Drive Smart: 10 Ways to Save Petrol and Money

Want to save 20% or more on fuel costs? Follow these 10 simple tips from the Consumer Federation of America.

Check Your Air Filter

A clean air filter can improve gas mileage by as much as 10%, and nearly one in four cars needs an air filter replacement.

Cost Savings: 28 cents a gallon.

Straighten Up

Poor alignment not only causes tires to wear out more quickly, but also forces your engine to work harder, which can reduce fuel economy by as much as 10%.

Cost Savings: 28 cents per gallon.

Tune Up

A properly tuned engine can improve mileage by 4%.

Cost Savings: 11 cents a gallon.

Pump 'em Up

More than one-quarter of vehicles have improperly inflated tires. The average under-inflation of 7.5 pounds causes a loss of 2.8% in fuel efficiency.

Cost Savings: 8 cents per gallon.

Check Your Cap

It is estimated that nearly 17% of cars on the road have broken or missing gas caps, which not only reduces gas mileage but may harm the environment.

Cost Savings: 2 cents per gallon.

Slow Down

For every 5 mph you reduce highway speed, you can reduce fuel consumption by 7%.

Cost Savings: 19 cents, by reducing speed from 70 mph to 65 mph.

Drive More Smoothly

The more smoothly you accelerate and decelerate, the better your gas mileage, with potential gas savings of 33% on the highway and 5% around town.

Cost Savings: 48 cents a gallon.

(Don't) Give Your Foot a Brake

Riding with your foot on the brake not only wears out brakes but can also increase gas consumption by as much as 35%.

Cost Savings: 96 cents per gallon.

Lighten Up

For every 100 extra pounds carried around, your vehicle loses 1 to 2% in fuel efficiency.

Cost Savings: 4 cents per gallon, per 100 pounds of weight removed.

Don't Be Idle

Besides causing pollution, idling wastes gas. If stopped for more than 30 seconds, turn off the engine, and don't bother to 'warm up' your car before driving -- it is not necessary.

Cost Savings: 1 cent per gallon, for every two minutes you avoid idling.

Top Clean Car Fuel- Alternative to Petrol

When the automobile was new in 1900, there was no clear consensus which technology would triumph. Would it be gasoline, steam or electricity? The smart money was on electricity, which shows that the smart money can be wrong.

We're in a similar period now, trying to find what comes after the straightforward, gas-burning internal-combustion engine. There's still a lot of fog, and it's unlikely to clear soon. But from where I sit today, here are eight leading technologies, listed in priority order from most-likely to could-be-a-contender:

1. Plug-In Hybrids. There's no question that plug-in hybrids, with 40-mile all-electric range and the ability to recharge from standard house current, will be on the market in the next two or three years. The leading (and only) mainstream players are General Motors (which plans on introducing a Saturn Vue plug-in hybrid) and Toyota (with an adapted Prius). Ambitious startups (Fisker, BYD) are also planning to field plug-in hybrids. The big challenge for all of them is developing a lithium-ion battery pack that can stand up to repeated discharge and recharge cycles and still demonstrate the longevity that today's nickel-metal-hydride hybrid battery packs have had. GM and Toyota talk about 2010 introductions, but battery development headaches could delay that.

2. Battery Electrics. Again, it's all about the batteries. Lithium-ion is the current leader, but is it ready to carry four passengers in a fully featured, crashworthy sedan more than 200 miles? It's time to be cautiously optimistic. Nissan has plans to bring an electric car to the U.S. by 2010. Chrysler, which has been lagging in green technology, surprised the world by suddenly announcing a concept car known as the Dodge EV, a sports car with a lithium-ion battery pack. It claimed 150-mile range and blistering acceleration of zero to 60 in less than five seconds. Some Chrysler electric is to be on the market by 2010. The sports car was clearly aimed at the Tesla Roadster, a California-built $100,000 exotic which (like the Chrysler) sports a Lotus-designed body.

