Will power fail if electric cars take to the streets of Brazil?

“We rained in the wet” when we say that 2020 was a harmful year for many sectors, but some data bring some encouragement to the country. This is the case of our national energy matrix, which, according to the Ministry of Mines and Energy, is represented in 83% from renewable energy sources – hydroelectric, wind, biomass, solar and biogas.

In this context, the solar energy market accelerated in a very visible way in Brazil last year: a survey by the Brazilian Association of Photovoltaic Solar Energy (Absolar) reveals that the power generation system has tripled its activity in one year, with growth of 45% in the last semester. At the same time, the sale of electric cars around here has also started to pick up pace.

But would we be “without electricity” or would we pay more for it if our fleet of passenger cars migrated from fossil fuels to electric energy?

The agenda of the national energy matrix permeates the discussions of many segments, such as electric vehicles, which we have been looking at here at TecMundo in recent weeks. It is normal to have doubts, myths and truths about the subject and we cannot be frivolous.

The fact is that not only do the conditions exist for this modal to prosper in terms of infrastructure, we already see an expansion

In other words, Brazil has viable means of expanding its fleet of electric cars, powered by solar stations and derivatives, without this causing a collapse in our energy system. In all, we have 3 GW of installed power on solar panels on the roofs of homes and businesses, with 255 thousand photovoltaic systems that supply energy to 400 thousand consumer units – according to the Brazilian Association of Distributed Generation (ABGD).

Clean and safe energy

Also according to data from the federal government on our energy outlook in 2020, the Brazilian matrix is ​​led by hydropower (63.9%), followed by wind (8.6%), biomass (8.4%) and solar (1.4%).

In 2019, Brazil exceeded the goal of installed capacity – total energy that can be produced, according to inspection by the National Electric Energy Agency (Aneel) – with an increase of more than 7 thousand MW. In total, we have more than 170 thousand MW of inspected power. For André Pepitone, general director of Aneel, this result guarantees the security of energy supply in the country.

The participation and growth of solar and wind energy in this scenario are also welcomed by the agency. “The greatest potential for growth is wind and solar, especially in the Northeast region. In terms of thermal energy, one third comes from sugar cane bagasse, ”explained Pepitone, in an interview with Highland, news portal of the federal government.

It is also worth noting that the sources of renewable energy available in Brazil are expanded and fostered by the socioeconomic aspect, the generation of jobs and income for the population, in addition to the environmental and technological factors involved.

Tax breaks

With more competitive prices, due to the reduction in the cost of installing solar energy in Brazil, which has fallen by more than 90% in the last decade, the generation of solar panels grew 58% in 2020 compared to the previous year, according to Absolar.

For 2021, the sector expects even greater growth if the bill 5829/19 is approved (it is in an emergency regime at the Federal Chamber), which would guarantee a 100% discount on charges and tariffs for the use of transmission systems and distribution to micro and mini solar energy generators.

Tropicality and ample solar lighting in practically the entire Brazilian territory are also geographic attractions that put us ahead of other countries.

In an onslaught in the housing and civil construction sector, Absolar is also looking for the installation of photovoltaic panels in the homes of the “Casa Verde e Amarela” program, announced in August by the federal government to replace “Minha Casa, Minha Vida”. But in this case, the project has yet to be converted into law by the president and actually start functioning – which we hope for.

For Rodrigo Sauaia, president of Absolar, the solar source may have a strategic role in the resumption of the Brazilian economy after the pandemic, attracting private investments in the billions of reais, generating jobs, strengthening the collection of public power and alleviating energy costs electricity for consumers. I make your words mine when Sauaia says that “solar energy will also continue to help fight climate change”.

We must not forget that this is the greatest challenge of the 21st century, for our and future generations.
