...Your cover story provides a distorted, inaccurate picture of biofuels. The overwhelming body of data demonstrates the carbon benefits of biofuels. For every unit of energy it takes to make domestic biodiesel, 3.5 units are gained, giving biodiesel the highest energy balance of any liquid fuel. In 2007 alone, biodiesel's contribution to reducing greenhouse-gas emissions was the equivalent of removing 700,000 passenger vehicles from America's roadways. The U.S. biodiesel industry strongly opposes rain-forest destruction and nonsustainable agricultural practices. Biodiesel increases our renewable-energy supply, adds well-paying, green jobs to the economy and reduces carbons...
...Laboratory. TIME owes its readers the totality of facts to avoid misinformation. For many decades, the U.S. has worked with farmers and the scientific community to increase crop yields, reduce the intensity of pesticide and fertilizer use, improve water productivity and promote conservation tillage that reduces erosion and sequesters carbon. Last year alone our agencies invested more than $1 billion in research, development and demonstration of next-generation-biofuels production from nonfood feedstocks, which remains the core U.S. strategy. Our government is committed to advancing technological solutions to promote and increase the use of clean, secure, abundant, affordable and domestic...
...does. First, suggestions that Brazil is a major culprit in global warming are not supported by scientific facts or reliable statistics. Second, the growth rate of Brazilian emissions has been on the decline primarily because of decreasing rates of Amazon rain-forest deforestation, which is the main source of carbon emissions in Brazil, and increasing use of ethanol fuel. Furthermore, from 1970 to 2005 the use of ethanol in our energy mix has averted the emission of 644 million tons of CO2, the equivalent of Canada's annual emissions. When compared with the unsustainable energy patterns used in major developed...
...There are at present a number of viable alternatives that inhibit our breakneck carbon-emissions trajectory and have a potential to make a serious dent on the worldwide release of greenhouse gases. Among these are ethanol derived from sugar cane, which already drives approximately 85 percent of Brazil’s cars, and soy-derived biodiesel, which helps power all the diesel-burning trucks on our campus, according to David E. Harris, Jr., the general manager of operations and finance for Harvard University Transportation Services...
...National Geographic, soy-based biodiesel such as is used in Harvard’s fleet, contains 2.5 units of usable energy for every unit of energy used in its production (which compares favorably to corn ethanol’s ratio of 1.3:1), and decreases the emissions of carbon dioxide by 68 percent compared to standard diesel...