3. Range Extenders. General Motors is making a big, bold step forward by building the Chevrolet Volt, with production slated for the end of 2010 (as a 2011 model). The Volt is something new: an electric car with a gas motor whose only function (it's not connected to the wheels) is to keep the electric motor spinning after the batteries are depleted. GM had this field (also known as "series hybrids") to itself, but Chrysler has jumped into the fray with range-extender versions of the Town and Country minivan and Jeep Wrangler. As with plug-in hybrids, 40 miles can be enjoyed in battery-only mode, but the gas engine extends that to 400 miles or more.

4. Very Small Cars. It doesn't have to be a hybrid; in fact, some of our current hybrids, based on SUVs, are actually gas guzzlers. High fuel prices have created a strong American market for very small cars, and carmakers such as Ford have been emboldened to start selling in the U.S. tiny, fuel- and space-efficient cars once relegated only to Europe or Asia. Consider the Toyota iQ. The minuscule car is just 118 inches long, but can carry three adults (plus a child)! It reportedly achieves 60/51 mpg fuel economy. The Toyota of 10 years ago would never have contemplated selling iQs in the U.S., but now it is definitely being considered.

5. Fuel Cells. The joke is that the hydrogen revolution is always at least 10 years away. And, well, it's still at least that far in the future. But the possibilities are endless, since hydrogen is the most abundant element in the universe. Big drawbacks now are the cost of the fuel and, of course, the cars themselves. Hand assembled by Ph.Ds, fuel-cell cars are way too expensive to be ready for showrooms before 2020. The leading players are General Motors (which has the cutting-edge Sequel and a fleet of Equinox SUVs under test) and Honda (the ready-for-the-road FCX Clarity).

6. Salad Oil. Americans love the idea of running their cars on used fryer drippings. And the technology totally works. Companies such as Massachusetts-based Greasecar have found a niche converting diesels to run on 100 percent biofuel. The problem is standardizing and ramping up the technology so we could seriously make a dent in gasoline power. We simply don't have enough available farmland to run our transportation fleet on soybean-derived oil, and there aren't enough fryers to greatly expand what is now a small cottage industry.

7. Liquid Hydrogen. BMW's Hydrogen 7 is a very impressive car, quiet and powerful. Its 12-cylinder engine will burn gasoline all day, but push a button and it switches without a hitch to a tankful of energy-dense liquid hydrogen. You can drive it anywhere. But things get complicated after that. Hydrogen is expensive to begin with, and it liquefies at -423 degrees Fahrenheit, meaning a super-cooled cryogenic tank is obligatory. Leave the car alone for too long (parked for a week at an airport, say) and much of the hydrogen will return to a gaseous state and vent out. The big challenges: affordable hydrogen production and liquification; easy refueling; and answering safety questions.

8. Ethanol. GM and Ford are world leaders in producing "flex-fuel" vehicles that can run on ethanol or gasoline. Millions have been produced, but most run on gasoline most of the time because of a still-embryonic ethanol station network. Cornell professor David Pimentel claims that ethanol has a net negative energy balance, which the industry heatedly denies. And there's the ramp-up question, too. According to Pimentel, if we converted 100 percent of the U.S. corn crop to ethanol, it would only replace six percent of current fossil fuel use. Because corn is in high demand, prices for it are escalating, creating a "food vs. fuel" controversy. Cellulosic ethanol, produced from plant fiber, has a much higher energy potential, but research is still embryonic.

42% of Asian children are not concerned about environmental protection

In a study conducted by TNS, children aged 3 to 9 in four Asian countries (China, Japan, Malaysia and Thailand) were asked on their level of concern about the need for environmental protection. The results are shown below:

• Very concerned - 15%
• Somewhat concerned - 43%
• Not very concerned - 32%
• Not at all concerned - 10%

The study results suggest that 42% of children in Asia are not very or not at all concerned about the need for environmental protection. This is in contrast to the children’s mothers, who are 95% concerned about the need for environmental protection. Why do a high percentage of our future generation not care about the environment?

Perhaps we are just too harsh on them. They are still young and innocent to understand the need for protecting the environment. Or they do know the need but are more concerned about other things such as schoolwork, toys and computer games or just about having fun.

Regardless of the reasons, there is a need for parents to educate their children and raise awareness about the environment. Since parents know more about the need to protect the environment (as shown in the high 95% concern), they should be the role models and educate our future generation.

