What is the impact of space radiation on solar cells in orbiting solar stations? -
ANSWER-It degrades the solar cells, reducing their efficiency.
What is the relationship between wind speed and solar energy? - ANSWER-
Wind speed generally increases with daylight heating and decreases after dusk.
What is the primary source of wind energy? - ANSWER-Uneven heating of the
Earth's surface caused by solar energy.
What is the role of a gearbox in wind turbines? - ANSWER-To adjust the speed
of the turbine's rotation to match generator requirements.
What is the effect of increased tower height in wind turbines? - ANSWER-It
places rotor blades in higher velocity winds, improving energy extraction.
What is a disadvantage of offshore wind farms? - ANSWER-They may
encounter adverse environmental conditions like saltwater and severe storms.
What is the typical capacity factor for wind energy in the U.S.? - ANSWER-
34% on average, with 40% considered very good.
,What is the primary challenge of maintaining hydropower systems? -
ANSWER-High capital costs and potential environmental impacts.
What is the significance of the Sihwa Lake Tidal Power Station? - ANSWER-It
has a capacity of 254 MWe, eclipsing La Rance
What is the mean operating tidal range of the Sihwa Lake Tidal Power Station?
- ANSWER-18 feet
What is the formula for calculating power in ocean current power systems? -
ANSWER-Ptot = ρ A v³ / 2 gc
What is a tidal stream turbine? - ANSWER-A turbine similar to a wind turbine,
but underwater
What are some challenges of ocean current installations? - ANSWER-Clearance
for shipping, fishing accessibility, fish injury, maintenance issues
What is the purpose of energy storage in renewable energy systems? -
ANSWER-To manage the unavailability of intermittent energy sources
What are dispatchable energy sources? - ANSWER-Fossil, nuclear, biomass,
and geothermal
What is demand side management (DSM)? - ANSWER-Adjusting electric rates
and utility control to manage energy demand
What is the role of energy storage in economics? - ANSWER-To reduce peak
loads and capital expenditures for peak plants
, What is the density of seawater compared to air? - ANSWER-850 times greater
What is a significant issue with tidal energy output? - ANSWER-Hydraulic
turbines cannot be 100% efficient
What is the expected output power of La Rance if the efficiency is 40%? -
ANSWER-327 MW
What is the purpose of ASU Thermal Energy Storage? - ANSWER-To reduce
peak electric demand by 6800 kW and incur off-peak rates.
How much water can the ASU Thermal Energy Storage tanks hold? -
ANSWER-5.5 million gallons.
What is the capital cost of the ASU Thermal Energy Storage system installed in
1990? - ANSWER-$5 million.
What annual savings does the ASU Thermal Energy Storage system provide? -
ANSWER-$500,000.
What is pumped hydro energy storage? - ANSWER-A method of storing energy
by using water pumped to a higher elevation.
What is the role of batteries in energy storage? - ANSWER-To temporarily
store electric energy in a chemical energy form.
What are supercapacitors used for? - ANSWER-To store energy in an electric
field within high capacitance material.
What does SMES stand for? - ANSWER-Superconducting Magnetic Energy
Storage.
