    Solar manufacturers are finding it difficult to eke out additional increases in how efficiently crystalline-silicon solar panels convert sunlight into electricity--so solar innovation has shifted to back-of-the-panel electronics. "Every incremental power advantage brings down cost per watt, and electronics are where the improvements are going to be," says Matthew Feinstein, a research associate at Lux Research. National Semiconductor's power-optimizing device is already on the market. Tests on customer installations have shown that it can squeeze 25 percent more energy from a photovoltaic system, says Kevin Kayser, a marketing manager at the company. Independent tests by the National Renewable Energy Laboratory and Photon International have demonstrated power gains from arrays as high as 39 percent.

    Germany, forces consumers to pay nearly four times the rate in the US to help subsidize its solar-power industry. Spain, tried to subsidize its solar industry but faltered in the face of a fiscal crisis. http://www.csmonitor.com/Commentary/the-monitors-view/2010/1019/The-cold-war-in-clean-energy

    In solar energy, it is the State which creates the market, but not the sunshine. Atleast as of now.

    The German electricity grid faces instability because of too much solar power, an expert said. Thanks to a generous feed-in tariff, the installation of rooftop solar panels and large-scale photovoltaic plants has exploded in Germany. Stephan Kohler, chairman of the DENA agency, an energy adviser to the government, has warned that the green boom could turn into a disaster for Germany's aging power grid.

    This article of Meenakshi Rohatagi is even more detailed than Mridul Chadha's in cleantechnica . Mridul is a student writer. Meenakshi Rohatgi is a correspondent at the Technology Review and this article gives the current status of all renewable energies in India. Atleast the most important ones. It is a very very good article and is a must read for all renewable energy ethusiasts in India. There are many loopholes that need to be plugged before India can be on the path to harvest alternative sources of energy or even utilize them to reach its set targets. There is a lack of knowledge about solar energy applications such as decentralized small scale solar power plants to substitute diesel gensets. Even the use of biodiesel with petroleum diesel, or ethanol with petrol, to reduce emissions has not gained widespread popularity because of the marginal profits as only two to three percent of biofuel is added in diesel. Government policies play a major role in financing renewable energy projects and to assure high returns. The government needs to collaborate liberally with domestic players to spread awareness about the use of renewable energy installations at the individual, community, and enterprise level.

    Oil Secretary S. Sundareshan today said that India will launch its first-ever offer of shale gas areas for exploration by the end of 2011. What is Shale? Oil shale, is an organic-rich rock contains significant amounts of kerogen (a solid mixture of organic chemical compounds) from which liquid hydrocarbons can be extracted. Kerogen requires more processing to use than crude oil, which increases its cost as a crude-oil substitute both financially and in terms of its environmental impact. India is known to hold shale gas resources in several basins including the Cambay (in Gujarat), Assam-Arakan (in the North-East) and Gondwana (in central India). Previously, shale gas deposits were not considered worth tapping, and it was only when Houston billionaire George P. Mitchell pioneered new extraction techniques in the 1990s, the trend changed. Oil Minister Murli Deora said that India is likely to sign an agreement with US Geological Survey during US President Obama's visit to the country. The MoU with the US will aim at identifying basins with good prospects and added that the policy on shale gas would be in place before end of 2011. USA, China have well-established oil shale industries, and Brazil, Germany, Israel and Russia also utilize oil shale. Extraction of shale gas needs a lot of water and high hydraulic pressure;studies must be made on the the effects shale gas drilling has on water quality, aquifers and watersheds. Carbon di oxide emissions are higher than in conventional oil production. Before launching into shale extraction , I feel its imperative for the environmental impact to be looked into.

    I found this site giving an overall picture of the energy scene in India 2020-2030; govt plans, policies, trade incentives, and various future schemes to promote renewable energy India's planners have clean energy sources like solar, wind and hydro power in focus as the foundations of the new green economy. India’s $2.3 trillion energy investment plan over the next two decades is aimed at Renewable energy and energy efficiency . Solar Energy India’s National Solar Mission is already underway. India plans to install 20,000 MW of solar PV and solar thermal power plants across the country by 2022. The government is also planning to promote small-scale solar power systems for commercial buildings and homes. Wind Energy Wind energy is the centerpiece of India’s renewable energy infrastructure. Although confined mainly to the coastal states, it makes up 70 percent of the installed clean energy generation capacity. It has been estimated that wind energy could meet almost 24 percent of India’s electricity demand by 2030.. However, India is yet to estimate the offshore wind energy resource which could far exceed the onshore resources. Hydro Power India is also planning to build several large and small-scale hydro electric power plants. While the large-scale plants are bound to face opposition on grounds of environmental degradation and eviction of human population, the small scale projects could prove to a real boon for the energy-starved country. Energy efficiency India has launched a national plan for improving energy efficiency. The Bureau of Energy Efficiency (BEE) is the nodal agency for planning energy efficiency projects. It also has the responsibility of providing energy By Q2 2011, BEE plans to launch the Energy Efficiency Certificate trading scheme. The agency has identify over 700 industrial sectors which will be assigned energy efficiency targets which they would have comply with.The industries which fail to achieve their targets can buy the energy efficiency certificates…

    Though India receives the second highest solar radiation after California in the U.S., the solar equipment and solar energy market is not growing here, mainly owing to the high cost of the Silicon based solar cells used for generation of energy from solar PV.

