Historically the humanity has been conditioned to use fossil fuels and its derivatives, but the finitude of this natural resources incentive the development of new types of energy, mainly the renewable ones. In addition, the overwhelming of the atmosphere with carbon dioxide makes this new kind of energy a new hope because is commonly seen as the solution to the environmental problems. As a result, the benefits are considered the only point of view in many discussions about the theme, even though the drawbacks are significant and can be a barrier in the development of some energies like the solar. The benefits of the solar energy are commonly related to the natural resource characteristics, like the abundance and renewable capacity, which distinguish it from the traditional way of collecting energy. It is a common knowledge that Sun doesn’t stop shining, at least for more billion years, which means that the natural resource is not limitable like coal, nuclear energy and also the mineral gas. Also, according to the report of U.S. Department of Energy (2015), “The sun deposits 120,000 TW of radiation on the surface of the Earth, far exceeding human needs even in the most aggressive energy demand scenarios” which illustrates that the potential of this energy is immense if there is the ability to absorb it. On the other hand the benefits also includes the environmental aspects, like the sustainability, the availability all over the world and also the reduced pollution emitted during its production. This three aspects are related with each other in a way that both of them are applicable in the present with many consequences in the future. For example, the sustainability, as the definition says, is the capacity of consuming the actual resources without compromising the future uses. So the association of the correct well distributed ability and less pollutant usage ensures that the environmental conditions remain stable for a few more years. In addition, the solar energy has many applications and purposes, which means that can be used in a residence, or a group of them, and also to maintain a satellite orbiting Earth. The technology associated is also silent, which is a good point when this renewable energy is compared to the others like the turbines of wind energy. It is also a good alternative of energy supply in countries that don’t have natural resources (like water and coal) with the advantage of being distributed and modular, which means that even in severe weather conditions the supply tend to be stable. The economical aspect holds the negative and the positive side that need to be well-balanced to evaluate the situation. In the positive side there are some factors related to the investments subsidized by the Government, which reduces the solar panel costs with fiscal incentive and encourage

The environmental changes on water, air and temperature conditions have effects on the population’s health and as United States Environmental Protection Agency (2010) says “Heat is already the leading cause of weather-related deaths in the United States, with more than 6,300 deaths resulting from exposure to extremely hot weather between 1979 and 2006.” So, the usage of renewable energy tends to reduce the environmental changes by reducing the pollution levels on water and air and improves the health conditions that consequently reduces the health costs to people and the
