Modern gears are performing heavier work and carrying greater loads than ever before. Gear manufacturers are redesigning, modernising and using finer steels to produce precision gears that will give better performance. This has never been truer than in the wind industry and the gears designed specifically for use in wind turbines. Furthermore, there is an increasing demand from all industries for more power in smaller packages.{pagebreak}Gears are used to transmit this power, and the same squeeze is on the gearbox - so how is it therefore possible to increase the load capacity of gears? Lubricant manufacturers have helped in addressing this need by developing better gear oils to help carry these increased loads safely. Lubrication Engineers Inc., ‘The Lubrication Reliability SourceTM' continues with extensive research and testing programs, to develop higher performance gear lubricant..

Japanese consumer electronics giants Toshiba and Sharp are in talks on a possible tie-up in the solar power generation field, the companies admitted last week. "It is true that we are holding talks on the solar cell business with other companies, including Toshiba," Sharp Corp. spokeswoman Miyuki Nakayama said, declining to give further details.{pagebreak}Sharp wants to enhance its solar business further, with its solar cell revenue expected to reach 170 billion yen (1.7 billion dollars) globally in the year to March 31, up 12 percent from last year, Nakayama said.Toshiba, which announced its full entry into solar power in January, said the company was also seeking a supply source of solar or photovoltaic cell panels that convert sunlight into electricity. "We are mulling where to procure panels as we do not make them

A bi-partisan gathering of legislators, business people, and environmental advocates were at the Texas State Capitol in Austin last week as State Senator Eddie Lucio, Jr. and State Representative Pete Gallego introduced legislation to allow the further development of the emerging renewable technologies market.{pagebreak}During this session, Texas legislators are looking at close to 100 bills filed on renewable energy, double the number filed during the last legislative session. 12 of the bills propose specific goals for increasing solar power, geothermal, renewable bio-mass, and small-scale wind.Lucio and Gallego filed identical bills that would raise the state's Renewable Portfolio Standard. The measures would increase electrical utilities' renewables generating capacity from resources other than "high capacity wind" to 4,000 megawatts by the year 2020."We have met our goals for wind and we are very fortunate in Texas to have massive clean energy resources besides wind," said Senator Lucio. "This legislative session, five different senators - Republicans and Democrats, urban and rural, and six different representatives - Republicans and Democrats, urban and rural agree.""We have all introduced legislation that would raise the Renewable Portfolio Standard requiring utilities to give Texans the clean energy they are asking for and industries are prepared to deliver -

The European Commission last week sent a reasoned opinion to Italy for failure to recognise certain guarantees of origin from other EU Member States. Under an EU Directive on electricity production from renewable energy sources,{pagebreak}Member States are required to establish a system of guarantees of origin and, as a general rule, to recognise those of other Member States. The Commission's reasoned opinion calls on Italy to take the necessary measures to comply with the Directive within two months.Several companies have complained that Italy refused to recognise guarantees of origin from France, Greece and Slovenia for renewable energy produced in 2005. Following investigation, the Commission has found that the refusal to recognise guarantees of origin from 2005 is unjustified. Therefore, Italy's action constitutes a breach of Article 5(4) of the Directive.Italy has a "green certificate" regime whereby electricity suppliers are obliged to hold "green certificates" (proof of the renewable provenance) for a certain share of their electricity. Suppliers importing electricity may be exempted from this obligation if they instead hold guarantees of origin (a European wide proof of the renewable provenance of electricity) from other Member States. In general terms, Italy recognises guarantees of origin, in accordance with the Directive, and

In the city of Moers near Duisburg, 120 project partners, customers and suppliers have inaugurated Germany 's largest photovoltaic plant using thin-film technology on a pitched roof.24 March 2009. The system provider Solaxis GmbH and Solardach GmbH have jointly developed a solar power plant on the roof of Riedel Recycling.{pagebreak}The solar modules have a total output of 837 kilowatts. The latest addition to the Riedel family - Jamain Riedel -symbolically flipped the switch, putting the solar power plant in operation, at the official inauguration on 21 March. Afterwards, some 120 visitors celebrated a spring festival to the music of the Ruhr River Jazz Band, drove a hydraulic platform 30 metres high to the solar modules and took a close look at the inverters. Among the participants were - in addition to the project partners, customers and suppliers -bank representatives and the mayor of the city of Moers , Norbert Ballhaus.The technical support came from the German subsidiary of the Swiss inverter manufacturer Sputnik Engineering.

The wind energy sector is attracting new sources of capital that compensate for banks' general reluctance to provide debt finance for projects, the European Wind Energy Association (EWEA) announced last week. A growing number of power companies with strong balance sheets are investing in wind energy and there is increasing interest from institutional investors, despite the financial crisis.{pagebreak}The sector expects to be among the first to emerge from the economic turmoil.However, governments and the European Investment Bank must urgently establish loan guarantees to ease the banking liquidity squeeze and accelerate economic recovery.The European wind energy market is less reliant on bank project finance than just three or four years ago as an increasing share of new installations are financed by institutional investors, infrastructure funds and from power company balance sheets."Whilst many sectors are struggling with falling demand for their products; the European wind power sector is not. Although the sector is doing well in attracting new sources of finance, EU governments should learn a lesson from the US recovery plan, which provides billions of dollars in loan guarantees to renewables. We need all channels of finance, including bank lending and export credits, to be wide open to meet demand," said
