Al Jazeera: A dam-building boom across the developing world will bring electricity to growing, power-hungry cities across Asia, Africa and Latin America. But it can also put the worlds climate and people at risk, according to a new study by researchers aiming to reduce the host of environmental problems that can come with dam construction. Researchers at Tübingen University in Germany have have compiled a database of the 3,700 different dam projects planned or underway worldwide. They predict that global hydropower...

Grist: Up to one fifth of the world`s electricity supply could come from wind turbines by 2030, according to a new report released this week by Greenpeace and the Global Wind Energy Council (GWEC). That would be an increase of 530 percent compared to the end of last year. The report says the coming global boom in wind power will be driven largely by China`s rebounding wind energy market - and a continued trend of high levels of Chinese green energy investment -- as well as by steady growth in the United...

Yale Environment 360: Expanding electricity to the homes of 650 million people in India over the past 30 years had minimal direct impact on the countrys greenhouse gas emissions, according to a study published in Nature Climate Change. Although many humanitarian and development organizations have stressed the importance of improving electricity access in low-income countries, it has been unclear how this would impact overall emissions levels. An analysis of trends in India between 1981 and 2011 shows that expanding household...

Access to electricity in India has no impact on climate change

Economic Times: Improving household electricity access in India over the last 30 years contributed only marginally to the country's total carbon emissions growth during that time, according to a new study. While increased energy access is widely agreed to be an important goal for development efforts, such as the UN Sustainable Energy for All Initiative, the climate impacts of increased access to electricity have been unclear. The study is the first to examine the impact of electricity access on carbon dioxide...
