Harley Goes Electric

In a sign that likely bodes well for the future of electric vehicle, Harley Davidson is testing a prototype, Livewire, that could be a very interesting addition to the market if they decide to go forward with it. Looking forward to seeing how this develops. Unlike many of the near-silent electric two-wheelers, this one has a sound much like a jet turbine spinning up (kind of remind me of my old Saab 900 Turbo). If you like the possibilities here, talk to your local Harley Davidson dealer and express interest.

New Energy Strategy for Minnesota Evaluates Renewables

A new article in the RMI Outlet looks at a comprehensive evaluation in Minnesota to assess the value and potential of renewable energy resources to replace the infrastructure heavily dependent on fossil fuels. The move has elicited some corresponding excitement from businesses in the state.

And it is not just Minnesota’s government building momentum around an alternative energy future. The state’s Fortune 100 companies, such as Target and Best Buy, have set significant GHG reduction goals. Its power companies continue to expand renewable generation, including both solar and wind. And Minnesota’s civil society, pillared by organizations such as Great Plains Institute and Center for Energy and Environment, helps facilitate change and drive innovation in the energy and efficiency sector. That is why RMI was excited to support the Minnesota Department of Commerce in the development of a comprehensive guide to conducting an energy future study for Minnesota.

You can imagine that somewhere in the faraway, fictional land of Lake Wobegon, solar panels are appearing atop barn roofs and wind turbines are gracing ridge lines.

Energy Solutions—Amory Lovins Speaks at Bioneers

The annual Bioneers conference is often a revelation to attendees, offering fresh, pragmatic, sustainable solutions to the social, cultural, and environmental problems of our age. The last conference included a keynote address from Amory Lovins, the cofounder, chief scientist, and chairman emeritus of the Rocky Mountain Institute. It's worth viewing—the talk summarizes many of the key ideas of Reinventing Fire, Bold Business Solutions for the New Energy Era.



Watch for a YouTube posting of Lovins' talk at TED2014: The Next Chapter, to be held in Vancouver, BC, Canada this next week.

Brighter Streetlights, Less Energy

As reported by the Earth Island Journal, a shift from traditional streetlights to light-emitting diodes bulbs is being instituted by cities in locales around the country, from San Antonio to San Francisco. 

Energy savings from this conversion are already showing benefits. Quoting from the article:

In terms of the environment, LEDs definitely bring some benefits, the biggest of which is energy savings. The Oakland Streetlight Conversion Project will save the city nearly $20,000 per year in energy costs, and will reduce city greenhouse gas emissions by approximately 40 percent (or 80,000 pounds) per year. “The overall goal of this whole project was to have better light in our city streets,” says Kristine Shaff, a public information officer with the City of Oakland. “And the energy savings are tremendous.”

One catch, noted in the article, blue-rich LEDs have the potential to disrupt circadian rhythms in animals and humans, so municipalities are encouraged to install yellow-rich LEDs to eliminate the concern.

Solar Panels Sound Death Knell for U.S. Utilities

Energy supply and demand has been the dominating mechanism controlling prices in the public utility sector for a century and that model is threatened by the rise in solar power and other distributed renewable energy technologies, writes David Roberts in this Grist article. Reducing energy demand and improving energy efficiency are anathema to the utilities, by their own admission, as Roberts explains. 

The "money quote" in the article, taken from an Edison Energy Institute (EEI) report, states: 

The financial implications of these threats are fairly evident. Start with the increased cost of supporting a network capable of managing and integrating distributed generation sources. Next, under most rate structures, add the decline in revenues attributed to revenues lost from sales foregone. These forces lead to increased revenues required from remaining customers … and sought through rate increases. The result of higher electricity prices and competitive threats will encourage a higher rate of DER additions, or will promote greater use of efficiency or demand-side solutions. 

Increased uncertainty and risk will not be welcomed by investors, who will seek a higher return on investment and force defensive-minded investors to reduce exposure to the sector. These competitive and financial risks would likely erode credit quality. The decline in credit quality will lead to a higher cost of capital, putting further pressure on customer rates. Ultimately, capital availability will be reduced, and this will affect future investment plans. The cycle of decline has been previously witnessed in technology-disrupted sectors (such as telecommunications) and other deregulated industries (airlines). 

