Power Storage Advances from Unexpected Sources: Renewable Energy Storage Kicked Into High Gear

James Cahalin | Jun 02, 2011

What do you think has a greater impact on society, a Bugatti Veyron Super Sport or a Tesla Roadster? Both have spectacular performance reviews, with the Super Sport setting top speed records. Both will turn heads driving down any road or even through any parking lot in the world. Both are truly engineering marvels.

However, the engineering accomplishments behind both vehicles will be dwarfed by the advances Tesla has made with its power storage devices. Let’s take a look at a few numbers for both vehicles (see table).

These numbers are astonishing. As a “car guy,” the opportunity to drive either of these vehicles would be amazing. However, as an energy professional, these numbers are even more astonishing.

Amazing Head Output

The Bugatti Veyron Super Sport was designed and built for one purpose — to set a new speed record. It is also what I like to refer to as a “straight-line car.” What I mean by that is simple: Even with that much horsepower and amazing technological advances, there are cars (and some cost under $100,000) that can beat the Super Sport around a race track.

Off Grid Living-You Can Do It Too

January 21, 2009

More and more people are realizing that you can still enjoy modern amenities while enjoying the independence of off grid living.  Being off the grid means being exactly that, off the grid.  No power lines, no electric bills, and being free of utility grid demands, not to mention their ever-rising rates.  Off grid living is environmentally friendly and cost effective and it is an option available to almost any one owning a home.

The principles of off grid living may be applied to any home in the world, even those currently tied to the grid.  From solar panels, hydro power and windmills, there is growing curiosity in off grid living and breaking free from fossil fuel burning power plants.  The technologies have advanced and the costs have dropped greatly.
Even do-it-yourselfers can take leaps into off grid living with many kits, resources and manuals available for instruction.  As energy demands increase globally, those living off grid can rest easy knowing their own energy costs are diminishing.

The idea of off grid living can be scary to some who believe they will have to give up some of their most prized possessions and electronic gadgets to achieve such freedom.  This is very far from the truth.  Off grid living is simply about learning to moderate your use of electricity.  It can be as simple as turning off lights that are not really in use.  Purchasing appliances that don’t use energy when not in use (like clocks on microwaves and stoves).  Learning to unplug, not just turn off.  Things like computers and printers, well anything with the little green light that is always on, these items are stealing precious energy and adding to your bill.  Wanting to become part of the off grid living adventure, doesn’t always mean giving up everything, sometimes it just means getting smarter about the things you have.

How Living Off the Grid Works

by

Off-the-grid Lifestyle

You’re excited about going off the grid now, right? You’re set to get your solar panels and septic tank. You have the well driller booked and you’re ready to say no to utility bills. Before you follow through on all these moves, you need to think about the lifestyle changes that come with going off the grid.

Even with solar and wind power, you’ll still need to limit your use of electricity. Most people interested in living off the grid do so at least in part to live a greener life, so conserving power goes hand-in-hand with this decision. With adequate solar and wind systems, you should be able to operate most of your electric appliances and gadgets, but not necessarily at the same time. If you’re using a hair dryer, avoid using the microwave. If you fire up the blender, unplug your space heater. Major electricity users like washing machines should be operated at night, when your other power needs are minimal. True disciples of the back-to-land movement wouldn’t use a washer and dryer anyway. Washing clothes by hand and using a clothesline is a rustic alternative.

The same goes for your water use. With a cistern system, in periods of little rain you might need to let the dishes pile up for a couple of days or limit your toilet flushes. Some people go so far as to turn off the shower water while they lather or wash their hair. Collecting additional non-potable water in rain barrels is a great way to water plants, wash dishes and keep your pets hydrated without dipping into your well or cistern.

Energy Star appliances are the most efficient on the market and a good way to save money on your bills. Look for the yellow stickers on the appliances when you buy them and compare the ratings. In addition to saving energy, the government offers rebates on Energy Star appliances, so you’ll be saving money as well. You should­ also switch your light bulbs to the energy-saving compact fluorescent bulbs.

Building A Cob House – It is not what you think

Posted on by
Reply

When I first saw the headline of this next site, I thought: can this be? I had heard of actual corn cob houses in rural America. They are basically slatted walls filled in with corn cobs and then finished inside and out. They are sort of a variation of hay bale houses. But this is way different.

