Assurance of quality energy is the most important input for development. Though India is the fifth largest producer of electricity globally, it remains a power-deficit state. It is poorly endowed with traditional fuel resources such as hydrocarbons, but blessed reasonably with renewable energy sources. Every step in harnessing them will make India energy self-sufficient. An attempt is made in this article to illustrate the initiatives of Karnataka State Women’s University to reduce load on national grid.

An important way to address global food security is to make better use of the food already produced. Since at least one third of global food is wasted before consumption, there are enormous incentives to cut this waste and create a more sustainable food system. This paper focuses upon saving food loss at the supermarket level in the US and channeling this food stream in new and efficient ways to those in hunger.

Large amounts of methane (CH4) are known to be emitted from permafrost environments during the autumn freeze-in, but the specific soil conditions leading up to these bursts are unclear. Therefore, we used an ultrawide band ground-penetrating radar in Northeast Greenland in autumn 2009 to estimate the volumetric composition inside the soil through dielectric characterization from 200 to 3200 MHz. Our results suggest a compression of the gas reservoir during the phase transition of soil water, which is accompanied by a peak in surface CH4 emissions.

A remarkable feature of nanobubbles (<10–6 m in diameter) is their long lifetime in water. Supplying oxygen-nanobubbles (NBs) to continuously flooded paddy soil may retard the development of reductive conditions, thereby reducing the emission of methane (CH4), a potent greenhouse gas, and dissolution of arsenic, an environmental load. We tested this hypothesis by performing a pot experiment and measuring redox-related variables.

Methane from enteric fermentation in the ruminant digestive system is a major contributor to anthropogenic greenhouse gas emissions in the United States and worldwide. Methane is also a net loss of feed energy to the animal. This study was undertaken to investigate the effect of a methane inhibitor on enteric methane emissions from lactating dairy cows. The experiment demonstrated that, under industry-relevant conditions, the inhibitor persistently decreased by 30% enteric methane emissions, without negatively affecting animal productivity.
