Truck stop electrification is boosting fuel efficiency and minimizing dependence on foreign oil from idling trucks

There are 1.3 million long-haul diesel trucks with sleeper cabs in the United States, with most drivers averaging over 100,000 miles annually. These trucks are highly affected by skyrocketing fuel prices and are dependent on foreign oil. As the value of the dollar diminishes, transportation costs are partly to blame.

Idling Trucks Waste Fuel

Truck drivers are required to rest for 10 hours for every 11 hours of driving. A large amount of fuel is consumed when drivers leave trucks idling to maintain comfort. 85% of the energy is wasted sleeper cabs are heated by an idling truck. It is even more inefficient to cool the sleeper cab, wasting 94% of the fuel’s energy.

Having spent a lot of time in the wireless industry and being hopelessly addicted to my Blackberry and my Helio Ocean, I wanted to take a look at how manufacturers and carriers stand up when it comes to enviro-friendly action.

Nokia: Remaking Mobile
Nokia is one of my favorite handset manufacturers. Not only do they have some amazing concept devices, such as the Nokia Remade, a handset made entirely of pre-used parts from old tires to aluminum cans, they also currently have working devices on the market that are reducing impact. With covers made of recycled material and chargers that are Energy Star compliant and then some, Nokia is making bold strides in the right direction.

The 3110 Evolve’s biocover is made with 50% renewable material, and the packaging has been reduced by 60% for the handset. Along the a charger that uses 94% less energy that Energy Star compliance requires. Read the rest of this entry »

“Negawatts”, a termed coined by Amory Lovins in 1989 to describe savings created by using less energy, are becoming a reality. The fact that saving energy is much cheaper than building new power generation capacity has motivated the markets to create financial and other incentives to monetize that savings. According to an article in Renewable Energy World, several market mechanisms have emerged:

• Demand response: enrolling large users of energy in programs to lower their usage in return for compensation, which helps take pressure off the grid. Examples of demand response networks include Comverge and Gridpoint.
• White Tags: businesses earn energy savings certificates for the energy they send back to the grid based on efficiency measures they put in place. White Tags can then be sold or put toward achieving mandatory emission goals.

The potential of energy savings is largely untapped, but there is plenty of precedent for it in California. “Since the 1970s, California, through the California Public Utilities Commission (CPUC), has worked with utilities to encourage conservation rather than consumption. As a result, Californians now use about half as much electricity as other Americans.” –Glenn Croston, Renewable Energy World.

I cover a lot of upcoming or future technology, but it’s time to step into the present and aim for the past. Today we’re going to look at a technology available right now that can make some wanton energy waste history. It’s a surge protector that stakes the hearts of vampire electronics without hassling you, the sleeping victim.

Vampire appliances are pretty much anything you can plug in that still sucks energy when it’s supposedly turned off. Some are pretty obvious - the clocks on your microwave or VCR/DVD player burn all day, everyday. We know they’re not “off” because we cans see their LEDs glow. But other electronics, from your television to your cell phone charger also draw power when they’re plugged in but not in use. Check out a handy graph from Good Magazine. Some gadgets are notorious, like your plasma TV. Estimates claim that 5% or more of U.S. energy usage is insidiously wasted by “stand-by mode” or certain misleading “off” buttons. A whopping 5% may not sound like much, but it adds up to about $1 Billion dollars per year - and energy prices will probably continue to rise.

Be honest - how many times would you go around the house unplugging everything before it got old? Smart greenies have been switching off their surge protectors, but it’s easy to forget while watching your favorite late-night TV show or blogging at 4am. So what can we do about these metal-toothed Nosferatu in our midst? How about a surge protector that turns off all your appliances for you? Read the rest of this entry »

It is often said that the so-called ‘low hanging fruit’ in the energy puzzle is not wind, solar, biomass, geothermal, or any of the other renewable resources. The cheapest way to create more available energy is to use our current capacity more efficiently. In other words the ‘low-hanging fruit’ is energy efficiency.

I was reminded of this fact recently when I read an interview with the king of all energy geeks, Amory Lovins, at Mother Jones. Lovins was asked the question, “If you had $1 million to invest in the energy sector, where would you put it?” Lovins responded,

“Efficient use. I want to do the cheapest things first to get the most climate protection and other benefits per dollar. Buying micropower and “negawatts” instead of nuclear gives you about 2 to 11 times more carbon reduction per dollar, and you get it much faster.”

While not as ’sexy’ as solar and wind, energy efficiency might be the smartest investment play if you’ve got some cash burning a hole in your pocket (though that’s not really the current trend). And while we here at CleanTechnica do not really fancy ourselves to be professional analysts of Jim Cramer or Tom Konrad caliber, we do keep our eyes on emerging trends in the industry. For that reason it is hard not to pick some favorites. I’d like to share two of my favorite energy efficiency plays with you: Echelon (ELON) and Beacon Power (BCON) . Read the rest of this entry »

Happy Earth Day to all!

