(NC)-Hold your arms out at your sides like the person in this illustration, and imagine there’s the same kind of bubble around you. That’s roughly the space 1 kg of CO2 takes up - the amount produced by every litre of gasoline you burn. Gasoline and diesel - which are injected into the engine as a mist of fine droplets - require oxygen to burn. That oxygen comes from air, but air is only 21% oxygen. So it takes about 8,000 litres of air, weighing almost 12 kg, to burn 1 litre of gasoline or diesel. And with so much air involved in the process - and with gasoline and diesel both containing large amounts of carbon to begin with - a lot of CO2 comes out the other end. It’s chemistry.

(NC)-Some car rental agencies in Canada are now offering hybrid vehicles to their customers in a bid to be more environmentally friendly. Not only does that offer consumers a great way to conserve energy when renting a vehicle, it also gives potential vehicle buyers the chance to “try before they buy.” By combining an internal combustion engine with an electrical motor and battery pack, most hybrids today achieve improvements in fuel efficiency by using the electric motor to supplement engine power. Some hybrids can also operate exclusively using the electric motor at low speeds. Batteries do not require plugging in and are recharged by harnessing the energy from coasting, braking and from the engine. Ask your favourite rental agency if they rent hybrids and give one a try. Your wallet and the environment will thank you. There are more tips on fuel-efficient driving at ecoaction.gc.ca/vehicles.

(NC)-Look for these modern technologies when shopping for a new or used vehicle and watch your fuel savings go up:

. Variable valve timing and lift: improves the flow of fuel and air during the engine cycle by varying the opening and closing of the engine valves depending on need. The technology can result in both greater power and better fuel efficiency.

. Cylinder deactivation allows V-6 and V-8 engines to operate as though they had fewer cylinders. While cylinder deactivation cannot decrease the weight of engines, it does reduce fuel consumption under light-load highway cruising conditions by only delivering fuel to activated cylinders.

. Gasoline and diesel direct injection uses sophisticated electronic fuel-flow and air-flow controls, and precision injectors which inject the fuel directly into the cylinder and optimize the ideal mixture of air and fuel during combustion.

. Continuously Variable Transmission or CVT’s don’t have a gearbox with a set number of gears, instead they typically operate on a pulley configuration that allows an infinite number of engine/wheel speed ratios. This technology results in better engine speed matching, ideal “gear” selection and improved fuel efficiency.

. Hybrid Technology: by combining an internal combustion engine with an electrical motor and battery pack, most hybrids today achieve improvements in fuel efficiency by using the electric motor to supplement engine power. Some hybrids can also operate exclusively using the electric motor at low speeds. Batteries do not require plugging in and are recharged by harnessing the energy from coasting, braking and from the engine.

. Electronic throttle control responds to changing engine conditions and precisely controls fuel combustion. Decreased amounts of unburned fuel result in improved fuel efficiency.

More than half of the ethanol plant’s natural gas usage will be replaced by fuel generated from waste.

Sioux Falls, SD (Vocus/PRWEB ) November 15, 2007 — An expansion of a POET ethanol plant includes a technology that will allow ethanol production to double without increasing fossil fuel usage. POET Biorefining - Chancellor, an ethanol production facility near Chancellor, S.D., is undergoing an expansion that will increase production capacity from 50 to 100 million gallons per year. The expansion includes construction of a solid waste fuel boiler, an alternative energy source that will generate enough steam to produce more than half of the expanded plant’s power needs. Mueller Pallets of Sioux Falls, S.D. will supply woodchip fuel for the boiler.

“The solid waste fuel boiler will allow us to double our production capacity without increasing our natural gas usage,” said Rick Serie, General Manager of POET Biorefining - Chancellor. “We’ll be reducing our operating costs by using a green fuel source to produce a domestic, green transportation fuel for America.”

Waste wood from pallets, construction sites and area landfills will be the primary fuel source for the solid waste fuel boiler. POET Biorefining - Chancellor has contracted with Mueller Pallets of Sioux Falls to provide 150-350 tons of wood per day. The company, long a recycler of used transport pallets, has increased operations to accommodate POET’s woodchip needs. Not only has Mueller begun acquiring and grinding waste wood from area landfills, but the company is also reaching out to tree services companies, contractors and other private sources to acquire and re-cycle waste wood at no charge to the providers.

“It’s a win-win situation. By recycling instead of disposing of waste wood, companies, cities and towns in the region will together save hundreds of thousands of dollars in landfill costs yearly,” said Margie Mueller, president of Mueller Pallets. “And while saving raw materials from disposal, the fuel product we process will help reduce the need for natural gas.”

POET Alternative Energy Engineer Jim Geraets said the solid waste fuel boiler will be outfitted with state-of-the-art pollution control equipment that exceeds state and federal standards and continuously monitored. “Ethanol is one of the best tools we have to fight pollution from vehicles,” said Geraets, “and at POET we’re always looking for ways that we can make the ethanol production process even more environmentally-friendly.”

