wer Background

WIND TURBINES – structures that harness the energy from the wind by converting its kinetic energy into mechanical and electrical energy.

Grouped into WIND FARMS, which are either onshore or offshore.

Largest on shore wind farm – Roscoe Wind Farm in Roscoe, Texas

wer A WIND TURBINE’S DESIGN:

•WINGS - like an airplane’s propeller

•WEATHER VANE at the shaft – connected to the computer which controls the velocity of blades

•GEARS LOCATED INSIDE THE SHAFT –Big gears help increase the velocityOf the blades

SWOT Analysis

Strengths

• Free, renewable resource• No harmful emissions• No need to purchase fuel • Minimal operating and

maintenance (O&M) expenses

• Minimal land use

SWOT Analysis

Weaknesses

• High cost of initial investment

• Wind supply may be unreliable and can only be used in support of existing electric grids

• Can only be located in uninhabited areas

• Can produce noise at uncomfortable levels

SWOT Analysis

Opportunities

• Philippines’ location in the monsoon belt results to several potential wind farm locations

• Expansion resulting from the inclusion of the RE sector in the Investment Priorities Plan (IPP)

• Growth from development of small-scale wind turbines

SWOT Analysis

Threats

• Government bureaucracy• Limited available

technology for economical energy storage

Applications

• Bangui Wind Farm is a wind farm in Bangui, Ilocos Norte, Philippines. The wind farm uses 20 units of 70-metre (230 ft) high VestasV82 1.65 MW wind turbines, arranged on a single row stretching along a nine-kilometer shoreline off Bangui Bay, facing the South China Sea.

Cost Benefit Analysis

The planning of a wind farm

It’s never just one windmill.

Steps:1. Set target power

requirement.2. Canvas Turbine Costs.3. Identify a geographical area4. Negotiate Construction Bid.5. Build.

Cost Benefit AnalysisSo how much does it cost exactly?

It depends.

Cost is typicallymeasured in MEGAWATT.

Cost Benefit AnalysisFor Example: Bangui Windmills

Therefore, the cost is roughly $2.27M per

megawatt.

Cost Benefit Analysis

Maintenance Cost

•Less than investment cost

•Estimated to be 2-3% of total investment cost annually

•Increases as Turbines Age

•Developing new turbines that last longer

Cost Benefit Analysis

For Example: Bangui Windmills (cont..)

• Operated by Transco Laoag• Estimated 21 year life• Sells power to INEC for Php4.43 / kWh

under Electricity Sales Agreement

• This price already includes both maintenance and investment cost

• Consider this price versus Meralco’s Rate of roughly Php6.67/kWh

Cost Benefit AnalysisWhat this costs could mean to you:

For example:

Use Macbook Pro 35 Hours a week.

30watts x 35hrs/wk x 52wks/yr

= 54,600 watts/hr or 54.6 kWh

Cost:(Meralco)

54.6 kWh x 6.67 = Php364.18(Wind)

54.6 kWh x 4.47 = Php244.06

Cost Benefit AnalysisCommon Household Items Power Use

Annual Consumption in the Philippines in 2011 was

54,400,000,000 kWh.

Cost Benefit Analysis

• Estimated savings of .07 centavos for every kilowatt-hour produced against fossil fuel power

• Will help an estimated number of 70, 000 household

• Reduced CO2 emission by 56,788 of CO2 per year

• Reduced risk of respiratory problem

Benefits

Ethical Implications Is Wind Power a Green Energy Source?

Impacts to the Ecosystem

• Could kill animals in flight (e.g. eagles, bats, migratory birds)

• Important concern in biodiversity hotspots

Ethical Implications Is Wind Power a Green Energy Source?

Impacts to Surrounding Communities

• Sickness from noise pollution– insomnia– headaches

• Devaluation of Lands– Less people could tolerate

noise from wind turbines

Ethical Implications Is Wind Power a Green Energy Source?

On Job Creation of the Industry

Wind turbines are manufactured in China

Maintenance of wind turbines not labor intensive

Nation-Building Implications

• Seeing that wind farms could only be put up in strategic places in the country, these provinces and other provinces surrounding it would have more opportunities.

• This will provide the local community will more jobs and a means of livelihood.

• Opening such wind farms to these provinces will provide both white collar and blue collar work opportunities.

The benefit in investing on wind energy for the environment is quite obvious.

Having this kind of renewable energy would definitely be advantageous for the environment. But when a country, the Philippines in this case, shifts to this new kind of renewable technology, how would it affect growth of the country?
