Solar energy – pros & challenges

solar energy - pros & challenges

What is solar energy:

  • Solar energy is created by converting the energy of sunlight into electrical energy.

Pros of solar energy:

  • Solar energy generation does not release greenhouse gases, so there will be no negative effect on the environment. It is pollution-free and clean energy.
  • Solar energy is sustainable energy. So, there will be no problem with using it up completely without leaving it for future generations.
  • Plenty of green jobs will be created by expanding the solar energy industry.
  • There is no need to import fossil fuels like coal for electricity, so it will help the economy in the long run.
  • There is no need to buy the main ingredient because sunlight is free.
  • Solar energy requires investment to set up, but the energy generated is the cheapest electricity. So, many more people can have access to affordable electricity.
  • Off-grid solar systems ensure power supply even in disaster-hit areas. Off-grid means buildings designed to be independent without depending on public electricity and water lines.
  • Electricity generation from fossil fuels requires large quantities of water. Solar energy production does not require water. So, it saves water. Moreover, this makes solar energy more reliable. Power generation will not suffer even in times of drought.

Challenges:

  • Large scale solar power generation requires a large area of land.
  • At present, solar cells utilize only a small percentage of sunlight. Increasing solar cells efficiency is a big challenge. Moreover, when the efficiency is increased, the amount of land required will be reduced.
  • Solar energy production facilities need a huge investment to set up.
  • Not every region in the world receives enough sunlight to depend on it fully.
  • Ensuring power supply in the night times when there is no sunlight requires storage.
  • The clean energy industry is facing a skilled labour shortage. Training a lot of people for the required skill set to match the growing solar industry is another challenge.
  • Solar cell manufacturing requires toxic chemicals such as sulfuric acid, hydrochloric acid etc. Developing efficient solar cells using less toxic chemicals is a big challenge.

Conclusion:

Leveraging solar energy will result in energy transformation from fossil fuels to clean and sustainable energy. It also helps in fighting against climate change. Government should provide subsidies and widespread awareness to encourage roof-top solar grids and solar farms so that everyone will have access to cheap and clean energy.

  1. The way of solar energy is very appreciated onething. Because it was very low minus point and many positive points. In future,if a solar car will come instead of fuel vehicles, it will be the best thing. That’s only help to decrease our environmental pollution and close the ozone layer.

    1. Only solar car can’t control pollution , therefore all vehicles should be solar energy operated but this is not possible because in bike can’t install solar system due to needed more space and for heavy vehicle big solar system needed due to which price of vehicle increase.

      1. Yes, we cannot setup entire solar energy in a bike considering the space required but we surely can introduce a chargeable battery operated bikes just like the electric scooter we have. But this alone is not the end of the solution, there are a lot of things that technology has to do its part to make two wheelers run for long distances. The day is not so far that we all will be witnessing electric vehicles and bikes running on road in huge numbers keeping in check the pollution.
