In Brazil a recent energy auction has shown that wind power is cheaper than natural gas in the country, and also a better investment opportunity. The competitiveness of sustainable energy sources continues to impress everyone (even with the subsidized resource-extraction industries), it’s only a matter of time until other sustainable energy options get this cheap.
They even expect the cost of wind power to decrease in the coming years!
EPE president and chief executive Mauricio Tolmasquim said the auctions show that wind and natural gas are competitive, predicting wind prices will continue to fall in Brazil.
“That wind power plants have been contracted at two digit prices, below 100 reals per MWh, showcases the energy market competition through auctions,” he said. “That wind power could reach these lows versus natural gas was unimaginable until recently.”
The energy auctions for a total of 92 projects were the first in Brazil for 2011, and also featured biomass, hydro-electric and natural gas projects.
Investments amounted to 11.2bn reals in total, for 3,962MW of energy that is slated to start generating in 2014.

The Federal Reserve Bank of Boston has done a study on the real cost of building a green home and they have busted the myth that building green is too costly. The bank has concluded that building green doesn’t break the bank, so to speak.
The intuitive view of most people might be that building green is going to be vastly more expensive and complex than building to the most basic standards required by local code. It follows that we assume affordable housing probably isn’t going to be green. But a recent article in the Communities and Banking magazine published by the Federal Reserve Bank of Boston (FSB) this spring busts the myth that affordable housing and green housing are opposite and mutually exclusive concepts.
The myth doesn’t hold up locally either. We’ve looked at a study of green housing and the energy savings it creates for residents of the Seattle Housing Authority. And in Portland the Housing Authority built its first HOPE VI project green as well. We’ve also looked at the study of housing and health where there is growing evidence that along with materials the location of housing can have an effect on resident’s health – and health care costs. And we’ve considered the savings that building green can create for schools and their communities.
