2nd Green Revolution - Part 21

Common Misconceptions about Alternative Energy Sources

While alternative energy sources seem to be the in-thing today, not all the press it has gotten is good. Everything has pros and cons. However, it’s just as important to distinguish fact from fiction when weighing common perceptions about alternative energy. Here are some of the most common misconceptions:

They are always cheaper than non-renewable energy sources

Misconception: Sources of renewable energy can provide savings. However, the operative word is “can.” For example, various vehicles on the market today use a blend of renewable and non-renewable energy sources. The cost of such hybrids can range from about $23,000 to over $60,000. This is based on several factors, such as whether the vehicle is a sedan or an SUV, whether it’s a basic model or one with tons of extras, and so on.

Fact: The initial cost of using renewable energy sources are typically higher than when using non-renewable energy sources. Consider that a “hybrid” vehicle can have a price tag that’s $10,000 or more than a comparable vehicle that operates exclusively on gas. Also, consider that hybrid vehicles still use non-renewable energy sources. So, due to the technology available, there’s somewhat of a compromise when choosing them. The good news is that sources of renewable energy can indeed pay for themselves. However, this is based on several different factors. How much of the energy source is available? What’s the initial cost of the energy source? How much energy is needed? Such factors will determine the bottom line when using sources of renewable energy. For example, an 8-kilowatt solar panel system can cost $70,000 USD or more. So recouping the initial costs could take decades.

They never produce any pollution when we use them

The Green Apple: Who Will Be the Steve Jobs of the Clean Energy Sector?

Yesterday, I briefly attended the CEATEC exhibition in Tokyo that focused on electronics and had a lot of green technologies on display: solar panels, EV charging stations, new energy efficiency measures, and even a planned sustainable community. What was lacking, however, was a whole other type of electricity- the electric atmosphere found at certain events where the audience knows something exciting and new and big is taking place; the electric atmosphere that accompanied an Apple event led by Steve Jobs, for instance.

As the remembrances, accolades, and reflections on his life and work pour in, let’s remember that Steve Jobs and Apple were so successful by making cool, quality, breakthrough products that people wanted. By loving his work, making beautiful products that were easy to use, and striving to match the visions he had in his head, he became the spokesperson for how these devices could make our lives better.

Steve Jobs wanted to have an impact on the word, and he unquestionably did. Now where do we go? Think different? We need too. For all the innovation and disruptive technology Apple brought us, the truly enormous leaps in human society are still waiting; an economy that doesn’t run on oil, for one. Who will bring passion and simplicity and excitement to the products and services that will transform us into a sustainable society? Who will turn the tide and push the boundaries – behind the scenes and in public – to create and sell the green technologies to a consumer base who, at least according to Jobs, is not supposed to know what it wants? Will someone come along who will make sustainable gadgets the must have items? Who will be the Steve Jobs of the clean energy sector? As a kind of remembrance, the following post from March of 2010 begs that question.

Whether you love him, hate him, or are indifferent, Steve Jobs has major street cred. His company makes products that are elegant, well-designed, easy to use, and revolutionary. The hype and excitement that accompanies the lead up to and release of a major Apple product is second to none. Not only that,

University of Maryland Wins the 2011 Solar Decathlon

Much like the World Track and Field Championships, which are held every other odd-numbered year and boast the world’s greatest athlete (i.e. the decathlon winner), the Solar Decathlon in Washington D.C. also takes place biannually on years ending in odd numbers. Two years ago, the team from Germany was victorious for the second straight competition. This year’s Solar Decathlon yielded a hometown winner. Nearby University of Maryland was announced as the victor by U.S. Secretary of Energy Stephen Chu.

The competition, which took place from September 22nd through the first of October, featured 19 teams. Many of the competitors were from universities in the United States, although there were several international teams as well. The “Department of Energy Solar Decathlon is an award-winning program that challenges collegiate teams to design, build, and operate solar-powered houses that are cost-effective, energy-efficient, and attractive. The winner of the competition is the team that best blends affordability, consumer appeal, and design excellence with optimal energy production and maximum efficiency.” The competition was first held in 2002

Five Friday Facts: Sewer Water, Drought, and San Antonio

Even in the middle of a historic drought, San Antonio, Texas has managed to keep the San Antonio River flowing through the River Walk area of downtown. What’s their secret? Treated sewage water. Here are a few facts from an NPR article on the river.

