What is the role of a gearbox in wind turbines?
To adjust the speed of the turbine's rotation to match generator requirements.
What is the effect of increased tower height in wind turbines?
It places rotor blades in higher velocity winds, improving energy extraction.
What is a disadvantage of offshore wind farms?
They may encounter adverse environmental conditions like saltwater and severe storms.
What is the typical capacity factor for wind energy in the U.S.?
34% on average, with 40% considered very good.
What is the primary challenge of maintaining hydropower systems?
High capital costs and potential environmental impacts.
What is the role of fish ladders in hydropower?
To facilitate fish migration past dams.
What are the maintenance considerations for wind turbines?
They require low operating and maintenance costs but can be affected by environmental
conditions.

,What is the significance of the 'duck curve' in California's energy grid?
It illustrates the impact of increased renewable energy on electricity demand and supply.
What is the primary energy basis for hydropower production?
Gravity, which converts potential energy.
What does 'net hydraulic head' account for?
It considers pressure drops in piping and valves.
What is the length of the Three Gorges Dam?
3035 meters.
What is the height of the Three Gorges Dam?
185 meters.
What is the installed capacity of the Three Gorges Dam?
22,500 MW.
What type of turbines are used in the Three Gorges Dam?
32 hydraulic turbines, each rated at 700 MW.
What is the range of power generation for small-scale hydropower?
0.01 to 30 MWe.
What defines microhydro systems?
They produce less than 100 kWe.
What is a Kaplan turbine?
A reaction turbine using propeller blades for low-head applications.
What are the two main categories of hydraulic turbines?
Impulse turbines and reaction turbines.

, What is an example of an impulse turbine?
The Pelton wheel.
What is the purpose of pumped hydro storage?
To generate electricity during peak times and store energy from intermittent renewables.
What are the four primary categories of ocean-based power systems?
Ocean thermal, ocean wave, ocean tidal, and ocean current.
What is Ocean Thermal Energy Conversion (OTEC)?
A process that relies on temperature gradients between warm surface water and cold deep
seawater.
What is the typical thermal efficiency of OTEC?
2% to 3%.
What is a point absorber in wave energy technology?
A floating structure that moves relative to wave action to harness energy.
What is the function of an oscillating water column in wave energy converters?
It generates electricity by using the pressure changes caused by incoming and retreating waves.
What is a significant challenge for ocean power systems?
Saltwater corrosion and potential collisions with shipping traffic.
What is the estimated wave energy potential in the Pacific Northwest?
40 to 70 kWe per meter of coastline.
What is the role of guide vanes in a reaction turbine?
They redirect water inward toward the turbine blades.
What is the main advantage of ocean power?
