This paper focuses specifically on measures to increase the flexibility of power systems

After harsh contention the conservative and social democrats forming the fractious German government have agreed on a revision of the Renewable Energy Sources Act that regulates clean power promotion. Dispute was sharpest over provisions of photovoltaics.

The ability to know today how much wind power will be produced over the next few days provides a decisive advantage over the energy market. Thanks to a new system developed by German University spin-off energy & meteo systems, it's now possible to obtain an accurate forecast of the energy output from wind parks for up to ten days in advance.

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.
