Geothermal Energy Resource and Hydroelectric Power Resource

Question 1

the presence of geologic features such as volcanoes and fumaroles, hot springs, and geysers makes ________ possible

Answer 1

geothermal energy resource

Question 2

What are the factors that affects the hydroelectric power?

Answer 2

Volume (density) and steepness of the slope (gravity)

Question 3

What is geothermal energy?

Answer 3

The heat comes from the earth’s core. The energy comes out to the surface through the plate boundaries and edges where most formation of volcanoes occurs

Question 4

300-700*F temperature

Answer 4

most reliable method before putting up a geothermal power plant

Question 5

50-60*F temperature

Answer 5

used for geothermal heat pump

Question 6

What are the three main types of geothermal energy systems?

Answer 6

1. direct use and district heating
2. geothermal power plants
3. geothermal heat pumps

Question 7

What are the three basic types of geothermal power plants?

Answer 7

1. dry steam plants
2. flash steam plants
3. binary cycle power plants

Question 8

it sips directly hot steam beneath the ground through pipes to mobilize generator turbines

Answer 8

dry steam plants

Question 9

it pipes high pressure hot water from geothermal reservoir and convert it into steam that turn generator turbines to produce electricity

Answer 9

flash steam plants

Question 10

it has a system that transfers heat from hot water sipped miles deep to other liquid. Exceedingly high temperature from geothermal water changes the other liquid into steam to drive the generator turbines

Answer 10

binary cycle plants

Question 11

How does heat pump work?

Answer 11

It transfers heat from the ground (or water) into buildings during winter and reverse the process in the summer with the use refrigerant

Question 12

How does a geothermal power plant work?

Answer 12

The steam comes from reservoirs of hot water found a few miles or more below the earth’s surface. The steam rotates a turbine that activates a generator, which produces electricity.

Question 13

The conversion of flowing water (mechanical energy) into electical energy

Answer 13

Hydropower or hydroelectricity

Question 14

What are three main types of hydro plants?

Answer 14

1. Impoundment facilities
2. Pumped storage facilities
3. Run-of-River

Question 15

uses dam to create a large reservoir of water

Answer 15

Impoundment facilities

Question 16

Similar to impoundment but have a second reservoir below the dam. Water can be pumped from the lower reservoir to the upper reservoir, storing energy for later.

Answer 16

Pumped storage facilities

Question 17

Relies on natural water flow rates, diverting just a portion of river water through turbines, sometimes without the use of dam or reservoirs.

Answer 17

Run-of-River

Question 18

What is more dangerous for the environment, Geothermal or Hydroelectric power plant?

Answer 18

Hydroelectric power plant, because in geothermal it can still be recycled. While Hydro requires construction for the dams. It can also cause flooding for the upper area and the habitats of animals.
