in 2014 how much of the world electricity was generated from coal?
151847
In 2014, the share of world energy consumption for electricity generation by source was coal at 41%, natural gas at 22%, nuclear at 11%, hydro at 16%, other sources (solar, wind, geothermal, biomass, etc.) at 6% and oil at 4%. Coal and natural gas were the most used energy fuels for generating electricity.

There are currently four active coal-fired power stations operating in the United Kingdom which have a total generating capacity of 5.8GW.

Hydroelectric power has been generated for over 140 years in Britain and was first harnessed in 1878 to power the lights of Cragside country house in Northumberland, England. As of 2017, hydropower accounts for around 1.8% of Britain's total electricity supply and 18% of our renewable energy.

As a rule of thumb you would need about 138 Kg of coal (26GJ/Ton) to produce 1 ton of steam. About 800 – 1,100 lbs (364 – 500 kg) of coal to generate 1 MWh of electricity.

1882. The world's first steam driven power station was built on coal at Holborn Viaduct in London.

Coal-fired plants produce electricity by burning coal in a boiler to produce steam. The steam produced, under tremendous pressure, flows into a turbine, which spins a generator to create electricity. The steam is then cooled, condensed back into water and returned to the boiler to start the process over.

A standard 500 megawatt coal power plant produces 3.5 billion kWh per year, which is enough energy to power 4 million light bulbs all year. To power most of a household's electrical appliances for a year it would take around 4,750 pounds of coal.

Australia is heavily dependent on coal for electricity, more so than any other developed country. About 60% of electricity production is derived from coal.
1012690
The Canadian energy industry generated 652.3 terawatt-hours (TWh) of electricity in 2017. Total electricity generation in Canada in 2017 was 652 terawatt hours. Hydro has the highest share of generation at 60%, followed by nuclear at 15%, coal at 9%, gas/oil/others at 10% and non-hydro renewables at 7%.
1112822
In 2019, there were geothermal power plants in seven states, which produced about 16 billion kilowatthours (kWh), equal to 0.4% of total U.S. utility-scale electricity generation. In 2017, about 26 countries, including the United States, generated a total of about 80 billion kWh of electricity from geothermal energy.

Fossil fuel power plants burn coal or oil to create heat which is in turn used to generate steam to drive turbines which generate electricity. ... In 2017, fossil fuels generated 64.5% of electricity worldwide. These plants generate electricity reliably over long periods of time, and are generally cheap to build.

How much of U.S. energy consumption and electricity generation comes from renewable energy sources? In 2019, renewable energy sources accounted for about 11% of total U.S. energy consumption and about 17% of electricity generation.
5844
In 2018, total U.S. electricity generation by the electric power industry of 4.17 trillion kilowatthours (kWh) from all energy sources resulted in the emission of 1.87 billion metric tons—2.06 billion short tons—of carbon dioxide (CO2). This equaled about 0.99 pounds of CO2 emissions per kWh.

The world's two largest coal consuming countries in 2019 were also the world's two most populous nations: China and India, at 81.7 exajoules and 18.6 exajoules consumed. These figures equate to approximately 51.7 percent of the world's coal consumption in China, while India accounted for 11.8 percent.
