Slide Library
At the National Renewable Energy Laboratory, our analysts frequently convert their research into information that is presented to other professionals, as well as the general public. Some of our more significant presentation slides are featured on the home page of the Web site, but also are referenced here in our Slide Library for future use.
Utility Green Pricing Activities
Since the first utility green pricing program was offered in 1993, more than 600 utilities in 34 states now offer green pricing. At the end of 2004, more than 700 MW of new renewable energy capacity has been installed to meet utility customer demand with another nearly 230 MW announced or already under construction. Nevertheless, only about 20% of the nation's utilities currently offer green pricing so there is plenty of opportunity for growth. For more on this topic, visit the Green Power Network.
Personal Travel
Do human beings have an inclination to devote a fixed amount of time to travel on an average daily basis? This slide indicates that the average daily time spent traveling has been fairly constant in several different countries and different years, even though the average daily distance has been quite variable. In the third column, the slide also suggests that the percent of disposable income allocated to travel costs is somewhat, but not strongly, correlated with distances traveled.
