy from the sun for your personal appliances. Be it a laptop, an I-Pod, or a cell phone, you can easily find a solar charger out there to match your needs, even essentially universal ones with a multitude of different plugs. One that’s caught my attention recently is the Solio Mono-i. The company boasts it’s compatibility with 3,200 devices, and also lists the other features typically found on a variety of such chargers.

Winter: tis the season to be jolly. Christmas and Valentine’s day have already come to pass, but the season hasn’t lost all of it’s festivities for those of us enjoying the Winter Olympics. Some time during the beginning of each month though, in spite of how joyful the season may be, you’re bound to get an envelope in the mail that’ll bring you down from all that cheer. Inside the envelope, you’ll find a letter with a lot of fine print and a very clear number representing how much money will be going to go towards paying off the additional heating expenses that every Winter brings along with, the Winter hangover.
Environmentally sound technology has advanced though to the point where you can stay warm in-doors without paying as much of the annual extra costs of heating utilities and without causing unnecessary harm to the environment. It’s a win-win situation in the form of a window material that won’t even clash with your drapes.
The technology is called Low-emittance coating and is applied to the glass during the manufacturing process but the science behind it is pretty simple. When your home is warmed up, eventually things will cool down (it’s why you have to keep the heater on over extended periods of time) as the heat radiates. The heat leaves in the form of infrared radiation, and these microscopic layers work to prevent that by only allowing specific frequencies through. Best of all though, it can work both ways. So in the Summer the same coating that kept heat in during the winter, can keep heat out (diminishing the need to keep rooms regularly air-conditioned).

