The share of renewables can be 47 % higher in the Brazilian energy matrix , the next 40 years than projected by the current policy of the government. According to the report [ R ] evolution Energy , released on Tuesday ( 27 ) by Greenpeace , the matrix can count on 66.5 % from sources like wind, solar and biomass to feed the electrical , industrial and transportation in 2050 .
When considering only the energy matrix , the projection is even more dramatic : 92 % of the electricity that feeds the Brazil in four decades can be cleaned . Currently , this scenario and the national tradition of this renewable sector are at risk due to wrong decisions of the federal administration , which has embraced dirty sources such as coal .
In its 3rd edition in Brazil , the [ R ] evolution Energy offers a sustainable and clean energy matrix based on available resources and technologies. This scenario addresses the future need for energy for the country and reconcile economic growth with environmental preservation .
The study also demonstrates how the rational and efficient use of energy in buildings , industry and transportation can reduce dependence on fossil fuels . By setting [ R ] evolution Energy , energy demand is 25 % lower in 2050 compared to the reference scenario , even if the GDP grow annually between 2.5 % and 3.7 % .
The paper also outlines ways to reduce CO2 emissions in the country . The proposed package would help to cut 60 % of emissions by 2050 - from 777 million tons per year by the reference scenario to 312 million tons by the proposed scenario .
By 2040 , it is possible to forego the energy produced by nuclear power plants , thermal powered by fuel oil and coal , and avoid the construction of new large dams in the Amazon . It is also possible to grow without exploiting unconventional reserves of gas and oil, such as shale gas or the pre -salt .
To make this happen , the [ R ] evolution Energy provides a significant increase in the use of renewable sources - will be 396 gigawatts of installed electricity in 2050 , mainly through sources such as wind , solar photovoltaic , solar heliothermic , biomass and small hydro .
In terms of investment , building fewer power plants and the highest share of renewable save R $ 1.11 trillion by 2050 . That's because , despite a larger investment - R $ 2.39 trillion by 2050 , U.S. $ 690 billion more than the government intends to spend in the same period - the economic advantages are evident when putting in mind the high spending on fossil fuels provided in the reference scenario . After all , wind and sun are free , unlike gas and fuel oil.
For the transport sector , the scenario foresees the need for a radical change of the modal - now very focused on the use road and car - for transport by rail and collective. Also the industry needs to adopt stricter standards of efficiency with smaller vehicles and engines that consume less fuel . Renewables account for 40 % of fuel consumption in the transport sector by 2050 . The share of electricity will reach 7 % in the same year .
" It is technically and economically feasible to meet the growing energy demand of the country so clean and sustainable . And in this sense, the energy revolution is a public provocation , because everything depends on political will and vision , "says Ricardo Baitelo , campaign coordinator of Greenpeace's Climate and Energy in Brazil .
" The imminence of a climate crisis poses unprecedented challenges to all nations . There is a strong global movement to reduce dependence on fossil fuels and increase the share of renewable energy , "said Sven Teske , renewable energy director at Greenpeace International .
"Brazil has plenty of natural resources to become a clean energy superpower . Unlike what happened in the past , renewable energy - especially solar photovoltaic and wind power - are more competitive than coal and still use local resources and create more jobs . Use more renewable energy is now more an economic boon than a burden and reduces dependence on imported fuels , "concludes Teske .
