Wind farms anger native Mexicians

Not everyone likes green technology.

This is especially true when the people's view and welfare are not thoroughly examined and considered. I am not implying that what happened in Mexico is a case of local inhabitants being sidelined, but from the following piece of news by AP, the locals seem like being let down by big companies investing in wind energy.

This reminds me of the big conglomerates opening up vast area of land in Sabah to plant palm oil at the expense of the small holders (local population).

If you read this article, you will find that big portion of the frustration is due to lack of participation of the local community.

Nonetheless, a remarkable work by Mexico government in promoting renewable energy. The following is the cumulative amount of energy derived from wind:

2006 - Mexico has only 6 MW of wind power
2011 - 519 MW
2012 - 1.3 GW

By comparison, global installed capacity is estimated at 244 GW, with China as one of the biggest investors.


Indigenous vs. multinationals in Mexico wind power

Mexico is putting up wind power turbines at a breakneck pace and the expansion is pitting energy companies against the Indians who live in one of the windiest spots in the world.

The country is posting one of the world's highest growth rates in wind energy, and almost all of it is concentrated in the narrow waist of Mexico known as the Isthmus of Tehuantepec, where winds from the Pacific meet winds from the Gulf of Mexico, spawning places so wind-blown that one town's formal name is simply "Windy."

The largely indigenous residents of the Isthmus complain that the wind farms take control of their land, affect fish and livestock with their vibrations, chop up birds and pit residents against each other for the damage or royalty payments. They also claim they see few of the profits from such projects.

President Felipe Calderon has made the inauguration of wind parks one of the main focuses of his administration's ambitious pledge to cut Mexico's carbon emissions by 30 percent by 2020, and on Tuesday — as he has done before — he stopped by the state of Oaxaca to inaugurate a new clutch of wind turbines, praising the extra income they provide for some farmers.

"Yes, you can fight poverty and protect the environment at the same time. This is a clear example," Calderon said at the opening ceremony.

But as in the past, he did so under tight security, as local protesters threatened to mar the inauguration. The president's office normally publishes a detailed schedule of his planned activities, but didn't do so with Tuesday's inauguration, keeping it under wraps until the event took place.

So far in 2012, Mexico has posted a startling 119 percent increase in installed wind-power capacity, more than doubling the 519 megawatts it had last year, the highest annual growth rate listed in the magazine Wind Power Monthly's "Windicator" index. Mexico had only 6 megawatts when Calderon took office in 2006.

While Mexico, with a total of around 1.3 gigawatts of wind power, is still a tiny part of the world's estimated 244 gigawatt capacity, it offers an insight into what happens when the industry focuses overwhelmingly on large farms dominated by large companies that are concentrated in a small, desirable area.

It has been mainly Spanish firms like Iberdrola, Union Fenosa and Gamesa, and U.S. firms like Sempra Energy, that have built the huge wind towers that now crowd the Isthmus of Tehuantepec, leaving the local population feeling invaded. Only 4 of Mexico's 17 wind farms are located outside the isthmus.

It raises the question of whether bigger is always better.

"We are asking these multinationals to please get out of these places," said Irma Ordonez, an activist from the Zapotec Indian town of Ixtepec, Oaxaca. "They want to steal our land, and not pay us what they should."

"When they come in they promise and promise things, that they're going to give us jobs, to our farmers and our towns, but they don't give us anything," said Ordonez, who traveled to Mexico City in October to protest outside the offices of a Mitsubishi Corp.

Industry sources say the distrust is unmerited, given the potential benefits to the poverty-stricken farming and fishing towns on the isthmus.

The latest battle focuses on a huge, 396-megawatt off-shore wind farm planned for a narrow spit of land in a lagoon near the village of San Dionisio del Mar, Oaxaca.

A source close to the project, who was not authorized to speak on the record, said the project had been approved by village assemblies, would have little impact on fishing activities in the lagoon and would contribute an amount equal to about half the township's annual budget in coming years in compensation and royalties.

£365mil onshore windfarm - The biggest yet in England and Wales

The Guardian reported that the government has approved plans for the giant onshore wind farm in England and Wales which could power 206,000 homes a year. While this is a completely green energy source, it has come under criticism from countryside lovers, who said that the farm would be ugly and that it will ruin the beautiful landscape of the proposed site.

With wind turbine standing at 475ft tall, I can't help but saying "Wow! This is one monster mill!"

By comparison, London Eye is 443ft tall (135m). Closer to home, the Singapore Flyer's (big wheel) height is 541ft (165m).


Image: The Telegraph. These wind turbines (Beinn An Tuirc wind farm) in Scotland has been criticised by many as unsightly.



