RENEWABLE RESOURCES
Renewable resources are natural resources that can be replenished in a short period of time.
● Solar ● Geothermal
● Wind ● Biomass
● Water
Factors of consideration
Site selection
Altitude, wind strength, constancy, grid access, …
Turbine selection
Design (HAWTs vs VAWTs), vendor, size, quantity,
Turbine Height: “7th root law”
Local topography (hills, ridges, …)
Turbulence caused by other turbines
Prevailing wind strengths, direction, variance
Ground stability (support massive turbines)
Grid upgrades: extensions, surge capacity, …
Non-power constraints/preferences
Environmental (birds, aesthetics, power lines, …)
Cause radar clutter (e.g. near airports, air bases)