Green Computer

Green computing is the study and practice of using computing resources efficiently.
The primary objective of such a program is to account for the triple bottom line, an expanded spectrum of values and criteria for measuring organizational (and societal) success.
The goals are similar to green chemistry; reduce the use of hazardous materials, maximize energy efficiency during the product's lifetime, and promote recyclability or biodegradability of defunct products and factory waste.

Approaches to green computing

• Virtualization

Computer virtualization refers to the abstraction of computer resources, such as the process of running two or more logical computer systems on one set of physical hardware.

With virtualization, a system administrator could combine several physical systems into virtual machines on one single, powerful system, thereby unplugging the original hardware and reducing power and cooling consumption.

• Power management

The Advanced Configuration and Power Interface (ACPI), an open industry standard, allows an operating system to directly control the power saving aspects of its underlying hardware. This allows a system to automatically turn off components such as monitors and hard drives after set periods of inactivity.

In addition, a system may hibernate, where most components (including the CPU and the system RAM) are turned off.

Some programs allow the user to manually adjust the voltages supplied to the CPU, which reduces both the amount of heat produced and electricity consumed. This process is called undervolting.

Some CPUs can automatically undervolt the processor depending on the workload; this technology is called "SpeedStep" on Intel processors, "PowerNow!"/"Cool'n'Quiet" on AMD chips, LongHaul on VIA CPUs, and LongRun with Transmeta processors.

• Power supply

Desktop computer power supplies (PSUs) are generally 70–75% efficient, dissipating the remaining energy as heat.

An industry initiative called 80 PLUS certifies PSUs that are at least 80% efficient; typically these models are drop-in replacements for older, less efficient PSUs of the same form factor.

As of July 20, 2007, all new Energy Star 4.0-certified desktop PSUs must be at least 80% efficient.

• Storage

Smaller form factor (e.g. 2.5 inch) hard disk drives often consume less power than physically larger drives.

Unlike hard disk drives, solid-state drives store data in flash memory or DRAM. With no moving parts, power consumption may be reduced somewhat for low capacity flash based devices.

Even at modest sizes, DRAM based SSDs may use more power than hard disks, (e.g., 4GB i-RAM uses more power and space than laptop drives). Flash based drives are generally slower for writing than hard disks.

• Video Card

A fast GPU may be the largest power consumer in a computer.

Energy efficient display options include:

• No video card - use a shared terminal, shared thin client, or desktop sharing software if display required.
• Use motherboard video output - typically low 3D performance and low power.
• Reuse an older video card that uses little power; many do not require heatsinks or fans.
• Select a GPU based on average wattage or performance per watt

• Display

LCD monitors typically use a cold-cathode fluorescent bulb to provide light for the display. Some newer displays use an array of light-emitting diodes (LEDs) in place of the fluorescent bulb, which reduces the amount of electricity used by the display.

• Materials recycling

Computer systems that have outlived their particular function can be repurposed, or donated to various charities and non-profit organizations. However, many charities have recently imposed minimum system requirements for donated equipment. Additionally, parts from outdated systems may be salvaged and recycled through certain retail outlets and municipal or private recycling centers.

Recycling computing equipment can keep harmful materials such as lead, mercury, and hexavalent chromium out of landfills, but often computers gathered through recycling drives are shipped to developing countries where environmental standards are less strict than in North America and Europe. The Silicon Valley Toxics Coalition estimates that 80% of the post-consumer e-waste collected for recycling is shipped abroad to countries such as China, India, and Pakistan.

Computing supplies, such as printer cartridges, paper, and batteries may be recycled as well.

• Telecommuting

Teleconferencing and telepresence technologies are often implemented in green computing initiatives. The advantages are many; increased worker satisfaction, reduction of greenhouse gas emissions related to travel, and increased profit margins as a result of lower overhead costs for office space, heat, lighting, etc.

The savings are significant; the average annual energy consumption for U.S. office buildings is over 23 kilowatt hours per square foot, with heat, air conditioning and lighting accounting for 70% of all energy consumed.

