SUSTAINABLE BUILDINGS FOR SUSTAINABLE FUTURE

The Institute of Rural Research and Development (IRRAD) is an initiative of S.M. Sehgal Foundation working on poverty reduction in rural villages in the State of Haryana, India. IRRAD's campus, which resides among some of the ultra-modern high rises of Gurgaon, meets the standards of the Leadership in Energy and Environmental Design (LEED) Green Building Rating System'. It generates 35Kw of solar energy on-site, enough for all the electricity requirements of the building except air-conditioning.

ALTERNATIVE ENERGY STORAGE

America's electric power grid is subject to immense inefficiencies that arise from the interplay between centralized power generation, local power consumption and on demand utility service.

COGENERATION FACILITY AT 102% EFFICIENCY

Remember the First law of thermodynamics? Energy can neither be created nor destroyed. It can only change forms. Or, if translated into an idiot-proof rule of thumb: you can't go above 100%. Remember this? Now forget it; this law has got a loophole.

DISTRIBUTED GENERATION - MICRO GRIDS

The term micro grid is mentioned more and more in publications on distributed generation. It generally means a collection of consumers, generators and potential energy storage entities connected together and operated as a small grid which is connected to the main grid, but capable of operating a self-sufficient island. The micro grid is typically linked to the grid with the help of a switch, which allows it to work both in grid-connected as well as island mode. However, island operation is not currently permitted in the majority of countries.

DRIVING THE HONDA CIVIC HYBRID

The electric motor gave the car a very smooth acceleration, with gear changes needed less often than I'm used to, and a very smooth delivery of power. The electric motor also seemed to smooth the gear changes so rather than the jerky transition you can get when accelerating and changing gear, it was altogether a more refined experience.

ECOFA - BIOFUEL MADE WITH GARBAGE

A group of Spanish developers working under the company name Ecofasa, headed by chief executive officer and inventor Francisco Angulo, has developed a biochemical process to turn urban solid waste into a fatty acid biodiesel feedstock.

HYDROGEN - BECAUSE WE NEED IT!

What follows is not meant to bash EVs, plug-ins or biofuels. And yes, hydrogen faces substantial challenges, chief among them vehicle cost and fueling infrastructure. But we need to be honest about all the options, or risk falling down the rabbit hole with Alice.
