Representative Jay Inslee (D-WA) has introduced legislation to establish a feed-in tariff (FIT) for renewable energy. Feed-in tariffs have made Germany a solar powerhouse that employs 40,000 people in the solar industry alone, and an estimated 140,000 jobs in renewable energy. FITs have not been a topic of discussion in this country, but now that is sure to change, as the conversation shifts to ways to finance the growth of renewable energy. Renewable Energy World reports that:

“Inslee’s legislation would require utilities — at the request of any new renewable energy facility owner — to enter into a 20-year fixed-rate power purchase agreement. Uniform national “renewable energy payment” rates would be set by the Federal Energy Regulatory Commission at levels that would provide a 10% internal rate of return on investment for available commercialized technologies in regions constituting the top 30^th percentile of renewable energy resource potential in the U.S..”

In plain English, this means that if you install solar PV panels on your home, the utility has to buy the electricity you generate at a higher rate than retail, guaranteeing you a return on your investment. Extending this power purchase agreement for 20 years gives everyone — especially those who want to invest in renewables or start a small business installing solar panels — assurance of return on their investment.

A location often dreamt of in my household, for its summer weather and prime surfing, Hawaii now goes up another notch in my estimation with the passing of a bill which makes it mandatory for water heaters to be powered by solar energy.

Signed in to law by Governor Linda Lingle (there’s a name for you), a republican, the bill requires that the energy savers be part of the new home landscape starting 2010. It prohibits issuing a permit for building a single-family home without a solar water heater, and for a state that relied on imported fossil fuels more than any other American state, this can only be a good thing.

Hawaii manages to import about 90% of its energy from foreign countries, according to state data.

The Energy Star Washing Machine vs. The Wonderwash vs. The Basin vs. The Future of Home Dry Cleaning

In this 4-way battle royal to earn the title “The Best Washing Machine for You and the Earth According to Joe”, a variety of factors need to be considered. Water use, electricity use, size of family, and–of course–convenience all need to be given a good look. And even though I am of the mindset that we have way too many unnecessary conveniences in our society, I am aware that some conveniences have proven to be beneficial time savers.

In reading for this post I had to turn to No Impact Man to see what his thoughts were on the subject, because, unlike my familiarity with the reel mower, I have never used an alternative to the washing machine. I was surprised to learn his thoughts.

The laundry machine is the one appliance I believe makes the difference between a life of drudgery and not. If cars are the Devil, as I think they are, then laundry machines are God. Read the rest of this entry »

Back in late May, I shared some information about the Medis 24 x 7 PowerPack, a fuel cell that charge a variety of electronic devices through the use of interchangeable tips. Last night I noticed an story on CNET’s Crave (”the gadget blog”) about a new application for the cell. It described an LED flashlight with an adapter to plug into a PowerPack that can operate for as long as six weeks on a single fuel cell.

As far as green gadgets go, this little desktop computer will give Dell and (to a lesser extent) Apple a run for their money.

The CherryPal promises to be affordable, efficient, and powerful enough for the average PC user. At first glance, that stats on the system look modest, and for good reason. This design actually cuts out 20% of PC components to reduce energy usage. But fear not, despite being small (the size of a paperback), the CherryPal claims it can start up in 20 seconds, and cloud computing provides more power/storage when you need it. A Linux operating system (now more user friendly than ever), and cloud computing means you won’t need to worry about viruses or install protective programs that can slow down your PC.

It started with a long discussion betweeen my wife and me. We each thought it’d be fun to get a scooter, but worried that, for us–a 1 car, 2 bike family–we would actually be doing more environmental damage by getting a scooter. Meaning, unlike many who get a scooter to use instead of their car (wise choice), we’d end up using our scooter instead of our bikes (un-wise choice). Being our primary mode of transport, the bikes would likely fall victim to the newer, sexier, faster scooter.

