Clemson University uses energy from different sources. What are the primary types of energy source?
Electricity and natural gas
Combined cycle generation of electricity can
boost efficiency to 50% or greater
occurs where a central facility distributes heat to other locations within its 'district', thus making the use of heat that otherwise might be wasted
Geothermal energy applications
include direct space heating, electric generation, and as a heat pump source/sink
Geothermal energy can affect the environment
By ejecting 'waste' heat and potentially causing earthquakes.
In Iceland, geothermal energy is used for:
electric generation, space heating, melting snow on roads and sidewalks, swimming pools, greenhouses

Dams can be constructed to serve many purposes including navigation, and flood control in addition to hydropower.
Hydroelectric power provides approximately _____ percent of the electrical energy needs for the world.
Hydroelectricity is well-suited
for peak load power demands due to the ability to start and stop quickly
Hydropower is an example of non-renewable energy because of the short lifespan of dams.
Hydropower is essentially a type of
any and all of the above
Of the four fundamental forces of nature, hydroelectric power employs the _______________________ during the process of precipitation in the watershed and the __________ during the water motion to turn the turbines and finally the ________________________ is transmitted over the electric grid so that you can make toast.
electromagnetic force, force of gravity, electromagnetic force
One of the largest hydroelectric generating facilities on earth is located on the _________ River in China and the dam is called the ___________.
Yangtze River, Three Gorges Dam
pumps water upstream during off-peak demand
Environmental impacts from hydroelectric power production may include:
Low temperatures downstream from dams
Low dissolved oxygen concentrations in outflows
Sediment and nutrient removal from impounded streams
Blocking migrations of aquatic organisms
Long-term alteration of stream channels and stream flows
The energy to pump water upstream during pumped storage
is dependent on the price and availability of the energy
will always have the same number of protons no matter what the atomic mass

Nuclear accidents include
the Fukushima disaster, Chernobyl, Three Mile Island
Nuclear power generates approximately ___________ of electricity in the USA and approximately ________ in France.
Nuclear power is best suited for
generating base load electricity
Oconee Nuclear Station generates over 8000 megawatts when it is at full capacity. Approximately 2400 megawatts is converted to electricity. The remainder of this energy
