So, the electricity for the cars uses how much coal burned?

What the green power fanatics don’t want you to know!

Then, what they wont tell you, is how much coal is burnt to produce the concrete for a wind turbine:

The figure of 120 cubic metres  or around 290 tonnes of concrete per installed MW appears to be about right.

Therefore a 6 MW plated capacity turbine will have around 720 cubic metres / 1700 tonnes of concrete in its base.

It takes around 300 to 400 kg’s of Cement to make one cubic metre of concrete .

From that and using the higher strength, more cement per cubic metre concrete , say 400 Kgs of Cement per cubic metre of concrete, a typical 6 MW turbine base will use about 290 tonnes of cement to make the base.

Now to make the Cement clinker which is then ground to a fine powder in ball mills to produce the fine powder we call Cement,
As the quote below, it takes about 200 kg of coal to produce one tonne of cement and about 300-400 kg of cement is needed to produce one cubic metre of concrete.

Cement is made from a mixture of calcium carbonate (generally in the form of limestone), silica, iron oxide and alumina. A high-temperature kiln, often fuelled by coal, heats the raw materials to a partial melt at 1450°C, transforming them chemically and physically into a substance known as clinker. This grey pebble-like material comprises special compounds that give cement its binding properties. Clinker is mixed with gypsum and ground to a fine powder to make cement.Coal is used as an energy source in cement production. Large amounts of energy are required to produce cement.
It takes about 200 kg of coal to produce one tonne of cement and about 300-400 kg of cement is needed to produce one cubic metre of concrete

From this we can calculate that the tonnages of coal used to produce the cement used in a typical late model 6 MW wind turbine base is about 60 tonnes of coal or as a rule of thumb for coal use required to produce the Cement for the concrete in the base of wind turbine, a rough rule of thumb would seem to be that it takes roughly ten [ 10 ] tonnes of coal per installed and plated MW capacity of the turbine to produce the Cement for the base of the onshore turbines.

Now to be very clear on this, I am ONLY counting the amount of coal used to produce the cement for the concrete in the base of a turbine.
The energy costs of mining, processing, transporting, mixing the concrete, digging the hole, steel reinforcing energy costs, road building to the site, machinery to install all the systems and turbine energy use, cabling and its installation underground, production of transformers and etc plus Grid line extensions to the turbine farm, use of Grid energy used by the turbine in non generating standby mode about 8% to 12% of turbine capacity and etc and etc have NOT BEEN INCLUDED in this rough calculation of the energy used and the coal used to build the site systems for a turbine.

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.
