Light bulbs are synonymous with bright ideas — in cartoons, at any rate. But compact fluorescent bulbs can also be a small, yet brilliant, step toward energy efficiency. The Energy Department says they use 66 percent less energy than incandescent bulbs and last 10 times longer.
· Why buy: Compact fluorescent bulbs (CFLs) are available in different sizes and shapes, including mini-spiral, spiral and A-line, that fit almost any fixture. On average, each bulb can save... Read Full Story
Green cards or Climate cards as they are more commonly known are the new big thing for the credit card industry. These cards act just like regular credit cards, but your purchases help the environment in some way. The newest contender is the Brighter Planet Visa credit card with EarthSmart points. You earn 1 EarthSmart point per dollar spent in net retail purchases. You can now earn 50% more points with a match by Bank of America through December of 2008. You can also earn up to 2000 bonus...

The incandescent light bulb, one of the most venerable inventions of its era but deemed too inefficient for our own, will be phased off the U.S. market beginning in 2012 under the new energy law just approved by Congress. Although this will reduce electricity costs and minimize new bulb purchases in every household in America, you may be feeling in the dark... Read Full Story
Home energy conservation tips can help towards having a more energy efficient home. An energy efficient home is something we should all strive for. Not only can small steps be taken to lighten the footprints we leave behind fo... Read Full Story
The more and more that I read the news from around the world, the more evident it is that alternative energy is catching on everywhere. However, can it continue to keep making ground where it counts? That is to say, is the interest big enough to gather the needed consumer dollars and make it worthwhile to the corporations out there? One would think that with the high oil prices that posted this week that clean energy would be in the forefront. However, Nick Perry noted that this is not... Read Full Story
Last year, I acquired 4 new energy conservation toys which we wrote many articles on with of course pictures, specifically:
Solar Charged Electric Lawn Mower
Exterior Solar Shades
Retractable Screens
Solar Air Heater
Each of them helped to reduce the direct and indirect consumption of non-renewable energy resources in our home, reduce the amount of greenhouse gas emissions generated in and around our home, and reduced to varying degrees our electric, home... Read Full Story
TreeHugger has a detailed guide to the compact fluorescent light bulb, telling you everything you’d ever wanted to know about them.
* Energy use: 60-80% less than incandescents
* Lifespan: 6,000-15,000 hours (6-15x longer)
* Cost savings: up to $30 over its lifespan
And much, much more, all here:
One of the most contentious points about widespread use of CFLs [...] Read Full Story
So what happens to people who lose their country to war or nature like Spiegel is reporting about Tuvalu. If the islands disappear, they can go join another state and replace their passports, like with Australia. But we are talking only few people here. Think about Bangladesh, whose 75% land area is only 6 feet above sea level. If the sea levels rise, then? Where will all those hundreds of millions of people go? What will they do?
But I was a bit of a ruminative mood. Its like languages... Read Full Story
Australia plans to phase out incandescent bulbs by 2010 in efforts to become the world’s first national government to phase out incandescent light bulbs in favor for the energy efficient compact fluorescent bulbs (CFLs) which use about 80% less electricity to produce the same amount of light.
By removing incandescents by 2010, Australia is hoping to remove four million metric tons a year by 2015. The minister, Malcolm Turnbull is urging other nations to follow suit in banning traditional... Read Full Story
2008 Conference Paper Synopsis: The source of the wind is the sun. The winds come from the suns energy falling on the earth’s surface, giving rise to heating of the atmosphere.   This leads to convection currents in the atmosphere, ie the movement of air due to changes in its density and pressure. We can gain an understanding of how global circulation works by developing simplified models of the processes that produce the global system. The physical drivers of the wind at a global scale...
