Carbon, coal has a covalent network bond and when burnt these break to release energy, diamonds also have a covalent network bond, however each carbon atom id bonded to 4 others which make it extremely strong.
No. Both coal and diamond are allotropes of carbon, each with a different matrix structure.
when each substance burns, it releases different amounts of energy. this is shown in the colours they emit as the flame when burning. Very high energy is shown by the burning of a purple flame, and it goes down in the spectrum to red, which is the lowest energy flame colour. examples of these are: lithium-red sodium-yellow iron-gold copper-green/blue potassium-lilac

Wind energy is already used to supply some of the electric power that would otherwise be produced by burning fossil fuels. As of 2010, the 8 largest onshore wind farms in the US each have a capacity of more than 450 Megawatt. When the wind blows, those wind farms produce electricity that would otherwise be produced by burning coal or natural gas.

The only thing similar is each produces energy. The coal is the dirtiest form while solar is the cleanest.
The production of uranium in each year is extremely small compared with the production of coal, oil, methane; but the most important is the energy obtained per unity of mass.
not really efficient, the efficiency rate some where about 7-12%, which pretty bad. reasons, turn coal in electricity is not a direct method, but lots of conversions happens and each time there is a significant loss. Burning coal is to get water boiling and all the steam produced is than used to turns the turbines.
These three Rs each help us reduce our use of energy. Energy (electricity) is usually generated by burning fossil fuels (coal, oil and natural gas), which is causing global warming.
According to the US Institute for Energy Research, coal in 2005 was responsible for 26% of global energy production. This percentage is dropping each year as more countries and power plants move to oil and gas, the burning of which releases less harmful carbon dioxide emissions than coal. There is movement too in the establishment of renewable energy power (solar, wind, water, hydro, tidal and wave, geothermal, ocean thermal, biomass and biofuel).
By the early nineteenth century, the harnessing of steam power enabled humans to vastly multiply the energy generated from burning coal, thereby greatly expanding the amount of energy available to humans per capita, that is, to each individual.

Cheap and readily available, high energy value per unit, existing technology
If efficiency is 100%, each Joule of electrical energy is converted into one Joule of another type of energy.