This Earth Day let’s break it all down and see things for what they are.

Our world is in a state of climate chaos as a result of our conveniences. This CleanTechnica blog is an opportunity to see what is being done worldwide in the realm of clean technology (ie. renewable energy, alternative fuels, sustainable products and services etc…) so that we can keep these conveniences.

That’s terrific–I’m glad it is being done, but this Earth Day I’d like to say–F your conveniences!

Here are 22 (since it’s April 22nd) things you can do daily that are inconvenient but we would all benefit greatly if everyone did them. And, to be honest–they’re not that inconvenient. They may in fact be just inconvenient enough that when you do them you get the rewarding feeling that you are doing something to benefit the greater good (i.e. earth, and its many earthlings) besides simply donating to a charity once a year during the holiday season.

I know we live in a country full of citizens more excited that Starbucks has a drive-thru than Toyota has a Prius, and will not be truly satisfied until Starbucks has a video camera mounted a mile from its store so it can read your license plate to anticipate your arrival and have your drink ready for you by the time you get there. Then all you’d have to do is slow down enough for the “barista” to throw your “coffee” into your car as you rolled by with your window down. After all, complete stops are for suckers! I digress…

Those people are out there in large numbers–and they are probably not reading this blog, so it’s up to you to send it to them because these 22 inconveniences can change the world.

Not long ago I was visiting my old hometown of Chicago, walking through the streets of Bucktown on my way to my favorite bar (Map Room) when I noticed a cool house on Milwaukee Avenue near Hoyne. This “cool” house had a garden and two wind turbines on the roof (if I had the dough I would purchase two as well–leave ‘em alone on the roof and hope they’ll procreate!). I slowed my gait to check the place out. I sought no more info, as I was excited to get to Map Room.

This weekend, a few months after my trip to Chicago, I was returning some books to my local library. They have a “free magazine” rack near the door so I stopped and grabbed a gardening magazine and a few National Geographics from 2007. When I got home I began flipping through the October 2007 National Geographic which highlights the pros and cons of ethanol (for more read this post from Gas 2.0), and there on the page right after the table of contents was an Ameriprise Financial article about the place I walked past in Bucktown a few months earlier. It is the home of Frank and Lisa Mauceri and their record company Smog Veil Records.

When generating electricity, roughly two-thirds of the energy is lost. Heat is created as a byproduct to spin turbines and later wastes away in cooling towers. Chicago has committed to produce 1.5 billion kilowatt hours of electricity by 2010 with a process call combined heat and power or cogeneration, which finds use for the generated heat. This process can be over 90% efficient.

Excess heat can be used for dehumidification, heating water, and process heat. In an ideal world, the electricity and heating loads for the given application are similar. Hospitals, prisons, paper mills, oil refineries, waste water treatment centers, and even large towns can be good candidates for this technology. Your car can even be an example, with waste heat from the engine being used to warm the interior.

Let me be the first to confess: I love my laptop. I spend more time with it than most people in my life, including family, room mates, and boyfriend. I might even go so far as to admit an unhealthy infatuation with the Internet, writing, and a handful of computer games. Yet as an aspiring environmentalist, my electronic sidekick poses an uneasy paradox. How do I lay claim to “green” (whatever that really means) when I spend so much of my time plugged in?

Computers aren’t very environmentally friendly. They contain lead, mercury, cadmium, lots of plastic, and they thirst for electricity. Most people don’t realize that most of a computer can be recycled, so most discarded computers head to the landfill where the heavy metals can contaminate local water and air. Computers and electronics have become disposable in our culture, so the amount of electronic waste generated each year is astounding. Fortunately these are not problems without solutions. Starting from the beginning of a computer’s life to its demise, it can be easy to optimize everything about your PC.

Buying, Building, and Design

With the new popularity of green, critics have been quick to turn on companies like Apple for pumping out so many gadgets. The good news is that companies have been quick to respond with energy-efficient models, recycling programs, and improved design. Many “green” initiatives focus on energy efficiency but ignore manufacturing or end-life issues, so be wary of their “environmental” credentials. If you find a product or company that can vouch for the creation, use, and disposal of their products, you’ve struck gold. The good news is that newer models use fewer harmful chemicals and metals, require less energy, and improve performance. Lean, and mean is the angle many companies are aiming for with “green” patched on to sell. Laptops are the best example of this trend as they become smaller and more powerful simultaneously. So rest easy knowing that if you must buy a new computer, it will probably be more efficient than your old one… assuming you don’t hook a brand new 60-inch flat screen to it.

Today’s Chicago Tribune made a big fuss about a new water-cooled supercomputer at the University of Illinois. Yes, it will do massively more research, and yes, it will help researchers solve even more problems. But what really seems newsworthy, and which the reporter left to the last line of the article, is that the new IBM HydroCluster will use 40% less energy and 80% fewer air conditioners than air-cooled computers.
