Synergy with Hydropower Plants Boosts Biogas Production in Brazil

Fomenting biogas production among agricultural producers may seem at first glance to be a distraction from the purpose of Itaipu, the giant hydroelectric power plant shared by Brazil and Paraguay, but in fact it is part of their energy business strategy.

BIOGAS: Cow Dung Holds the Key to Nepal’s Green Economy

Nepal’s future may not be in hydropower, as most assume, but actually in the dung heap. A new industrial-scale biogas plant near Pokhara has proved that livestock and farm waste producing flammable methane gas can replace imported LPG and chemical fertiliser.

Solar and Biogas, the Perfect Agroenergy Duo in Brazil

"They're the ideal duo," because the combination of solar and biogas sources makes it possible to provide electricity around the clock, one during the day and the other at night, says Anelio Thomazzoni, a pig farmer who has become a producer of clean energy in southwestern Brazil.

Combining Biogas and Solar, the Best Energy Deal in Brazil

"Biogas is the best energy, it has no contraindications," and if you combine it with solar it becomes "the best energy business," at least in Brazil, says Anélio Thomazzoni.
