he how ld
characterize the energy situa
ation right now in this country? Would you
say that:

We are doing well 4 5
We are doing okay 17 19
We are having some problem ms 29 34
We are on the verge of a cris
sis 28 28
We are in an energy crisis 21 13
COMMENT: Voters see the ene ergy problem more negatively than they did two
years ago, but not by large mar
rgins. Doing “well” and “okay” combined has
declined from 24% to 21% and “verge of a crisis” combined with “in an energy
crisis” has increased from 41% to 49%. All responses of a negative nature total
%
78% indicating that Americans believe that the energy situation is a problem of one
degree or another.

51. Conserve Water
“The reality is that, over the 30-
-year life of a typical
home mortgage, there is a 26% chance of a flood that exceeds
mortgage
the 100-year standard. Over the course of a century, there is a
63% chance that a flood greater than the 100-year standard will
strike, a 26% chance of two such floods, and an 8% chance of
h
three such floods. So it is hardly a statistical surprise that the

against river floods to a 2,000-year standard for
densely populated areas and a 200-year standard
for rural zones.

surface and you get 2 terawatts

Then he turned to the sun, his research focus, which
bathes the planet in 800 teraw watts of energy continually.
“We only need 18 of those terawatts,” he said. But the

• To earn the ENERGY S STAR, a home must meet
guidelines for energy effficiency set by the U.S.

Environmental Protectio Agency. These homes

are at least 15% more e energy efficient than
homes built to the 2004 International Residential

Code (IRC), and include additional energy-