    With 300 sunny days and average insolation at 1700 %u2013 1900 kilowatt-hour in most parts of the country totalling a mammoth 5,000 trillion kWh per annum, the case for widespread use of solar power in India is a no-brainer. K.Subramanya Tata BP solar

    For a country as deficient in electricity supply—with the per capita consumption of electricity at one-fourth the world average and roughly half the population literally living in darkness—and as richly endowed with sunshine, with 300 sunny days and average insolation at 1700 – 1900 kilowatt-hour in most parts of the country totalling a mammoth 5,000 trillion kWh per annum, the case for widespread use of solar power in India is a no-brainer. And yet, solar power has remained marginal even as wind energy has taken off (10,000 megawatt installed) for a host of reasons including perceived high cost of installations. However, solar is finally getting its place in the sun! K Subramanya, CEO Tata BP Solar Credit: Ajay Vishwanathan Concerns on energy security and availability as well as India’s commitment to combating global warming have prompted the government to launch the Jawaharlal Nehru National Solar Mission (JNNSM) which has set out an ambitious target of setting up 20,000 MW of grid connected solar power plants and another 2,000 MW of off-grid solar installations by 2022. Solar thermal or concentrated solar power (CSP) as a technology disappeared after its launch in the US in early 1980s and has reappeared in the last two years in Spain where currently some large scale CSP plants are under way. While photovoltaic cells and modules manufacturing has established itself in India, there is no CSP/ solar thermal industry in India and no CSP plants of any scale have been established yet. It is therefore a big technology risk that the government has taken by allocating 50 percent of the solar mission Phase 1 capacity of 1,000 MW for solar thermal projects. It would have been better for the government to first set up some technology demonstration projects on MW-scale and let the technology be validated in the Indian condi­tions before allocating capacity for it. Within solar photovoltaic, almost 90 percent of the global market is based on using crystalline silicon technology.…

    India’s wind energy potential has only been partially realised due to the lack of a coherent national renewable energy policy. The lack of a national policy is hampering genuine progress. Should the govt look at Wind Mission similar to the JNN SM? India’s rapidly growing economy and expanding population make it hungry for electric power. In spite of major capacity additions over recent decades, power supply struggles to keep up with demand. . Solar energy is likely to meet the shortfall to some extent. Wind energy could also supplement the hunger for power. It seems likely that the wind power potential is considerably underestimated. The Indian Wind Turbine Manufacturers Association (IWTMA) estimates that at hub heights of 55–65 metres, potential for wind development in India is around 65–70 GW. The World Institute for Sustainable Energy, India (WISE) considers that with larger wind turbines, greater land availability and expanded resource exploration, the potential could be as great as 100 GW. The possibility to register projects under the Clean Development Mechanism (CDM) provided a further incentive to wind energy development. By 1 September 2010, 416 Indian wind farm projects were in the CDM pipeline, accounting for 6,839 MW, second only to China. The ten years between 2020 and 2030 should see spectacular growth, more than doubling the installed capacity for wind power and taking it to over 160 GW.

    With about 250-300 clear sunny days in a year, India's solar power reception is about 5,000 trillion kilowatt hour per year, meaning just 1 percent of India's land area can meet the country's entire electricity requirements till 2030. Tata BP Solar, a joint venture between Tata Power (TTPW.BO) and BP plc's (BP.L) solar unit, BP Solar, and Bharat Heavy Electricals Ltd (BHEL.BO), Lanco Infratech BO) are all excited about this huge potential. Debashish Majumdar, chairman and managing director of Indian Renewable Energy Development Agency, told the Reuters Global Climate and Alternative Energy Summit that a strong investor interest in India's solar power indicated the goal of 20 gigawatts by 2022. could be met..

    PARIS - FRENCH construction materials group Saint-Gobain said on Monday it would build a solar panel plant in South Korea with Hyundai Heavy Industries, one of the country's biggest companies. The investment, for which no figure was given, will be made via an equally-owned joint venture, Hyundai Avancis, which will run a plant capable of turning out solar panels with an annual power rating of 100 Megawatts - enough to supply a town of 15,000 people. Saint-Gobain's Avancis unit operates a solar panel plant in Germany and is building another one there. The South Korean factory should come on line in second quarter 2012 and Saint-Gobain said in a joint statement that the investment significantly accelerates its solar energy programme. -- AFP

    Wind energy will increase to make up between five and 22 percent of world power generated by 2030 and countries must do more to expand electricity grids to cope, a study by pro-wind groups showed on Tuesday. Nations in Latin America and Africa were shifting to wind alongside established markets in Europe, North America, China and India 1 how will India benefit from this growing demand? 2 Will there be sprouting of new Suzlons? 3 Should the government come up with a Wind Mission similar to the solar mission?

    Suzlon Energy Ltd., India’s biggest wind-turbine manufacturer needs financing to enlarge its presence in the wind- energy markets of China and India to help offset slowing orders in Europe after the debt crisis made it difficult to raise funds for renewable-energy projects. Suzlon plans to raise as much as 50 billion rupees ($1.1 billion) by selling shares or debt to help fund expansion and repay loans.
