RenewableEnergyWorld.com’s Most Popular Stories of 2013

As editors we delight in learning which of the stories that we wrote or commissioned were most popular with our readers. That’s why at the end of each calendar year, we pull reports that tell us which stories we posted got the most shares, the most views, the most comments, etc. We also look at which videos were watched the most. Often, we post articles that we know will be a big hit: like explanations of controversial solar legislation. But other times you surprise us, readers, by taking great interest in articles that we felt were solid but not necessarily ground-breaking.

Bio-energy Forest Plantations for the Southeastern United States

Bio-energy forest plantations will supplement woody biomass from other sources such as logging residues. In the southern U.S., projections are for an increase of up to 25 million “new” tons of woody biomass demand for bioenergy. To supply this woody biomass demand will require purpose grown plantations of various species including pine, eucalypts, sweetgum, hybrid poplar and cottonwood, amongst others. Forest plantation yields can be 8-15 green tons/acre/year on rotations of 5-12 years. Utilization of this renewable and sustainable biomass resource will be as feedstock “designed” for a large number of bio-energy applications.

Latin America Report: Solar's Auction Debut in Brazil

After being shut out of previous renewable energy auctions, and delaying its own auction by two weeks, the state government of Pernambuco held the nation's first solar energy auction on December 27, registering 122.82 MW of energy, six times the country's current entire solar energy output (20 MW). The auction involved 34 bidders proposing roughly 1 GW of capacity; at the end it was narrowed to six companies from Brazil, Italy, Germany, China and Spain. Average price of power finished trading at 228.63 Brazilian reais/MWh (just under U.S. $97), about 9 percent lower than the starting price of R 250.
