Solar energy technologies were discovered by the ancient Greek society, yet we are still uncovering today how to store the sun's energy for use on those days when cloudy cover prevails and there is no sunshine to capture. Many alternative energy sources, such as solar energy, have been overshadowed, as well, by fuel sources such as coal and natural gas, once seen by early industrialists as abundant and seemingly limitless.

MIT's Chemistry Professor Dan Nocera and his research team offer society new hope for taking solar energy technologies one step closer to an in-home reality.

One of our KnowledgeBase writers, Robert Klar, otherwise known as Cowboy Bob, is a holidays enthusiast who would like to share some of his ideas about how to make the holidays an enjoyably green experience. He shares with us a few tips about LED lights that tie into the At Home article Christmas Light Safety. As for me, I greatly enjoyed walking through the Columbus Zoo's new LED Wildlights Display, sponsored this year by AEP with over 3 million brightly shining bulbs.

While we hope to inspire families to change out their traditional Christmas stings of lights with LED's this year, like Prince Charles has done for Buckingham Palace, the greater goal is to invoke a stronger, more broad use of the new LED technology in all light sources. After all, 6% of all electricity use in the U.S. comes from lighting sources. LED's are more than twice as efficient as compact fluorescents. So, look forward to watching how LED technology progresses in the coming years.

Happy Holidays!

Autodesk released a new online game called Retrofit Online Game for Green Buildings yesterday, intended to raise green awareness and be publicized through social media. Though China technically emits more CO2 than the U.S., we are still the leading country emitting CO2 per capita. No, of course we are not proud of our ranking?!

Check out the new game. Find out how much energy it takes to use a hair dryer and how much CO2 a typical American household outputs each day. It takes about 20 minutes to complete the video and quizzing portions. It is funny that you, the construction worker, have to work against a woman who is throwing her coffee mug at you, a man who is breaking windows as you work, and an annoying bird that throws you off the ladder.

Coldness as we know it may begin to change, no matter if global warming is a "natural fluctuation or an effect of industrial society's releasing heat-trapping gasses into the atmosphere," as reported in John Noble Wilford's New York Times article Ages Old Polar Icecap is Melting, Scientists Find, written nearly ten years ago. Scientists have proven the ice cap is melting in the summer at a greater pace and more aggressively than at any other recorded time in history.

National reporter Ted Anthony wrote "Analysis: Climate 'debate' pits loud vs. louder" yesterday for The Associated Press about the international debates encircling the climate change in Copenhagen. As experts present scientific data, the public pounds back with rebuttals via the UN's web portal called, "Add your voice to the Climate Petition." In short, Anthony suggests the experts' voices should take precedence over the general public's voice that is, in his opinion, based on information that is anything but scientific.

Maybe we should realize that we do not live in a world that is purely scientific? It would be naive to miss the fact that scientists do interpret data via their biased lens, just as easily as the "perceived uninformed public opinion" can validate natural occurrences with their own personal experiences.

Moving on, is it really worth it to debate now whether or not our planet is showing us signs of its weariness? Do we need to continue to justify our exorbitant use of natural resources? Even one little home / life change can help all of us to achieve the goal of "use less, waste less."

Human nature does not live on facts and data alone. We are passionate, compassionate, and are all capable of using our intuition to make advanced thoughtful conclusions, thus the difference between human and robot.

So, why not use all of our senses to wage a war on global change?

After all, that is what the famous architect Maya Lin did in her video about rainforest deforestation. Take a look.

Climate change is a topic that, unlike the polar ice caps, won’t be disappearing from the newspapers, televisions and websites that deliver our news. It’s no surprise then that the Copenhagen Climate Conference is the center of attention this week. As world leaders meet to debate the rate of climate change and the degree to which it should be controlled, design professionals continue to lead the way in implementing methods for reducing the effects of building construction and operation on our planet’s resources.
