Wind energy

History

Wind energy has been harnessed since the 19th century in the form of windmills for mechanical energy. The 20th century brought the wind turbine which is used to create electricity.

Wind is actually a product of solar energy. The sun’s rays heat the Earth’s surface creating temperature differences between the land, water, and air, given their different propensities to absorb heat. This phenomena, in conjunction with the temperature differences that exist between the equator and the Earth’s poles, creates wind as hot air rises, expands, becomes less dense, and is then replaced by denser, cooler air (nesea).

Historically wind energy produces electricity at an average of about $.04 per KWh.


Wind energy

Problem

  • UTPB consumes 1.1 megawatts per month

  • That equates into aprox. $110,880.00 per month.


Wind energy

AV

AeroVironment has operated since 1977 with over 250 sponsored projects to date. Primarily operate in California and principal researcher on the California Energy Commission

Boston’s Logan airport currently has 20 turbines on their office center combining for an annual savings of $13,000.

Maui Ocean Center has 6 turbines for 48,880 KWH per year.


Wind energy

Solution 1

  • Supplement electrical consumption with small turbines on top of mesa building.

  • Operates at winds speeds of 4mph to 120mph

  • Low operating expenses

  • Low noise level

  • Small size

  • Low maintenance cost


Wind energy

Solution 1 cont.

  • Each turbine produces 1 Kw/hr.

  • Building provides 50% more power generation.

  • Uses high voltage DC buss which makes the system “plug and play” resulting in lower installation costs.

  • Each turbine cost $10,000 for complete installation and setup.


Wind energy

Solution 2

  • No. 1 in Modern Energy

  • With a 23% market share, and 35,500 wind turbines installed, Vestas is the world's leading supplier of wind power solutions.


Wind energy

Solution 2 cont.

  • University Lands owns 2.2 million acres in Texas, with the majority being in West Texas.

  • UTPB owns 200 acres at C.E.E.D.

  • High power generation

  • Expensive shipping and installation cost

  • Large “footprint”


Wind energy

Recommendation

Cost Analysis

AV

Each turbine produces 1kw/hr.

Each turbine completely installed : $10,000

Savings per yr per turbine: (1/3 time) $400

(2/3 time) $800

(full time) $1200

Total cost: $132,000,000 (13,200 turbines)

Break even : 8 - 25 yrs

Vestas

Each turbine is 2000kw/hr.

Hardware cost: $2,680,000

Installation /shipping: $680,000

Additional land: $120,000

Other charges: $400,000

Total cost: $3,880,000

Savings per yr: (1/3 time) $806,400

(2/3 time) $1,612,800

(full time) $2,419,200

Break even: 1.6-4.8yrs.

Based on $0.14 kw/hr.
