The Sun's power output is about 3.8x1026 watts. I couldn't find actual figures for coal, so we'll base the calculations on graphite instead; graphite is essentially a very pure form of coal, so it shouldn't throw things off too far. Burning 12 grams of graphite gives off about 94 kcal. Let's call that 37 kJ/g, or 37 MJ/kg. A watt is a joule per second. So, we need to burn a bit over 1019 kilograms per second. Which is a lot. The density of graphite is, well, it varies but let's call it 2.5 tons per cubic meter, so it would be a cube about 160 km ... 100 miles ... on a side. Per second.
"Create as much energy" is poorly defined. The amount of energy produced from solar energy will depend on the surface area used for solar panels, the weather, the efficiency of the panels, and for how long it is used. Similarly, the amount of energy produced by a coal power plant would depend on its size, its efficiency (which of course may also vary), and for how long it is used. Please think about what exactly you want to compare.
Solar Power is primarily harvested by placing solar cells mostly made up of elements such as silver which take in the sunlight and later convert it into electrical energy. Though the energy produced in less in amount when compared to other energy sources such as coal and petroleum, it is a much cleaner fuel than both of them and is a non-renewable source of energy. Nowadays, it has become more popular due to it's non-pollution feature.
Sunlight provides approximately 173,000 terawatts of energy to the Earth continuously, which translates to about 1.74 x 10^17 watts. Over the course of a year, this amounts to roughly 600 quintillion joules of energy, far exceeding the total energy consumption of humanity. This immense energy supply underscores the potential for solar power as a sustainable energy source.
The energy stored in coal (and indeed all fossil fuels) is ancient sunlight. This is how it works:-As you know plants need CO2 form the air and sunlight and water to undergo the biochemical process called 'photosynthesis'.Photosynthesis converts the CO2, and Water into sugars which are then used by the plant to make wood and oxygen - the plant grows.You will all be familiar with the fact that wood will burn using the oxygen in the air to produce heat, water and CO2. The heat given off is the sunlight energy that the plant trapped and stored as it 'photosynthesised'. Plants therefore affectively trap and store sunlight as chemical energy.If many plants form a layer and this layer gets covered with soil and buried, the plants turn into fossils and if there are enough of them they form a layer of biological matter. Time and heat in the earth turns this biological matter into coal (and oil and gas).The coal, oil or gas will burn in air to produce heat, water and CO2. The heat is the sunlight that the plants trapped when they were living all those millions of years ago - fossil sunlight!------------------------------------------------------------------------------------------------------Coal contains (stores) chemical energy in the form of Carbon/Hydrogen compounds. It contains various impurities as well. When heated, these Carbon/Hydrogen compounds and some of the impurities will react with oxygen producing carbon dioxide (CO2), water, and other chemicals (depending on the original constituents), releasing much of it's stored energy as heat.-----------------------------------------------------------------------------------------------------------
The phrase "the sun on Saturday" is unclear, as it could refer to various contexts such as solar energy production, weather conditions, or metaphorical meanings. If you're asking about solar energy, costs can vary based on location, installation, and energy rates. Please provide more context for a more accurate answer!

Approximately 30,000 kilograms of coal would need to be burned to produce the same amount of energy as is generated by a kilogram of uranium fuel pellet. Uranium fuel has a much higher energy density than coal, making it a more efficient and cleaner source of energy.
In terms of potential energy, one pellet of uranium contains much more energy than coal. It is estimated that the potential energy in one pellet of uranium is equivalent to burning several tons of coal. This is due to the high energy density of nuclear fuel compared to fossil fuels.
One third of coal's energy reaches the consumer.

Coal produces around 24-33 megajoules of energy per kilogram when burned. The energy output can vary depending on the type and quality of the coal.
To release the same amount of energy as one kilogram of uranium undergoing nuclear fission, approximately 3.6 metric tons of coal would need to be burned. Uranium undergoes much more efficient energy release through fission compared to burning coal.
You can use many different things. some examples are: Bio-Fuel (still in development) Wind (not as reliable as coal) solar (doesn't produce as much energy as coal) hydro (doesn't produce as much energy as coal)
The amount of energy generated from coal can vary based on factors such as the type and quality of coal, the efficiency of the power plant, and the technology used. On average, coal-fired power plants convert about 33-40% of the energy in coal into electricity.
Depends on the amount of electrical energy they (need to) generate. How much does the average nuclear plant generate ? How much does the average coal plant generate ?
The same as you would calculate for any other substance. You have to multiply all of the following: • The desired temperature difference. • The mass of the sample. • The specific heat, in this case, of coal.
1 kg of U-235 will produce as much energy as 1500 tons of coal
