With the increase in awareness about the depleting natural resources, the lookout for new, renewable, and cleaner energy sources has also gained pace.

Solar energy is one of the main sources of renewable energy. Being clean and free of cost, it can be utilized easily to generate energy. Solar panels are used to harness the sun’s energy, but it does not come without any pros and cons.

Advantages of Solar Panels

1. Accessibility

Solar panels allow you to obtain energy from an alternative source rather than the main power grid. This eliminates the need of having long power lines running to your home. This can prove to be especially beneficial for houses that are located in far off areas.

2. Long-term Efficiency

Once installed, solar panels can make up for their initial installation investment as they do not require any extra fuel to work. This means that you can rely completely on solar panels and see a return on their investment immediately, with no more electric bills. Solar panels also require very little maintenance.

3. Incentives

There are several federal and government incentives available that are offered to those who plan to install solar panels on their homes. This is available in the form of tax credits for homes and businesses. Solar panels also tend to increase the value of a home or business.

Disadvantages of Solar Panels

1. Positioning

It is important to place solar panels in an appropriate place where they can receive the maximum amount of energy from the sun. Solar panels have minimal efficiency in cloudy areas, and can also be less effective in areas where there is heavy tree cover.

2. Initial Expense

The initial cost of installing solar panels can be quite high. Studies show that extensive use of solar panels in homes may not yet be a financially suitable option due to their high costs.

3. Impact of Geography

Rather than depending on the strength of the sunlight they receive, solar panels tend to rely more on the number of hours in the day that the sun is out. Thus, solar panels are less efficient in places closer to the poles.

Tidal Energy is a natural source of energy, but it has some prominent following advantages and disadvantages:

Advantages of Tidal Energy:

• Tidal power is free.
• It have no greenhouse gas emissions and no other wastes.
• Don’t need any fuel.
• Reliable electricity production.
• Its maintenance is not highly expensive.
• Tides are always predictable.
• Offshore turbines and vertical-axis turbines are costly but not costly to built, also that it has positive impact on environment.
• Its renewable energy. The tides will continue to ebb and flow, and will produce the power.
• One tidal plant after implementation can produce energy for 75 to 100 years.
• For generating power,  it uses cheapest source as fuel which is water.
• Electricity production is reliable through tidal nergy.
• It protects the coastline against the damage from high storm tides and provides a ready made road bridge.

As long as as moon exists, earth revolves,nothing can stop tidal flows.

Disadvantages

• It causes a constant loss of mechanical energy in the earth-Moon system.
• Energy loss causes the earth to slow in the 4.5 billion years, since formation losing 17% of its rotational energy.
• It may take extra energy from the system which will increase the rate of slowing it over the next millions of years.
• Similar effects are on large dams; it affects the flow of saltwater in and out of estuaries. This will change the hydrology and salinity, and can create negative affects on the marine mammals that use the estuaries as their habitat.
• When smaller volume of water exchanges between the basin and the sea, the turbidity decreases.
• It decreases the salinity inside the basin which also affect on the ecosystem.
• The barrage which is build across an estuary is so much expensive. But that barrage affects a wide area and change the environment for many miles downstream and upstream. Usually it harms the coast birds because they get food from the mud which is uncovered by tides.
• It provides power only for 10 hours a day. And that’s only when the tides are moving in and out.
• Tidal energy only produces 7% of electricity in England. Which means very few population can use this free energy while paying lot of money for other types of electricity.
• The mud flats and destroys the living animals and birds on it.
• As the water can not flow away so all the dirt and pollution ligers around the coast.
• It disrupts the creatures’ migration in the ocean.
• A lot of maintenance is required for barrage systems for their salt resistance parts.
• The people who rely on fishing are affected by it.
• Like other renewable energy and conventional power generation it’s so much expensive.
• Its maintenance is complicated because of sea-basing generation facilities.
• It destroys the ecosystem at the bay.

Human’s curiosity leads towards invention, like utilizing energy from sun and generating electricity. This is a renewable form of energy and is an unlimited resource unlike other resources to generate electricity. This discovery further leads  to invention of appliances and instruments that uses sun rays to generate electricity and when applied  to a large scale  it results in creation of solar power plants.

What is a solar power plant?

A solar power plant captures the sun rays and convert photons into electricity. A solar semi-conductor possess electrons and the  sun ray contains photons. As a  photons  enter  this semi-conductor, these photons are captured and the electrons are transformed into electricity. This mechanism depends on the nature of material being used as semi-conductor.

A solar power plant contains large number of solar panels, that are connected to each other. Basically these panels are electricity generator and generate electric pulses. The electricity produced is then used domestically or for commercial purposes depending on the demand.One can construct a mini power plant by arranging number of solar panels and connecting them.

Efficiency of solar power plant

Its efficiency depends on the intensity of sun rays touching the panels. If more rays are touching the panel, you need few panels to generate electricity and vice verse. Many countries located near equator, have constructed their own solar power plant. These countries avail maximum sunshine by taking advantage of their location and thus make it more efficient. But this doesn’t mean that you are restricted by your location.

You can also build solar power plant  in other parts of the world. Since this technology is in its initial stage, new inventions are in process to make this task easier for other parts of the globe.

Disadvantages of solar power plant

One of the issue related to solar power plant is its space. These solar power plant requires huge space and areas because of their huge size. This size goes on increasing as you are installing more and more panels to enhance its capacity. But, in many countries this issue is resolved by installing mini solar plants. Another issue is its initial development cost. There are huge costs associated with this technology, which makes it unaffordable.
