"Civilization as we know it is coming to an end soon. This is not the wacky proclamation of a doomsday cult, apocalypse bible prophecy sect, or conspiracy theory society. Rather, it is the scientific conclusion of the best paid, most widely-respected geologists, physicists,bankers, and investors in the world. These are rational, professional, conservative individuals who are absolutely terrified by a phenomenon known as global "Peak Oil."
Don't tell anyone but late at night instead syphoning gas. I use thick wires and I steal electricity from electric cars.
I once drove from San Diego to Los Angeles in my electric car and used only $1.09 worth of electricity. The drawback, however, is that the extension cord cost $17,632.

The Department of Energy announced today that Energy Secretary Steven Chu will travel to India and China from Thursday, November 12 to Wednesday, November 18 as part of the Department’s efforts to advance opportunities for international clean energy cooperation.
Iran is trying to go nuclear but we wouldn’t allowed, we only talking reduction and reduction of green house gases, that is more taxes to consumers what about tax breaks or incentives, for planting trees or shrubs or even grass around your house what about free solar cells on your roof how about that. If the green house agenda means more money out of my pocket and into the government pocket then it’s a bs another way to make money for the government. When do I get some money back.
I so want to go Solar. The plan is for china to make it on the cheap over there and then bring it here to sell. Seems transporting it would be pretty costly. We keep trying to cut back on electric and the rates keep climbing, it's a no win...unless we go solar and escape the old ways. I am at a point where I feel like buying as many panels as I can and hiring a savy climer to put them all on the roof...I am trying to learn from the solar videos on youtube. We should start local solar clubs to help eachother. I may try that after the new year... put up a notice at the local library.
Lithium-ion battery maker Electrovaya Inc. may finally be turning a slew of promising partnerships and MOUs over the past two years into more than just words. The Mississauga-based company ended 2009 on a positive note, announcing in its year-end results that revenue jumped roughly 50 per cent and losses shrunk from over $4 million to less than $600,000. "Fiscal 2009 marked a turning point for Electrovaya," said chief executive Sankar Das Gupta in a statement. "Over the course of the past year we have increased our presence in the global market for lithium ion batteries used for electrification of vehicles and for smart grid applications." He emphasized that Electrovaya, for the first time, showed a profit in its most recent quarter 0f $549,000, what Das Gupta hailed as a "significant achievement."

"The measures proposed ... will be more burdensome than any of those placed on our industry throughout the United States," Chesapeake said in public comments made available to Reuters on Tuesday.
As a result, "some operators may elect to focus their risk capital in other states," the company said, which would mean New York would lose potential tax revenue from gas production at a time when the state is looking to close a $3.2 billion budget deficit.
UPDATE 3-Chesapeake says NY could drive away gas drillers
Chesapeake Energy (CHK.N) has called proposed New York state regulations for the shale gas drilling industry
unnecessarily onerous and likely to scare energy companies out of state, depriving New York of badly needed revenue.
The sentiment was supported by competitor Fortuna Energy, a subsidiary of Canada's Talisman Energy (TLM.TO), which said it was shifting its focus to Pennsylvania because uncertainties in New York threatened to undermine its investments there.

China Ends U.S.'s Reign as Largest Auto Market (Update2)
By Bloomberg News
...China’s vehicle ownership climbed to 51 million by the end of 2008 from 1 million in 1977. Per capital disposable income for Chinese households increased 46-fold in nominal terms during the period, also making the country the world’s biggest markets for products such as cell phones, beer and microwave ovens.

Green building in 2010: 10 trends to watch
by Sean Penrith
While we know the building industry had a rough year in 2009, portions of the sector avoided the doldrums. Green building was a bright spot in an otherwise lackluster year, and the Oregon design and building communities have been at the forefront.
So, what can we expect to see in the coming year in green building? Here are our picks for the emerging trends of 2010, in no particular order.
The smart grid and connected home. ..............................................................
