Concerns for energy conservation, developing sustainable energy sources and interest towards national energy security benefits combined with growing environmental pollution is necessitating the search for renewable energy sources. Of the renewable energy sources, biomass is highly flexible and the least cost alternative.

The role envisioned for liquid biofuels for transport has come under increased scrutiny in the past year or two, due to the potential social and environmental impacts associated with scaling up biofuels production and use from its low level

Tapping of renewable energy resources of wind, solar and bio-fuels is necessary to resolve the prevailing energy crisis and reduce the growing trade deficit. Environment Protection Department Additional Secretary Dr Zafar Abdullah stated this while speaking at a seminar on 'Clean Energy for Safe Environment and Sustainable Development' here at a local hotel on Wednesday. EPD Director General Dr Shagufta Shahjehan chaired the seminar.

GREEN EARTH Sinivasa Raghotham Around the world, governments and power utilities, struggling against skyhigh oil prices and global warming, are turning to solar power as the next big source. Here are some of the largest projects under implementation or planned.

George Unzelman, has more than 50 years of refining experience and has been in the industry during some of its most dramatic changes-some predicted, some results of opposition. In an opinion editorial, Unzelman shares his observations and predictions moving forward.

This paper analyses the current status of rural renewable energy in China and India, develops and employs an analysis framework to study the environment, channels, instruments and innovative mechanisms of financing rural renewable energy in China and India, and makes a primary comparison.

A recent development in solar energy is a solar tower/chimney.It is a method used for large-scale generation of electricity from solar radiation.The principle is very simple.It is based on the well kn

Although wind energy is a rapidly growing technology its use remains geographically concentrated, with more than 75 percent
of global installed capacity found in just five countries. These countries, and others wishing to develop wind energy have

Electricity from renewable sources may be fairly cheap to make, but it cannot be stored and produced when needed. But the solar industry is moving to solve both problems with a single approach: gather heat from the sun, boil water into steam, spin a turbine and make power. Solar power, the holy grail of renewable energy, has always faced the problem of how to store the energy captured from the sun's rays so that demand for electricity can be met at night or whenever the sun is not shining.
