Wind, solar power paired with storage could be cost-effective way to power grid
Renewable energy could fully power a large electric grid 99.9 percent of the time by 2030 at costs comparable to today’s electricity expenses, according to new research by the University of Delaware and Delaware Technical Community College.
A well-designed combination of wind power, solar power and storage in batteries and fuel cells would nearly always exceed electricity demands while keeping costs low, the scientists found. (more…)
A new assessment of wind energy in India by Lawrence Berkeley National Laboratory has found that the potential for on-shore wind energy deployment is far higher than the official estimates— about 20 times and up to 30 times greater than the current government estimate of 102 gigawatts. This landmark finding may have significant impact on India’s renewable energy strategy as it attempts to cope with a massive and chronic shortage of electricity.
“The main importance of this study, why it’s groundbreaking, is that wind is one of the most cost-effective and mature renewable energy sources commercially available in India, with an installed capacity of 15 GW and rising rapidly,” says Berkeley Lab scientist Amol Phadke, the lead author of the report. “The cost of wind power is now comparable to that from imported coal and natural gas-based plants, and wind can play a significant role in cost effectively addressing energy security and environmental concerns.” (more…)
Armonk, NY and Copenhagen, Denmark & COPENHAGEN, Denmark – 13 Oct 2011: IBM today announced it has joined a collaborative consortium to help develop an energy grid that uses at least 50 percent of renewable energy sources, such as wind power, solar energy and biogas. Led by a European Union-funded consortium, the EcoGrid EU project will demonstrate a smart energy grid that will allow smart devices to use renewable electricity based on near real-time pricing and availability.
The EcoGrid EU project will be piloted on the Danish island of Bornholm with 2,000 residents and commercial users, representing approximately every tenth house on the island. Using smart meters and a Web-based app, that runs on smartphones, tablets and PCs, consumers can schedule when to purchase electricity online and at what price. Project scientists believe that by making this data easily available, eco-conscious Danes will choose to purchase renewable energy over fossil fuels, which will result in cost savings. The portal will also enable utilities to manage pricing based on supply, demand and available storage capacity. Selected participants will begin the testing phase towards the end of next year.

The U.S. Geological Survey (USGS) estimates at least 1 million metric tonnes of rare earth element resources within the Khanneshin carbonatite in Helmand Province, Afghanistan. This estimate comes from a 2009-2011 USGS study funded by the Department of Defense’s Task Force for Business and Stability Operations (TFBSO).
The Khanneshin carbonatite contains a major potential source of light rare earth elements (LREE), such as lanthanum, cerium, and neodymium. The LREE prospects in the Khanneshin carbonatite are comparable in grade to world-class deposits like Mountain Pass, CA, and Bayan Obo in China, both of which primarily contain LREE. (more…)
The U.S. was one of the fastest-growing wind power markets in the world in 2009, second only to China, according to a report released today by the U.S. Department of Energy and prepared by Lawrence Berkeley National Laboratory.(more…)