While utilities will continue to make upgrades to the grid for more effective generation, storage and distribution of power, the big news is in the home. The development of custom and web-based display panels that show real-time home energy use, and even real-time energy use broken out by individual appliance, will go a long way toward helping change homeowners’ energy behavior and drive energy conservation.
Energy labeling for homes and office buildings. ........................................................................................
The advent of more accurate energy rating systems for homes and office spaces — similar to the miles-per-gallon sticker on your car — has caught the attention of energy agencies and legislators around the country. Not only can it make a building-to-building or home-to-home comparison easier, but a publicly available score on the multiple listing service could galvanize owners to make needed energy improvements while adding value to their building.
Building information modeling (BIM) software. .............................................................................................
The continued evolution of CAD software for building design has produced new add-on tools with increasingly accurate algorithms for energy modeling as well as embedded energy properties for many materials and features. This will prove instrumental in predicting building performance. BIM developers will soon be offering more affordable packages aimed at smaller architecture firms and individual builders.
Financial community buy-in to green building. .......................................................................................
Lenders and insurers have come to see green homes and buildings as better for their bottom line and are working to get new reduced-rate loan products, insurance packages, and metrics into place. Lenders and insurers are realizing green building owners are more responsible, place higher value on maintenance and lower operating costs, and are less likely to default.
"Rightsizing" of homes. .............................................
A larger home no longer translates into greater equity. Given that the forecast for home valuation remains conservative, that energy prices are expected to rise over time, and the Federal Reserve is expected to raise interest rates mid-year, homeowners will likely feel more comfortable building smaller homes and smaller add-ons.
Eco-districts. ..........................
Portland is already on the bandwagon with this one, encouraging the creation of greener communities where residents have access to most services and supplies within walking or biking distance. The creation of walkable, low-impact communities in the suburban setting is also gaining steam.
Water conservation. .......................................
Because indoor and outdoor residential water use accounts for more than half of the publicly supplied water in the United States, the EPA finalized the voluntary WaterSense specification for new homes in December, which reduces water use by about 20 percent compared to a conventional new home. Water will be the essential resource in the next decade.
With buildings contributing roughly half the carbon emissions in the environment, the progressive elements in the building industry are looking at ways to document, measure and reduce greenhouse gas creation in building materials and processes. This effort will be heightened once a federal cap-and-trade mechanism is launched in this country.
Net Zero Buildings. ......................................
A net zero building is a building that generates more energy than it uses over the course of a year, as a result of relatively small size, extreme efficiencies and onsite renewable energy sources. While the Architecture 2030 Challenge sets forth net zero as the goal for all new buildings by 2030, we are already within striking distance on energy efficiency know-how.
Sustainable building education. ...........................................................
The continued demand for greener buildings, especially in progressive cities, will supply new learning opportunities, not just for designers and builders but for the entire chain of professionals involved in the building industry, from real estate to finance to insurance.
We can go for getting off mideast oil... and cleaner air .............................................................................................................

This is not as complex as it might seem. And despite many commentaries a few layman clear solutions are available and being pursued by by companies in Silicon Valley.
Beginning with the more down to earth one- a pure solar energy car powered by a special fiber which can be mounted in a square to two square foot weather protected zone o the roof of a car (except in West Virginia). Here we have only a few sunshine days a year and tje use pf Sun cars would not work that well. However, the installation of wind mill structures as an alternate to the spoiling of scenic beauty of mountain tops ravaged and replanted with astro truf mold for our lost creatures to try and buld a home in a thin inch layer of gum or climb a one foot tree does present a challenge.
One major start of any intelligent plant for the new hybrid generation is to build in the U.S.A. and hire American's. The biggest problem to lowering the dependency on OPEC is no one in high finance has any intention of doing so. And in additioin the heavy special inerest lobbeying in conbress will successfully block this as well as term limits for 20 yaars.
Australia would be the key testing ground and implementation of not only sun power but the creation of massive volumes of water to convert the Aussie outback into a thriving new epicenter completely non-depedent nor worry about the political climate of the Middle East.