This got me on the thought process that I wished more people would first give a bike a try for their short trips, instead of viewing the scooter as their only alternative to combat gas prices. Of course it’s more work–but more work can be more rewarding. Which got me to thinking that there are plenty of tools that have traded elbow grease for electricity–yet we have benefitted little. Which turned me on to this mini-series…

Just as John Henry fought the steam hammer to show that human power cannot be undone by the industrial revolution. I am hoping to open a few eyes to the alternatives that are possible when we replace one of our everyday machines with the same machine sans motor/electricity/etc.
In the interest of full disclosure John Henry did beat the steam hammer but he also dropped dead in the process.
That said, I will be realistic with my comparisons–I don’t want anybody to drop dead of exhaustion. I’m sure I’ll find, in some cases, the modern invention to be more beneficial to the manual powered version it replaced.

Not exactly washing without water, but with less than 2% of a normal washing machine. That’s only 1 cup of water for those sweaty gym clothes, grubby kid-wear, and foul socks.

Washing with soap and water has been THE WAY to clean most clothes for so long, it’s hard to imagine reducing H2O by 98%. What this technology lacks in sexy bells and whistles, it gains in implications. Billions of gallons of clean water could be conserved every year simply by adopting this dry cleaning technology. Less water also means less drying, which can add energy savings to those with energy-hungry clothes dryers. Read the rest of this entry »

(Quote shamelessly borrowed from Star Wars via Lucasfilm Ltd.)
There’s a basic law of physics that everyone can agree on: you can’t create energy from nothing. So when an invention comes along and seems to do exactly that, scientists are skeptical. Some get downright prickly. The problem is, these inventions exist, and everyone who looks at it agrees: it works.

Fortunately, no laws of the universe were harmed in the making of this device, though Star Wars geeks like myself could have reason to rejoice.

The Dark Side

The idea stems from some of the most bizarre, puzzling, and dark corners of Physics, specifically Quantum Physics. Here’s the very basic idea: there is energy/matter everywhere in the universe, even the deepest, emptiest depths of space. Since there’s almost no normal energy/matter in the deepest, emptiest depths of space, the fact that all that space exists (and is expanding) means that it must be filled with something. Enter Dark Matter/Dark Energy. It is believed to exist everywhere in small amounts, but since it fills the universe, that means that there’s A LOT of it - as close to infinity as you can get. While this matter/energy is not literally “dark” in any sense of the word, it does prove that energy exists everywhere, and that it affects normal matter so that (in theory) we could use it.

I ran across this article at The Oil Drum and thought it was too tasty to pass up. It describes a new design to help concentrated solar power (CSP) increase efficiency and reduce cost.

Here’s the problem: solar thermal collectors focus the sun’s heat onto a clear tube of fluid (see: Intro to Solar Thermal). The collectors generate the most energy when the sun’s rays are parallel with the tube of fluid.  Since the sun moves across the sky throughout the days and seasons, it only reaches this “sweet spot” certain hours each day. But, if the solar collectors could move to track the sun, their power output could increase dramatically. Keep in mind that CSP is one of the most efficient forms of solar power.

Many people envision solar power as rigid silicon panels mounted on a roof. With thin film solar cells, you’re more likely to not see them, or even know they’re there. This article is about a real-life thin film solar project.

Not many bloggers are able to witness the technologies we research and write about. It’s one thing to be able to buy afford a cool “green” gadget (usually not very green), but another to see the many forms of solar, wind, geothermal, etc., which are always changing and developing around the world. So when my employer decided to go solar, you might imagine my excitement.

At the moment I work for Magco Inc., a Tecta America company. Tecta is a national commercial roofing corporation that can install green roofs, solar lighting, and solar panels alongside a variety of traditional roofing systems. This solar project is pretty straight forward: our building has a big, flat roof on top of a hill without any shade. You’d have trouble finding a sunnier spot for solar panels.

I was double delighted when I heard that they ordered thin-film solar! Naturally inquiring minds wanted to know: why and what kind? Read the rest of this entry »
