The 11th plan has set what industry considers a modest target of 10,000 mw capacity addition in five years. Everyone agrees that much more is possible. But for this to happen, big time, the business of wind must be into energy generation and not just encashing credits because of investment subsidies.

Nature's News team looks at how much carbon-free energy might ultimately be available

Renewable Energy Certificates (RECs) are a type of environmental commodity intended to provide an economic incentive tor electricity generation from renewable energy sources. If renewable energy such as wind or solar power is to be supported for global, environmental or a country's energy security objective, it does not matter where the solar or the wind plant is located.

Rajasthan is one of the states that is bestowed with good wind energy potential in the country. Of the 45,000 MW wind energy potential identified by the Ministry of New and Renewable Energy (MNRE) sources, 5,400 MW has been assessed for Rajasthan. An assessment by the Centre for Wind Energy Technology (C-WET), Chennai shows that Rajasthan has encouraging wind profile for harnessing wind power.

Tripura Renewable Energy Agency (TREA) has adopted an ambitious plan for producing low-cost electricity. As part of the plan, one solar hybrid project has been installed on top of the Vigyan Bhavan recently. The project that was established at a cost of Rs 5 lakh is unique in nature as it uses both wind and sunlight to generate power. The project has been producing two-kilo watt power each day by using wind as well as Sun, said Subhash Chowdhury, Director of TREA here on Tuesday.

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.

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.
