This week in renewable energy: 8/30/13

Every Friday, Community Renewable Energy shares important clean energy developments– and some that are just plain cool.

Here’s what we were reading this week.

Bright ideas

On World Policy, Konrad Putzier provides a smart overview of solar power’s progress:

Since 1977, the price of photovoltaic cells, needed to produce solar power, has fallen from $ 76.67  per watt of installed capacity to forecast $ .74 in 2013, according to Bloomberg. This follows the so-called Swanson’s Law, which states that the cost of producing such cells falls by 20 percent every time production capacity doubles, thanks to both technological advances and economies of scale. With no signs for a slow-down in global demand for solar power, this trend looks likely to continue.

  • India continues to embrace solar power. (Hindu Business Line)
  • PV Magazine describes how Brazil is looking to add solar power capacity after embracing wind power:

The system of federal auctions, which single-handedly helped to develop Brazil’s booming wind energy market, is seen as the best shot for most solar developers in the country. Not surprisingly, Brazil’s Electricity Regulatory Agency (ANEEL) recently received half a dozen new requests for regulatory authorization to develop and operate photovoltaic plants totaling 160 MW of installed capacity in August alone.
