1.
1 point
A pipe leading to the turbine which supplies water.
2.
1 point
A ________ allows incoming flood tide to pass into an inlet - a one way gate.
3.
1 point
Most of the geothermal activity occurs here--around the Pacific Ocean.
4.
1 point
There are about 78 million kilowatts of hydro generating capacity in the United States. That is equivalent to the generating capacity of 80 large nuclear power plants.
5.
1 point
The matter lost during nuclear fusion on the sun is emitted into space as radiant energy.
6.
1 point
Solar energy is non-renewable.
7.
1 point
A low dam that is built across an ocean inlet - used for tidal energy.
8.
1 point
Tidal Energy, wave energy, and ocean thermal energy conversion are other hydro resources.
9.
1 point
The sun radiates more energy in one second than people have used since the beginning of time.
10.
1 point
Power from water.
11.
1 point
Hybrid Solar Systems combine passive solar and active solar to collect the suns energy.
12.
1 point
In the 1940’s hydropower provided 33% of the country’s electricity, now it provides almost 6% in 2011.
13.
1 point
For wind turbines to be most efficient, the winds must blow at least 13 miles per hour.
14.
1 point
Operating and maintenance costs for geothermal power plants are higher than coal-fired and natural gas plants.
15.
1 point
One of the reasons that electricity from hydroelectric has decreased is because of the drought in the western states.
16.
1 point
Passive solar houses are built with their windows facing south, so sunlight can enter into the house.
17.
1 point
One advantage of a geothermal exchange system is that it doesn't have to manufacture heat. The heat is free, renewable, and readily available in the ground.
18.
1 point
If turbines are too close together they block each other’s wind.
19.
1 point
As people discovered centuries ago, the flow of water represents a huge
supply of ______________ that can be put to work.
20.
1 point
Generating electricity with hydropower is the most expensive way to generate electricity in the U.S. because the fuel supply (water) is never available.
21.
1 point
Photovoltaic cells (PV) convert only about 10 to 20 percent of the radiant energy into electricity - fossil fuels convert from 30 to 40 percent of their energy into electricity.
22.
1 point
Wind is caused by the sun - the uneven heating of different surfaces on the earth.
23.
1 point
The hydrogen atoms in the sun’s core combine to form helium and generate energy in a process called nuclear fusion.
24.
1 point
A _________ uses the Earth’s constant temperatures to heat and cool buildings.
25.
1 point
Development of geothermal power plants is often allowed on federal lands because it does not significantly harm the environment.
26.
1 point
Geothermal power plants use _______________ to clean the air of hydrogen sulfide and other gases.
27.
1 point
Each wind machine requires about 1 square mile of land.
28.
1 point
The distance from the highest level of the dammed water to the point where it goes through the turbine - the height of the water.
29.
1 point
Many ancient peoples, including the Romans, Chinese, and Native Americans, used hot mineral springs for bathing, cooking, and heating.
30.
1 point
One of the biggest advantages to hydropower is its ability to store energy - water (energy) can be stored in a reservoir to be used at high demand periods.
31.
1 point
The cost per kilowatt-hour to produce electricity from PV cells is currently three to four times as expensive as other conventional sources.
32.
1 point
How much water moves through the system.
33.
1 point
As long as the water cycle continues, we won’t run out of hydropower so it is considered a renewable energy source.
34.
1 point
Solar can be used to heat homes but can not produce electricity.
35.
1 point
Most geothermal power plants are flash steam plants.
36.
1 point
Utility companies are required to purchase electricity from independent power producers at rates that are fair.
37.
1 point
When energy is produced from the temperature differences between deep water and shallow water.
38.
1 point
About 15 percent of the sun’s energy that hits the earth is reflected back into space, about 30 percent evaporate water, some solar is absorbed by plants, land, and oceans, and the rest is used for sun tanning.
39.
1 point
Only one part in two billion of the energy radiated by the sun into space strikes the earth.
40.
1 point
Geothermal systems are low maintenance and should last half as long as conventional systems.
41.
1 point
Many wind farms are owned by private business people who sell the electricity to electric utility companies.
42.
1 point
An artificial lake - like Flaming Gorge is a _____________.
43.
1 point
The process where the slabs of the continents and ocean floor drift apart and push against each other - about 1 inch per year.
44.
1 point
The first hydroelectric plant was Niagara Falls.
45.
1 point
Active solar homes use equipment like pumps and blowers and an outside source of energy like a solar collectors to heat the house.
46.
1 point
Just like coal, oil, and nuclear power plants, hydropower plants produce heat to spin a turbine.
47.
1 point
_________________ are used to release excess water.
48.
1 point
The earth’s interior is made up of the ____________
49.
1 point
Because we have the sun, wind is a renewable energy source.
