Cet-4-1.17-Exercise 01“Mass adoption of the Internet is driving one of the most exciting social, cultural, and political transformations in history, and unlike earlier periods of change, this time the effects are fully global.” Schmidt and Cohen write in their new book, The New Digital Age. How do Schmidt and Cohen describe the effects of the Internet?
Cet-4-1.17-Exercise 02Aside from the panels on the roof, Premier Gardens looks like a community of conventional homes. But inside, special windows cut power bills by blocking solar heat in the summer and retaining indoor warmth in winter. The rest of the energy savings comes from the solar units. They don’t just feed the home they serve. If they generate more power than the home is using, the excess flows into the utility’s power grid. The residents are billed by “net metering”: they pay for the amount of power they tap off the grid, less the kilowatts they feed into it. If a home generates more power than it uses, the bill is zero. How are the residents in the ZEH communities billed for electricity use?
