Office building with 100% LED lights.

Here's an example of an office building that has been converted to 100% LED light. The new bulbs consume 48% less energy than those they replaced (mostly fluorescents lights). The workplace in question is the headquarters of Cree, a company in North Carolina that specializes solid-state LED lights. The parking lots, entryways, lobby and conference rooms at Cree’s headquarters are now lit by eco-effective XLamp LEDs. Even the high-pressure sodium parking lights and spotlights were converted to LED lights.

Cree wanted to demonstrate that LED lights are a viable option today for businesses and residences. The company claims that their lights render the same type of light that is produced by fluorescents or incandescents. It looks like the LEDs in the photo above are producing a full-spectrum light.

When LEDs replace incandescent bulbs, there is also the added advantage of reducing AC requirements in the summer.

The only method of lighting more energy efficient than LEDs is daylighting (e.g. through the use of sun tubes, for example).

India Inc turns green

The corporate sector is designing innovative products and programmes to improve energy efficiency, cut costs and counter global warming

One of the most frequently used key combinations to log off a PC is ‘Ctrl+Alt+Del’. But every time we do this and walk away, the computer remains on and consumes energy, resulting in wastage of both money and power. Not just that, the power consumed by your PC also adds to global warming! A 65 watt power processor in a computer consumes about 234 KW power if it works for 12 hours a day for 300 days. If there are an estimated 15 million PCs in India, then it could result in consumption of 35.25 terra watts of power a year— which means a whopping 4,92,748,000 barrels of oil to produce that amount of energy. This is just one aspect of the energy crunch facing India. According to the Central Electricity Authority, at the current annual generation capacity of 1,35,000 MW, there’s a shortage of nearly 10% and it will only get worse. No wonder that the corporate sector is opting for intelligent power usage. Companies are designing innovative products and programmes to increase energy efficiency and cut costs.

INDIA INC STEPS IN
For example, IBM has integrated energy conservation into its environmental management system since 1974. Between 2000-2005, it reduced PFC emissions by 58% and made the technology available to others in the industry. In India, they launched Intelligent Energy Campaign last year and Project Big Green in June 2007. ‘‘The initiative includes new products and services for clients to sharply reduce data centre energy consumption, transforming the world’s business and public technology infrastructures into ‘green’ data centres,’’ says Reji Kumar Pillai, head, energy and utilities, IBM India. Statistics show IT data centres consume 15 times more energy per sq ft than a typical office building and, in some cases, may be 100 times more energy intensive. According to IDC, expenditure on power and cooling in data centres is growing at eight times the rate of expenditure on hardware. So ‘‘green teams’’ of energy efficiency specialists, as set up by IBM, is a step forward. Similarly, AMD India makes sure the PCs in its offices are switched off, screen savers are not used and ACs are fitted with thermostats that modulate temperatures. ‘‘The company also uses PowerNow in its server processors that helps reduce energy consumption of the server,’’ says Deepanshu Sharma, GM Marketing, AMD India.

