While it does take energy to make the ice, much more energy is saved using this method vs standard air conditioning. The article states that one building, Credit Suisse, is saving 2.15 million kilowatt-hours annually, which at current power prices would be over $300,000 in savings annually. The actual savings may be much higher than my calculation since the ice is made during off-peak hours, and the energy is saved during peak hours.

From what I hear the flashlights are also very well designed and work really well. It fits nicely in the hand, and also lights up a wider area than typical flashlights.

Here's a clip from the BlogLight Blog:

We have started passing out our traveling BoGo lights - the light has a tag which explains the program, and then asks the recipient to use it for a couple of days, then pass it on to a friend. Each light is numbered and has a code, so people will shortly be able to log on and provide their generic location and their comments.

We have created a page of solar powered lighting products that you can browse through.

Energy Innovation will feature an exhibit hall where companies offering energy conservation-related products and services will display their latest innovations to the more than 500 attendees that are expected at the convention.

These mowers can be hard to find, since your local hardware store would probably rather have you buy more expensive mowers, but you can buy them online.

Today Nokia announced that all of their new devices will alert users to unplug the charger once the battery is full.

Mobile phones sounding a beep and displaying an alert -- "Battery is full, please unplug the charger" -- could save enough electricity to power 85,000 homes annually, Nokia said.

Curious to know just how much energy will be saved each year by the new day light savings time law change of 2007? We certainly were, so here's our back of the napkin calculation.

To calculate this estimate we will assume that every person in the US will be running one 60W light bulb for one extra hour for 21 extra days (since that's how many days it was moved up).

The population of the united states is 298,444,215 (according to the CIA July, 06). Multiply that by 60 watts, and then by 21 days. Now divide that result by 1000 to convert it from watt hours to kilowatt hours (which is how you pay for energy).

The amount of energy saved by the new law is 376,039,711 KWh each year.

I realize that kilowatt hours don't mean much to most folks so let's convert that into dollars. Using the average price of electricity in the US 10.6 cents / kilowatthour, that is a savings of $39,860,209.40.

Here's how you can qualify for the Residential Energy Credits:

• Install Energy Star Exterior Windows - deduct 10% up to the total cost, up to $200.
• Install Energy Star Exterior Doors - deduct 10% up to the total cost, up to $500.
• Install Energy Star Central Air, Heat Pump, or Water Heaters - up to $300 of the total cost including installation.
• Install a new Furnace or Boiler - deduct up to $150

Be sure to check with the product manufacturer (by phone or web site) to see if a product qualifies for the Home Energy Efficiency Improvement federal tax credit. And remember to consult with your Accountant or Tax Preparer as well.

Let's just look at cell phones, of which there are an estimated 190 million in the United States. A quick back of the envelope calculation says that the combined stand-by usage of all those cell phone chargers, each drawing a measly watt, could add up to 190 megawatts per day. That's enough to power approximately 100,000 homes.