Other related initiatives, such as hotelling, reduce the square footage per employee as workers reserve space only when they need it. Many types of jobs -- sales, consulting, field service -- integrate well with this technique.

Voice over IP (VoIP) reduces the telephony wiring infrastructure by sharing the existing Ethernet copper. VoIP and phone extension mobility also made Hot desking and more practical.

Go for Green

By Ragunathan Santiagoo and Wong Yee Shian

The advance science and technology have made ways to minimize independence on soil for plant cultivation. The Hydroponics from the Greek words hydro (water) and ponos (labour) is a method of growing plants using mineral nutrient solutions instead of soil. Terrestrial plants may be grown with their roots in the mineral nutrient solution only or in an inert medium, such as perlite, gravel or mineral wool.

Plant physiology researchers discovered in the 19th century that plants absorb essential mineral nutrients as inorganic ions in water. In natural conditions, soil acts as a mineral nutrient reservoir but the soil itself is not essential to plant growth. When the mineral nutrients in the soil dissolve in water, plant roots are able to absorb them. When the required mineral nutrients are introduced into a plant’s water supply artificially, soil is no longer required for the plant to thrive. Almost any terrestrial plant will grow with hydroponics, but some will do better than others.

There are two main types of hydroponics technique. They are solution culture and medium culture. Solution culture does not use a solid medium for the roots, just the nutrient solution. The medium culture method has a solid medium for the roots and is named for the type of medium, e.g. sand culture, gravel culture or rockwool culture.

Advantages of Hydrophonic Method

Compared to the conventional cultivation method it has various advantages. The farmer has full control on the crops, can be planted densely with less rate of fertilizer usage. The crop can also be harvested faster without deteoration of bad climate and pesticides usage. It is capable of producing 2000 tonnes of tomato per hectare per year of land compared to the conventional cultivation of at 50 to 100 tonnes per hectare per year. Saves an incredible amount of water; it uses as little as 1/20 the amount as a regular farm to produce the same amount of food. Hydroponics technology has made high altitude crops species able to be cultivated in temperate climate in Malaysia. Salad Webb Wonderful Lolla Blonda The hydroponics technique is suitable for variety of crops in Malaysia such as in the following.

Type of crop suitable for hydroponics cultivation in Malaysia Crop Category

Vegetable - Salad, cabbage, tomato, chilli, cucumber
Flowers - Rose, orchid
Herbs - Chives, mint, parsley, sage, thyme
Fruits - Banana, watermelon
(Source:Terangganu Hydroponics Association, 2006)

The most common technique used in hydrophonic cultivation for farming in malaysia is the continuous flow culture which are known as the “nutrient film technique”. In this technique the nutrient solution constantly flows past the roots. Whereby a very shallow stream of water containing all the dissolved nutrients required for plant growth is recirculated past the bare roots of plants in a watertight gully, also known as channels. Ideally, the depth of the recirculating stream should be very shallow, little more than a film of water, hence the name ‘nutrient film’. A properly designed NFT system is based on using the right channel slope, the right flow rate and the right channel length.

Do It Yourself (DIY)

As for beginners or any household may try them which is relatively easy to be carried out. Plants can be grown in containers of nutrient solution such as, plastic buckets, tubs or tanks. The solution is kept low enough that sufficient roots are above the solution so they get adequate oxygen. A hole is cut in the lid of the reservoir for each plant. A homemade system can be constructed from plastic food containers with aeration provided by an aquarium pump, aquarium airline tubing and aquarium valves. Clear containers are covered with aluminium foil, butcher paper, black plastic or other material to exclude light, thus helping to eliminate the formation of algae. The nutrient solution is changed on a schedule, such as once per week.

Conclusion

Hydrophonic technique of plant cultivation may serve as a solution for food shortage due to the rapid industrialization and global environmental changes. The basics of this technology can be explored by starting our own vegetable cultivation in the kitchen yard. Without doubt it will produce much yield and benefits to its owner if the culture is made with a little attention. Let us go green Malaysian, cultivate your own food, it may worth a lot for the embraces.

