Wind Power - An Age-Old Energy Source
Do we have an energy problem?
Community Wind SolutionsSmall Wind
• (100kW machines and under)
• Require 9 mph average wind speed
• Home owners
10 kW
1,500 kW
Community Wind Solutions
Community wind– Northern Power’s 100kW turbine– Rebuilt Utility turbines up to 250kW– Net metered, under 200 feet tall
Community Wind Solutions Wind Farms
– Provide wholesale bulk power
– Require 13-mph average wind sites at the minimum

= 120 X the energy at 20 X the cost
Technology Advances and Scale Economies Drive Down Cost
Wind Power CostsProject Size
Assuming the same wind speed, a larger wind farm is
more economical

Wind Power CostsWind Speed
Assuming the same size project, the better the wind resource, the lower the cost
Wind cannot compete with nothing . . .But nothing is not a real choice
Energy policy is all about choices and their consequences
Have an Energy Policy
Energy Planning Are we currently planning for the best use of
our wind resource? What is the current plan for the use of our energy
resources?
Energy-shed PlanningTown and regional plans should include
mapping and inventories of their natural energy resources – their ‘energy sheds” – which would include the wind resource.
By not planning for the use of natural energy resources, like the wind, we are accepting the status quo and abdicating our energy choices to others.
