The grass is half-full : new biofuels from field to wheel
The current biofuels market in the United States is dominated by ethanol made from corn. But corn ethanol has limitations that will prevent it from displacing a large amount of fossil fuel use in the U.S. To achieve that goal, biofuels will need to come from different sources. Cellulose, one of the …

Do solar water heaters improve access to hot water and reduce electricity costs? : the complexities of implementing energy poverty interventions in South African Townships : a case study of Nyanga Township
Solar energy is abundantly available in South Africa, but it is a highly under-utilised resource. One way of efficiently using the resource is solar water heating (swh), a natural process whereby hot water for domestic and/or industrial use is heated by the sun. In 2009, a national swh strategy was …