GREEN GRID
In another initiative, a consortium of IT giants like AMD, Microsoft, Dell, Sun, IBM et al, have set up The Green Grid — a platform for IT professionals who aim to cut power consumption in data centres. It offers solutions and suggestions on the best practices available. ‘Green’ buildings is another concept fast gaining popularity. Commercial buildings are responsible for at least 40% of energy use in most countries. Industry estimates say ‘green’ buildings can save up to 50% energy, 35% of water usage and improve employee productivity by up to 10%. Adds Manoj Mathur, regional head, Trane India Ltd which helps make ‘green’ buildings, ‘‘Better usage of heat from the building can also be done. For example, in the process of cooling buildings, a lot of heat is wasted. This heat can be captured and used for a wide range of applications, like water heating etc.’’ The commonly-used incandescent bulb too wastes up to 95% of its energy on generating heat — only 5% goes into producing light. This at a time when the global demand for energy is expected to grow 53% by 2030 — 70% of this demand will come from China and India alone. S Venkataramani, head, lighting division, Philips Electronics India, says, ‘‘In India, 18,000 MW power is used for lighting purposes alone annually. A study done by MAIT-Emerson Network Power (India) on network power downtime reveals... India Inc could be losing over Rs 22,000 crore in direct losses due to poor power quality and operating environment related downtime. This is estimated to be around 2.2% of the gross output of the total industrial and service sectors.’’ Now, Philips India is in the process of creating an ‘‘ecosystem’’ comprising industry bodies, governments and NGOs and education institutes to break down the barriers against adoption of energy efficient lighting. It’s promoting compact fluorescent lamps (CFL) that save energy by 80%. ‘‘That’s a saving of Rs 500 and 84 kg of CO2 per lamp per year,’’ says Venkataramani. None of these initiatives will work unless there is collaboration by all concerned. As Pillai says, ‘‘For intelligent energy solutions to succeed, there must be a concerted and collaborative effort by industry, government and consumers; no company or organisation can do this alone.’’ Recognising this, the corporate world seems to have taken up the challenge of balancing both market needs and environmental priorities.

Around the world in solar taxi.

Louis Palmer dreamt of travelling around the world in a car when he was just 14. Twenty years later, his dream saw the light of day when he invented an ecofriendly car powered only by solar energy.
35-year old swiss is now on a promotional world tour in his solar car, demonstrating the sustainable technoogies are perfectly suited for everyday use, even to go around the world! "With this toud I want to show that solutions against global warming are available and that it can be stoppped"
Palmer says the many signs of global warming that he came across disturbed him. "The weather has changed so drastically in almost all the 60 countries I visited, that people are alarmed.
Developed by palmer with the help of students from four swiss technical universities over a period of one year, the solar taxi consists of a vehicle and trailer with solar cells - its 100% renewable energy with no polluting emissions. could be built for Approx 8000$ USD.

Talk while walk...charge your cellphone


Forgot to charge your phone before stepping out for a walk? Now you can walk the talk with an invention of four schoolchildren which allows you to charge your mobile phone with a contraption in your shoe! For that matter, the rudimentary contraption will come in handy, or leggy, outdoors while travelling, provided you have space to walk, according to the class XII science students of Vidya Bharti School at Bhatar in Surat.

The footwear, with springs in the heel that will propel a small wheel attached to a dynamo, will be able to generate enough electricity for charging your cell phone. The more you walk the more you can charge it, says Jinesh Chopra, one of the members of the team, which comprised Ipsa Agarwal, Vishwanath Patel and Nitish Jain. The team presented its device in the ‘Model Your Future’ section at Autofest ’07 held at Sardar Vallabhbhai National Institute of Technology last week. “The arrangement of different parts converts the linear force into rotational force, which can generate around five to six volts with each step. With constant power supply it is possible to charge a mobile fully within an hour,” says Ipsa.

Computers are wasting energy.

Of the $US250 billion spent per year on powering computers worldwide, only about 15% of that power is spent computing-the rest is wasted idling.

If the sheer, skyrocketing cost of electricity isn't enough to make you start looking to reduce your power bill, then maybe a reminder that electricity = fossil fuels burned = more carbon emissions = global warming will remind you that there's more than just a large electricity bill at stake here.

Here is computer power management tip



Youc can keeps your computer on for easy remote access and for nightly scheduled tasks (like backups and defrags), but didn't want to waste the energy an always-on computer would. Search for network setup that uses power-saving settings and Wake on LAN technology to get both energy efficiency AND constant availability. This estimates this new setup saves you almost $200 a year in energy bills and reduces your carbon emissions by 234lbs (!!). Here's how you i did it :

I used the open source DD-WRT firmware to set up a wireless bridge between my access point and my PC which is in another room. That allowed me to use Wake On LAN (WOL) to power up my computer remotely. I then changed the settings in my computer's BIOS and in Windows to allow WOL to start my computer from whatever state it was in. Lastly I used a BIOS setting to power my computer on every night at 3AM for scheduled maintenance tasks.
