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.
Solar energy is not the main source of energy for several reasons: it can be intermittent and dependent on sunlight, which limits its reliability; the initial installation cost can be high; and large-scale storage solutions are still being developed to address the intermittent nature of solar energy. As technology advances and costs decrease, however, solar energy is becoming more competitive and feasible as a primary energy source.
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.

What is the main source of solar energy?
The main source of solar energy is the sun. Solar energy is generated by the sun's nuclear fusion reaction, which releases energy in the form of electromagnetic radiation, including light and heat. This energy reaches Earth in the form of sunlight, which can be harnessed using solar technologies for a variety of applications.
What is the main source for solar energy?
The main source for solar energy is the sun. Solar panels use photovoltaic cells to convert sunlight into electricity for various applications, such as powering homes, businesses, and vehicles. Solar energy is a renewable and sustainable source of power that reduces reliance on fossil fuels.
Is a solar cell an energy source?
No, a solar cell is a device that converts sunlight into electricity. It is one component of a solar energy system that utilizes the sun as an energy source.
What is the main source of energy for our planet is?
The main source of energy for our planet is the sun. Solar energy drives processes such as photosynthesis in plants, which in turn form the basis of the food chain for all living organisms on Earth.
What is the main source of all energy?
The main source of all energy on Earth is the sun. Solar energy is converted by plants through photosynthesis into chemical energy, which is then transferred through the food chain to provide energy for all living organisms.