  • To keep the river flowing, the city used to have to pump up to 5 million gallons a day from its precious supply, the Edwards Aquifer. Now, by using a state-of-the-art water treatment plant, the city produces high-quality, recycled water that’s just shy of being drinkable.
  • San Antonio’s River Walk is not alone in using the treatment plant. Big industrial customers like the Toyota manufacturing plant, Microsoft Data Center, USAA Insurance and the city’s golf courses also take part. More than 60 miles of recycled-water pipeline built in the last decade now snake through San Antonio.
  • The plant is hitting it’s goal to save a billion gallons of water every single year.
  • The number of gallons per consumer in San Antonio per day that is used has gone down from just over 200 to about 130 over the last two decades.
  • As important as the conservation is, what’s really saving San Antonio right now is its aquifer-storage system. During times when the rains are plenty and the Edwards Aquifer is full, San Antonio aggressively pumps the water out and stores it 40 miles away in a sand formation  called the Carrizo. Nobody knows how much water the Carrizo could ultimately store, perhaps as much as 65 billion gallons.

Review of Organic IPA from Eel River Brewing Company

After a long lay off, Revolutionary Spirits returns with its latest column reviewing a beer from Eel River Brewing Company (ERB), the first certified organic brewery in the United States. ERB is nestled in the town of Fortuna, in Humboldt County, California. Humboldt County is traditionally known for another type of herbal refreshment, however it is now home to a number of award winning craft breweries (interestingly enough, all containing “river” in their names). Started in 1995 by home brewers and friends Ted Vivatson and Margaret Frigon, ERB began winning national recognition and hardware a mere two years after its incorporation by snagging the Silver Medal at the Great American Beer Festival for its Ravensbrau Porter. In 1999, they started brewing their organic Amber Ale, and have since added six other beers to their organic repertoire.

The beer on review is ERB’s Organic IPA, poured from a 22 oz. bottle. The beer poured a cloudy golden orange/copper, not unlike a brand new penny; it created some decent, if not thin head, but left solid lacing. It smelled a bit earthy with citrusy sweet overtones, similar to fresh cut young pine. The IPA had very good mouthfeel, low carbonation, smooth, not syrupy, as a more carbonated cask ale would have. The taste is

Book Review: Alice Waters’s Edible Schoolyard

Toward the end of the summer I started reading Alice Waters’s Edible Schoolyard: A Universal Idea from Chronicle Books. It’s not long, but it is powerful. Waters is the proprietor of Chez Panisse, a restaurant in Berkeley, California that focuses on local, seasonal, and organic ingredients. In addition, Waters is a former teacher at a Montessori school in Berkeley. After seeing what she thought was an abandoned schoolyard, Waters got involved in creating a garden at Martin Luther King Middle School, which serves as the impetus for the book.

Over the course of several years, numerous people, including the school’s principal, many of its teachers, students, a master gardener, and others worked tirelessly to transfer a one acre plot of land from an asphalt patch turned garden turned outdoor classroom brimming with produce.

The following represent the principles of edible education:

MIT Invention Harvests Energy from Vibrations

Bridges, overpasses, walkways…we’ve all felt the rumble or the shaking as people and vehicles cross these structures. Slightly nerve-wracking and sometimes annoying, is there any real use for these vibrations? After all, it is a form of kinetic energy. MIT has thought outside the box yet again to rig up a miniature energy-harvester that can pick up the low-frequency vibrations produced by a bridge and convert them to electricity. That electricity can then power wireless sensors that measure the strength and condition of the bridge. These wireless sensors are being used more and more to monitor everything from oil pipelines to pollution to factory machines.

Batteries in these sensors need to be charged every so often, even though they have become more efficient over time. Wouldn’t it be nice to do away with batteries all-together, or let the device charge the batteries itself? We may be on the way there. Here’s how the MIT blog put the invention (full, more technical explanation here):

Researchers at MIT have designed a device the size of a U.S. quarter that harvests energy from low-frequency vibrations, such as those that might be felt along a pipeline or bridge. The tiny energy harvester — known technically as a microelectromechanical system, or MEMS — picks up

Los Angeles to Build 1st Carbon Neutral Stadium

Several past posts have dealt with the idea of sports stadiums and arenas. Some of these have highlighted the advancements in green building techniques that have been incorporated into the design and construction, including LEED certification for numerous facilities throughout the country. In hopes of luring a football team back to Los Angeles, the Anschutz Entertainment Group (AEG) has been in the process of getting approval for a stadium in downtown Los Angeles, near their own Staples Center, which has a vast solar array on its roof.

In order to expedite the permits for building the new stadium, California Governor Jerry Brown, signed legislation that will fast track any legal challenges in exchange for a carbon neutral stadium. According to ESPN’s website, “In exchange for an expedited legal review, AEG has pledged to build a carbon-neutral stadium with more public transit users than any other stadium in the country and has committed to making Farmers Field one of the only stadiums in the country to have a net-zero carbon footprint.”