Building a Cob House

By Off Grid Ebert

In a time in which we are increasingly hearing scary statistics about the fate of our planet, the way forward in the field of sustainable, green building may just be to go backward.  This is certainly the case for people demonstrating a growing interest in building earthen homes and structures using an ancient method known as cobwork or cobbing.  Cobbing, believed to have originated in the Maghreb as early as the 11th century, spread into wide usage across many parts of the rest of Europe as the main building style for homes.  The name of this style of building comes from the word cob, which is the name of the building material itself, formed of a mixture of earth (such as clay, sand, and other soil), straw, and water.  Despite what the materials may imply, this substance, when dried, is fireproof.  It is also inexpensive, and naturally cool in the summer heat and relatively easy to heat in the winter.

Many homes built of this material centuries ago still stand and remain in use.  Pictured here to the left is a cob house in England, believed to have been built in the late 1700s. (Photo by Tim Green, http://www.flickr.com/photos/atoach/4927564858/) These homes typically have thatched roofs, while small but efficient fireplaces with chimneys provide warmth when the weather is cold.

The appearance and texture of cob varies from region to region, depending on the available natural resources and their characteristics.  As such, cob is one of the most versatile building materials on earth.  It can be molded and shaped into whatever form is framed by the builder.

Living Off The Grid Has Gotten Sexy – Thanks to Natgeo’s Preppers

Posted on by
Reply

I have only seen one episode of Preppers so I am no expert. The show did seem intrusive because many of the “preparing for catastrophe” types are really sensitive to outside interest.  Some fear laughter, others fear exposing their hoards to people who might try to take them away from them, and others are just by nature isolationists. Also many of their theories about the impending “end of the world” are just plain incoherent. Thus painful to listen too. Most the off the grid people I know are not Preppers, they are, like me, cheap. They hate giving money to the utility companies.

What is living off-grid?
by LINDAM on FEBRUARY 11, 2012 – 1 Comment in OFF-GRID 101

The literal definition of living off-grid (or offgrid or living off the grid) is living without Utility power or water or waste disposal.

It can go further than this, to include being disconnected from the infrastructures that make life convenient, including roads, banks, schooling, doctors and so on. Even the Internet is a grid of sorts. Wikipedia has an extended discussion

In the absence of Utility electricity, energy needs are often supplied by solar, water or wind energy. (more…)

Cuba Moves Ahead With Alternative Energy – Will they move ahead of the U.S.

Posted on by
Reply

As rediculous as it sounds, Cuba could very easily overtake the U.S. in its use of alternative forms of energy. Why? Because like China they have a planned economy.

http://peakoil.com/alternative-energy/cuba-on-the-road-to-clean-energy-development/

Cuba on the Road to Clean Energy Development

More than a decade ago, solar electricity changed the lives of several mountain communities in Cuba. Now this and other renewable power sources are emerging as the best options available to develop sustainable energy across the island.

“If the world’s clean energy potential exceeds our consumption needs, why do we insist on using the polluting kind?” asked Luis Bérriz, head of the Cuban Society for the Promotion of Renewable Energy Sources and Respect for the Environment (CUBASOLAR), a non- governmental organisation that promotes the use of alternative and environmentally-friendly power sources.

According to his calculations, the amount of solar radiation Cuba receives is equivalent to 50 million tonnes of oil a day.

“If we covered the 1,000-kilometre-long national highway with solar panels we would generate all the power currently used, without using fossil fuels or occupying a single square metre of agricultural land,” Bérriz said to IPS in an interview.

Moreover, “nobody can block the sun; it belongs to all of us,” he added.

Bérriz is a researcher and long-time advocate of renewable power sources who prefers to talk about “reversing” climate change – which he says is caused by “the destructive actions of today’s societies” – instead of “adapting” to it.

In his opinion, adapting to what others destroy sounds more like “conformism”. Industrialised countries are responsible for 75 percent of all anthropogenic greenhouse gas (GHG) emissions, which cause global warming. The leading GHG is carbon dioxide (CO2).

For Bérriz, the best course of action is to move from oil to clean energy sources, which exceed power needs. The way to do this is to develop the knowledge, technology and industry necessary to tap into the various renewable energy sources most available in each area, he says.

Key components of this process, Bérriz argues, are the training of scientists, technicians and skilled workers to cover human resource needs, and the creation of an energy and environmental culture that will raise the awareness essential for the development of solar power based on “fairness and solidarity”.