The bottom line is: don't expect the public utilities to be leaders in the shift to renewable energy. It's clearly not in their financial interests to do so.

A Community Breaks Away from Coal

Dissatisfied with the direction of the utility company supplying their energy, citizens of Boulder, CO took matters into their own hands and passed ballot measures to create their own municipal power utility. As written in Yes Magazine:

The city’s current electricity supplier, Xcel Energy, is a large corporation that sources more than 60 percent of its power from coal. Colorado climate activists tried for years to persuade Xcel to transition from coal to renewables, arguing that the state’s plains, mountains, and 300 days of annual sunshine give it abundant potential for the development of wind and solar power. But they found Xcel’s take-up of renewables was frustratingly slow. Xcel is investing $400 million in its coal-powered plants, and its plans for renewables stops at just 30 percent in 2020, with no further increase until 2028.

If more communities follow this example, we might even become effective tackling global warming while demonstrating the power of genuine democracy in action.

 

Go fast without gas

Humans have a lot of different ways to get from Point A to Point B on this planet, but only the velomobile lets you travel with the grace and whimsy of a cartoon character. 

As profiled in Grist, the velomobile consists of a reclining bicycle protected by a fiberglass shell that can optionally be assisted by an electric motor. They're fast, fuel free, and worth consideration if you're tired of being a victim of the fossilized proponents of the fossil fuel industry.

Get out there and pedal!

Almost as smart as termites

We know that ground-nesting termites can build mounds where the temperature and humidity remain moderate year round (a concept that has drawn the attention of architects in recent years). But, for whatever reason, humans don't typically pay much attention to natural heating and cooling in their building design and construction—a fact that leads to an enormous amount of energy consumption so that building inhabitants don't suffer from the heat or cold.

You can find exceptions to this tendency to ignore trees, shade, hillsides, and sun exposure when constructing buildings, even back in the 19th century. One good example, highlighted in Julia Whitty's Blue Marble blog (the post is a couple of years old, but as relevant today as when it was written), is Lincoln's cottage, where the President escaped the suffocating climate of Washington D.C. in the summer.

Among the passive techniques that characterize the cottage:

The builders relied on smarts not watts. Some of their techniques included:

Orienting the building so a powerful crossbreeze blows when the front door and rear windows are opened

Installing tall windows with two sections, a top half to expel warm air and a bottom half to introduce it

Attaching shutters to block the sun or let light in when necessary
Decorating with lace curtains to minimize bugs not breezes

Some of the simplest techniques available could make an enormous difference in energy consumption in our homes and cities. It's not too late to learn from the termites and the builders of the 19th century.

Irrational Disdain for Electric Vehicles

The mainstream media holds sway over much of public opinion and messages repeated over and over seem to become the reigning paradigm, engrained deeply into most everyone's consciousness. As Steve Harvey points out in The EV-haters guide to hating electric cars, the list of fallacies that are promoted in this way is long and continuous. An example Harvey provides is the typical EV-hater calling electric vehicles a sales flop despite one- and two-year waiting lists for most models.

To counter the many misconceptions, Harvey compiled a list of "truthy" facts and introduced it in this way:

Whatever the reason, the media often has an irrational disdain for electric vehicles. And a similar disdain is common among the general population too. The same EV-hating arguments are repeated ad nauseam in the media. After analyzing the key arguments of the EV haters, I have compiled what I believe is the first-ever "EV-Hater's Guide to Hating Electric Cars." If you really hate EVs -- and you know who you are -- then this Top 10 guide is especially for you.

Good information to have on hand the next time you get into an argument with an EV-hater.

