Solar Energy on the Rise As Brazil Diversifies Energy Mix
Solar energy is on the rise in Brazil as the country’s latest national energy auction attracted 400 applications for photovoltaic (PV) plant development.

Brazil’s energy auctions invite all forms of energy development to bid for government power supply contracts.
This year is only the second time that solar has been included in the auction and the first time a specific category has been created for PV projects.
Solar energy developers have applied to sell power from 400 power plants across the country in the auction to take place Oct. 31.
That represents 10.79 gigawatts of capacity, according to Brazil’s energy research agency Empresa de Pesquisa Energetica.
Also registered were 626 proposed wind farms and eight biogas projects.
“We expect the government will buy 1 gigawatt of solar energy in the first auction,” Pedro Vaquer, director of the Brazilian developed Solatio Energia told Bloomberg.
Brazil currently gets less than 1 percent of it electricity from solar power but the government aims to diversify the country’s energy mix.
The country also has strong sunlight, with an average irradiation rate almost double of Germany, the world leader in solar installed capacity, but installed solar capacity is currently well below 100 megawatts (MW).
Brazil’s power auctions see the government set a ceiling price, and developers bid down the rate at which they are willing to sell power.
The lowest offer wins long-term contracts to sell electricity.
While solar projects have participated in past auctions, they have previously had to compete against cheaper power sources such as wind and won no contracts to sell electricity.
October’s auction will see developers compete for 20-year contracts from solar plants of at least 5 MW.
The ceiling price has yet to be announced by analysts but industry experts expect to see a price of 220 to 250 reals ($96-109) a megawatt-hour.
They expect to see around 500 MW of solar capacity being purchased.

The human-caused climate crisis could cause the extinction of 30 percent of the world's plant and animal species by 2070, even accounting for species' abilities to disperse and shift their niches to tolerate hotter temperatures, according to a study published this week in the journal Proceedings of the National Academy of Sciences.

For years, Toni Genberg assumed a healthy garden was a healthy habitat. That's how she approached the landscaping around her home in northern Virginia. On trips to the local gardening center, she would privilege aesthetics, buying whatever looked pretty, "which was typically ornamental or invasive plants," she said. Then, in 2014, Genberg attended a talk by Doug Tallamy, a professor of entomology at the University of Delaware. "I learned I was actually starving our wildlife," she said.

The latest science shows how the pace of sea level rise is speeding up, fueling fears that not only millions of homes will be under threat, but that vulnerable installations like docks and power plants will be overwhelmed by the waves.
