“…Brazil, for example, has a huge potential for the production of wind energy, (> 143 GW), solar energy, and a variety of alternatives for hydropower besides large dams (small hydroelectric plants-SHP, river hydrokinetic energy-RHK) [49][50][51][52] . Currently, Brazil would be losing approximately 20% of the energy due to defficien transmission 53. Using a conservative projection, improvements in the transmission and distribution system and repowering and modernizing existing hydropower plants could increase energy delivery of approximately 2.84% 54 .…”

SummaryMore than 100 hydropower dams have already been built in the Amazon basin and numerous proposals for further dam constructions are under consideration. The accumulated negative environmental effects of built and proposed dams, if constructed, will trigger massive hydrophysical and biotic disturbances that will impact the Amazon basin's floodplains, estuary, and sediment plume. By introducing a Dam Environmental Vulnerability Index (DEVI) we quantify the current and potential impacts of dams in the basin. The scale of foreseeable environmental degradation indicates the need for collective action among nations and states to avoid cumulative, far-field impacts. We suggest institutional innovations to assess and avoid the likely impoverishment of Amazon rivers.

“…Power supply portfolio scenarios for Brazil in a 2050 horizon have been developed in the Model for Energy Supply System Alternatives and their General Environmental Impact tailored to a Brazilian context (MESSAGE-Brazil), as described in Borba et al [2], Lucena et al [22], Malagueta et al [25], Nogueira et al [29] and Lima et al [21]. The MESSAGE-Brazil model is an integrated energy system model that estimates the least-cost expansion strategy for the Brazilian energy supply system to meet a certain exogenous demand, under specified constrains, namely energy resource availability, industrial installation capacity of each technology, investment costs, and political, social and environmental constraints.…”

a b s t r a c tThis work evaluates implications of incorporating LCA-GHG (life cycle assessment of GHG emissions) into the optimisation of the power generation mix of Brazil through 2050, under baseline and low-carbon scenarios. Furthermore, this work assesses the impacts of enacting a tax on LCA-GHG emissions as a strategy to mitigate climate change. To this end, a model that integrates regional life cycle data with optimised energy scenarios was developed using the MESSAGE-Brazil integrated model. Following a baseline trend, the power sector in Brazil would increasingly rely on conventional coal technologies. GHG emissions from the power sector in 2050 are expected to increase 15-fold. When enacting a tax on directcarbon emissions, advanced coal and onshore wind technologies become competitive. GHG emissions peak at 2025 and decrease afterwards, reaching an emission level 40% lower in 2050 than that of 2010. However, if impacts were evaluated through the entire life cycle of power supply systems, LCA-GHG emissions would be 50% higher in 2050 than in 2010. This is due to loads associated with the construction of plant infrastructures and extraction and processing of fossil fuel resources. Thus, taxes might not be as effective in tackling GHG emissions as shown by past studies, if they are only applied to direct emissions.

“…Donaji et al [3] used SAM to assess an annual production between the parabolic trough systems and power tower in Mexico and Spain. Malagueta et al [4] simulated four types of 100 MW CSP plants with parabolic troughs (simple plants, plants with hybridization and plants with thermal energy storage) based on the SAM at two sites: Bom Jesus da Lapa and Campo Grande. Purohit [5] had a techno-commercial feasibility of four types of CSP plants for 23 locations in India.…”

Concentrating solar power (CSP) plants only exploit direct beam solar radiation in order to generate electricity. It is generally assumed that CSP systems are economic only for locations with direct normal irradiation (DNI) above 1800 kWh/m 2 /year (about 5 kWh/m 2 /day). In the present study, talented regions of Iran to install CSP plants are identified by using the available measured data of global horizontal irradiation (GHI) from 21 cities. A computational code converts the measured GHI to DNI and by comparing the calculated data, six most talented city area of Iran are selected as the case study. By applying geographical, radiation and meteorological parameters to SAM software, the generation of electricity for a typical CSP plant for these locations are evaluated. The selected CSP plant is a parabolic trough (PT) power plant with capacity of 100 MW and 6 hour thermal storage. Results show that areas around the cities of Bandar-e Abbas, Bushehr, Esfahan, Kerman, Shiraz, and Yazd have more solar energy potential to establish CSP plants in Iran. Annual electricity power for these cities are calculated to be about 234 GWh, 245 GWh, 283 GWh, 318 GWh, 321 GWh and 318 GWh, respectively. Furthermore, employment of solar energy in these areas for electricity generation, considerably conserve fossil fuels and reduces CO 2 emission. Also, a comparison of DNI and power plant electricity generation in the 6 talented cities of Iran and 4 cities of Algeria are performed.
