1. INTRODUCTION

This study aimed to analyze the energy sector in Brazil and recent government policies

for energy from the perspective of sustainable development. In this sense, the sectors

surveyed were electric, petroleum and natural gas in Brazil to assess their performance

in the recent period and its scenarios for 2030 and 2050. The research included the

analysis of various publications cited in the bibliography, highlighting among them the

National Energy Plan (PNE 2030) prepared by the Ministry of Mines and Energy and 3

studies undertaken by Greenpeace [R]evolução energética- Perspectivas para uma

[R]evolução energética- A caminho do desenvolvimento limpo ([R]evolution energy-

The path of clean development) and Investimento em energias renováveis pode gerar

economia de US$ 180 bilhões por ano (Investment in renewable energy could generate

savings of $ 180 billion per year). The analytical framework used was the model of

sustainable development that applied to the energy industry would aim to meet energy

demand without compromising the nature and without depleting its natural resources, to

bequeath them to future generations.

The energy sector in Brazil is facing at the moment with two giant problems. The first

relates to the need to reduce consumption of petroleum products to reduce CO2

emissions and contribute to the fight against global warming to avoid catastrophic

consequences. The second relates to the supply of electricity in the country which will

involve the construction of several large hydroelectric dams in the Amazon region with

its environmental impacts on the Amazon forest and the indigenous communities living

there, in the deployment of four nuclear power plants with all the problems associated

with security and final disposal of nuclear waste and the deployment of conventional

power plants using coal, petroleum products and natural gas which will result more

CO2 into the atmosphere with harmful consequences from the point of view of global

climate change. Solving these problems requires finding substitutes for coal, petroleum

products, natural gas, hydroelectric large Amazon region, nuclear and conventional

power plants.

To avoid the aforementioned problems and promote sustainable development of the

energy sector in Brazil, the results of this study point to the need to adopt a new energy

policy strongly based on renewable energy. This proposed new energy policy is

supported in studies of Greenpeace [R]evolução energética- Perspectivas para uma

energia global sustentável ([R]evolution energy-outlook sustainable global energy) for

the electric sector in Brazil and the author's own studies encompassing all sectors of

energy (electric, petroleum and gas natural) of Brazil.

2. THE ENERGY SECTOR IN BRAZIL

Brazil is the 10th largest energy consumer in the world and the largest in South

America. Government agencies responsible for energy issues in Brazil are: 1) National

Energy Policy Council (CNPE) who has the authority to propose to the President of the

Republic national policies and measures for the sector, 2) Ministry of Mines and Energy

Page 3: A sustainable energy policy required to brazil

3

(MME) that creates standards, monitors and evaluates federal programs and policies to

deploy the energy sector; 3) Departments of Energy Planning and Development

(Electricity, Petroleum, Natural Gas and Renewable Fuels), 4) Energy Research

Company (EPE) which aims to provide services in the area of studies and research to

support the planning of the energy sector.

The Brazilian government has the regulatory agencies ANEEL (Brazilian Electricity

Regulatory Agency) and ANP (National Agency of Petroleum, Natural Gas and

Biofuels), besides having the National Nuclear Energy Commission (CNEN) and the

National Department of Mineral Production (DNPM). The energy sector also has

Petrobras, mixed economy company, which is a publicly traded corporation, with

operations in 30 countries, leader of the petroleum sector in Brazil, occupying the third

position in the world market energy companies, and Eletrobras that is a mixed economy

company publicly traded, which operates in the electric markets and supports strategic

programs of the government, as the Incentive Program for Alternative Sources of

Energy (Proinfa), the Program National Universal Access and Use of Electric Energy

(Light for Everyone) and the National Program for Energy Conservation (Procel).

2.1-The electric sector in Brazil

For many years, especially prior to the 1990s, the state had in Brazil what might be

called a monopoly in the electric sector. That is, the State exercised exclusively, the

production, transmission and distribution of electricity. However, from the beginning of

the 1990s, there was a substantial change to the policy of privatization of the electric

sector. This privatization process had its beginnings during the government of Fernando

Collor, but was extended by subsequent governments, Itamar Franco, Fernando

Henrique Cardoso and Luiz Inácio Lula da Silva. This process occurred through the

guidelines established by the National Privatization Program (PND) that it intended to

transfer to private sector management of the activities that the public sector did not

operate effectively.

