Hari Bumi Sedunia 2012

Sekali ku memandang kehijauan saujana mata
Semusim yang benderang hati riang nikmatnya Tuhan
Kita belalah bersama-sama
Kita jagalah harmoninya

Semusim ia datang keindahan ciptaan Tuhan
Hijau yang terbentangan makhluk Tuhan bermesra-mesra
Kita belalah bersama-sama
Kita jagalah harmoninya

Damai terperi kicau bernyanyi
Burung berkicauan riang terbang
Ombak menghempas pantai menanti
Indah biru laut ini pasti

Salam diberi insan di bumi
Itu nikmat hari hari ini
Tegur dan sapa senyum ketawa
Itu tanda kita riang ria
Abadikan keindahan ini



(Semoga kita pelihara Bumi ini daripada kerosakan yang dilakukan oleh manusia sendiri)

Save power, save money: 6 easy tips to reduce your electricity usage and bills

• by Emily Hsieh, Shine staff, on Wed Mar 31, 2010 10:00am PDT

There are a bunch of little tricks you can employ to cut back on power consumption at home—which not only has environmental benefits but keeps you from wasting cash too—and it's highly unlikely you'll even notice a difference. Between the National Resources Defense Council's site and powerscorecard.org I found some really good tips. Here's a re-cap of six simple, painless ways to cut back:

1. Check this: refrigerators suck up a whopping 20% of your household electricity use. Time to turn them down! Aim for somewhere between 38-42 degrees in the fridge, and 0-5 degrees in the freezer. If you've got an energy saver switch, make sure it's flipped on. Doors should be sealed tight: to test, stick a dollar bill between the gaskets and close the fridge door; if the bill is hard to pull out you're in good shape. If not, it's time to replace the gaskets.

2. Wash only full loads in your dishwasher (yet another reason to learn to pack them efficiently!), and if you have time, let them air dry by turning off the drying cycle manually—this can save 20% of your dishwasher's total electricity usage.

3. Don't use hot water when doing the laundry. If you must, try warm water, though in most cases cold is probably just fine. Make sure that the amount of water you're using corresponds with the size of your laundry load.

4. Lower the temperature of your water thermostat to 120-130 degrees (any lower than that might backfire on you, since you might end up running out of hot water).

5. Clean your air filters regularly. Air conditioners have to work a lot harder to circulate air through filthy filters, which is a totally unnecessary electricity drain.

6. And while you're sitting in front of the computer, turn on the sleep mode, so it's less of a power drain when you're not using it. Windows users can do this via the control panel, while Mac users can find energy saving settings under system preferences in the apple menu.