We have discussed Alice Springs or other areas to implement such an experiment.
The first step to stopping our dependency on Midlde Easter oil is akin to blokcing the vast amouns of drugs flowing through America. Stop the demand and provde an alernatie.
American oil companies would not be happy about hthis. A Hybrid yes- a competely self-suffcent vehicle running on sun power like a calculator- a corporation buster.
Going through through the motions instead coming up with simple solutions for our energy crisis and giving our auto industry to other countries and jobs is why we are in so much trouble.
Free energy devices are barred from patent applications. They would be the death of he world power company and the the birth of a new America.
There are extremely simply solutions to many of our crises yet they would cost the offshore stars megabucks in perks and pina coladas lost. Such is American now.
The Tesla Roadster ...................................
California-based Tesla Motors unveiled its electric-powered roadster at an event in Los Angeles yesterday. The 240-horsepower, battery-powered sports car goes from 0 to 60 in about four seconds, has a top speed of around 130mph, and costs a penny per mile to drive, according to Tesla executives. This venture began in 2000, when Elon Musk, PayPal founder and chairman of Tesla Motors, approached an electric car company with the idea of creating an electric sports car.
As the commercial model of India's microcar is unveiled, U.S. carmakers would do well to learn from the innovations that brought it about
By Jessie Scanlon
When Tata Motors (TTM) unveiled a prototype of its Nano microcar at the Delhi Auto Show in January 2008, auto executives around the world were aflutter. Quickly, they hustled teams to India to document the planned $2,000 "people's car." And industry watchers and innovation experts soon reported on the engineering and supply-chain breakthroughs behind the car.
Electrovaya plans to develop and sell its integrated advanced battery storage systems with NKE, a maker of power distribution equipment with plants in Japan, China and Vietnam, it said.
This is not as complex as it might seem. And despite many commentaries a few layman clear solutions are available and being pursued by by companies in Silicon Valley. Beginning with the more down to earth one- a pure solar energy car powered by a special fiber which can be mounted in a square to two square foot weather protected zone o the roof of a car (except in West Virginia). Here we have only a few sunshine days a year and tje use pf Sun cars would not work that well. jb
Med you're drifting into areas that you have very little understanding about. What one or two square foot solar panel is going to charge an electric car up in less then six months let alone a day.
I'm for Electric Cars but it's funny to see people claiming to be experts that make statements that are totally unrealistic. Even if your solar panel dream car was 100% efficient it would be almost useless. For example the $101-$110K Tesla is light, aerodynamic and very efficient. From the wall outlet to the charger to the battery it's 98.8% efficient. Those batteries are:
53 kWA-h (Li-ion batteries) That would take 53,000 watt hours to charge them not even counting inefficiencies.
Our current solar cell technology is under 16 watts per square foot. Sure we have higher efficiency then that in labs but those panels have with no glass or protection at all and the light on many of those lab cells are artificial and not even matching the suns broad spectrum. They are not at all suited for consumer use. We even hit almost 20 watts per square foot for a thin film solar panel but even at 20 watts per square foot that would take 26,500 hours of sunlight (using a 100% efficiency charger) per square foot to charge a Tesla so it can go 243 miles one time.
The best spot in the US is 6 hours of solar insolation per day in perfect no tree conditions. That's in the desert where less then 1% of the US population lives. The rest of the country is worse and who want's to park their car in the sun 7 days a week to save a penny or two per day on electricity? 120 Watts per square foot per day would be breaking records with the solar panels we have today. Giving your largest two square foot plan. It would take your Solar car 220.83 days to charge the batteries just once not counting sell discharge issues. That's with a Perfect 100% efficiency charger and "better" then the best solar cells we even even use on homes today and you're car sitting in a the best solar insolation spot in the country.
California-based Tesla Motors unveiled its electric-powered roadster at an event in Los Angeles yesterday. The 240-horsepower, battery-powered sports car goes from 0 to 60 in about four seconds, has a top speed of around 130mph, and costs a penny per mile to drive, according to Tesla executives. This venture began in 2000, when Elon Musk, PayPal founder and chairman of Tesla Motors, approached an electric car company with the idea of creating an electric sports car.
