Brazil's ranking in clean energy rises

Brazil's ranking in clean energy has been on the rise. With nearly half of its energy supply coming from renewable sources, Brazil is increasingly becoming a positive model that aligns with the rest of the world.

According to figures released by the UN’s Intergovernmental Panel on Climate Change (IPCC), up to 77% of world energy demand by 2050 is potentially expected to come from renewable energy sources, although the current figure is 13%. The figure for Brazil has reached 44.8% in 2010 and is expected to rise to 46.3% by 2020.

Demand for energy in Brazil is growing. In the next decade, Brazil’s demand for energy is expected to increase by about 60%.

However, Brazil also promised to reduce its CO2 emissions by 36% to 39% by 2020, making it a country dedicated to the development of clean energy.

The energy research company EPE, which is engaged in research by the Brazilian Ministry of Mines and Energy, announced in late September 2011 that the 10-year energy plan shows that Brazil needs 190 billion CRUSSELS (122.6 billion US dollars) of investment to meet the challenge. Among them, 100 billion cruselo (about 63.8 billion US dollars) will be used to promote renewable energy projects that have not yet been signed, 55% for large-scale hydropower, and 45% for wind, biomass and small hydropower.

In Brazil's electricity sector, 83% of its demand has been achieved from renewable energy sources. It was recognized by the Pew Environment Group in Washington and considered the lowest carbon power grid in the world. one.

Brazil currently uses only 560 kWh of electricity per person per year. This compares with 1900 kWh in the United Kingdom and more than 4500 kWh in the United States. However, facing continuous development, Brazil now needs to increase its grid settings from 110 GW at the end of 2010 to 171 GW at the end of 2020.

1. Hydropower currently has the largest share of large hydropower in meeting Brazilian demand. According to the 10-year plan, the installed capacity of these facilities is expected to rise from just 85 GW to 115 GW.

The main new hydropower project is the construction of 11,233MW of the Belo Monte dam on the River Xingu in the Pará province of the Amazon River, which will generate electricity by January 2015, in 2019. January full investment. This will provide enough power for 18 million families, that is, more than 60 million people.

More than half of the investment in Brazil’s 10-year energy plan will be for hydropower.

2. Wind Power Although there are settings for Belo Monte and other hydroelectric power stations, the share of Brazil’s electricity supply from hydropower is expected to decline from 75% in 2010 to about 67% in 2020.

At the same time, other renewable energy sources, such as biomass, small hydropower stations, and wind power in particular, will double from 9GW in 2010 to 27GW in 2020. This will enable them to contribute to the nation’s electricity supply from 8% to 16%, and maintain the overall contribution of renewable energy to electricity at 83%.

So far, the biggest increase in contribution will come from wind power generation. At present, wind power supplies about 1% of Brazilian electricity, but according to the current plan, it will supply 7% by 2020.

Although it has a coastline of 9,650 kilometers of the Atlantic Ocean, and most of its northeastern part is the most powerful and stable wind source in the world, Brazil achieved only 1 GW of wind power in May 2011.

According to the EPE plan, this figure is expected to reach 12 GW by 2020. However, the Brazilian Wind Energy Association considers this forecast to be very conservative. The Brazilian Wind Energy Association stated that, in fact, it is expected to exceed nearly double and it will reach approximately 22GW.

When the first wind atlas of Brazil was published in 2001, the country’s wind power potential was estimated to be 143 GW at 50 meters. 80 to 100 meters of new measurements show that the true potential is actually 350 GW.

Compared with the country's total power generation capacity of 113 GW at the end of 2010, it also means that Brazil's potential for wind power generation is greater than the hydroelectric potential, and the potential for hydroelectric power generation is estimated at 261 GW.

There are currently 51 wind farms in Brazil, and more than 30 are under construction. However, in the near future, this figure will definitely increase dramatically. By 2013, 25 billion Keroxel will be invested in wind power projects (16.1 billion U.S. dollars).

3. Bioenergy Another key element in Brazil's energy needs is ethanol. According to EPE, ethanol will play an increasing role due to the increase of national flexible fuel vehicles that can use gasoline, ethanol, or any mixture of the two. .

According to the report of the 2010 Pew Environment Group, Brazil currently has the second largest biofuel market in the world, and through further expansion, it ranks first in available resources.

The national fleet of cars, trucks, and buses is expected to double from 29 million to 56 million within the next decade, and the demand for ethanol is expected to nearly double from 27 billion liters to 73 billion liters.

According to reports, about 50% of Brazil’s oil production will be exported by 2020, which is due in large part to the continued rise in the use of ethanol in the domestic market.

EPE predicts that Brazil will be the first oil exporter in the world with a very significant renewable energy structure.
