Oil is cheap. Despite all the taxes that are placed in every single gallon of oil we buy, it is still cheap. But when we factor in both the human and environmental cost of oil, it is not cheap. The oil spill in the Gulf once again reminds us of the cost of our addiction to fossil fuels and the human and environmental cost involved in oil.

The World Bank expects Latin America’s power consumption to more than double between 2010 and 2030, and estimates that $430 billion of investment will be needed to meet that demand. An even more intimidating perspective comes from a recent World Energy Council report, which concludes that between now and 2050, “even in the best case, the growth of energy supply in [Latin America] will still be insufficient to meet the rising energy demand associated with economic growth.”

What’s causing these challenges for the region’s energy sector and the electricity industry in particular? Demographic, technical, and environmental factors are all compounding in ways not seen before.
To tee up our May 21st webinar conversation about energy efficiency potential in Latin America (which you can sign up for here), consider these three big challenges for Latin America’s electricity sector, and three big strategies for a successful future.
3 Big Challenges
1) A Rising Middle Class
The second decade of the 21st century signaled an historic shift in Latin American demographics: for the first time ever, more Latin Americans are living in the middle class than in poverty. And more are poised to join the ranks.
In Brazil, 37% of households will soon be middle-class or higher — up from 24% in the year 2000. This portends tens of millions new consumers moving into the middle class in Brazil alone between 2013 and 2爱上海同城交友论坛
What does a coral reef sound like? Perhaps surprisingly, it isn’t a cacophony of indie-band boings and wriggles.
In fact, thanks to University of Miami PhD candidate Erica Staaterman, you can hear a Florida coral reef in the video above, which documents her research into the behavior of pelagic fish larvae.
Billions of such “baby fish” are born every year, but must find their way to a coral reef to survive — a needle in a haystack journey, as Staaterman describes it. For her research at UM’s Rosenstiel School of Marine & Atmospheric Science, she set out to determine whether larval fish use the soundscape of the reef as a navigational tool.
The project, which in video form is a finalist in the National Science Foundation’s “Creating the Future” contest, involves playing the reef back to fish larvae in a special underwater chamber and then documenting their behavior.
