Red Rock Hydroelectric Project: Successfully Generating
New Power from a Pre-Existing Dam
There is plenty of potential for the U.S. to increase its hydropower output,
though much of that would involve retrofitting existing dams to produce electricity.
Done right, as in the case of a project in Iowa, such projects can add to
the country's growth in renewable energy.

Sun Shines on FPL's Solar Program
Florida Power & Light (FPL) continues to roll out a plan to bring solar power to
millions of the state's residents, a strategy designed to provide clean electricity
to businesses and homeowners. The utility's solar energy centers are putting
power from the sun at the forefront of FPL's generation portfolio.
Winds of Change Revitalize West Texas
Texas has long been known for its abundant energy resources, but today wind
energy is garnering much of the attention that used to go to the state's oil and
gas industry. The High Lonesome Wind Farm, a project located near McCamey,
a town some folks refer to as " The Wind Energy Capital of Texas, " shows how
renewable resources can create new opportunities for old oil boomtowns.
A Big Splash for Marine Power: Minesto's Underwater Kite
Minesto's marine energy technology, called Deep Green, generates electricity
from low-flow tidal streams and ocean currents through a unique process
similar to a stunt kite flying in the wind. The wing pushes the turbine through
the water in a figure-eight-shaped trajectory, sweeping a large area at a relative
speed that is several times the actual speed of the underwater current.

Minesto's DG100 marine power plant,
known as a " tidal kite, " consists of a
wing, which carries a turbine (shown on
the cover) directly coupled to a generator
in the nacelle. Rudders and a control
system steer the kite in a predetermined
trajectory, while struts are tethered to a
bottom joint at the seabed foundation.
