Expansion of feedstock production for biofuels
Many Central American governments have declared biofuel production to be in their country’s national interest and have set aside land to grow sugarcane, African palm, jatropha, cassava, and other crops as biofuel feedstocks. However, land availability and suitability varies by region, and critics worry that feedstock expansion will encroach on communities, forests, and agricultural land.
Considering the importance of protecting forests, biodiversity, and food security, what are the most sustainable and promising biofuel feedstocks in Central America?

The Worldwatch Institute is a global leader in international renewable energy market and policy analysis. Each year, Worldwatch contributes to the REN21 Renewables Global Status Report, a leading reference publication that details worldwide renewable energy trends. Current projects include the production of comprehensive sustainable energy roadmaps for the governments of the Dominican Republic, Haiti, and Jamaica as well as a food and agriculture project titled Nourishing the Planet.
In this project, the Worldwatch Institute is collaborating with the INCAE Business School’s Latin American Center for Competitiveness and Sustainable Development (CLACDS) as a regional implementation partner. As INCAE’s principal research organization and ‘impact center’, CLACDS serves as an action-based think tank for the region’s governments, international organizations, private sector and civil society.

To my opinion the use of biofuels should be limited to processing of agricultural waste, because all first and second generation biofuels compete with food production and destroy rain forest: Food prices will rise and CO2 balance will detriorate as a result of diminishing forest CO2 absorption. Good examples is briquet production from sugar cane waste. This can in turn diminish deforestation: Currently roughly 50% of the energy demand in Nicaragua is still satisfied with firewood for cooking purpuses.
Another strong reason to limit the use of biofuels to waste processing is the extremely low efficiency with which solar radiation is converted to useful energy: approximately 0,5%. The land area involved is therefore huge. Photovoltaics perform roughly 30 times better in this respect, but exhibit the discontinuity problem caused by the lack of cheap and efficient energy storage.
A mi opinión el use de biocombustibles deberá ser limitada al uso de desechos agrícolas, porque los biocombustibles de primera y segunda generación compiten con la producción de alimentos y destruyen la selva tropical: Los precios de alimentos subirán y el balance de CO2 se empeorará porque la selva restante podrá absorber menos CO2. Un buen ejemplo es la producción de briquetas de desechos de caña de azúcar. Esta a su vez puede disminuir la deforestación: Al presente aproximadamente 50% de la demanda energética de Nicaragua está siendo satisfecha con leña para cocinar.
Otra fuerte razón de limitar el uso de biocombusitibles al procesamiento de desechos es le eficiencia extremadamente baja de conversión de radiación solar a energía utilizable: alrededor de 0,5%. La superficie necesaria será enorme. Los fotovoltáicos rinden aproximadamente 30 veces mejor al respecto, pero sufren del problema de la intermitencia causado por la falta de medios baratos y eficientes para el almacenamiento de energía.