Disclaimer: I own many electric Vehicles and Electric vehicles are going to change the way many of us will soon drive. I'm just trying to be practical. If you have $100K+++ to play with then it's a fun toy but it's not cheaper then driving a gas vehicle.
Mary, I've done the numbers on the Tesla before and in California with Tax, Registration fees, vehicle cost, electric cost, replacement parts that car will run about $1.40 per mile to operate for the first 100K miles. In the cheapest state is will still be over $1.30 per mile not 1 penny per mile. Several times the cost per mile of a Hybrid or 30-40 mpg gas vehicle.
The Tesla is $101,000 but you'll walk out the door paying about $110,000 + Tax and Registration. That's well over $120K. The $7K incentive will knock it down to $113K or so. The Tesla has 53 KWh batteries and the extra electric costs in CA will push you up 450KWh per month based on 15K miles per year. That pushes people into the 25-30 cent per KWh range as you'll be two tiers higher. So in Cal expect $3-5K in extra electric costs for that first 100K miles. The Charger is $3,000 alone + you'll need 240 Volt 70+ Amps Service wired into your house. Add $2K and don't even think of buying one if you don't own your own home. Where are you going to find a 16.8KW Charger spot in a complex or apartment or parked on the street. Enclosed garages only and that cuts out a good deal of the population for now.
Then that battery pack is only rated for 100K Miles or 7 years and then it needs replacement. Today it Costs $36,000! In 7 years the price should drop so lets say it only costs $12,000 that's 2/3rds off. So now we are at $139K + 3 sets of tires and brakes. So that pushes us over $142K for the first 100K miles or $1.42 per mile. I haven't even mentioned most repairs and other service related issues or finance charges. Now you might be thinking, It will still be awesome in 7 years. Doubtful as were talking about a 7 year old Electronic device and we know how fast electronics become outdated. By the time this vehicle is 7 years old it will seem slow, will it even be all wheel drive like the newer models? It will only have a fraction of the range as we are dealing with electronics, computers and batteries that are quickly advancing. It will pretty much be electronically outdated and I would guess some type of Mod car will be around by then. Cars where you build them almost by yourself with modules. You pick the batteries, motors, chargers, controllers and trick them to your spec. You can upgrade and swap parts when you have more money. Google will probably make it :)
Great commentary... Thanks for your contributions to the thread. I will be putting up all types of info here. It's up to individuals to make their own judgements on it..
I do not personally back everything I post, as you know.
I bought a bit of electrovaya. They branched out to assist Japan with a back up to their Grid. Electrovaya has a hand in many pots :) I am long on it.
True... I checked up on an earlier post to see if there is any progress... there is some.
Large Power companies are slowly making inroads ... new Nuke Plants are ...sneaking in
and there is this plan... Where Duke Energy has made moves... near Casper Wyoming.
Duke Energy Brings Wyoming Wind Power Project On Line (Company Added 362 Megawatts in 2009)
December 01, 2009
...Duke Energy’s Campbell Hill Windpower Project near Casper, Wyo., is now on line and producing clean, renewable electricity.
The 99-megawatt (MW) Campbell Hill project, located in Converse County, supplies wind energy to PacifiCorp under the terms of a 20-year power purchase agreement. Campbell Hill’s 66 wind turbines produce enough electricity to power approximately 30,000 homes annually.
The Foote Creek Rim wind project is Wyoming's first commercial facility to generate electricity from wind. Located near Arlington, Wyoming, it began commercial operation on Earth Day, April 22, 1999. The project is partially located on public lands managed by the BLM Rawlins Field Office. The project is the largest in the intermountain West.