POET Biorefining - Chancellor started operations in March, 2003. Last year, the facility produced 51 million gallons of ethanol and 160,000 tons of Dakota Gold Enhanced Distillers Nutrition products. The facility is in the midst of an expansion that will increase the production capacity to 100 mgpy. Construction on the expansion is expected to be completed in Q1 2008 and the solid waste fuel boiler is expected to be complete in Q3 2008. The construction will necessitate the hiring of approximately 20 additional employees for the facility, which is already the largest employer in the town.

About POET:
POET, the largest ethanol producer in the world, is an established leader in the biorefining industry through project development, design and construction, research and development, plant management, and marketing. Formerly known as Broin, the 20-year old company currently operates 21 production facilities in the United States with six more in construction or under development. The company produces and markets more than 1.1 billion gallons of ethanol annually. For more information, go to http://www.poetenergy.com

The Pontiac G6 is one of many GM vehicles that achieve better than 7L/100km on the highway.

(NC)-The environment has quickly become an important priority for many Canadians. In fact, fuel economy is now the second most important factor for drivers when considering a new vehicle purchase and recent polling revealed more than one quarter of Canadians view the environment as a top issue.

Automotive manufacturers continue to make improvements to the internal combustion engine to maximize fuel efficiency and reduce both smog and greenhouse gas emissions. Priority focus has also been placed on developing new, environmentally-friendly technologies including hybrids, bio-fuels, electric vehicles and fuel cells.

“GM Canada offers more green choices for consumers and we are taking an active role in developing environmental technologies,” says David Paterson, vice president, corporate and environmental affairs, General Motors of Canada. “GM is the green technology leader in Canada, engineering and manufacturing advanced environmental technologies ranging from active fuel management and hybrid systems to E85 biofuel and fuel cell vehicles.”

In addition to these new developments, there are steps drivers can take to improve the fuel efficiency of their vehicles every day:

1. Plan your trips and driving routes to avoid traffic congestion

2. Observe speed limits

3. Accelerate smoothly

4. Maintain steady speeds

5. Limit the use of accessories

6. Don’t carry more than you need

7. Make sure your vehicle is properly maintained - proper tire pressure, clean your air filter etc.

For Canadians who typically drive 64 kilometers a day or less, the plug-in Chevrolet Volt would eliminate trips to the gas station and produce zero emissions

(NC)-”Green” and environmentally-friendly vehicles are top of mind for Canadians these days. With daily commute times and distances increasing annually, consumers are clamoring for vehicle technology that makes their drive safer, more enjoyable and, most importantly, more efficient and cost effective.

With technologies ranging from hybrids to cylinder deactivation, whereby the engine shuts down half the vehicle’s cylinders when you don’t need them, there has never been more “green” vehicle choices for consumers.

Even with these advancements, automotive companies are continuing to develop alternative technologies to take “green” to the next level. General Motors, for example, recently unveiled a new electric concept, the Chevrolet Volt, which will potentially redefine the urban driving experience.

The Volt is a plug-in, electrically-driven car that will virtually eliminate trips to the gas station for those who drive 64 kms a day or less. Drivers will simply unplug and go each morning. Onboard electricity can be generated from a fuel cell, bio-fuel engine, or conventional small displacement gas engine.

In addition to plug-in vehicles, fuel cells are another key research area for developing environmentally-friendly vehicles. Fuel cell vehicles only emit water vapours and will virtually eliminate the vehicle from the environmental equation.

There’s no silver bullet out there to fight climate change, but automotive companies are working hard to continue to develop affordable solutions for all drivers.

The fuel efficient Chevrolet Impala achieves better than 7L/100km highway fuel consumption and features advanced technology such as Active Fuel Management.

(NC)-According to a recent Stats Can report, the average Canadian spends more than an hour a day - or 12 full days a year - trekking to and from work. With these longer commute times, fluctuating gasoline prices and concerns about the environment; consumers and governments are looking for new automotive technologies that reduce emissions and save fuel.

While hybrids have received the majority of attention, many drivers may be surprised to know that improvements to regular gasoline engines are actually saving more fuel overall than the savings produced by small hybrid cars.

Cylinder deactivation technology, for example, is one of the largest contributors to total greenhouse gas reductions in Canada. This technology works by seamlessly shutting down half of the engine’s cylinders when they are not needed, such as highway driving.

General Motors’ application of this technology called Active Fuel Management (AFM), offers up to a 12 per cent or better fuel consumption improvement.

“GM Canada offers more green choices for consumers than any other manufacturer,” says David Paterson, vice president, corporate and environmental affairs for General Motors of Canada. “Technologies such as Active Fuel Management (AFM) have the potential to dramatically reduce fuel consumption and are available to drivers for no additional cost. Consider this - in the first half of 2007, more fuel was saved by the application of AFM on new GM vehicles in Canada (and therefore more greenhouse gas was reduced) than was saved by new hybrid vehicles sold by any competitor in the same time period.”

With drivers now focusing on saving fuel as well as helping to save the environment, the affordable technologies on the market today will enable Canadians to go green without going broke.
