Based on known oil reserves and the worldwide consumption rate, most estimates suggest this reserve has only 50 more years of production left in it.

89% of US total energy comes from fossil fuelsFossil fuel combustion represents a global

environmental problem U.S. winds could generate more electricity in 15

years than all of Saudi Arabia's oil, without being depleted

The choice is: Invest in discovery of new oil reserves (e.g. off-shore,

shale oil) Invest in clean coal technology (20% of the worlds supply

of coal is in the US) Invest in alternative energies

Aeromotor markets their windmills to pump water to irrigate crops and feed cattle. This new system opens up the South Plains of Texas and makes living in West Texas possible. Oil, cattle, cotton industries shape the new economy of Texas.

In 2006, Texas

overtook

California and

continues to lead

the nation in total

installed wind

capacity, shaping

our state’s future

economy and

strengthening our

importance in the

global

marketplace.

Texas is still #1

With advanced

engineering and

aerodynamic

designs, today’s

wind turbines

are more

powerful than

their

predecessors.

Presently

What are wind energy applications?

Power usage

•Irrigation pumps

•Entire residence•Street lights

•Electric fences

•Barn dances

•Etc..

•Appliances

Small wind systems•1+ megawatts

•1 mW = 1,000,000 watts•Weigh over 100 tons•Each blade is over 100’•200’ tower•Also $1,000,000 turbines•Not more efficient, just bigger

• Up to 100kW•1 kW = 1,000 watts

•Weigh 5oo lbs to 5 tons•Blades are 6’ to 30’ each•Towers up to 100’•Home, ranch, farm, business•Eligible for grants and rebates

Off-Grid

•Make sure you are

allowed to install a

wind turbine

•Make sure you have

sufficient wind speed

•Find out what your

electrical usage is

•Find funding/grant

sources for your area

Check list:

Zoning Approval

•NIMBY

•HOA

•City

•County

•Minimum

•Height

restrictions

•110% rule

Finding the wind speed?

Resources

•Local airport

•Local media

•Internet

•Trees and flags

•Anemometer

•Electric usage is

listed in kWh.

•This data is on

every monthly

statement.

Monthly Electricy Usage

Convert turbine’s output power (W) into kW (W) x (.001) = kW

Convert kW into kWhHow many hours in a year?

(365.25) x (24) = 8,766 hrs/yearHow many hours in a month?

8,766 / 12 = 730.5 hrs/month(730.5) x (kW) = kWh/month

Wind speed?Monthly electrical

usage?Typical sizes needed

2kW – ½ of your energy 5kW – almost all energy 10kW – all, plus surplus 20kW – small biz, ranch 30kW – med. biz, ranch <100kW – large ranch,

village
