Santiago, Chile, 14/3/2013 – Três povoados indígenas do altiplano do Chile acabam de receber equipamentos de energia solar. As destinatárias são cinco moradoras que cruzaram o planeta e as barreiras idiomáticas para aprender na Índia técnicas fotovoltaicas que agora aplicam em suas aldeias. As atacamenhas Luisa e Liliana Terán, primas da comunidade Caspana, as quechuas Elena Achú e Elvira Urrelo, de Ollagüe, e a aymara Nicolasa Yufla, de Toconce, têm o desafio de instalar esses equipamentos e revelar seus mistérios aos habitantes dos três povoados, com pouco menos de mil pessoas.

Nessas localidades, a mais de três mil metros de altitude e quase no limite com a Bolívia, não há eletricidade e a água escasseia. “Temos luz por gerador apenas duas horas e meia por dia à noite”, contou à IPS por telefone a artesã em pintura rupestre Luisa Terán.

Cheap Oil to the Rescue, Economist Predicts

-Economist Robert Z. Aliber didn't hedge his prediction on what a barrel of oil will cost one year from today.

“It will be at $56.65,” he declared, down sharply from its current level of about $90.

Cheap???  This only promotes burning more fossil fuel which we already can't afford!

Comparing The Carbon Footprint Of Energy Storage Technologies

Comparing The Carbon Footprint Of Energy Storage Technologies | Sustain Our Earth | Scoop.it
Stanford scientists recently completed a very interesting and useful study on the carbon footprint of different types of energy storage.

 

When Barnhart crunched the numbers, the results were clear. “We determined that a pumped hydro facility has an ESOI (Energy Stored on Investment) value of 210,” he said. “That means it can store 210 times more energy over its lifetime than the amount of energy that was required to build it.

 

The five battery technologies fared much worse. Lithium-ion batteries were the best performers, with an ESOI value of 10.

 

The best way to reduce a battery’s long-term energetic costs, he said, would be to improve its cycle life – that is, increase the number of times the battery can charge and discharge energy over its lifetime. “Pumped hydro storage can achieve more than 25,000 cycles,” Barnhart said. “That means it can deliver clean energy on demand for 30 years or more. It would be fantastic if batteries could achieve the same cycle life.”

 

“The most effective way a storage technology can become less energy-intensive over time is to increase its cycle life,” Benson said. “Most battery research today focuses on improving the storage or power capacity. These qualities are very important for electric vehicles and portable electronics, but not for storing energy on the grid. Based on our ESOI calculations, grid-scale battery research should focus on extending cycle life by a factor of 3 to 10.”

As long as the energy cost to produce a storage device is less than the energy savings we can get out of using the storage, then it is net gain, but it still may not be competitive.
