Renewable Energy at $254 Billion? Let's Make It a Clean Trillion

Billionaire bankers gathered at the United Nations yesterday to call for more investment in renewable energy -- $1 trillion a year, to be exact.
 
It won’t be easy. Global investment in renewable energy fell 12 percent in 2013 to $254 billion, according to data released by Bloomberg New Energy Finance (BNEF), casting a shadow over the notion of a “clean trillion.”
 
Last year was the second decline in renewable investments since 2011’s record-high $318 billion. Investors and climate-policy advocates including hedge-fund billionaire Tom Steyer and former U.S. Treasury Secretary Robert Rubin called for changes to financial markets that would boost investment. Financing must double by 2020 and double again to $1 trillion by 2030 in order to avoid global warming of more than 2 degrees Celsius, reports Ceres, the host of yesterday's conference.
 
These top-line numbers are fuzzy and paint a picture that’s perhaps more bleak than reality. First, the price of solar energy continues to tumble, so more renewable energy is being generated with fewer dollars invested. Second, while BNEF’s clean-energy tally is the most comprehensive for renewable energy, it’s not all-encompassing; it doesn’t include most energy-efficiency measures, fuel-efficiency gains or expanded public transportation.

WS510 Secondary Standard

In the monitoring of large photovoltaic (Utility Scale), in assessing potential sites (Solar-assessment), or in up and coming electricity cost saving initiatives projects (Commercial & Industrial), the WS510 now provides the market a secondary standard pyranometer, ultrasonic wind speed, ultrasonic wind direction, temperature, pressure and humidity all in a single unit.. This sensor meets the high demands of the world meteorological organization (WMO) through the active valving at air temperature measurement and the inertia- and maintenance-free measurement of wind speed and wind direction on the ultrasonic principle. Equipped with a Kipp & Zonen pyranometer of the secondary standards, the WS510-UMB Compact weather sensor from Lufft unites the precision of a variety of meteorological individual sensors in a single all-in-one device, for the first time.
