In the US, about 50% of total electricity, but it varies from one country to another.
Coal power plants typically produce around 2-3 kilowatt-hours (kWh) of electricity for every pound of coal burned. The energy produced can vary depending on the efficiency of the plant.

There are more coal plants than solar plants because the cost per Mega-Watt is much less using coal than solar power, and currently coal is more efficient. The problem today is that in a environmentally conscious society coal is a 'dirty' fuel, and solar power is clean. That is why environmentalists are pushing for more Solar (and wind) power generation.
There is around 2,000 pounds of carbon dioxide waste produced by coal power plants. This is released by a natural gas.
They are more thermodynamically efficient because they produce higher quality steam. However they also produce a lot of carbon dioxide and other things like sulfur dioxide, that are undesirable, which nuclear plants don't produce. I don't think using the word 'better' can mean much, both have their advantages and disadvantages.
Much cleaner than coal powered plants (no emissions) - although there is nuclear waste Produce relatively cheap energyProduces extremely large amount of energy compared to a coal plant
Yes, coal is very much still in use. Many power plants burn cola to produce electricity, particularly in under developed countries with growing economies. China is one of the largest users right now.
In the US, 49 percent of total production of electricity
Power plants fired by coal produce many pollutants (SOx, NOx, radiation, particulate, mercury etc.) the amounts vary by the size and fuel used at the site (not all coal produced the same contaminants). See the Links for data on typical coal plants.
1 kg of U-235 will produce as much energy as 1500 tons of coal
In terms of the environment, nuclear power is much better. Fission plants emit no greenhouse gasses or carbon, and -all- of the waste can be completely contained onsite. Living next to a coal plant would actually expose you to much much more radiation than living next to a nuclear plant, because the airborne effluents produced by burning coal is highly radioactive. It's one of those things people need to get educated about. The coal industry spends millions to spook everyone about fission, and it makes me cringe to see highly advanced fission systems like in Germany and Japan be swept away by fear and the extraction industry propaganda.
