a dangerous strategy … wind power

A new paper out shows how wind power does does serious damage to the electricity grid, and can never be used for base load power:


Engineers are required to do more than merely analyse and report on natural

phenomena. They are required to create practical solutions to real world problems. In

so doing they must test and design systems ensuring that they have addressed the worst

case scenarios. As a result, they may not concentrate merely on average values. With

these requirements firmly in mind, to the electrical engineer, a careful scrutiny of the

available wind farm operational data shows that, on the eastern Australian grid, it is

not possible for wind energy ever to displace dispatchable, reliable generation

supplying the base load demand. In this regard, an examination of the graphs

comprising Figure 3 clearly indicates that the proposal by some Australian

policymakers to replace major coal-fired power stations with a fleet of wind farms is

not technically achievable.

Additionally, the analysis shows that further increased wind penetration, even if

spread evenly across the eastern Australian grid, will result in an increasing

contribution to grid instability, potentially making wind energy an increasing threat to grid operational security and reliability. To continue a policy strategy to increase wind penetration across the eastern Australian grid, to seek to meet a target of some 20%

installed capacity, as has already been achieved in South Australia, (with the

presumption that wind may thereby meet 20% of base load requirements), has the

potential to be a dangerous strategy.

Read the full paper. Warwick Hughes has more on ABC’s wet dream, ‘coal is bad’ meme:

GreenLeft Australian ABC repeats anti-coal story five times on news front page

It must cruelly piss them off that global wind plus solar electricity generation in 2014 tallied only 3.8%

This is the yarn repeated five times – Are we witnessing a turning point in the future of coal?
Here is a chart of global electricity generation –

data from BP Statistical Review.
And amazingly 8.6% voted Green at the 2013 Federal Election.

About Tom Harley

Amateur ecologist and horticulturalist and CEO of Kimberley Environmental Horticulture Inc. (Tom Harley) Kimberley Environmental Horticulture Incorporated Kimberley Environmental Horticulture (KEH) is a small group of committed individuals who promote the use of indigenous plants for the landscaping of parks and gardens. Rehabilitation of Kimberley coast, bushland and pastoral regions are also high on our agenda. This includes planting seedlings, weed control, damage from erosion or any other environmental matter that comes to our attention. We come from all walks of life, from Professionals and Trades oriented occupations, Pensioners and Students, Public Servants and the Unemployed. We have a community plant nursery where we trial many old and new species, with a view to incorporating these into our landscaping trials. Our labour force are mainly volunteers, but with considerable help from the 'work for the dole' program, Indigenous Community Development Employment Program (CDEP) groups and the Ministry of Justice, with their community work orders; in this way we manage to train many people in the horticultural skills needed for indigenous plant growing. We constantly undertake field trips that cover seed and plant collection in the Kimberley. Networking around the Kimberley region and the east Pilbara is a necessary part of promoting our activities. We consult on a range of Environmental and Landscaping matters that deal with our region. Our activities involve improving Broome's residential streetscapes by including 'waterwise' priciples in planting out nature strips. Sustainable environmental horticulture is practised by members of our group. We use existing vegetation as the backbone of any plantings, using these species to advantage when planning to develop tree forms or orchards. The Broome region is sensitive to development. Subsequently many weed species have become dominant in and around developed areas. The use and movement of heavy machinery is the biggest single cause of environmental degradation. We dont live in a 'Tropical Paradise' but on the edge of the Great Sandy Desert. The plants that survive best here, grow in well-drained pindan sand, and are found from the Dampier Peninsular southward to where average rainfall is below 600mm. When we use rainforest species, detail is important when planting, water catchment, sunlight and understorey species are all considered. The use of recycled 'grey' water is an advantage here as well as treated waste-water, although many local species do not fare well with nutrients from this source. We use waterwise planting methods which include harvesting asmuch rainwater as possible, with swales designed to hold up to 200 litres, to help recharge the local groundwater aquifer. There has been a serious decline in this aquifer over the last few years. With the fast expansion of the Broome peninsular, more and more land is being covered by concrete, iron and bitumen so that much less water is available to replenish the aquifer, allowing the salt content to become significantly higher. The small Broome Peninsular is on the south-western corner of the Dampier Peninsular (bound by Broome, Derby and Cape Leveque at the northern tip). Compaction by vehicles also inhibits water retention due to the content of our local pindan sand, hard as concrete in the dry, going to soft and sloppy mud after rain. None of us are botanists, inevitably we have got some names wrong, names changed, or have not gone to sub-species level.

    “Are we withessing a turning point in the future of coal?”

    I’m beginning to think we are.

    It is called “up”