After almost 20 years since the beginning of the privatization of electricity distribution,

the balance of what was promised and what is actually happening in the country, allows

identifying the existence of many faults in electric power supply in several regions of

Brazil. Since 1995, the distribution of electricity is operated by private enterprise. The

distributors manage the concession areas with the obligation of maintenance, expansion

Page 4: A sustainable energy policy required to brazil

and provision of adequate infrastructure, and its revenue from charging fees to their

customers. The promises that the private sector would improve the quality of services

and the adoption of affordable rates for all citizens were misleading promises.

The practice has not shown that the management of the electric sector by private

companies is always superior to public companies. Since 2006 there has been, in most

companies, a declining trend of the indicators of quality of services due to its

deterioration, reflecting negatively to the consumer. Recent blackouts Brazilian

electrical system can be attributed to four factors: 1) lack of adequate coordination of

the protection system that has not been able to isolate the problem in the affected area

by preventing the spread of blackouts in the three regions of Brasil, 2) lack of double

protection system in critical areas that can be triggered in the event of faults in the

electrical system, 3) lack of adequate maintenance service to minimize the occurrence

of faults in the electrical system, and 4) lack of systems for emergency power supply in

critical areas that can be triggered when the blackout happens in Brazil's interconnected

power system.

The electricity supply by source in 2009 is shown in Figure 1. The analysis of this

figure reveals that 82% of the electricity supply was hydroelectric and biomass, while

the non-renewable energy sources accounted for 18% of the total.

Mines and Energy of Brazil (MME) provides for the expansion of the electricity sector

by 2030 with the use of energy sources described below: 1) Renewables-191.35 GW

(92 GW existed in 2010), 2) Conventional thermoelectric-21.5 GW (16 GW existed in

2010), and 3) Nuclear- 8 GW (2 GW existed in 2010). 1 GW = 1 Gigawatt = 1,000,000

KW of power. Renewable energy is derived from those natural cycles of conversion of

solar radiation, the primary source of almost all energy available on Earth and therefore

are practically inexhaustible sources such as hydropower, solar, wind and biomass,

unlike sources non-renewable energy such as petroleum, coal, natural gas and nuclear.

Figure 2 shows that in 2030, the PNE 2030 considers the use of new energy sources

(wind, sugarcane biomass cogeneration and waste), besides the increase of coal and

nuclear sources in relation to the situation in 2009. The share of hydropower remains

the same for 2009.

Figure 2- Domestic supply of electricity by source in 2030 (%)

Source: PNE 2030

For these reasons, large hydropower will continue to be the main source of energy in the

electric sector expansion accounting for 77% of total capacity to be installed by 2030.

The priority given to large hydro in Brazil follows the tradition adopted from the

implementation of the interconnected electric system in the 1960s to favor the use of

large hydroelectric power plants for generation of lower cost due to economy of scale

obtained in addition to serve the interests of contractors of major projects in Brasil, big

beneficiary of such works.

With respect to hydropower, its untapped potential in Brazil corresponds to 185.5 GW

of which 101.5 GW are located in northern Brazil, particularly in the Amazon region. It

was planned for the next twenty years, the installation in the Amazon region 60 large

hydroelectric plants with a generation potential of between 60 and 70 GW being the

main plants Belo Monte, Jirau, Santo Antonio, Estreito among others which represent a

great threat to many Amazonian indigenous peoples and the preservation of the Amazon

rainforest that plays a key role in combating global warming by acting as a carbon sink.

Although Brazil have a hydropower potential of 83 GW out of the North Region that

could be used without affecting the Amazon rainforest, the Brazilian government is

planning and implementing large hydroelectric projects in the Amazon region in

defiance of restrictions in terms of social and environmental. Another flagrant

irrationality in planning the electricity sector in Brazil lies in the fact that the Country

has a potential of 143.5 GW in wind power and plans to use only 3.3 GW in 2030

despite having a generation cost competitive with the hydroelectric plants. It should be

noted that wind farms can operate in complementation with the hydroelectric enabling

accumulate water in their reservoirs.

Great irrationality lies also in the fact that the PNE 2030 does not provide for the use of

large solar energy potential that exists in Brazil with the use of photovoltaic panels,

which should be widely disseminated in isolated communities in rural areas where the

cost of electricity supply Networking is higher and also thermo panels that should be

used for water heating in homes, hospitals, hotels, etc.. in cities. Also, was not properly

considered by the PNE 2030 the great potential of biomass that exists in Brazil, where

production of electricity from biomass is estimated to be around 10 TWh / year (10,000

GWh / year), to provide for the use of only 4,75 GW in 2030 corresponding to 2.1% of

power to be installed by 2030.

