I was trying to estimate the mining footprints of solar and nuclear, and came up with some very tentative rough estimates that ore input for solar energy might have an energy density (per unit mass) ~ 5 to 80 times coal, while nuclear (convential US fuel cycle) may be ~ 20 times coal — on the solar side, this doesn't include some balance of system components, and on the nuclear side, it only includes the U, but on the solar side, the actual energy density could get much higher with recycling of the same material into multiple successive generations of solar energy devices, and on the nuclear side, breeder reactors.
The way to decrease emission from oil is to increase miles - per - gallon standards for light vehicles and eventually to electrify light vehicle transportation while at the same time shifting away from coal to produce electricity to sources with much lower emissions (gas, wind, nuclear).
Natural gas is much more environmentally friendly than coal, which continues to be the mainstay of electricity production around the world and in the U.K. Gas emits less than half the CO2 per kilowatt hour produced, and it emits much lower amounts of other pollutants like nitrous oxide, sulfur dioxide, black carbon, carbon monoxide, mercury, and particulates.
Next, the wind investor is required to pay the government exactly as much per kWh generated as the coal plant would pay for coal.
How much cooling water does a nuclear power plant need compared with coal, geothermal and solar thermal plants (per MWh)?
The good news in the case of the UK is that it could have been a lot worse: Aberthaw, like all UK coal power plants, doesn't run that much because it has to pay a CO2 price of $ 30 per tonne.
There could be as much as 2,600 trillion cubic feet (tcf) of natural gas available domestically.63 The U.S. currently uses approximately 22 tcf per year.64 If the shale deposits meet their potential, these finds will certainly help accelerate the retirement of coal power plants and reduce our dependence on foreign oil and our foreign exchange imbalance.
Per memory (and you are much closer) most British coal mines were operating at a loss in 1984, so what they were producing was not economic reserves.
In terms of carbon emissions, new technology coal is still around 30 per cent higher than LNG but much lower than conventional coal powered generation.
China is certainly anxious to clean up its power generation because of the pollution, but it is now clear that the 3 per cent coal tariff was aimed not so much at reducing emissions but to try and make Australia agree to free trade agreement concessions — which it should not do.
Because the amount of cooling necessary is much less per unit of electricity output in NGCC plants than in coal or nuclear plants, dry cooling systems are more economical for NGCC plants than for other thermoelectric options.
That is because, as noted above, oil delivers much more value to society than coal does per tonne of CO2.
But the 2 tons of CO2 per ton of coal will likely cost as much to handle EACH as the coal, tripling cost.

If we ramp up new industries without reducing other things, we could see a short term increase in fossil fuel consumption and consequent CO2 emissions (relative to BAU), but if that is the start of a larger and permanent reduction of CO2eq emissions, then it's worth it (or in other words, much better to get 100 kWh per kg coal than 3 (or whatever much smaller number it actually is) kWh per kg coal).
The GED per kWh for natural gas is 20 to 30 times lower than for oil and coal, respectively, because its (non-carbon) emissions are so much lower (Table 5).
