The common scientific armour against alternative energy systems, if we take the energy from water concept, for that matter, is the first law of thermodynamics (which leads to conservation of energy). It says "The increase in the internal energy of a system is equal to the amount of energy added by heating the system, minus the amount lost as a result of the work done by the system on its surroundings". In layman terms, it says energy cannot be created and input energy should be greater than output considering all systems are less than 100% efficient

Raktima Bose 3 more solar power plants for West Bengal Solar energy-run housing complex set up at New Town in Kolkata Aim is to achieve zero-carbon emission KOLKATA: West Bengal is pitching in in a big way to find alternative sources of power in the face of rising fuel cost and growing global warming. It is slated to get three more solar power plants in Purulia and Bankura districts, after the one at Asansol in Burdwan district, first of its kind in Southeast Asia, S.P. Gon Chaudhuri, Director, West Bengal Renewable Energy Development Authority (WBREDA), on Wednesday.

Hyderabad, July 13: With increasing power shortage, state government at last has started looking at non-conventional energy sources like solar and wind power to ease the burden on traditional power generation. From existing 2 MW capacity of wind mills, state government has finalised plans for 1000 MW in coming five years period.

Tanzania has one of the lowest rates of electrifi cation in the world. Zara Solar and its sister company Mona-Mwanza Electrical & Electronics both based in Mwanza provide high-quality, aff ordable PV systems in Northern Tanzania. Zara Solar is a rapidly growing business that uses a network of self-employed technicians to reach out to the remote rural areas.

A new revolutionary, renewable and clean energy product is showing the light, quite literally in many rural homes. The Kisan Torches and Lanterns manufactured by the Freeplay Energy Group and distributed by IFFCO (Indian Farmers Fertiliser Cooperative Ltd) need no batteries, no kerosene, no electricity and come with a very long shelf life including one year warranty.

The promotion of renewable energy is in line with India

Orlando Wagner and Jochen Hauff compare the booming renewables market with other sectors where a boom has been followed by a bust, on the lookout for danger signals. They conclude that the renewable energy sector has strong foundations - but does have some areas of vulnerability, which they examine in detail.

As would be expected in a maturing market, there are considerable changes in the wind energy industry, particularly when viewed over a period of several years rather than in any one year in particular. The size of wind farms continues to grow, as does the size of the wind turbines which populate them.

Biomass based power generation is one of the promising renewable options. This article reviews the status and potential of biomass based power for India.

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