CNG Advatages and Disadvantage


Most of today we are preffering to out by using vehicles either on Car or by two-wheeler.In previous year  most of the vehicles were using petrol as fuel resource to their vehicles and trucks and heavy loaded vehicles were using desiel as fuel option. But as the technology improved and new fuel which energy saving and less pollution free resource is CNG.Natural gas, a fossil fuel comprised mostly of methane, is one of the cleanest burning alternative fuels. It can be used in the form of compressed natural gas (CNG) or liquefied natural gas (LNG) to fuel cars and trucks.
Dedicated natural gas vehicles are designed to run on natural gas only, whiledual-fuel or bi-fuel vehicles can also run on gasoline or diesel. Dual-fuel vehicles allow users to take advantage of the wide-spread availability of gasoline or diesel but use a cleaner, more economical alternative when natural gas is available. Since natural gas is stored in high-pressure fuel tanks, dual-fuel vehicles require two separate fueling systems, which take up passenger/cargo space.

Green Computing


Green Computing
Mandanikashmira, Chohala Meera

 Green Computing is called as Green IT.It’s environment friendly IT where the main Objective is to reduce the hazardous  materials and maximize the energy efficiency.It means "the study and practice of designing, manufacturing, using, and disposing of computers, servers, and associated subsystems—such as monitors, printers, storage devices, and networking and communications systems — efficiently and effectively with minimal or no impact on the environment." The goals of green computing are similar to green chemistry; reduce the use of hazardous materials, maximize energy efficiency during the product's lifetime, and promote the recyclability or biodegradability of defunct products and factory waste.
 ·       Green Computing is required due to following reasons:
-Computer consumes a lot of energy.
-so, we must have to reduce the power consumption and thus reduce the global warming.
-to reduce pollution
-to reduce toxicity.

1.     What is different about “Green”?

One cannot achieve a Sustainable Strategy with a product, it takes an Architectural commitment.
-The corporate architect must realize that the impact corporations make on the environment now is engrained in doing business:
            -Executives are allocating time, energy and money to invest in environmental initiatives.
-Governments are allocating research and regulations, and laws are being written to         address the efficiency of data centers and other critical components of IT infrastructure.
- Consumer advocates, policy makers and influential industry leaders are promoting IT organizations to significantly confront the impact that computing and electronics make on the environment.
-This is a vastly different landscape than for other galvanizing themes such as SOA, agile design, or Web 2.0 and SaaS. Those themes did not elicit the same degree of regulatory, legal, and advocacy. Ten years from now, those initiatives may not exist in their present incarnation, but commitments to reduce environmental impact and power consumption will continue to be
-important objectives for organizations.
-As the commitment to reduce environmental impact and power consumption are becoming increasingly important objectives for organizations, architecture leaders are now proactively considering environmental resource constraints along with more traditional IT business goals.
-Rather than viewing the environmentally sustainable data center as a product feature checklist for a onetime win, serious IT architects are adopting a more comprehensive sustainability plan in their data center system design. While new technology from the industry
-continues to drive efficiency into the IT infrastructure,

1.     Energy consumption by computer

-CPU uses 120 watts
-CRT uses 150 watts
-Energy use comes from
            * electric current to run CPU , motherboard,             memory.
            * Running the fan & Spinning the disk.
            * Monitor(CRT consumes more power  than any  other computer component.)
            * Printers.



           
2.     Problems and causes with computers on global warming

1.      Leaving the computer when in not use..
(Screen savers, CPU, Fan consumes more power)
2.      Printing  is often wasteful
We are used to printout our works.
3.      Pollution via electronics
Manufacturing techniques
Packaging
Disposals of computer parts or any electronic item part..

4.      Toxicity
There are many toxic materials used in computers. But two materials are very toxic.
Problems:
      Cause damage to nervous system , blood system , kidneys, and also cause negative effects on child brain development
      Also has toxic effects on plants, animals and microorganisms .
      can cause chronic brain damage.

1.     Solution

ü  Keep PCs  turned off, when not in use.
ü  Disable screen saver.
ü  Don’t print until  it is necessary.
ü  Use LCDs  instead of CRTs as they are more power efficient.
ü  Use hardware/software  with “energy star” label. It is the “seal of approval” by Energy Star Organization of the government.
ü  Set low power “Sleep” mode.
-can still download and perform other routines.
ü  Stand By
-it is energy conserving because switches to a “low power state.”
ü  Hibernate
-It writes an image of what you are currently working on your file/hard drive and then shutts        your PC almost completely off.
ü  Use Email to reduce paper work
ü  Add: “*Please Consider the environment: Do U really need to print this mail?*”
            (put entire message in Subject line.)
ü  Place Information web-page, wikis instead of making paper copies.
(online resource consume 90% less energy and produce 85% fewer co2 emissions.)
ü  Recycling E-waste:
ü  Developed countries have now facility of recycling e-waste.
ü  Greener Google Browsing:  Blackle.com
ü  Being Green with Yahoo!
ü  Greener FireFox Surfing