Fukushima Heats Up Again – Are these the reactors that refuse to go away

Posted on by
Reply

I have my doubts about what this actually means. A cold shutdown is considered to be 93 degrees Celsius or 212 degrees Fahrenheit. So the reactor is still technically cool, and I doubt if it would mean much if it went up to even 500 degree Fahrenheit because that is a factor of three below its operating temps of 2,300 degrees or the 5,500 degrees in their operation range. Still there is an “ooga booga” factor in there somewhere.

Rising temperatures trigger concern at Japan’s Fukushima nuclear plant

By Danielle Demetriou in Tokyo

3:28PM GMT 07 Feb 2012

Water temperatures at Japan’s damaged Fukushima nuclear power plant have risen more than 20 degrees Celsius over the past week.

Concerns are growing in relation to conditions at the plant, in northeast Japan, which was declared in a state of cold shutdown in December last year.

Temperatures at the bottom of the No. 2 reactor have climbed to over 70 degrees Celsius, marking a rise of more than 20 degrees since the start of February.

Boric acid has been injected into the reactor by workers of Tokyo Electric Power Company (TEPCO), operators of the plant, in order to prevent an accidental chain reaction.

The rate of cooling water injected into the unit was also increased as part of the plant workers’ attempts to stem the surge in temperatures in the reactor.

The government declared that the power plant was in a state of cold shutdown on December 16, nine months after a major earthquake and tsunami triggered a nuclear crisis.

While Consumer Reports does not like “on demand” water heaters, I do. Once you get used to them they are a blessing and if you have a large family the money you can save is amazing. But for me it is a mental thing. First in mind solar water heating should have been the way our society should have gone 100 or even 200 years ago. I mean it is there and we “throw it away”. But there is also something so bourgeoisie about heating up a bunch of water to sit in a tank wating for us to (what?) fain to use it. But if we don’t then a heater comes on and heats it up again. The whole mindset there is flawed.

http://www.tanklesswaterheaterguide.com/

Tankless Water Heaters heat water directly without the use of a storage tank. Therefore, they avoid the standby heat losses associated with storage water heaters. When a hot water tap is turned on, cold water travels through a pipe into the unit. In an electric Tankless Water Heater an electric element heats the water. In a gas-fired Tankless Water Heater a gas burner heats the water. As a result, Tankless Water Heaters deliver a constant supply of hot water. You don’t need to wait for a storage tank to fill up with enough hot water. Typically, Tankless Water Heaters provide hot water at a rate of 2 – 5 gallons (7.6 – 15.2 liters) per minute. Typically, gas-fired Tankless Water Heaters will produce higher flow rates than electric Tankless Water Heaters. Some smaller Tankless Water Heaters, however, cannot supply enough hot water for simultaneous, multiple uses in large households. For example, taking a shower and running the dishwasher at the same time can stretch a Tankless Water Heater to its limit. To overcome this problem, you can install a “whole house” type Tankless Water Heater or install two or more Tankless Water Heaters, connected in parallel for simultaneous demands of hot water. You can also install separate Tankless Water Heaters for appliances—such as a clothes washer or dishwater—that use a lot of hot water in your home.

Other applications for Tankless Water Heaters include the following:

  • Remote BBQ or outdoor sink
  • Poolhouse or pool shower
  • Remote bathrooms or hot tubs
  • To serve as a booster, eliminating long pipe runs, for solar water heating systems, dishwashers and sanitation.

Insulate Your Basement – Even in an already built home

Posted on by
2

Yes, you can get a backhoe and dig a trench around your house for relatively cheap but, it really is a waste of time. Parging the walls first pretty much means coating the walls to make sure moisture does not get behind the insulation that you are going to put up. I suggest using a modern basement epoxy of some sort and I recommend rigid insulation after you have done that. Rigid is easier to work with and you can make the whole project into an adhesive affair where you adhere the furring strips to the epoxied walls and then you adhere the foam board (or whatever) to the furring strips. Boom, you are done unless you need to paint them for someone else in the house that hates the color of the “naked” board. You know who I mean. Like the article says as far as the vapor barrier placement you have to call your local building code people cause I got no idea,

 

http://www.green-energy-efficient-homes.com/energy-efficient-basement.html

Exterior wall insulation inside the walls

Insulating outside your exterior walls is often too expensive or impractical in existing homes. You can insulate the inside of your basement walls but you may exacerbate the problems associated with moisture if you don’t do the job correctly.