Winterize your Home for Energy Efficiency
Eco tips for saving money this winter. What works well in the winter, can also save you money on your cooling bills in the summer too!
The Little Stuff:
- Seal up cracks – Common spots for drafts are entryways (the back door and garage doors are notorious for draftiness) window moldings and seals. Caulking windows, sealing cracks and installing weather strips under doors will help seal out drafts accounting for big losses of heat.
*Be sure to add lots of indoor toxin removing plants to keep indoor VOC levels and off-gassing furniture emissions to a minimum. - Insulate your attic – Cold air sinks, and if your attic isn’t insulated, it’s dropping down on you like an invisible fog. Get some insulation up there pronto! When choosing insulation materials, choose something with a high ‘R-value’ and try and stay away from anything with formaldehyde. It shouldn’t be any more expensive, but it will be much better for your health and indoor air quality.
- Insulate your windows – Break out the heavy curtains! Blinds and shades can also do their part in insulating you from the chilly outdoors. When the sun goes down, close your curtains or draw the shade to keep the warm air in and the cold air out. Be sure to open them first thing in the morning to get that rising sun.
- Insulate your water heater - Unless its a newer Energy Star water heater, most water heaters can benefit from an insulation blanket. Try and cover the first 6 feet of the hot pipes as well for an added benefit.
- Adjust the thermostat – I know it’s difficult at first, but each degree set below 68°F (20°C) during colder weather uses 3 to 5 percent less heating energy than each degree set above 68°F. A programmable thermostat can change the temperature automatically for when you are commonly gone or bundled up in bed saving you from heating an empty house.
- Change your air filter – Often overlooked or performed once at the beginning of winter, you should change your furnace filter once a month during heavy usage to keep everything flowing nicely.
The Big Stuff:
- Add a storm door – A benefit of up to 2 percent savings on your annual energy costs can be › Continue reading
LED vs CFL vs New HEI Energy Efficient Incandescent – Lightbulb Shootout
With energy efficiency awareness growing, and new lighting technologies being developed at a rapid pace, which bulbs on the market offer the best value for the eco-conscious? With the more recent popularization of Compact Fluorescent Light (CFL) bulbs due partly to their electricity savings and partly from huge discounts and government energy rebates making them more affordable, we ask the questions: which is the best value, which has the best life, which is the most eco-friendly, and which puts off the best light? We set out to put them all to the test.
Light Emitting Diode (LED)
Growing LED technology is developing one of the most energy efficient, long lasting and versatile bulbs in history. Already replacing traditionally incandescent automotive bulbs, flashlight bulbs, monitors and televisions, the LED is quickly becoming the new standard in eco-friendly efficient lighting. Household and commercial light bulbs are still in their infancy with very few and very expensive offerings that for the most part cannot compete with current bulb offerings.
Average Lifespan: 60,000 hours
Energy Consumption: 230 lumens / 7 watts = 33.9 lumens/watt
Average Bulb Cost: $54.00
Pros:
- Cool to the touch
- Available in several shades and colors
- Dimmable
- Very high color spectrum or temperature (closely mimics daylight) at 4200k
- Extremely long life
- good for floodlights and direct, focused lighting
Cons:
- Price and availability
- narrow focus of directed light (almost like a flashlight in many instances)
- still in early stages of development for home lighting applications
Best Bet: Use in as low output uses such as nightlights, accent lighting and for directed and focused lighting situations, especially in difficult to replace areas
Whole House Lighting Control System
Great lighting can really make a house feel like a home. While we tend to focus on the energy efficiency and design of lamps and bulbs, often we neglect to consider the actual electrical system in the house. Whole House Lighting Control System by Verve Living Systems brings a whole new element to eco-friendly lighting.
A wireless lighting system that works via radio frequencies without the need for batteries, it works by routing all lighting to a programmable central controller. Each switch transmits a ‘blip’ of a radio transmission to the central hub up to 300 feet away, get this: by using the energy from the act of flipping the switch. That’s right, the switch itself powers the transmission without needing batteries or its own power source, so they are completely independent and self sustained units. This allows them to be mounted anywhere, you could even just carry it around in your pocket if you want.
By eliminating the need for light switch wiring and having a central hub to control lighting of the entire home, one can program an endless combination of lighting scenarios, and change it without having to do any re-wiring. The energy saving opportunities are equally as enticing. A one switch shutoff for the entire house so you won’t have to worry about that closet light you forgot to turn off.
Verve Lighting Control Unit
The benefits of the system are endless. Not only does it greatly reduce lighting install time, labor, and cost due to the lack of a need for wiring switches, but the switches can be installed anywhere, and moved at any time. The system is completely programmable, so you can change the operation of each switch, or group lighting elements together. Imagine turning on one switch and having your entryway, driveway and garage lights all turn on at once, and then be able to click a button in your car to just turn on the driveway and garage lights only.
Green Electronics
With so many choices for those looking to buy a new Television, laptop computer or other type of electronic device, why not take the environment into consideration when choosing?
Nowadays you can pretty much find four or five separate equally equipped 46 inch LCD HD televisions put out by different manufacturers. So when the specs are the same, the price is the same, why not pick the eco friendly company over the polluter? Greenpeace has come out with a Guide to Greener Electronics, and while its not perfect, it is headed in the right direction.
The basis for their ranking system is how the companies stack up when it comes to toxic chemicals in their products, recycling programs and climate change policies. While somewhat objective and compiled from cooperate website information, it helps form a reference point for companies committed to environmental stewardship.
7.1 Samsung – Holds second position for commitment to reduce absolute emissions.
6.5 Sony Ericsson – Up two places with better product energy efficiency reporting.
5.7 LG Electronics – Up two places but needs to eliminate hazardous chemicals from all products.
5.5 Toshiba – Moves up two places with an extra point for promising to cut GHGs.
5.5 Motorola – Scores higher and climbs two places because of use of renewable energy
5.3 Philips – Falls from 4th to 7th position and needs to put its commitment to responsible recycling policies into practice.
5.3 Sharp – Rises from 9th to joint 7th place with its energy efficient products.
4.9 Acer – Put out 16 new models of a monitor that are almost free of hazardous chemicals and climbed two places from 11 to 9 but still needs to sort out the power cord.
4.9 Panasonic – Advance from 12th to 10th place for energy efficiency and PVC-free product range, but still bad on e-waste.
4.7 Apple – Drops one position to 11th with no change in scores but gets kudos for their green MacBook.
4.5 Sony – Plunges from 5th to 12th place for inadequate commitments on eliminating hazardous chemicals, e-waste policy and cutting GHGs.
3.9 Dell - Stays at 13th place because of backtracking on toxic phase out.
3.5 HP – Is at 14th position and has no products on the market free of toxic substances.
2.5 Microsoft – Loses a point for a poor recycling policy but stays in 15th position.
2.5 Lenovo – Down two places with no set timeline for toxic phase out on all products.
2.4 Fujitsu – Debuts second from last with no products that are free of hazardous chemicals.
1 Nintendo – Stays put in last position with a glimmer of hope with partially PVC-free consoles.
Another website out there helping to make a difference is the Green Efficient Guide. Here you can look up energy saving televisions and compare them by their power use, making sure you get the TV that uses the lowest amount of electricity. They also track the standby power of these televisions, since no electronics are actually ‘off’ anymore.
You can even calculate the yearly cost of the television or electronics you choose by entering in the average amount of television you watch a day. You can even factor in whether or not you have a vampire energy-killing power strip.

