Renewable energies is the best option for the future. The fact that green energies do not produce carbon emissions has being used for many environmental organizations to press Governments to implement this kind of energies and to stop global warming. Although renewable energies such as the sun, wind, and tide are environmental friendly, there are some advantages and disadvantages of use them.

One of the main advantages discussed for non governmental(nongovernmental) organizations that worth the implementation of renewable energies is climate change. For example, the use of solar panels and the building of wind farms have been exalted for their benefits supporting until ? 10% of the energies demand in countries such as Denmark, and a very small amount of carbon emissions. (are them?)

The second advantage is related to cost and benefits. Renewable energies are cheap and accessible for almost every country.The benefits, mostly environmental and health benefits are enough reasons for their adoption. Clean air, very low carbon emissions, and potable water improve people health.

Although these advantages, there are some disadvantages highly discussed for Governments.

The first most important disadvantage is related to supply. Many countries are discussing that even though green energies are a good option to stop climate change, they can not cover the current demand for electricity. Highly Industrialised countries such as The United States, France and Japan have a high electricity demand and it is impossible ^ supply this demand with renewable energies with the modern technology.

Another disadvantage to use renewable energies is that not every country is able to use them. Some countries can not use solar power because they are clouded most time of the year; other countries has low availability of wind power. (use".....,while,.....",better?)

In conclusion, despite the great advantages of use renewable energies, mainly for the environment and people health, the disadvantages related with availability and demand supply , make their use at a low scale. More research and technological improvements must be developed to resolve these problems.