Green Building

By Ahmad Firdaus bin Ahmad Fuad
Environmental Analysis Group, Malaysia


Green Buildings are eco friendly, reduce operating costs, increase marketability of the building and enhance the owners’ corporate image as they also increase productivity of the occupants and reduce potential liability resulting from poor indoor air quality problem.

Green building is the practice of increasing the efficiency with which buildings use resources — energy, water, and materials — while reducing building impacts on human health and the environment during the building's lifecycle, through better siting, design, construction, operation, maintenance, and removal.

Green buildings are designed to reduce the overall impact of the built environment on human health and the natural environment by:

• Efficiently using energy, water, and other resources
• Protecting occupant health and improving employee productivity
• Reducing waste, pollution and environmental degradation

Studies of people working in green buildings have reported productivity gains of 16%, including reduction in absenteeism and improved quality of work. Essentially, Green Building designs incorporate positive environmental, economic and social elements that benefit all building stake holders, including owners, occupants and the general public.

Green Buildings, sometimes referred to as “Sustainable Buildings” or “Environmental Buildings”, are designed to enhance energy efficiency, promote renewal energy, reduce air-conditioning costs and improve indoor environment quality (both temperature and relative humidity), and in the process, enabling owners to reap financial incentives under the Kyoto Protocol’s clean development mechanism.

While some countries in the region like India, Singapore and Australia have developed their own Green Building Councils and Rating Standards derived from the LEED in the US, Malaysia is still in the process of forming a Green Building Council, while even countries like Vietnam have taken a lead.

Malaysia needs to hasten the process to catch up with the world as many countries have gone even further.

Many countries have developed their own standards of energy efficiency for buildings. Above some examples of building environmental assessment tools currently in use:

• Australia: Nabers / Green Star

• Brazil: AQUA / LEED Brasil

• Canada: LEED Canada / Green Globes

• China: GBAS

• Finland: PromisE

• France: HQE

• Germany: DGNB

• Hong Kong: HKBEEM

• India: LEED India/ TerriGriha

• Italy: Protocollo Itaca

• Mexico: LEED Mexico

• Netherlands: BREEAM Netherlands

• New Zealand: Green Star NZ

• Portugal: Lider A

• Singapore: Green Mark

• South Africa: Green Star SA

• Spain: VERDE

Panduan Penjimatan Tenaga Bagi Mengatasi Kenaikan Kos Hidup Akibat Kenaikan Harga Minyak

Sebagai panduan untuk jimatkan bil letrik ( tariff baru lagi mahal nanti)

Berikut adalah caranya

Kecekapan Tenaga (Energy Efficiency)

- set suhu air cond pada suhu antara 25-27 Celcius, jgn sejuk sgt
- klau tutup TV untuk tempoh yang lama, jgn just off pki remote, terus off kat plug.
- komputer pun sama gak, off kat plug, klau off kat CPU, electric still pki.
- jgn guna lampu mentol, pki compact fluorescent lamp (CFL)
- penggunaan Daylight di siang hari, so krg pki lampu, so pki le langsir yg transparent.
- penggunaan LCD monitor lebih menjimatkan berbanding CRT

Ada banyak lagi cara, nnt lain kali kite bincang lagi.

Lampu Fluorescent ( T5 and T8)

Umum sedia tahu bhw lampu fluorescent jenis T5 lebih menjimatkan berbanding jenis T8.
Tetapi penggunaan T5 masih amat kurang terutamanya penggunaan di rumah kerana kurangnya kesedaran serta pengetahuan terhadap 'Cekap Tenaga'.

Sebagai panduan, lampu t5 hanya menggunakan tenaga sebanyak 28W dengan efikasi sebanyak 104 lumen / Watt berbanding t8 yang menggunakan tenaga sebanyak 36W dengan efikasi sebanyak 68 lumen / Watt. Dengan ini penggunaan lampu T5 bukan sahaja menjimatkan tenaga tetapi juga menjimatkan kos lampu kerana menggunakan kurang lampu berbanding T8.

Lampu T5 juga tahan lebih lama iaitu sebanyak 24000 jam penggunaan berbanding T8 hanya 5000 jam penggunaan.