The farm details in brief

Cost                            : About £365mil (RM1.82bil)
Location                     : Pen Y Cymoedd development, south Wales
Area                           : 155 acres across countryside
Number of turbines    : 76, each with 3.3MW max output
Turbine height            : 475ft (145 metres)
Generating capacity   : 299 MW by 2016
No. of homes served  : 206,000
Developer                  : Vattenfall

Vatenfall, the developer behind the project, also operates the largest offshore wind farm in England and Wales, which produces 300 MW of energy with 100 turbines.

Another big offshore project near Margate, Kent, is already in the works by London Array and this farm would produce 1,000 MW from the 341 turbines. We know that the UK is a country suitable for harnessing energy from the wind. Last month, The Independent carried an article on British engineer Offshore Group Newcastle's optimism of creating up to 1,000 jobs from wind farm.


TheGreenMechanics' two cents:

It seems that erecting the bigger turbines are better done offshore, where the mixture of environment and the turbines can be better tolerated.

Unsightly as some say it is, wind farming is more sustainable compared to the generating energy using fossil fuel. It is an idea, and people can continue to debate it but in the end one still need to decide what's acceptable to the bigger population in a long run.

Wind turbines as RE source

Apart from solar PV, wind mills and hydro-electric are the other two Renewable Energy sources that interest me. They offer different kind of challenges but could also be very rewarding.

I mentioned in my previous article about Sabah's good potential in harnessing energy from wind by putting up wind turbines offshore on its northern tip. Recently, a local company thought that Sabah could be the beneficiary of its RE initiative in testing the viability of vertical wind turbine power generator.


Daily Express - April 25, 2012


Apart from Pulau Perhentian in Terengganu, Sabah has the right geographic factors to generate enough wind for wind-turbine projects that can be worked out between corporate bodies or private investors and SESB.

Pernec Corporation Berhad, one of the exhibitors at the popular MSAM 2012 currently on-going at Kota Kinabalu Sports Complex in Likas, told the media that it is planning a further discussion with SESB on a possibility of using vertical axis wind turbines as an alternative renewable energy source. One of the RE industry solutions offered by Pernec is wind turbine. Pernec claims that its wind turbine emits low noise and can generate between 300W and 25kW; most suited for windy and coastal areas or islands.

The company also provides environment-friendly solutions for our everyday needs such as power (solar PV), lightings (LED), refrigeration & air-conditioning (green HC refrigerant), as well energy saving and conservation through efficient energy management system.


Wind turbines

Coming back to wind turbines, in Hawaii, there have been complaints from residents staying nearby wind farm. It was reported that the noise from the wind turbine blades is very loud and sometimes intolerable. Hawaii government is currently actively  perusing RE initiatives, particularly wind farming, to reduce it dependence on fossil fuel.

Pernec claims that the company's turbines emit  low noise, so, it is very interesting to find out how they make this possible. But looking at the highest capacity of 25kW, noise level may not yet be an issue. Vertical construction may also play a part in keeping noise level in check.

The company is believed to be planning a pilot project on vertical axis wind turbine in Sabah and if this materialises, SESB should take it seriously. Not just because it helps in preserving the nature but also the possible long term profitability of such venture. 

Let's harness energy from 'thin air'.

British OGN to create 1000 wind farm jobs

This is very interesting. The British government is giving out grant for a company willing to venture into something new, creative and at the same time create job opportunities.

Already for sometime now, we know of at least two areas in Malaysia where wind is blowing at speed viable for tapping of electricity 'from thin air'. These are Kudat/Banggi in the northern tip of Sabah and Pulau Perhentian in Terengganu. Pulau Perhentian (Besar & Kecil) are two resort islands but building some industrial scale wind turbines, if carefully crafted, should not ruin the beautiful scenery and serenity of these places.

The rest of the news @The Independent
The Independent, April 13, 2012

LONDON: British engineer Offshore Group Newcastle (OGN) announced on Friday that it would create up to 1,000 jobs after receiving a government grant to help build offshore wind farms.

OGN said in a statement that it had been handed a grant worth $1.02 million (£640,000) to help stimulate employment prospects in Tyneside, northeast England, where the group is based.

The firm said it will build a prototype steel-jacketed foundation at its site in Wallsend, Tyne and Wear, starting later this year. The foundation structures will be designed for large wind turbine generators in waters over 30 metres (100ft) deep.

"OGN has received a vote of confidence from the Department of Energy and Climate Change for its move into offshore wind technology," it said in the statement.

"And the northeast economy shares in the benefit with the creation of up to 1,000 long term jobs."


Malaysian perspective

If wind farm is too costly to erect in the mountainous terrains of Malaysia, we should consider building them offshore. Never shut down an idea until a detailed study is carried out. Allocate some grant and ask someone willing to do the study to be given the money.

Japan is doing it now in the waters near Fukushima following of the recent catastrophic tsunami and nuclear reactors failures. Also, in the northern island of Hokkaido, a large scale solar PV farm is already in the pipeline.
