Sustainable energy is an economy for the present and a responsibility for the future. Know more!
Sustainable energy is all that is obtained through renewable and sustainable sources. In other words, when generated, energy does not create major negative impacts for the environment and for society. In recent years, the planet has shown signs that something needs to be done. Climate changes, such as rising global temperatures and rising sea levels, show how urgent it is that new alternatives, especially in the energy sector, begin to be practiced.
In Brazil, clean energy has been gaining support. According to data from the Ministry of Mines and Energy (MME), 82% of the electricity generation matrix is represented by renewable sources. This is a positive indication, but there are still many changes necessary for the maintenance of the planet. Understand the theme better, reading the content until the end.
What is sustainable energy?
Sustainable energy is energy that comes from natural resources and is replenished naturally, such as the sun, wind, movement of the tides, strength of the waters. At the beginning of resource exploration, oil and its by-products were the most used options.
However, over the years, it has been realized that the burning of these fuels contributes to global warming, in addition to being a finite resource. In this way, sustainable energies are necessary both to maintain the energy capacity of countries, as well as to promote sustainability.
One of the obstacles, which still hinder clean energy development, is that traditional sources generate greater electrical capacity than alternative sources. For example, the nuclear plants in Brazil, Angra I and Angra II, have a production capacity equivalent to 2,000 solar plants. In addition, the amount of renewable energy sources available in countries is not equivalent and most of them are presented in an alternate way, such as sunlight and the strength of the winds.
Therefore, to maintain the current demand and to cope with the new demands that arise as a result of development, it is still necessary to use traditional sources, such as oil and nuclear energy. However, the development of technology and the promotion of investments in renewable sources must be a priority for countries that wish to develop.
Why is it important to invest in this type of energy?
One of the main reasons for investing in sustainable energy is the reduction of pollution and mitigation of global warming. The secretary-general of the United Nations (UN), called on countries to stop financing the coal sector and commit to reducing the use of fossil fuel. According to the report of the Greenhouse Gas Emissions Estimation System (SEEG), Brazil reduced the emission of greenhouse gases by 5% from electricity generation. This decrease is mainly due to investments in wind and solar energy generation.
In just two years, the number of solar panels installed in Brazil increased by 560%. In other words, both the population and companies are beginning to become aware of this change and are investing in sustainable options. This shows that the country is moving towards sustainable development, opting for clean energy sources.
Therefore, we can conclude that investing in sustainable energy is necessary for the preservation of the planet. The solution lies in the diverse use of renewable energy sources, using them in a complementary manner, according to seasonality and intermittency characteristics. In Brazil, both solar and wind power are abundant and have been gaining prominence and investment by the government.