Parging: If moisture is seeping into your walls, parge the masonry walls to seal any cracks and strengthen any weak or porous masonry. This will help prevent water from seeping in from outside.

Vapor barrier: Vapor barrier should be outside the insulation if you are in a hot climate and only cool your home; it should be on the inside if you are in a cold climate and are mainly heating your home. Consult your local city building permits department to find out what are the suggested or mandated insulation and vapor barrier configurations for energy efficient basements in your area.

Framing: If possible, leave a gap between your framing and the exterior walls, to prevent moisture from the masonry from causing wood rot in your framing. Use small spacers behind 2×3 studs, rather than 2×4 studs against the outside wall, and you’ll still have room to install the standard insulation for 2×4, 16-inch-stud construction.

Insulation: If there is any likelihood of moisture getting into your basement, use a rigid foam insulation rather than batt or other fiber-based insulation. Moisture seeping through exterior walls will dampen the insulation and reduce its R value significantly within a few years, so you’ll start with an energy efficient basement and in a few years be losing as much heat to outside as before the renovation. Moisture will not have much effect on the R value of foam insulation. Buy the highest R value insulation you can – you can get an R value of 6 per inch in some insulating foam sheets. If you want both insulation and waterproofing, you could consider having Icynene insulation applied to exterior walls after framing but before drywall is installed.

Other places you should insulate

A couple of other important things to consider about basement insulation:

  • In an older house, where a shower stall is already installed against an outside wall, check the insulation level behind the shower. A prior owner or contractor may have installed the shower without adequate insulation. If you are remodelling or can access the wall space behind it, inject foam insulation or otherwise upgrade the insulation. You’ll have more comfortable showers and you’ll cut down on overall heat loss.
  • Insulate the perimeter of your basement ceiling (an area called the ‘rim joists’), from the outside walls to about 16″ to 24″ from the outside walls, to prevent moisture from creeping in between the upstairs

Blown Insulation – My pick for retrofits

Posted on by
Reply

It is a pain in the behind to cut blow holes in walls to blow in insulation. It is also tricky to work around windows and other internal factors like headers and footers,but if you are not tearing out the interior walls and are environmentally concerned, I still think it is the best bet. Here is a great article about it.

http://www.aboutsavingheat.com/cellulose.html

Fill your Walls & Ceilings, Not our Landfills!
We use blown-in cellulose for most of our insulation jobs, (except for crawl spaces, where moisture and the lack of hollow walls won’t allow it.) Blown cellulose is less expensive, safer to you as well as the environment and more effective and energy efficient than its leading competitor – fiberglass.

Cellulose fills walls and ceilings and stops air infiltration better!
The fibers of cellulose insulation are much finer than fiberglass. When cellulose is blown or dense-packed into your walls and ceilings, it takes on almost liquid-like properties that let it flow into cavities and around obstructions to completely fill walls and seal every crack and seam. No fiberglass or rock wool material duplicates this action. Liquid-applied foam plastics do, but they cost much more than cellulose.

In new construction cellulose insulation can be installed in walls using a spray process or several different dense-pack dry techniques that are also effective at sealing homes against air infiltration.

Cellulose is a naturally recycled product…

Cellulose insulation is made from recycled wood fiber, primarily newspaper. One hundred pounds of cellulose insulation contains 80 to 85 pounds of recycled newsprint. The remainder is made up of Borax and Boric acid, both non-toxic fire retardants.

Today more and more communities are addressing the challenge of waste disposal through “curbside recycling” and similar conservation programs. These efforts work only if there is demand for recycled products.

The federal government is attempting to create demand through such measures as the Environmental Protection Agency’s comprehensive procurement guideline for products containing recovered materials. Cellulose unquestionably meets all requirements for insulation specified by the guideline.

When you choose cellulose insulation you help solve the waste disposal problem and help fight air pollution. This may help your community hold down taxes or refuse disposal charges. It certainly contributes to a cleaner environment.

Paper that is not recycled ends up in landfills, where it may contribute to environmental pollution, or at incinerators where energy is wasted reducing it to ashes, soot, and smoke.

…And a responsible use of resources
Even if waste paper did not create a disposal problem, most people believe we have an obligation to make maximum use of the resources we consume.

Cellulose insulation does not “save trees,” but it makes maximum use of the trees we have already harvested.
