Wind Power

What choices? Fossil fuels Geothermal energy Hydropower Wave power Solar power Wind power Nuclear energy

What choices? Renewable? Or non-renewable? Energy density –Energy release per mass of fuel used –Higher the energy density is, more likely to be economical Affordable?

What is wind power? Electrical power generated by wind spinning turbines Usually in the form of windmills Many variations to its form factor to increase efficiency

What is wind power?

E is energy, P is the power, A is the area through which the wind goes through, v is the wind speed, t is the duration, ρ is the density of the air.

Positives Renewable No limits to locations Consistent generation of power as long as sufficient wind is present

Negatives Low efficiency High building cost Maintenance is difficult Direction of the turbines have to be constantl y be monitored Does not work under abrupt change in wind d irection Takes up much space Produces noise ‘Unaesthetic’

Negatives North Ayrshire, Scotland Needs to be shut down in such emergency Too much wind destroys the turbine

How about in Jeju? High winds all year round Very adequate for wind power generation Already being implemented

How about in Jeju? Daejeong Offshore Wind Farm Hanlim Offshore Wind Farm Gashi-ri Wind Farm Haengwon Wind Farm Kimnyeong Shinchang From Jeju Energy Corporation

How about in Jeju? Haengwon Wind Farm 12 turbines 10,550KW

How about in Jeju? Demonstrational offshore wind farms in Hanlim and Daejeong Expected to produce 150 and 200MW each

Future? Still under research for harnessing more power Considered as one of the ‘greenest’ power source including solar energy and hydropower More governments are starting to invest