New Solar Panel Powered Stadium in Taiwan
A beautiful integration of renewable energy and modern green design, the recently finished solar stadium in Taiwan will welcome the 2009 World Games to 3,300 lights and two jumbo screens all on 100% solar energy. Designed by Toyo Ito, the 14,155 sq meter roof consists of 8,844 solar panels generating 1.14m KWh (that is 1.14 gigawatt hours of electricity) a year.
When not powering the stadium lights, the power will be funneled into the local power grid and is expected to meet almost 80% of the neighboring area’s energy requirements. It is estimated that this stadium will prevent 660 tons of carbon dioxide (CO2) a year from being released into the atmosphere when compared to a traditional powered stadium of this size.

Can I Recycle This, and Where?
I have this happen to me all the time. Random electronics, toys, packaging, home remodeling projects, etc. I don’t want to throw it away, but can it be recycled? Real Simple has come up with a great A-Z guide to recycle just about anything, and gives you the information you need to find a recycler in your area. Their list is pretty complete, however I have a few additional resources for some specific items- mainly clothes and denim jeans.
Probably the best way to recycle clothes is to take them to your local charity that accepts donations. Goodwill, The Salvation Army, and many other large scale donation resellers will bundle unsellable clothes and sell them to textile recyclers who then make them into industrial rags. Alternatively, recycled denim is becoming an increasingly popular form of insulation in new and remodeled homes.

Energy Active Eco Home- Taking Energy Efficiency Positive
This technologically advanced home boasts a computer controlled system that regulates the home like a human body. Monitoring temperature, seasons and the time of day to maximize efficiency, this home is an energy over achiever- creating more energy than it uses. While this may sound futuristic, it’s happening right now, in a cold and cloudy Lystrup, Denmark in fact.
Increasingly popular in the U.S., Passive Houses are energy efficient homes that mitigate power through the use of solar, wind or other renewable energy sources. These homes are becoming the standard throughout most of Europe prompting a new frontier of energy Active Houses. These Active Houses are highly efficient homes that captures more energy than the occupants need for heat and power and require not only super efficient building techniques and materials, but also onsite renewable energy sources.
For eight months a year, the solar cells produce excess energy to sell to the grid. In the winter months, the house buys back electricity – from renewable sources, of course. When a mass-market battery car finally reaches the market, there will be a charger for it in the garage and energy to spare.
Carrotmob Mobs Seattle for Sustainable Businesses
I am pretty excited about the first (of hopefully many) Carrotmob event at the Pike Place Place Brewery in Seattle, Washington. If you haven’t heard about Carrotmob, you should check out their website and get hooked into their sustainable consumer network.
Carrotmob organizes environmentally conscious individuals to reward businesses for being eco-friendly. One way they do this is to funnel large amounts of consumers to patronize a single business which has promised to become more sustainable. The means is negotiated beforehand by the Carrotmob team, which can range from upgrades to make a business more energy efficient, to converting over to renewable energy.
The first ever Carrotmob event in Seattle happens TODAY (sorry about the late notice) April 22, 2009 in tandem with a Seattle Greendrinks event at Pike Place Pub and Brewery.
