To find substitute sources of energy world has determined to follow renewable energy. However renewable energy have their few advantages as well as disadvantages.

Available renewable energy sources, which we have, include are solar, hydro, geothermal, wind, ocean and biomass. Most ordinary advantages of these is that they are fresh energy sources also do not pollute air. One ordinary disadvantage is, it is not possible to produce big quantities of electrical energy than can be completed with the fossil fuels. As they are latest technologies and the costs of them is also very high.

Solar energy utilizes energy from sun. It has some benefits since these systems can simply fit in the existing buildings plus do not have an effect on land use. Natural features control solar radiation and it is limited to daytime and non-cloudy days.

Hydro energy uses water to produce power and it is most reliable source of all energy that is renewable.

Some of its disadvantages are it affects ecology plus cause downstream troubles. Decompose of vegetation on riverbed can cause an increase of methane that contributes to greenhouse effects. Dams might also cause alteration of natural river flow also affect natural world in area. Water that is colder and is lacking in oxygen will release into the water and this kills fish, sudden free of water might result in flooding.

Geothermal energy uses steam from Earth's ground to produce power and uses smaller land region with other kinds of power plants. And they can run continuously throughout a year. Disadvantages are inclined that these power plants are site exact and it raises toxic chemicals plus heat from earth while it tries to get the steam.

Wind energy uses power of wind to create electricity. Wind turbines are considered to be large and the areas below them can be used for farming. These turbines are very loud to operate as well as they intimidate the population of the wild birds as well.

Ocean energy tends to be costly and to access this energy you require 40 degree Fahrenheit disparity in water temperature all through the year.

Biomass electricity is made from energies of wood, agricultural plus municipal waste. It helps to save landfill waste but transportation is expensive and will affect diversity of land. But the process is fairly complex and must be simpler.
