    The shoe, set for release Feb. 1, retails for $190. Rickie Fowler, Jonas Blixt, Will MacKenzie and Jesper Parnevik are among the pro golfers set to wear it.

    IRENA to launch 'Google of renewable energy'

    Ben Welter - Tuesday, January 13, 2015

    CleanTechnica's Zachary Shahan reports that the International Renewable Energy Agency is ready to unveil REsource, a research tool he describes as "akin to a Google of renewable energy." 

    IRENA says the goal is to provide "relevant, reliable and timely information on renewable energy market statistics, potentials, policies, finance, technology costs and benefits, innovations and education."  Screenshots of the tool show a Google-like main screen that will allow visitors to tap IRENA's "vast knowledge base" for information by source, energy type and country.  

    The tool is expected to be launched at IRENA's 5th Assembly in Abu Dhabi next week.

    High growth in PCM demand seen for shipping, transportation, textiles, electronics

    Ben Welter - Tuesday, January 13, 2015

    Companies and Markets is projecting that demand for advanced phase change material will reach $1.4 billion by 2019. Europe will remain the largest market, followed by the Americas. 

    "Building & construction is the major application for the advanced PCM market," the report said. "It accounted for 20% of the market share in terms of volume, in 2013. Shipping, packaging & transportation, textiles, and electronic applications of advanced PCM are projected to experience high growth among the applications between 2014 and 2019."

    20% CAGR projected for advanced PCMs

    Ben Welter - Wednesday, January 07, 2015

    The global market for advanced PCMs is projected to reach $1.47 billion by 2019, according to ReportsnReports.com. That's a compound annual growth rate of more than 20 percent over the next five years. The market for thermal energy storage PCMs is projected to register a CAGR of 22 percent in that period.

    "Organic PCM are projected to have the higher growth rate than inorganic PCM due to the higher prices and ease of microencapsulation for organic PCM," according to the report.

    10 strategies for sustainable lab design

    Ben Welter - Tuesday, January 06, 2015

    Blake Jackson and Stephen Palumbo of Tsoi/Kobus and Associates and Jacob Knowles of BR+A Consulting Engineers offer "10 practical strategies to help guide decision-making to further elevate sustainable laboratory design, regarding resource utilization, carbon footprint and long-term viability." Strategy No. 1: Reduce lighting power densities. The authors note that building codes are lowering LPD thresholds, thanks to the availability of cheaper and more energy-efficient LEDs for ambient and task lighting.
