Adventages & disadventagesof solar energy commuity,the state & counrty as a whole body.?

Answer 1

Are you asking what would be the advantage to the country completely converting to solar power?

That is a big one.

There are a couple of big advantages. First is it is pretty much free power. The sun shines and we don't have to do anything to make it happen. Joy. Also, it is clean energy. It does not have any chemical or radioactive releases into the environment.

Disadvantages. It is expensive. To build a solar power plant requires a lot of money and resources. It also requires a lot of money to maintain it. Also, the amount of solar power plants that would have to be built to match the output of the other electric sources is monumental. Next up is the environmental damage that these plants will do. A lot of land will have to be given up so that the solar power plants can be built. That means destroying habitats. There would be thousands of acres destroyed to make way for these plants and as the country grew many more would be destroyed to do the job.

At the moment, solar power technology is not there to be able to do the job by itself. That will probably change in the future. Till then, solar can and should be used to augment as much of the electricity production as is feasible. If people added solar panels to their houses then there would be a tremendous gain.

Answer 2

The advantages are numerous. Clean energy. Sunlight is free. Not controlled by a utility company. Independence.

Disadvantages would be the initial cost and cloudy days.

However, the costs for retrofitting an existing building for passive solar can be very reasonable. In fact, I have plans to take advantage of passive solar by putting a skylight in on my south facing wall which already has floor to ceiling windows. For thermal mass, I will be putting a stone floor under the skylight. This will hopefully reduce my heating bill substantially. In addition, I am considering building a trombe wall on the other end of my house along with a passive solar hot water heater for laundry and bathing water.

There are other options to fill in the solar gaps such as wind energy, etc.
