Alternative Clean Energy Roundup: 29 March 2013

Is The Sky The Limit For Wind Power?
March 27, 2013 - Wind power is growing faster than ever — almost half of the new sources of electricity added to the U.S. power grid last year were wind farms.

But is the sky the limit? Several scientists now say it's actually possible to have so many turbines that they start to lose power. They steal each other's wind.

Sailboat captains experience a similar phenomenon; they call it "dirty air." If you're sailing directly downwind of another sailboat, you'll slow down. That's because the lead boat creates a turbulent vortex of air behind it as the wind spills off its sails. As sailors know, "dirty air" means less power. read & listen to>>>

EU to Start Debate on Energy, Climate Rules Amid Crisis
Mar 27, 2013 - The European Union’s executive started a debate today on EU climate and energy rules as the crisis-ridden bloc seeks a long-term plan to cut greenhouse gases and promote clean power technologies.

While the 27-nation bloc is making “good progress” toward its 2020 goals to boost the share of renewable energy and cut greenhouse gases, a framework for the subsequent decade is needed to give investors legal certainty, spur innovation and prepare for a global climate deal, the European Commission said in a consultation paper published in Brussels. read more>>>

UK firm nets major contract from Chinese wind turbine producer
26 March 2013 - Oxfordshire-based vision system manufacturer, Meta Vision Systems, has received an order from a large Chinese windtower manufacturer for 14 of its DLS digital laser scanners. They will be used to automate welding operations during production of monopiles for offshore wind installations.

Meta’s DLS is unique among laser vision sensors for welding in that it uses the scanning spot principle rather than the more usual laser stripe method. The scanning spot system has significant advantages when welding the deep joints that are common when manufacturing monopoles, where wall thickness can be over 100 mm. read more>>>

Solarexpo/The Innovation Cloud to launch new project to foster global growth of renewables
26 March 2013 - Solarexpo/The Innovation Cloud will launch the "Internationalization Hot Spot," a new project for investment opportunities in emerging renewables at its inaugural conference, 8-10 May at the pavilions of the Fiera Milano-Rho in Milan.

The intent of the project is to provide marketing and business intelligence tools -- combined with a matchmaking service -- to promote investment opportunities for Italian operators in new emerging markets for renewable energies. read more>>>

South Africa: Brics Group to Promote Green Economy
28 March 2013 - The BRICS countries - Brazil, Russia, India, China and South Africa - have pledged to support one another in their collective fight against global warming and climate change.

Delegates attending the 5th BRICS summit in Durban on Wednesday signed a multilateral agreement on climate cooperation and the green economy, which will see the exchange of technical and financial support to address the impact of climate change on developing countries. read more>>>

Global warming predictions prove accurate
Analysis of climate change modelling for past 15 years reveal accurate forecasts of rising global temperatures

27 March 2013 - Forecasts of global temperature rises over the past 15 years have proved remarkably accurate, new analysis of scientists' modelling of climate change shows.

The debate around the accuracy of climate modelling and forecasting has been especially intense recently, due to suggestions that forecasts have exaggerated the warming observed so far – and therefore also the level warming that can be expected in the future. But the new research casts serious doubts on these claims, and should give a boost to confidence in scientific predictions of climate change. read more>>>
