Question: The driving force behind voluntary green electricity within the EU are the liberalized electricity markets and the RES Directive. According to the directive the EU Member States must ensure that the origin of electricity produced from renewables can be guaranteed and therefore a "guarantee of origin" must be issued (article 15). Environmental organisations are using the voluntary market to create new renewables and improving sustainability of the existing power production. In the US the main tool to track and stimulate voluntary actions is Green-e program managed by Center for Resource Solutions. In Europe the main voluntary tool used by the NGOs to promote sustainable electricity production is EKOenergy label.
Try to answer this question if possible: n the US, what is not the main tool to track and stimulate voluntary actions?
Answer: unanswerable
Question: Minute Maid Park (home of the Astros) and Toyota Center (home of the Rockets), are located in downtown Houston. Houston has the NFL's first retractable-roof stadium with natural grass, NRG Stadium (home of the Texans). Minute Maid Park is also a retractable-roof stadium. Toyota Center also has the largest screen for an indoor arena in the United States built to coincide with the arena's hosting of the 2013 NBA All-Star Game. BBVA Compass Stadium is a soccer-specific stadium for the Dynamo, the Texas Southern University football team, and Dash, located in East Downtown. In addition, NRG Astrodome was the first indoor stadium in the world, built in 1965. Other sports facilities include Hofheinz Pavilion (Houston Cougars basketball), Rice Stadium (Rice Owls football), and Reliant Arena. TDECU Stadium is where the University of Houston Houston Cougars football team plays. Houston has hosted several major sports events: the 1968, 1986 and 2004 Major League Baseball All-Star Games; the 1989, 2006 and 2013 NBA All-Star Games; Super Bowl VIII and Super Bowl XXXVIII, as well as hosting the 2005 World Series and 1981, 1986, 1994 and 1995 NBA Finals, winning the latter two. Super Bowl LI is currently slated to be hosted in NRG Stadium in 2017.
Try to answer this question if possible: What is the home of the Texans named?

Question: Ship transport is an important component of Melbourne's transport system. The Port of Melbourne is Australia's largest container and general cargo port and also its busiest. The port handled two million shipping containers in a 12-month period during 2007, making it one of the top five ports in the Southern Hemisphere. Station Pier on Port Phillip Bay is the main passenger ship terminal with cruise ships and the Spirit of Tasmania ferries which cross Bass Strait to Tasmania docking there. Ferries and water taxis run from berths along the Yarra River as far upstream as South Yarra and across Port Phillip Bay.
Try to answer this question if possible: Which is Australia's busiest port?
Answer: The Port of Melbourne
Question: In October 1745, Ewald Georg von Kleist of Pomerania, Germany, found that charge could be stored by connecting a high-voltage electrostatic generator by a wire to a volume of water in a hand-held glass jar. Von Kleist's hand and the water acted as conductors, and the jar as a dielectric (although details of the mechanism were incorrectly identified at the time). Von Kleist found that touching the wire resulted in a powerful spark, much more painful than that obtained from an electrostatic machine. The following year, the Dutch physicist Pieter van Musschenbroek invented a similar capacitor, which was named the Leyden jar, after the University of Leiden where he worked. He also was impressed by the power of the shock he received, writing, "I would not take a second shock for the kingdom of France."
Try to answer this question if possible: Besides the scientist's hand, what other component of the experiment in which the basic properties of capacitors were discovered acted as the second conductor?
Answer:
the water acted as conductors
