Alternative Energy, Fuels & Raw Materials NEW FUEL FOR TUNSTEAD CEMENT PLANT, UK Tarmac Buxton Lime and Cement plans will increase the substitution of fossil fuels in its Tunstead cement plant to around 50 per cent. The company proposes to achieve this by using Calfuel, a specially prepared blend of non-hazardous materials such as paper, cardboard, plastics, textiles and wood chips that cannot be recycled and mostly go to landfill. Similar fuels are used successfully in power generation and cement manufacture in both the UK and elsewhere in Europe. Tarmac Buxton Lime and Cement plans to replace some of its coal with Calfuel and is submitting an environmental permit application to the Environment Agency so it can carry out a trial later this year. Alternative fuels such as tyre chips, and meat and bone meal are already being used in the cement kiln and have resulted in a reduction of more than 30% in the use of traditional fossil fuels since 2006. Using Calfuel will also help to keep Tunstead competitive in the high challenging cement market and help to secure hundreds of local jobs. Courtesy: World Cement, March 2010, P19. Renewable Energy BRAZIL, SOUTH AFRICA, INDIA, AND CHINA NEED MORE DETAILED RENEWABLE ENERGY POLICY -STUDY Brazil, South Africa, India and China - known as the 'Basic' country bloc - required more detailed policy measures to give investors confidence in terms of energy efficiency and clean energy, research by the Renewable Energy and Energy Efficiency Partnership (REEEP) has shown. The research, which was done as part of REEEP's Carbon Disclosure Project, was aimed at identifying corporate best practices in promoting energy efficiency measures and the use and development of renewable energy in the Basic countries. The researchers noted that all four these countries had framework legislation that set out principles and aspirations for greater energy efficiency and the use of renewable energy.

Wind WIND POWER CAPACITY India is the second largest wind power market in Asia, with a 14 per cent growth rate, reaching a total capacity of 11 GW in 2009. The onshore wind energy potential in India has been estimated at about 48 500 MW, assuming 1% land availability in potential areas for setting up wind farms @ 12 ha/MW in sites having wind power density greater than 200 Figure1 .