Solar-powered aircraft spends 12 hours aloft, consumes no fuel

It only flies at 30 mph, but what it lacks in speed it makes up in efficiency. This aircraft from Solar Impulse, designed to demonstrate the potential of renewable energy, stayed aloft for 12 hours 59 minutes without consuming a single drop of avgas. This article by Gizmag notes:

Solar Impulse is an astonishing feat of engineering. It has a wingspan of over 200 feet (61 m) yet it weighs only 1600 kg (3,527 lb) and carries almost 12,000 solar cells which supply all of the energy required to keep it aloft.

The following video shows this amazing aircraft during the final leg of its historic voyage.

Three-wheeled ZAP Alias classified as a motorcycle

Federal certification for the ZAP Alias was simplified by the three-wheel design, which means that it only had to meet certification standards for a motorcycle rather than more stringent automobile requirements. ZAP, headquartered in Santa Rosa, CA, recently acquired a majority share in Zhejiang Jonway Automobile Co. Ltd. in China, where the Alias will be manufactured. The first deliveries of the electric vehicle, priced at $38,000, are slated for September 2011.

Houston embraces renewable energy

Houston serves as an excellent model for moving away from fossil fuels and nuclear power to a genuinely clean, infinitely renewable approach to meeting a major city's energy needs.

Smart meters encounter resistance in CA

Smarten up, people, urges a post in The TerraPass Footprint. Numerous consumers are balking at the smart meter installations the California utility, PG&E, is rolling out across the state. Privacy and electromagnetic sensitivity are two of the issues being cited by consumers. If a significant proportion of utility customers choose to opt-out, the value of the entire program—which can provide useful minute-by-minute information about electricity usage—can be significantly lessened.

The post's author, Erik Blachford, comments:

For those who aren’t familiar with the smart meters, the basic idea is to replace analog meters read by hand (er, by eye), with digital meters which transmit electricity usage information wirelessly and presumably more accurately back to the utility. This technology enables but does not automatically trigger a variety of new rate-setting possibilities, most notably time-of-day pricing. By the same token, it enables the utility to provide consumers with more detailed information about their energy use; this data can be helpful for consumers hoping to reduce their consumption or even just their bills (though there are other services which don’t involve smart meters which achieve some of the same goals). Finally, smart meters may eventually tie back into the smart grid, allowing utilities to manage power distribution better by optimizing power available from small, distributed energy sources.

The trade-off between individual rights and the greater good of the commons (through a more efficient energy distribution network that can accommodate micropower installations more easily) is a tough one. In this case, the greater good may be on the side of smart metering.

A city powered by waste

Kristianstad, Sweden is setting an example for the rest of the world, as highlighted in this NY Times article, Using Waste, Swedish City Cuts Its Fossil Fuel Use. After a ten-year effort, the city of 80,000 has cut off the use of oil, natural gas, and coal for heating and now relies on waste products from farming and food processing to generate biogas.

hulking 10-year-old plant on the outskirts of Kristianstad uses a biological process to transform the detritus into biogas, a form of methane. That gas is burned to create heat and electricity, or is refined as a fuel for cars.

Once the city fathers got into the habit of harnessing power locally, they saw fuel everywhere: Kristianstad also burns gas emanating from an old landfill and sewage ponds, as well as wood waste from flooring factories and tree prunings.

Though the lock on fossil fuel use in the U.S. appears to be unbreakable, sometimes workable solutions to our energy problems are right in front of our noses.

Triac is not Tesla, but it's not meant to be

Tesla may have the celebrity cachet and media spotlight, but the humble, three-wheeled Triac is clearly the more practical choice for a "Green Core" consumer looking for a $25,000, all-electric vehicle with an honest 100-mile range. In a siliconvalley.com article, Mike Ryan, president of the firm based in Salinas, CA that produces the Triac, says that the car is aimed at people who have a more environmentally conscious lifestyle.

Key among the features is a sophisticated system for predicting remaining range before a recharge is needed.

The Triac will include a Vehicle Efficiency Data Assistant -- VEDA -- interface to the battery management system as well as diagnostic and navigational data. VEDA is an electronic learning system that captures a person's driving habits and commute patterns to accurately predict miles left before recharging.

