Os custos da produção eléctrica com base em energias renováveis, financiada em regime especial, são afinal muito menores do que apontam as contas oficiais do sector, indica um estudo da consultora Rolland Berger para a Associação Portuguesa de Energias Renováveis (Apren), que será hoje apresentado em Lisboa. (...) As novas contas concluem que cada consumidor pagou, na factura eléctrica, uma média de 1,9 euros mensais para apoiar as energias renováveis em regime especial (regime que deixa de fora as grandes hídricas, ou barragens), entre 2005 e 2010 - um valor considerado aceitável pelos consumidores inquiridos pela Rolland Berger, abaixo dos 5,5 euros que são normalmente avançados. (...) Contas feitas, o estudo conclui ainda que a produção de origem renovável em regime especial teve um peso de 4% no custo total de geração de electricidade, entre 2005 e 2010, e não de 11% como tem sido avançado. E lembra as poupanças associadas à menor importação de combustíveis fósseis e de licenças de CO2, de 407 milhões de euros por ano.

JinkoSolar offers explanation, remediation for alleged toxic release at Haining PV cell factory
SolarServer
On September 15th - 17th, 2011 residents of Hongxiao, an adjacent village [to the Jinkosolar PV cell factory at Haining], gathered to protest the death of fish in a local waterway, with some protesters breaking into offices and destroying company property. On September 17th, 2011, JinkoSolar voluntarily closed the Haining plant.
Silicon wafer texturing and etching generate a fluoride solution as a by-product, which results in fluoride wastes. JinkoSolar (...) explained that a change in waste management contractors caused a delay in solid fluoride waste pickup, resulting in outdoor storage of waste. [D]ue to heavy rains in late August, fluoride waste "may" have leaked into a water channel near the factory.
JinkoSolar estimates that on September 5th, 2011, it became aware of the incident and commenced actions to clean up the affected area. The company isolated the water channel section and treated the affected water and soil, as well as constructing retaining walls, and building a water collection systems to prevent leakage. JinkoSolar has agreed to pay compensation for crop damage, as well as the death of any livestock or wildlife that may have been affected by the incident. It also notes that local environmental authorities are continually conducting water quality testing.