The PNE 2030 established the use of a power of 1.3 GW in power plants using

municipal waste which corresponds to 0.6% of the total capacity planned for 2030,

which is very little because Brazil produces 195,000 tonnes of waste urban solid

(garbage) per day that would be totally recovered enough to supply 30% of electricity

demand in Brazil today. Unfortunately, the PNE 2030 provides a capacity of 8 GW in

nuclear power in 2030, going against the global trend of banning the use of nuclear

power especially after the Fukushima accident in Japan. Besides, it will also be installed

irrationally 2 units on the banks of the São Francisco River attempting against the logic

that would indicate its best location close to the markets to be supplied.

2.2- Petroleum and natural gas sector in Brazil

In 1997, the petroleum investment law was approved with the liberalization of its

production and establishing a legal framework to regulate the petroleum industry. The

main objectives of the law was the creation of CNPE and ANP, increased use of natural

gas, increased competition in the energy market, and investments in power generation.

The state monopoly of petroleum and gas is over and energy subsidies were reduced.

However, the government maintained control of the complex monopoly power, in

addition to managing the price of certain energy products. Brazil is the 15th largest

petroleum producer in the world. Until 1997, Petrobras exercised a monopoly on

exploration, refining and transportation of petroleum in Brazil. With the end of the

monopoly, many private petroleum companies are involved in oil exploration.

Petrobras is a major world petroleum producer with production of over 2 million barrels

of oil equivalent per day. It is also a major distributor of petroleum products that has oil

refineries and oil tankers. In 2006, Brazil had 11.2 billion barrels and the second largest

proven petroleum reserves in South America after Venezuela. The vast majority of

proven reserves are located in the Campos and Santos basins, offshore southeastern

Brazil. In November 2007, Petrobras announced the discovery of petroleum in pre-salt

layer that believes it has between 5 and 8 billion barrels of recoverable light oil and

neighboring fields can contain up further, which could result in Brazil, becoming one of

the largest petroleum producers in the world. In late 2005, proved reserves of natural

gas in Brazil were 306 billion m3 and reserves as possible, should be 15 times larger.

Until recently, natural gas was produced as a by-product of the petroleum industry. The

main use reserves are located in the Campos and Santos basins. Petrobras controls more

than 90 percent of natural gas reserves in Brazil. Inside Brazil's pipeline systems are

operated by Transpetro, a subsidiary of Petrobras.

The National Energy Plan (PNE 2030) prepared by the federal government shows in

Figure 3 the consumption of petroleum by sector in 2009 in which one realizes that

most petroleum was directed to the industrial and transport sectors, totaling 64% of the

total.

Any solution that contributes to reducing the consumption of oil should lead to the use

of substitutes for gasoline and diesel in the transport sector and for the fuel oil in

industry. Among the substitutes for gasoline and diesel in the transport sector may be

cited as ethanol and biodiesel in the short term and hydrogen in the medium term. The

fuel oil substitute most appropriate in the industry and LPG in homes and services

would be natural gas because it is the cleanest fossil source of fossil fuels.

It is very large the potential for production of ethanol and biodiesel in Brazil. Many

analysts question the production of ethanol and biodiesel arguing that can compromise

food production. In Brazil, there would be no conflict between energy production and

food production provided there is an agricultural and energy policy interconnected.

Effort should also be made towards using hydrogen which presents itself as the energy

source of the future.

natural gas in Brazil in 2005 and 2030.

and should reach 201 million m3 in 2030 (4.5 times that of 2005 and 2.9 times that of

2010), according to the projection PNE 2030. The significant increase in production of

Page 11: A sustainable energy policy required to brazil

11

petroleum and natural gas in Brazil by 2030 will contribute to the greenhouse effect in

the atmosphere with its catastrophic consequences for the environment of the planet.

To help to prevent catastrophic climate change on our planet, urge the adoption of

policies aimed at implementing programs that contribute to the reduction of production

and consumption of oil and natural gas, as well as its substitution by other energy

resources. In this sense, we need to make: 1) substitution of petroleum products by

renewable energy (ethanol, biodiesel and biomass); 2) energy savings in the use of

petroleum and natural gas; 3) production of petroleum and natural gas mainly for non-

energy purposes as industrial raw material; and, 4) abandonment of investment in

petroleum and natural gas production in pre-salt layer.

