Because coal is plentiful and cheap, and there are plenty of coal plants around to burn it. There are many workers making their living by mining, processing, and shipping coal. To change to sunlight and wind will displace these workers (necessitating re-training), and it will inconvenience some pretty rich and powerful people. Also, solar is not cheap to install, and the wind is inconsistent. Power companies like to be able to control their output.
Major draw back for Solar energy especially in Photo Voltaic type is the cost. With progress efficiency, the cost per unit still keep rising. A solar thermal plant in alternative can be made at reasonably cost competitive but was limited to economy of scale to be in a large size.
Both Photo Voltaic or Solar Thermal plant also share common draw back on energy storage. Solar thermal can only operated during day time and not work well with cloudy sky so it require power back up over the night or cloudy day. Storing electricity using battery is very expensive. Solar thermal could store energy in the form of molten salt (thermal energy storage) but that is only for short term.
If the solar energy plant would be put to use in large scale, it would require a back up power plant either from Hydropower, Biomass power, geothermal power or a nuclear power.
Because they are expensive to instal. In the UK about £15,000 (thats $22,000) to produce an average 2.5 kW, and of course nothing after dark. Unless heavily subsidised the economics do not make sense.
Nuclear fission is main source of solar energy,
The nuclear fission on the sun is the main source for solar energy. This radiation strikes the earth where it is captured by photovoltaic (PV) panels, or focussed on a Solar Tower. Both methods produce electricity, which is clean and renewable.
A solar cell is not an energy source, but an energy converter. In the case of solar, the energy source is light, and the solar cell converts it from light energy to electrical energy.
what is a better source nuclear or solar energy.
no its a renewable source of energy
Nuclear fission is main source of solar energy,
solar energy
solar energy
There is one source of solar, the sun.
the sun
Solar radiation.
Solar energy is from the Sun and the Sun is the main thing for heat energy and light energy.The sun is the source of solar energy and it is heated from the SUN.

solar light is the source of energy for a solar light
The main source is fossil fuels, but their energy is actually stored solar energy from long ago plants. The vast majority of energy expressed on the planet comes from the Sun.
Sun is the source of solar energy. Heat is present in solar energy.
