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

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.

December 24, 2013 12:16 PM - Green Building Law Update via, Clean Techies

Earlier this month, while few people were watching, the 20,000th LEED commercial project was certified! Wow. In the event you missed the huge happening on December 4th, it is a LEED 2009 Commercial Interior Certified project in Knoxville, Tennessee. This green tenant improvement portends enormous business opportunities associated with the U.S. Green Building Council and the existing built environment.

The Unintended Consequences of Reflective Pavements
December 11, 2013 12:53 PM - CleanTechies Guest Author, Clean Techies

Among the most interesting exhibitors at the recent Greenbuild International Conference and Expo in Philadelphia may have been the Asphalt Pavement Alliance challenging what we thought we knew about urban heat island effect with new research from Arizona State University.

Pollution-Free Boating
December 3, 2013 06:48 AM - Andy Wallace, Clean Techies

The Chevrolet Volt, Nissan Leaf and Ford C-Max Energi are the top three electric vehicles on the roadways, but what about our waterways? Electric cars aren’t the only vehicles transforming sustainable and economical transportation. Electric boats are also traversing historic waterways and canals that have been polluted with oil and noise. Electric boats may be the only watercraft permitted on municipal waters by 2020, and New Electric is already influencing the electric vehicles industry as an electric-conversion business dedicated to battery-powered boats. About 700 million gallons of oil pollute oceans every year, according to Clean Technica. Engine-exhaust from conventional boats and ships only worsens the harmful environmental effects. Not only is the ocean and air polluted, marine animals suffer from intense noise pollution. Watercraft are actually detrimental to sea life, such as orcas and dolphins, because of their sensitivity to loud sounds. Electric-converted watercraft are quieter and produce no air pollution.

Does Biodiesel Suffer From Ethanol’s Bad Rap?
November 19, 2013 08:10 AM - CleanTechies Guest Author, Clean Techies

Biodiesel and ethanol both fall under the category of "biofuels," which describes any fuel synthesized from plant or animal matter. But that’s pretty much where the similarities end.

LEED certification tax credit eligibility deadline fast approaching
November 11, 2013 02:22 PM - Guest contributed , Clean Techies

With construction projects facing deadlines to be eligible for tax credits, drop dead dates to meet contractual obligations and otherwise needing to obtain LEED certification by December 31st, submission deadlines to the Green Building Certification Institute are fast approaching. Appreciate that a couple of weeks ago (i.e., the week that ended November 2nd) 48 projects comprising 8,833,676 square feet achieved LEED certification in the U.S. (not including Homes or the several 'confidential' projects that were certified).

Green Building is Now the Law in Dallas
October 23, 2013 09:45 AM - Stuart Kaplow, courtesy Green Building Law Update via, Clean Techies

Dallas has now accepted the first building permit applications under its green building ordinance. Dallas is one of the first major cities in the nation to implement comprehensive mandatory green building standards for both all new residential and commercial construction. By Resolution 08-1070 adopted unanimously on April 9, 2008 Phase 1 of the law was effective in 2009 and Phase 2 (originally to be effective October 1, 2011) was fully implemented October 1, 2013.

Time to standardize EV charging in America
October 12, 2013 07:34 AM - Brad Berman, Clean Techies

Hard data collected from plug-in vehicle owners shows that the majority of EV charging takes place at home. Still, the ability to charge an electric car along the road—even if infrequent—can extend the distance each car can travel over the course of a day. Unfortunately, the public charging landscape is littered with complications and inconveniences brought on by multiple standards and incompatibilities between different vehicles and charge providers. Imagine if each brand of gas station required its own subscription, and each brand of car was compatible only with a certain type of gas nozzle.

European Union on Track to Reach 2020 Climate Goals
October 10, 2013 08:52 AM - Edouard Stenger, Clean Techies

According to the European Environment Agency, the European Union is already close to its 2020 climate objectives as it has decreased its emissions by no less than 18 percent between 1990 and 2012. Additionally, renewable energy sources such as wind, solar and many others were already accounting for 13 percent of the energy mix in 2011. The European Union have a comprehensive energy and climate plan as it has three objectives: 1. to slash its greenhouses gases emissions by 20 percent from 1990 to 2020 ; 2. to increase its energy efficiency by 20 percent ; 3. to increase its share of renewable energy sources to 20 percent of the mix by 2020.
