New sustainable ways of living have been gaining more and more traction worldwide. Concern about the environment's finite resources increases as they run out. Thus, photovoltaic solar energy is an alternative in the midst of chaos: the electrical energy that is produced from sunlight – even on cloudy or rainy days – has very interesting uses, which can be enjoyed in different ways.

Cinesolar is a project that travels around Brazil with a van equipped with solar panels to show Brazilian films to the public free of charge. It began in 2013 and has shown 730 sessions to date. A battery is used to store the energy generated throughout the day, since the sessions take place at night. In addition to showing films, the team promotes other sustainable activities wherever they go, such as eco-graffiti, eco-DJs and the planting of a tree at the end of each session. Monitors inside the van show the amount of energy produced by the solar panel and animations that explain how solar energy works. Solar Trees

Since 2014, in Rosana, in the interior of São Paulo, a set of solar panels have been installed on the surface of the waters of a hydroelectric plant. This is the first floating solar plant installed in Brazil, and it is located on the waters of the Porto Primavera hydroelectric dam. Two sets of panels are arranged – one with rigid modules and the other with flexible modules – each generating up to 25QW of energy. This type of plant is widely used in developed countries, which do not have land to install solar plants. The main advantage is the greater efficiency of the panels, which cool quickly due to their proximity to the water. Solar Powered Boat Competition

The Solar Challenge Brazil is a competition that encourages the development of new technologies and clean, renewable energy sources, such as fuel for mobility. Inspired by the Dutch Frisian Solar Challenge , a Nautical Polo team from UFRJ, the Federal University of Rio de Janeiro, began building the first solar-powered electric boat in Brazil in 2006. Two years later, they competed in the Netherlands and returned to the country motivated to have this competitive modality here. This year, the challenge took place between September 12 and 16, and included 400 students and 20 teachers from several Brazilian states, divided into 16 teams and 18 boats – all equipped with solar panels and batteries. Solar Powered Stadiums

In Brazil, five soccer stadiums have already adopted the clean energy generation method. Large arrays of solar panels were installed at Maracanã, in Rio de Janeiro; Mineirão, in Belo Horizonte; Arena Pernambuco, in Recife; and Pituaçu and Arena Fonte Nova, both in Salvador. Most of the systems were installed during renovations made for the 2014 World Cup in Brazil. The one with the largest solar system is Mineirão, with 6,000 panels capable of generating 1.42 megawatts. The surplus energy goes to the distribution grid, which in this case is CEMIG.
