Conventional forms of energy generation like natural gas, coal, oil and nuclear are finite but still account for the majority share of the energy market in term of capacity and utilization. On the other side, the renewable energy sources such as solar, wind, tidal and geothermal energy are sustainable, and due to their presence in ample quantity, they can compete with non-renewable energy sources.

Among renewable energy, the solar energy is obtained from sunlight and converted into electricity or thermal energy, the rotation of wind turbine by wind produced electrical energy, the conversion of energy from running water into electricity. They are actively evolving technologies to turn natural resources or alternative energy into less loss of intensive electricity. These power plants have their own collection of feature, specification, pros and cons. They can be measure on the basis of a few matrices which are in the following:

Solar power plants: 

• Solar power plants transform electricity from the light to thermal or electrical energy as solar photovoltaic (PV) cells capture the sunlight along with one of the cleanest and most available green energy sources.
• Solar PV requires very less maintenance in order to function and can last for about 25-30 years.
• This has been the most effective non-conventional energy source which offers environmentally sustainable and is accessible in abundance.
• The initial cost involved the full setup of solar power plants is fairly high, and the deployment of solar power system involves a great deal of area.
• The main disadvantage of solar energy is the collection during rainy days. The efficiency of a solar system drops as they are totally dependent on sunlight.

Wind power plants: 

• Wind power plants use wind turbine for the production of electrical energy. They are also very efficient in the production of renewable energy.
• There is no environmental damage, seeing as fossil fuels are not burned to produce electricity.
• The operational cost of maintaining wind power plants are very low after the wind turbine have been erected and are normally deemed cost-effective.
• Wind farms also can be constructed on agricultural land, without the cultivation activities being interrupted.
• On the other hand, maintenance of wind turbines can differ, as some need regular examination, and wind turbine ventures usually involve big capital expenditure.
• However, wind energy has the same downside to solar energy because it is not constant. Although the wind is relentless and will never run out, but the pace of wind may change. And in result, it can cause severe complications mostly to the efficiency of the wind turbine.
