Renewable energy
Renewable energy
Renewable energy is energy which comes from natural resources such as sunlight, wind, rain, tides, and geothermal heat, which are renewable . About 16% of global final energy consumption comes from renewables, with 10% coming from traditional biomass, which is mainly used for heating, and 3.4% from...

-only energy auction in 2009, in a move to diversify its energy portfolio. Foreign companies scrambled to take part. Early this decade, a drought in Brazil that cut water to the country's hydroelectric dams prompted severe energy shortages. The crisis, which ravaged the country's economy and led to electricity rationing, underscored Brazil's pressing need to diversify away from water power. The bidding is expected to lead to the construction of two gigawatts of wind production with an investment of about US$ 6 billion of over the next two years. Brazil counts on hydroelectricity

 in 1992. Ten years later the government created the Program for Incentive of Alternative Electric Energy Sources (Proinfa) to encourage the use of other renewable sources, such as wind power, biomass, and Small Hydroelectric Power Stations (PCHs). Such stations use hydropower, the flagship of Brazil's energy matrix, which comprises around three-quarters of Brazil's installed energy capacity.

High energy production costs, coupled with the advantages of wind power as a renewable, widely available energy source, have led several countries to establish regulatory incentives and direct financial investments to stimulate wind power generation.

Growth of wind energy

Since the inception of Proinfa, Brazil's wind energy production has escalated from 22 MW in 2003 to 602 MW in 2009, as part of 36 private projects. Another 10 projects are under construction, with a capacity of 256.4 MW, and 45 additional projects have been approved be ANEEL with an estimated potential of 2,139.7 MW.

Developing these wind power sources in Brazil is helping the country to meet its strategic objectives of enhancing energy security

 could potentially flood. Construction of the dam started in 1975, and the first generator was opened in 1983. Today, the dam provides over 75% of Paraguay's electric power needs, and meets nearly 25% of Brazil's electricity demands. It is estimated that 10,000 locals were displaced by the construction of the dam, and around 40,000 people were hired to help with the construction of the project. Many environmental concerns were overlooked when constructing the dam because the dam would produce such a large amount of energy with carbon free emissions, and no unwanted byproducts, such as with nuclear energy

Hydroelectricity

Hydroelectric power plants produce over 90% of the electrical energy consumed in Brazil. They depend on river waters in adequate levels in their ponds to generate energy. Lack of rainfall, investments and increased consumption resulted in electrical energy rationalization, known as black out, in the years 2001 and 2002. The construction of new hydroelectric power plants means environmental impacts as large areas need to be flooded, altering the ecosystem

Trying not to use too much energy during peak hours, between 6 and 9 PM, is necessary to avoid the need to build new energy plants and transmission lines only to serve the demand in that timeframe. New dams mean very elevated social and environmental costs due to flooding land tracts and destroying habitats of animals, plants and entire communities that, many times, are not compensated (resettlement or indemnities).

Brazil is the second largest producer of ethanol in the world and is the largest exporter of the fuel. In 2008, Brazil produced 454,000 bbl/d of ethanol, up from 365,000 in 2007. All gasoline in Brazil contains ethanol, with blending levels varying from 20-25%. Over half of all cars in the country are of the flex-fuel variety, meaning that they can run on 100 percent ethanol or an ethanol-gasoline mixture.

. Locally, plantations can lessen soil erosion, provide a means to restore degraded lands, offset emissions and local impacts from fossil-fired power generation, and, perhaps, reduce demands on existing forests. In addition to the direct power and environmental benefits, biomass energy systems offer numerous other benefits, especially for developing countries, such as Brazil. Some of these benefits include the employment of underutilized labor and the production of co- and by-products, for example, fuelwood.

Nearly all of the experience with biomass for power generation is based on the use of waste

 grown wood is an emerging technology with considerable promise. However, actual commercial use of plantation-grown fuels for power generation is limited to a few isolated experiences. Wood from plantations is not an inexpensive energy feedstock, and as long as worldwide prices of coal, oil and gas are relatively low, the establishment of plantations dedicated to supplying electric power or other higher forms of energy will occur only where financial subsidies or incentives exist or where other sources of energy are not available.

Brazil used tax incentives beginning in the mid-1960s to initiate a reforestation program to provide for industrial wood energy and wood product needs. As a consequence of the Brazilian Forestry Code with its favourable tax incentives, the planted forest area in Brazil increased from 470,000 ha to 6.5 million ha by 1993. With the discontinuation of the tax incentives in 1988, plantation establishment in Brazil has slowed although the commercial feasibility of using eucalyptus