2.3- The energy matrix of Brazil

2030 presented at the PNE 2030. Compared with the year 2009, there will be in 2030 a

drop in the share of petroleum and oil products, hydraulics and electricity sources and

firewood and charcoal and increase of natural gas, mineral coal and uranium.

progress in Brazil in the use of renewable energy with the PNE 2030 despite its

immense potential.

The slight decrease in the emission of CO2 in the atmosphere is insufficient to Brazil

contribute to combat global warming. A great irrationality of Brazilian government is

related to the decision to invest U.S.$ 174.4 billion in petroleum exploration in the pre-

salt layer in the next five years going against the fight global warming. To help to prevent

catastrophic climate change on our planet, urge the adoption of policies aimed at implementing

programs that contribute to the reduction of production and consumption of oil and natural gas,

as well as its substitution by other energy resources.

3. ENERGY POLICY REQUIRED TO BRAZIL

3.1- Policy required for the electric sector

Greenpeace has developed three scenarios for the electric sector in Brazil for the year

2050. The first is the Reference Scenario 2050, based on the study "Electricity Market

2006-2015" prepared by the Energy Research Company (EPE), linked to the Ministry of

Mines and Energy (MME). The second is the Intermediate Scenario 2050, prepared by

GEPEA (Group of Energy of the Department of Engineering of Energy and Electrical

Automation from USP-Universidade de São Paulo) in partnership with Greenpeace.

And the third is the Energy Revolution Scenario 2050, prepared by Greenpeace. In the

production of all scenarios, the GEPEA / USP was responsible for implementing the

modeling and the technical supervision of the work.

Page 14: A sustainable energy policy required to brazil

14

In Intermediate Scenario 2050 and the Energy Revolution Scenario 2050, the generation

of electricity from different technologies for electricity production is complemented by

efforts in the conservation and rational use of energy (energy efficiency). The five key

principles that guided the Energy Revolution Scenario proposed by Greenpeace are: 1)

Implement renewable solutions, especially through decentralized energy systems, 2)

Respect the natural limits of the environment, 3) Gradually eliminate the unsustainable

energy sources; 4) Promoting equity in resource use and, 5) Unlink economic growth in

the consumption of fossil fuels.

According to Greenpeace, greatly enhance energy efficiency is a crucial prerequisite to

meet the demand from a renewable energy matrix essentially. In the Energy Revolution

Scenario 2050, final electricity consumption reached 1009 TWh / year in 2050, or about

38% less than the consumption of Reference Scenario 2050. Energy efficiency measures

have the potential to reduce consumption at 413 TWh / year, deferring the need to

increase the generation of electricity during the period of analysis. This progressive

reduction in consumption should be achieved through the use of efficient electrical

equipment in all sectors. Other measures, such as awareness of society to conserve

electricity and management of electricity demand to shift peak usage intense, are

essential to achieve this reduction.

The Electric Sector Scenario 2005

According to the Ministry of Mines and Energy (MME), Brazil produced 367 TWh /

year of electricity in 2005. Renewable energy participated with 88% of total electricity

generation In 2005. The national electricity matrix in 2005 was composed as follows:

Total generation: 367 TWh / year

The Electric Sector Reference Scenario 2050

Energy source % Hydropower 84 Natural gas 4 Biomass and waste 4 Wind 0 Nuclear 3 Diesel and fuel oil 4 Coal 1 Photovoltaic panels 0 Total 100

Page 15: A sustainable energy policy required to brazil

15

In the Reference Scenario 2050, final consumption of electricity, which was 367 TWh /

year in 2005, reached 1639 TWh / year in 2050, an increase of 4.5 times in 45 years. In

the Reference Scenario 2050, there would be no progress in the share of renewable

energy in total electricity generation that would reduce from 88% in 2005 to 57% in

2050 and the contribution of energy efficiency would be negligible. In 2050, the

national electricity matrix will be composed as follows:

Total generation: 1639 TWh / year; Energy Efficiency: 0 TWh / year

Energy source % Hydropower 38 Natural gas 34 Biomass and waste 15 Wind 4 Nuclear 6 Diesel and fuel oil 3 Coal 0 Photovoltaic panels 0 Total 100

The Electric Sector Intermediate Scenario 2050

In the Intermediate Scenario 2050, GEPEA / USP considered energy savings through

energy efficiency measures, of 413 TWh / year, with a total generation of electricity

much smaller (1160 TWh / year) compared to 1639 TWh / year specified in the

Reference Scenario 2050. On the way proposed by GEPEA / USP, was reduced

electricity generation using fuel oil and diesel and considered a gradual reduction in

nuclear generation from 2030. The share of renewable energy in the Brazilian energy

matrix would reach 72% which is lower than that recorded in 2005 (88%).

