Cement, Energy and Environment

large number of cement companies have already drafted their own alternative fuel strategies (including Holcim, with its "Geocycle", for example). Lampe drew attention to the fact that modified technologies (such as the Polflam burner, or combustion chambers such as the Prepol staged reactor, for example) are necessary for the successful use of alternative fuels. He was followed by Dr. Thomas Marzi, of Fraunhofer UMSICHT (co– author: Manfred KOhl , of ThysenKrupp Xervon Energy GmbH), speaking on "Investigations of quality and aging behaviour of bottom ash". Grate ash must firstly be aged , in order to permit complete reaction of the content substances prior to further use as, for example, a substrate for highway engineering. Investigations may demonstrate that grate ash from alternative– fueled power generating plants reacts similarly to that from waste-incineration facilities.

GREEN ENERGY IN FOCUS WITH $2.3 TRILLION INVESTMENT PLAN ALTERNATIVE ENERGY SECTOR India will spend $2.3 trillion to boost its energy sector by 2030 by improving energy efficiency and using clean technology to help Asia's third largest economy balance growth and environmental aims. While the country will need to keep burning cheaper fossil fuel to expand the reach of electricity to half of its one-billion-plus population without power, relying on conventional energy alone would be unsustainable as reserves deplete and costs rise. Being the world's third-worst carbon emitter only makes it imperative to shift to a greener economy, Mr. B.K. Chaturvedi, a member of the Planning Commission, said. He said the country plans to spend $2.3 trillion on the energy sector by 2030, which will include a substantial burden for expanding the country's energy basket to include green sources such as solar, wind, and nuclear power.

Renewable Energy EURPOPE CHARTS PATHWAY TO 100% RENEWABLE ENERGY The world today is in need of a paradigm shift in energy production and usage to address the twin challenges of climate change and depleting fossil fuels and ensure a sustainable future. Recognizing the need to provide a framework for a sustainable future, the European Renewable Energy Council (EREC) - the umbrella organization of major European renewable energy industry, trade and research associations - recently prepared a report, 'RE– thinking 2050' which outlines a visionary pathway towards a 100 % renewable energy supply system for the European Union by 2050. Renewable electricity up to 2050 'RE-thinking 2050' estimates that in order to meet its 2020 climate and energy targets, approximately 330 GW of new power capacity needs to be built, which represents 42 per cent of the current EU capacity. The 'RE-thinking 2050' report calculates that with renewable electricity growing at an average annual rate of 14 per cent between 2007 and 2020, the EU will have an installed capacity of about 520 GW by 2020, thus achieving the power target quite easily. The report predicts the share of renewable electricity (RES-E) in the total final energy demand to increase from 10% in 2020 to 18 per cent in 2030 and finally 41 per cent by 2050. According to EREC, by 2020, all RES-E technologies will contribute to about 39 per cent of the total electricity consumption, and by 2030, the share will increase to about 65% - 67%, finally achieving 100% by 2050. By 2030, total RES-E installed capacity is expected to rise to 965.2 GW. This trend of a steep increase continues after 2030 leading to almost 2000 GW of installed capacity by 2050. Wind and solar photovoltaic (PV) are expected to lead both in terms of energy output and contribution to final energy. RES-E installed capacity of wind is expected to grow from 180 69
