The paper 'Challenges and Approaches to Electricity Grids Operations and Planning with Increased Amounts of Variable Renewable Generation: Emerging Lessons from Selected Operational Experiences and Desktop Studies' focuses on analyzing the impacts of variable renewable energy on the operation...

Many countries are scaling up their investments in renewable energy. In 2010, electricity production from renewable sources - wind, solar, biomass, biofuels, geothermal, hydropower, and ocean energy accounted for 18 percent of global electricity supply. By early 2011, renewables made up a...

Brazil has one of the world's cleanest energy portfolios, with 85.3 percent of overall energy production coming from renewable sources (compared with the worldwide average of 16 percent), and with 75 percent of the country's 105,000 megawatt (MW) installed generation capacity coming from...

Mexico's 2010 national energy strategy aims to promote sustainability and simultaneously increase energy access by increasing the share of renewable resources used to generate energy. The wind farms of La Ventosa, a windy area in the southeastern state of Oaxaca, are a key part of that strategy,...

Evaluations of renewable fuel standards typically compute the reduction in global greenhouse gas emissions based on the amount of fossil fuel “displaced.” However they universally fail to provide any explanation of how displaced fuel stops the production of fossil fuel. In spite of this,...