Total generation: 1160 TWh / year; Energy efficiency: 413 TWh / year

Page 16: A sustainable energy policy required to brazil

16

The Electric Sector Energy Revolution Scenario 2050

In the Energy Revolution Scenario 2050, 88% of the electricity produced in Brazil

would be from renewable sources of energy, equivalent to its share in 2005 (88%). The

generation of 1077 TWh / year would be expected and there would be an energy savings

of 413 TWh / year through energy efficiency measures. The Energy Revolution package

excludes the generation of electricity from fuel oil, diesel, coal and nuclear.

Total generation: 1077 TWh / year; Energy efficiency: 413 TWh / year

Energy source % Hydropower 38 Natural gas 12 Biomass and waste 26 Wind 20 Nuclear 0 Diesel and fuel oil 0 Coal 0 Photovoltaic panels 4 Total 100

The Energy Revolution Scenario 2050 for the electric sector in Brazil proves to be

possible to pursue the dream of clean energy growth, supported by renewable energy

sources. The national electrical grid can become 88% renewable by 2050. Furthermore,

this array would help consolidate Brazil's commitment to cut by 2020 from 36% to 39%

the emissions of greenhouse gases, with the added benefit of promoting the economy

billions of dollars.

The challenge of reducing emission levels of greenhouse gases, allowing economic

growth and serve about 1 million people without power in the Country requires the use

of clean and sustainable sources of energy such as wind, biomass, solar photovoltaic,

solar thermal and hydropower, among others. The future of Brazil and the planet

depends on the redirection of subsidies today intended for conventional sources and

polluting fossil fuels - which will be depleted in the future - to renewable sources. The

future requires an energy revolution as proposed by Greenpeace for the electric sector in

Brazil.

At the center of this revolution is a change in the way electricity is generated,

distributed and consumed. The application of solutions towards a cleaner future goes

through decentralized systems, gradual elimination of unsustainable energy sources and

Page 17: A sustainable energy policy required to brazil

17

promoting equity in the use of natural and energy resources, unlinking economic growth

from increased consumption of fossil fuels.

The Brazilian electric system that presents nowadays many weaknesses in their

planning to set or choose projects to be implemented, many of them detrimental to the

environment, would be radically changed with the energy policies implemented on the

Energy Revolution Scenario 2050. In this scenario, would be abandoned current energy

policies that provide for the deployment of large hydroelectric dams in the Amazon

Region that will produce serious environmental impacts on the Amazon forest and

indigenous peoples, the deployment of nuclear power plants subject to risks of accidents

and problems of end disposal of nuclear waste and the deployment of conventional

power plants based on fossil fuels (coal and natural gas) generators of CO2 emissions

into the atmosphere.

The policy of supplying electric power required for Brazil should consider the

following:

Deploy SHP (small hydro power) or medium-sized hydropower and wind

turbines in several regions of Brazil rather than large hydropower for electricity

supply in Brazil, as has been the practice of the federal government's for many

years.

Deploy wind farms and hybrid systems in locations most appropriate.

Implement systems for solar photovoltaic or thermo where they justify.

Produce energy using biogas from landfills.

Produce energy in small and medium-scale and distributed in markets near the

sources of production instead of concentrated production of electricity by large

hydroelectric dams located far from markets energy consumers.

Produce energy with conventional power plants using natural gas that is the

cleanest fossil source.

Produce electricity with conventional power plants using natural gas (the

cleanest fossil source), wind turbines and solar photovoltaic or thermo systems

where justify their deployment to complement the hydroelectric generation.

Produce energy in the medium and long term with the use of hydrogen.

Abandoning nuclear power as an alternative energy to be costly and present

safety problems.

Page 18: A sustainable energy policy required to brazil

Save energy in all sectors of activity of Brasil.