Kos permulaan bagi penggunaan T5 adalah lebih tinggi tetapi untuk jangka masa panjang ianya amat menjimatkan. Payback period bagi penggunaan T5 adalah antara 2- 3 tahun bergantung kepada penggunaan.

Green Practices in The Hospitality Industry

Pretty much everyone these days is getting environmentally conscious; in fact, the Tourism industry has long since been following green ways. But this was quite limited to the extent of reusing towels or saving power consumption. However more and more hotels and restaurants are coming out with new ways and means to go green and woo the environmentally conscious customer. Many customers are choosing hotels or resorts that advertise and practice as being environmentally conscious.

Many businesses have realized that by going green in a big way, it's serving a dual purpose. One, they are gaining foothold in terms of their reputation. Two, in the bargain they are saving a lot.

So, what are some of the energy saving ways that hotels/restaurants or the hospitality business are using?

Energy Efficiency in Building

Energy Efficiency in Buildings means use less energy for heating, cooling and lighting. It also means buying energy-saving appliances and equipment for use in a building.

The important concept for energy efficiency in buildings is the building envelope, which is everything that separates the interior of the building from the outdoor environment: the doors, windows, walls, foundation, roof, and insulation. Various approaches could be done to improve the building envelope. For instance, windows with special glazing can let in daylight without heat gain and storm windows and doors can reduce heat loss when temperatures drop. These techniques can significantly improve a building's energy efficiency.

Cooling and lighting systems typically use the most energy in a building in our country. The addition of efficient controls, like a programmable thermostat, can significantly reduce the energy use of this system. For commercial buildings, maximizing the use of Building Energy Management System (BEMS) can provide the best approach to energy-efficient cooling. The energy used to heat water can be reduced by both heating water more efficiently and by reducing hot water use especially in hotel and hospital application. A wide variety of fixtures, such as low-flow showerheads and faucet aerators, can reduce hot water use. In a home, the older water heater can be replaced with a newer, more energy-efficient one, and the water heater and hot water pipes can be insulated to minimize heat loss.

Today, most common appliances and electronic devices are available in energy-efficient models—air conditioner, washing machines, fans, refrigerators, copiers and computers. Several energy-efficient lighting options, such as compact fluorescent light bulbs, are also available. There are many ways to determine energy efficient in building, measures and improvements can be made. Owners can conduct energy audits on their premises or have professional audits done.

During the commissioning of new commercial buildings, a number of tests and adjustments can be performed to ensure that the heating, cooling, lighting, ventilation, and other mechanical systems work together effectively and efficiently. Once the systems are commissioned, their proper operation and maintenance is critical to efficient energy use.

Green Technology

Green technology (abbreviated as GreenTech) or clean technology (abbreviated as CleanTech) or Environmental Technology (abbreaviated as EnviTech) is the application of the environmental sciences to conserve the natural environment and resources, and to curb the negative impacts of human involvement. Sustainable development is the core of environmental technologies. When applying sustainable development as a solution for environmental issues, the solutions need to be socially equitable, economically viable, and environmentally sound.

Some environmental technologies that retain sustainable development are; recycling, water purification, sewage treatment, remediation, flue gas treatment, solid waste management, and renewable energy. Some technologies assist directly with energy conservation, while other technologies are emerging that help the environment by reducing the amount of waste produced by human activities.

Energy sources such as solar power create less problems for the environment than traditional sources of energy like coal and petroleum. Scientists continue to search for clean energy alternatives to our current power production methods. Some technologies such as anaerobic digestion produce renewable energy from waste materials. The global reduction of greenhouse gases is dependent on the adoption of energy conservation technologies at industrial level as well as this clean energy generation. That includes using unleaded gasoline, solar energy and alternative fuel vehicles, including plug-in hybrid and hybrid electric vehicles.

Since electric motors consume 60% of all electricity generated[citation needed], advanced energy efficient electric motor (and electric generator) technology that are cost effective to encourage their application, such as the brushless wound-rotor doubly-fed electric machine and energy saving module, can dramatically cut the amount of carbon dioxide (CO2) and sulfur dioxide (SO2) that would otherwise be introduced to the atmosphere.
