“Take Away” Coffee or Tea Lovers

Bring tumbler to your favorite coffee or tea shop, if you want to have “take away drink”, because using tumbler reduces the amount of waste heading to landfills. It decreases the amount of pollutants that end up in water. The water that nourishes coffee or tea plants. That ends up as coffee or tea in your tumbler.

Don’t Use Google

Start using Blackle as your default search engine.

Why?

Blackle saves energy because the screen is predominantly black. “Image displayed is primarily a function of the user’s color settings and desktop graphics, as well as the color and size of open application windows; a given monitor requires more power to display a white (or light) screen than a black (or dark) screen.” Roberson et al, 2002

In January 2007 a blog post titled Black Google Would Save 750 Megawatt-hours a Year proposed the theory that a black version of the Google search engine would save a fair bit of energy due to the popularity of the search engine. Since then there has been skepticism about the significance of the energy savings that can be achieved and the cost in terms of readability of black web pages.

Believe that there is value in the concept because even if the energy savings are small, they all add up. Secondly, Seeing Blackle every time we load our web browser reminds us that we need to keep taking small steps to save energy.

Trees Againts Global Warming

Trees are important tools in the fight to stave off global warming, because they absorb and store the key greenhouse gas emitted by our cars and power plants, carbon dioxide (CO2), before it has a chance to reach the upper atmosphere where it can help trap heat around the Earth’s surface.

One of many actions to reduce global warming is plant trees when you travel,

  • 1 tree every 2,000 miles (3200 km) by car.
  • 1 tree every 1300 miles (2000 km) by plane.
  • 1 tree every 100 gallons (375 liters) of gasoline.
  • 1 tree every 1000 kilowatt-hours (one kwhr ~= 1.9 pounds CO2).

Compact Fluorescent Bulb

Use 75% less energy than incandescent bulbs and last up to 10 times longer.

It would reduce greenhouse gas emissions by the equivalent of more than 20,000 cars. If every home in the country did the same, it would be like ditching 800,000 cars and would save enough energy to light more than 2.5 million homes for a year.

So… change your light bulbs.

One person, making the choice to get involved.

One store, pitching in to help the neighborhood.

One company, staying true to its values.

One world that gets a little better for everyone.