Deploy cogeneration system in the industry to produce steam and electricity

using waste industrial production and natural gas.

Increase reliability in the operation of the electric system to minimize the effects

of blackouts using duplicate protection systems at critical supplies, duplication

of major trunk lines of transmission and use of wind turbines close to the power

grid.

3.2- Policy required for the petroleum and natural gas sector

Any solution that contributes to reducing the consumption of oil requires the use of

substitutes for gasoline and diesel in the transport sector and for the fuel oil in the

industry. Among the substitutes for gasoline and diesel in the transport sector may be

cited as ethanol and biodiesel in the short term and hydrogen in medium term. The

replacement of fuel oil would be more appropriate by natural gas in the industry because

is the cleanest source of fossil fuels.

To help to prevent catastrophic climate change on our planet, it is urgent to reduce

petroleum products consumption by adopting policies aimed at implementing programs

that contribute to their replacement by other energy resources. In this sense, we need to

make: 1) replacement of gasoline by ethanol and diesel with biodiesel in the short term

in the transport sector, 2) replacement of gasoline and diesel by hydrogen in the medium

and long term in the transport sector; 3) substitution of fuel oil by natural gas and

biomass in the industry, 4) replacement of coal by natural gas in the industry; 5)

substituting diesel by biomass and natural gas in the energy sector, and, 6) replacement

of LPG by natural gas in households and services sector.

Additionally, it is essential to adopt energy policies in Brazil aimed at implementing

programs that contribute to the reduction of petroleum consumption through energy

saving actions. These policies are as follows: 1) to produce steam and electricity in

industry with the use of cogeneration systems, 2) to encourage automakers and trucks in

order to raise the efficiency of motor vehicles to save energy, 3) to expand the railway

systems and waterways for freight transport instead of trucks, 4) to increase the public

transportation system, especially the mass transport of high capacity as the subway or

LRT (light rail vehicles) to reduce the use of cars in cities; 5) to restrict the use of cars

in town centers and other areas of the cities; 6) to encourage the manufacture to increase

19

machinery and equipment efficiency to save energy, and, 7) to use petroleum to non-

energy purposes, mainly as industrial raw material.

4. CONCLUSIONS

Taking into account the above, it can be said that sustainable energy policies required

for Brazil should consider the following:

1) Put into practice actions that contribute to the viability of the Energy Revolution

Scenario 2050 proposed by Greenpeace for the electric sector.

2) Adopt energy planning in Brazil on a rational and systemic basis.

3) Ensure the participation of states and municipalities in Brazil's energy planning so

that the needs of regional and local development of the energy sector are considered.

4) Overcoming barriers to the penetration of renewable political, legal, financial, tax,

technology, information, education and training.

5) Create an appropriate legal framework to support the development of renewable

sources of energy in Brazil.

6) Provide funding to investors in renewable energy to eliminate their risk aversion

represented by the high cost of production, the market is not yet well established,

the technology was not widespread and the scale of production is reduced.

7) Promote the full or partial tax exemption for renewable energy.

8) Ensure access to transmission and distribution of electricity to small independent

producers.

9) Recognize the social and environmental costs when comparing conventional

technologies and renewable technologies.

10) Impose taxes on carbon emissions and other pollutants in the operation of energy

enterprises.

11) Overcome obstacles in research, development and demonstration centers in Brazil

reinforcing the existing R & D and creating new ones.

12) Prepare the industrial apparatus to support the goals set for renewable sources.

13) Educate the rulers and the population of non-energy benefits, such as increased

income or employment generation offered by local renewable energy.

14) Increase federal support for renewable energy programs.

15) Develop a solid legal, regulatory and institutional architecture in order to reduce

risks for investors and financiers of renewable energy.

16) Articulate retail banks, regional development banks and development agencies to

promote renewable energy.

17) Strengthen the role of ANEEL and ANP so that they act with effectiveness in the

development of the energy sector in Brazil.

Renewable energy could be more involved in the Brazilian energy and energy savings

would be greater if it were eliminated one of the main obstacles posed by Eletrobras and

electric utilities, as well as by Petrobras that impede the realization of an national

energy planning on a rational and systemic basis in which Brazil's interests are above

the goals of corporations as occurs today which favor the use of large hydroelectric

plants and petroleum products and not making efforts to use renewable energy and save

energy because, in the latter case , would reduce the revenue of companies in the energy

sector.