"Range anxiety is something that gives people a lot of concern," Ryan said. "Say I forgot to charge my car. I'm at lunch. I want to run an errand before I go home. Will I make it home?"

Options in the electric car market are getting more expansive. The Triac is an interesting home-grown option that favors practicality over panache—and for many buyers that's a plus.

Solar power creates electric grid challenges in Germany

The accelerating adoption of solar panels in Germany looks like a case of too much of a good thing. The antiquated power grid across the country is having trouble coping with the fluctuations resulting from feed-ins from photovoltaic systems and wind turbines.

As reported in this UPI.com news story:

Experts have long called for an overhaul of the European power grid to integrate the fluctuating renewable energy sources such as solar and wind power.

Experts forecast between 8 gigawatts and 10 GW of solar power capacity to be installed this year -- the equivalent of roughly 10 large coal-fired power plants. In 2009, only 4 GW were installed.

With an equally fragmented and outdated power grid, the U.S. would do well to overhaul its own infrastructure in preparation for more extensive use of renewable energy. Google's investment in the Atlantic Wind Connection is a step in the right direction.

Mini Goes Electric

Another automobile manufacturer, Mini, dips its cast aluminum toe into the electric vehicle market, but this type it's scooter prototypes that appeared at the Paris Motor Show, rather than cars, as profiled by Wired magazine.

Details are scarce. It has an electric motor. You plug it in. But, the prototypes recall classic Italian scooters and Mods versus Rockers schtick.

There are three “interpretations” of the design by Adrian van Hooydonk, senior VP of design for BMW Group. One is a two-seater done up in the same colors (matte charcoal and yellow) as the Mini-E electric prototype. The second is a single-seater Mini calls “almost purist in design.” The third draws on British ’60s pop culture, particularly “the distinctive graphics of the Mod era.”

As a Mini Cooper owner and an admirer of the technology emerging from this BMW Group, it will be interesting to see how this plays out.

Real-world road test: life with a plug-in Prius

Adam Vaughan puts the new plug-in Prius through its paces in London and its outskirts and discovers that the vehicle is reasonably practical. But clearly more charging points are needed for this type of vehicle. Even in the mighty metropolis of London there are far too few.

Plugged in via the leads in the boot, the electric battery was topped up for free in an hour and a half. While Westfield’s developers deserve credit for installing the points in the first place, they also warrant a raspberry for allowing any car to take the charging spaces – they’re not reserved for electric vehicles.

And here lies the only real drawback to PHEVs: there are not enough places to charge them, even in the urban areas where they’re best-suited. Home-charging, in particular, is tricky in cities because of the lack of driveways and garages. Of course, because you have petrol as a backup, you don’t have to panic about recharging as you would with a 100% electric vehicle. But by not being able to charge out and about, you lose the unique environmental and financial benefits.

It's promising technology if we find smarter ways of generating the energy supplied to the charging points, but that's another problem for another day.

Kia set to introduce electric vehicle

The Kia Electric POP (highlighted by Fast Company) hints at the future of electric vehicle design. The tiny three-seater will be on display in October at the Paris auto show. Bring sun glasses.

String rail: a low-cost rail alternative?

String rail, a promising, inexpensive alternative to conventional rail systems profiled by Gizmag, might be a genuine breakthrough in comparion with other forms of high-speed mass transit. With costs estimated to be anywhere from three to 10 less expensive than approaches such as railway or monorail, string rail—originally prototyped by Anatoly Unitsky in Russia—is projected to support top speeds of 220 to 300 mph.

Is this something that could actually happen? The article's author, Loz Blain, notes:

Would I find it a bit freaky to be doing 350 kmh while hanging from a wire? Yes sir. Am I entirely convinced that the strings won't snap, even if a tower or three get taken out? No. Would a full scale demonstration convince me? Probably, yes. And this is the stage Unitsky is stuck at. His demonstration rig is small-scale, and there's nothing like the UST in operation anywhere in the world.

STU Systems in Australia is working to commercialize the concept and, naturally, seeking investors. Does anyone have a few hundred million of seed money to help get a very interesting mass transit approach off the ground?
