Where are America's Greenest Buildings?
July 16, 2014 04:59 PM - Elisa Wood, Clean Techies
Ok, no surprise to see Washington, D.C. or San Francisco ranked high in a list of the cities with America's greenest buildings. But Atlanta? Georgia's capital was the only southern state to make the top ten in the 2014 U.S. Clean Tech Leadership Index, released July 15 by Clean Edge. The cleantech research firm tracks the cleantech progress of the 50 largest metro areas and the 50 states.
Why can't we recover precious metals from landfills?
June 30, 2014 08:17 AM - CleanTechies, Clean Techies
Mining for precious metals like gold, silver, and copper is extremely costly. Not only does it require a huge amount of energy and have a devastating impact on the environment, it also puts human life at risk. Still, these metals are what enable our precious smartphones and tablets to work so efficiently, so we have to get them from somewhere. But what if that somewhere was old gadgets we no longer want instead of deep within the Earth?
¿Será un coche eléctrico apto para sus necesidades?
May 6, 2014 04:57 PM - CLEANTECHIES GUEST AUTHOR, Clean Techies, Clean Techies
Operar un coche sin necesidad de visitar una gasolinera es una idea intrigante para muchos conductores estadounidenses. Después de todo, las gasolineras pueden ser un lugar difícil, considerando los altibajos de los precios de la gasolina en los últimos años. Pero en la mente de muchos estadounidenses los coches eléctricos no son más que coches de golf glorificados incapaces de proporcionar el manejo diario adecuado o suficiente velocidad para su uso en autopista. En esta nueva era del transporte electrificado, esos conceptos erróneos deben ser dejados atrás.

Is an Electric Car Right for You?
May 3, 2014 09:52 AM - CLEANTECHIES GUEST AUTHOR, Clean Techies
Operating a car without needing to visit a gas station is intriguing idea to many American drivers. After all, the pumps can be a painful place—gas prices have been on a roller coaster ride the past few years. But in the minds of many American, electric cars are nothing more than glorified golf cars incapable of providing adequate daily driving range or sufficient highway speed. In this new era of electrified transportation, those misconceptions need to be tossed aside. Todays' electric vehicles, like the Nissan Leaf, provide all the creature comforts and capabilities of gasoline internal combustion cars. These EVs comfortably seat four or five passengers, offer quasi-luxury features, and serve up smooth, silent and sporty levels of acceleration. But there are a couple of important issues to consider—such as driving range and refueling times.

Hydrogen Cars to Hit the Road This Spring
February 14, 2014 12:22 PM - CleanTechies Guest Author, Clean Techies
Although electric and plug-in hybrid vehicles have been considered the only plausible alternatives to conventional cars for a long time, and practically all of the world’s biggest car makers have been investing heavily in these technologies, and governments around the world have been trying to promote the use of such vehicles by offering generous incentives and financial benefits to those who choose to buy an alternative fuel vehicle instead of a gasoline-powered car, adoption has been lagging and sales have not been as strong as the auto industry had expected.

Renewables Now Cheaper Than Fossil Fuels in Australia
January 8, 2014 07:35 AM - Celsias, Clean Techies
A study by Bloomberg New Energy Finance (BNEF) in Australia has discovered that renewable energy is cheaper to produce than the old conventional fossil fuel sources, and that is without the subsidies. The study shows that electricity can be supplied from a new wind farm at a cost of AUD 80/MWh (USD 83), compared to AUD 143/MWh from a new coal plant or AUD 116/MWh from a new baseload gas plant, including the cost of emissions under the Gillard government’s carbon pricing scheme. However even without a carbon price (the most efficient way to reduce economy-wide emissions) wind energy is 14% cheaper than new coal and 18% cheaper than new gas.
2014 National Defense Authorization Act is huge win for LEED green building system
January 3, 2014 09:15 AM - Stuart Kaplow, courtesy Green Building Law Update, Clean Techies
President Obama signed the National Defense Authorization Act for fiscal 2014 in Honolulu last Thursday and while most observers noted that the bill cracks down on sexual assaults in the military and eases restrictions on transferring detainees from Guantanamo Bay, the bill also is a huge win for the U.S. Green Building Council's LEED green building rating system. By way of background, the Air Force, Army, Marines, Navy and other instruments of the Department of Defense own and operate 299,000 buildings and 211,000 additional structures, making it the largest owner of buildings in North America, but it is also the owner of more green buildings and more LEED certified buildings than anyone else.
