"Climate News Roundup"
Trillions turn green – Market Watch. “Nearly 50 leading U.S. and European investors representing more than $8 trillion of assets met on Feb. 14 at the United Nations to lay out a timetable for their commitments to global climate change and to call on governments and other investors to act with their money as well.”
US Should Speed Up Energy Efficiency Plans – IEA – Reuters. “The US government needs to move more quickly on plans to boost automobile fuel efficiency standards, improve efficiency of power plants and take hard action on heat-trapping greenhouse gases, the International Energy Agency said Friday.”
Follow Germany’s lead, invest to save energy – The Telegraph (UK). An interesting spin on modernizing (and making efficient) the building sector (responsible for 39 percent of U.S. emissions – except this is in Germany/UK).
Easing concerns about pollution from manufacture of solar cells – Physorg.com
The study hasn’t been released, but it will be worth keeping an eye out:
Solar energy has been touted for years as a safer, cleaner alternative to burning fossil fuels to meet rising energy demands.
However, environmentalists and others are increasingly concerned about the potential negative impact of solar cell (photovoltaic) technology. Manufacture of photovoltaic cells requires potentially toxic metals such as lead, mercury and cadmium and produces carbon dioxide, which contributes to global warming.
In the new study, Vasilis M. Fthenakis and colleagues gathered air pollution emissions data from 13 solar cell manufacturers in Europe and the United States from 2004-2006. The solar cells include four major commercial types: multicrystalline silicon, monocrystalline silicon, ribbon silicon, and thin-film cadmium telluride.
The researchers found that producing electricity from solar cells reduces air pollutants by about 90 percent in comparison to using conventional fossil fuel technologies.
