Joint Fraunhofer ISE and NREL report hints at CPV maturation: pv-magazine 04. February 2015 | Applications & Installations, Global PV markets, Industry & Suppliers, Research & Development | By: Ian Clover Higher efficiencies and levelized costs of electricity at levels similar to ordinary PV reported as CPV sector set to grow in 2015. Although only a fraction of the global installed PV base, CPV could be on the cusp of cost and efficiency breakthroughs, the report finds. Isofoton A report by Germany’s Fraunhofer Institute for Solar Energy Systems ISE and the U.S. According to the report, Fraunhofer has achieved record efficiencies of 36.7% for CPV modules and 46% efficiencies for CPV cells in laboratory conditions, but the report also states that commercially available CPV modules regularly exceed 30% efficiency. At utility-scale, these CPV efficiencies could potentially reduce the amount of land required for a large solar plant, in turn allowing for a competitive LCOE as costs come down. Higher efficiency, but at what cost?
Challenges to connect small wind systems into grid in Brazil - Wiki Cleantech Summary The growing demand for energy – impelled by the social appeal for the use of sustainable energy, revitalizes the concept of distributed generation, characterized as that which is produced near the load. In this context, the use of small wind turbine connected to the grid plays more important role once they produce renewable energy and in a relatively simple manner when compared to other sources. 1. The search for a cleaner, renewable and sustainable electrical matrix allied to economic development of society has been object of discussions around the world. Large hydroelectric power plants support the Brazilian electrical matrix, while new projects based in wind farms, biomass and small hydroelectric power plants already arise on the national scenario . 2. 2.1 The sustainable development and the demand for energy The contribution of each energy sources in the electrical generation matrix in the years 2005 and 2010, together with the estimate for 2030 is presented in Figure 1.
US: solar could disrupt shale revolution, study finds: pv-magazine 09. February 2015 | Applications & Installations, Global PV markets, Industry & Suppliers | By: Ian Clover Report by energy research company Wood Mackenzie points to solar as the one technology with the capacity to transform energy markets in same way shale did. Cheaper, more efficient solar power will corner a greater share of the U.S. power market, but grid systems and storage backup technologies need to match the pace of change. Dennis Schroeder/NREL A report by international energy research company Wood Mackenzie has posited that solar PV has the capacity to disrupt the U.S. energy landscape with similar speed and tumult as the shale industry managed – and may even directly impact natural gas markets in the near future. Ghosh compares solar’s rapid rise to prominence to the upheaval caused by shale extraction technologies over the past decade, suggesting that the trend for cheaper solar modules will only continue as balance of systems (BoS) costs fall and efficiencies improve.
Improved access to public finance for solar may unlock the potential for distributed generation in Brazil | Apricum - The Cleantech Advisory Next to the utility segment, the commercial/residential rooftop segment of the Brazilian PV market offers good market potential, driven by very favorable conditions for self-consumption of generated power. Yet, the segment to date has not been able to reach significant scale. One of the main reasons for this is a lack of affordable funding. Apricum Project Manager Martin Mitscher examines Brazil’s solar financing challenges and advocates the role for public and private actors in developing suitable financing solutions, as successfully demonstrated abroad. Insignificant PV market development to date despite legislative backing After putting a strong focus on hydro and wind energy in past years, Brazil’s government has provided the legislative basis to incorporate solar energy in the country’s power generation mix. Already in 2012, the Brazilian government had passed a bill establishing net metering for small-scale renewable power. Net metering explained Solar irradiation Electricity tariffs

A methodology to identify the most strategic locations for large solar power plants using satellite images - Wiki Cleantech Summary The deserts are suitable areas for large solar power plants, because of abundant sunshine and enormous land. Both are important factors for solar power plants. However, not all desert areas are suitable for installation, for example sand dunes, water, and cliffs. Rich sunshine and huge land of deserts should have a possibility to generate huge amount of energy with solar power plants. Definition of suitable areas and land suitability index for solar power plants There are some types of deserts consisting different surfaces. However, there is some vegetation even in the gravel desert. Satellite images Images used in this study were taken by two satellites.

Big Corporations To Utilities: Please Make It Easy to Buy Renewable Energy This is an archived story. The information and any links may no longer be accurate. by Rona Fried We've written about the increasing amounts of renewable energy big corporations are using, but they would use much more if utilities made it easier for them to buy. A dozen companies signed the Renewable Energy Buyers' Principles, which ask utilities to do just that: Bloomberg, Facebook, General Motors, Hewlett-Packard, Intel, Johnson & Johnson, Mars, Novelis, Procter and Gamble, REI, Sprint, and Walmart. With a combined renewable energy target of 8.6 million megawatt-hours a year through 2020 (which would power nearly 800,000 homes a year), the companies are ready to make significant purchases. Currently, each company has to negotiate separately with utilities, to get the quantity of renewable energy they need at competitive prices. Microsoft bought the entire output of a wind farm going up in Illinois: Indeed, it's a reciprocal relationship. Here's what they want:
LatinAmerican Post - In Nationwide Protests, Angry Brazilians Call for Ouster of President Hundreds of thousands of protesters took to the streets in cities across Brazil on Sunday to express their ire at President Dilma Rousseff, raising pressure on her as she grapples with an onslaught of challenges including an economy mired in stagnation, a sweeping bribery scandal and a revolt by some of the most powerful figures in her governing coalition. The protests, organized to coincide with commemorations of the re-establishment of democracy 30 years ago after a long military dictatorship, reflect rising disenchantment with Ms. Rousseff after former executives at Petrobras, the national oil company, revealed an elaborate scheme in which they said they channeled huge bribes from contractors to Ms. The payoff racket coincided roughly with the period that Ms. Concerns are growing over a sluggish economy expected to contract this year as the boom of the previous decade recedes into memory. Pointing to rising polarization, some prominent supporters of Ms. Still, Ms.