Foote Creek Rim is a remote, treeless plateau between Laramie and Rawlins in southeastern Wyoming. The flat rimrock is one of the windiest places in America, with average winds speeds of 25 mph - 25 to 70 percent faster than other good wind sites. Strong, steady winds mean that the Wyoming Wind Energy Project can provide power more reliably than almost any other wind farm in the country, delivering an average of 43 percent of its peak power year-round.
The original project had an output of more than 85 megawatts of electricity, enough for about 27,000 average homes. Electronic control systems point each turbine into the wind and adjust the pitch of the blades to make the best use of wind at any speed. The turbines can generate power at wind speeds of 8-65 mph. At higher speeds the turbines automatically shut down - a feature which allows them to withstand Wyoming's 125-mph gusts. The turbines are also adapted to operate reliably in extremely cold conditions.
Since development of the original 69-turbine project, several subsequent phases have been constructed, and the project now totals 183 turbines with a generating capacity of 134.7 megawatts.
Quote: "GlobalData anticipates that annual solar PV installations in the US will increase from 280 MW in 2008 to 1,515 MW by 2013. The cumulative solar PV installed capacity is expected to reach 5,293 MW by 2013."
Nuclear plant production went into a 20 year stall from people complaining about safety. It greatly effected our ability to move to electric vehicles, killed our GNP and increased our dependance on foreign oil. Now Obama is pushing for $54 billion in new Nuclear plants but they take about 8-10 years to build from conception to being operational.
We don't have the Electricity to jump into electric cars yet as they will tax the power grid. One electric car in a home will on average increase electric usage 50-80% and we are still at the edge of rolling brownouts. So until we build up our power grid electrics will take time to replace gas vehicles.
Going electric full scale has huge obstacles that would take 1-2 decades to correct. That's one of the reasons hybrids are doing better. They can recharge themselves when needed. We would need millions of recharge stations. Gas stations would need to add recharge stations, so would hotels, vacations spots, businesses, airports and the list never ends. Recharging an electric vehicle is not a 3-5 minute deal and they currently take hours so many would be more like rest stops or truck stops until we build a higher C charge rating battery or have swappable batteries.
One other issue is that Electrics have the potential to slow down freeways. Sure the $100K Tesla with a 240+ mile range can make a 100 mile trip at 75mph but a $20K economy version with a 120 mile range can't. It will have lower capacity batteries and be more boxy so air resistance will be a larger factor. 75mph on a 120 range electric might turn it into a 60-70 mile range vehicle. So some people might slow down to 30-50mph to save those last few KWh's to make it home.
Remember that the power to overcome air resistance increases roughly with the cube of the speed. In an electric vehicle that speed might be 15-30mph not 25-65mph as in a gas vehicle.
Gas cars have an optimal efficiency at a much higher MPH then electrics do. You need to overcome tire friction just to keep the car rolling but Gas engines also need to overcome displacement inefficiencies as they are burning fuel at idle and are more efficient at certain MPH's. I have a 2008 Ford F350 Superduty Diesel Twin Turbo 4X4 Lariat. I've messed with every gear and speed combination and optimal fuel efficiency is at 55mph. If I drive 40mph I get less mpg then 55. That's odd but it's important to know. I get about 21.5mpg at 55. I get 13mpg at 75mph.
BTW: Everyone should learn their vehicles optimal fuel efficiency speed. If you're almost out of gas do you drive 30mph or 60mph to make it to the gas station? You'll find that every car has a different sweet spot. Finding that sweet spot might be the difference of traveling 15 miles or 30 miles before you run out of gas. You can do it pretty quickly if you're on a flat road on a calm (no wind) day. Drive different speeds and watch your fuel milage computer. Get to a speed and reset it. Breaking it down to 5mph increments is fine. Just get to that speed and reset your computer each time. Just a few miles will give you a pretty good idea if the road is flat Try 70mph then 65mph and work your way down until the milage drops off. That magic speed is in there. Downshifting is normally not needed, just run in overdrive. Oddly many vehicles have two peaks but the lower peak is harder to find as it might involve traveling at 30mph or in a lower gear. Worth noting if you have the time and desire to figure it out.
