U.S. can cut oil imports to zero by 2040, use to zero by 2050
(3/29/2007) The United States could dramatically cut oil usage over the next 20-30 years at low to no net cost, said Amory B. Lovins, cofounder and CEO of the Colorado-based Rocky Mountain Institute, speaking at Stanford University Wednesday night for a week-long evening series of lectures sponsored by Mineral Acquisition Partners, Inc.


Air pollution may reduce wind power, rainfall
(1/22/2007) Aerosolized particles and other pollution produced from vehicle exhaust may reduce wind speeds near Earth's surface, resulting in less wind for power generation as well as reduced precipitation, according to a study published in the December 27th online edition of Geophysical Research Letters by researchers at Stanford University and NASA.


Geothermal energy could cut U.S. oil demand
(1/22/2007) Geothermal energy could eventually power some 25 million homes across the United States at a cost of $40 million per year according to a Department of Energy sponsored study released Monday. Lead by Jefferson Tester, a professor at MIT and lead author, the report argues that unlocking the heat stored in Earth's crust could improve American energy security while reducing emissions greenhouse gases blamed for global warming.


China to build world's largest solar power plant
(11/21/2006) China plans to build the world's largest solar power station in the northwestern province of Gansu according to a report from Xinhua, China's state news agency. Construction of the 100 megawatt facility will take five years and cost 6.03 billion yuan ($766 million).


Renewable sources could power 25% of U.S. energy needs by 2025
(11/13/2006) Renewable energy sources could supply one quarter of America's electricity and motor vehicle fuel needs by 2025 according to a new study from RAND, a nonprofit research organization. Currently six percent is energy used in the United Stats comes from renewable sources like solar, biomass, hydroelectric, tidal, wind, and geothermal.


Solar Energy Powers Mainland China's Richest Man
(10/12/2006) The largest private fortune in mainland China may belong to Shi Zhengrong, the founder of the China's largest producer of photovoltaic equipment used to convert sunlight into eletricity, according to an article in today's edition of The Wall Street Journal.


US has low-cost alternatives to oil; peak oil frenzy and human-induced climate change avoidable says Columbia University
(5/14/2006) Surging oil prices have fueled calls for the United States to develop new sources of affordable and secure domestic energy. While renewable energy -- especially biofuels, wind power, and solar technologies -- is an area of particular interest, researchers from the Earth Institute at Columbia University say that the U.S. already has relatively low-cost alternatives to imported oil, including coal, tar sands, and oil shale. These resources can be extracted and used at a lower cost to the environment than some might expect. In a report published in the most recent issue of Brookings Papers on Economic Activity, Klaus S. Lackner and Jeffrey D. Sachs argue that "coal alone could satisfy the country's energy needs of the twenty-first century." They say that "coal liquefaction, or the process of deriving liquid fuels from coal, is already being used in places and with expanded infrastructure could provide gasoline, diesel fuel and jet fuel at levels well below current prices." Further, Sachs and Lackner suggest that "environmental constraints such as increased carbon dioxide emissions arising from greater use of coal and other fossil fuels could be avoided for less than 1 percent of gross world product by 2050," a sum far less than others have estimated.


Wind turbines could power China says expert
(3/9/2006) Wind could become China's second-largest source of electricity according to a Chinese energy expert. Wang Weicheng, an energy professor at Tsinghua University in Beijing, told reporters that China has the potential to install up to 100 gigawatts of wind power. Wang's comments come as China has been aggressively expanding its interests in renewable energy sources including wind, solar, biofuels, tidal, and small hydroelectric dams.


California adopts massive solar energy project
(1/13/2006) The California Public Utilities Commission approved a $2.9 billion program to make the state one of the largest producers of solar power in the world.


Businesses can now host solar energy project without up-front costs
(12/21/2005) 3 Phases Energy Services announced today its launch of a new service, "Daylight Savings", a model for financing large-scale solar photovoltaic (PV) projects. Daylight Savings allows businesses and institutions to host onsite photovoltaic systems while eliminating all up-front capital requirements and providing a long-term hedge against fossil fuel prices.


Scandinavians mix sea and river water to generate electricity
(12/19/2005) Two Scandinavian groups have invented devices that generate electricity by mixing sea and river water. The technologies work based on the difference in salt concentration between ocean water and freshwater.


Making wind power less deadly for birds
(12/15/2005) High oil prices and concern over climate change are driving interest in renewable energy technologies. All types of potential power sources -- not limited to the sun, ocean tides and waves, raw sewage, and even insects -- are the focus of media reports, while governments and industry scramble to announce their grand plans for adopting green energy.


California plans $3 billion for solar energy projects
(12/13/2005) Tuesday the California Public Utilities Commission announced an ambitious program to expand the market for solar power, proposing to provide $2.8 billion of incentives toward solar development over the next 11 years.


China to add wind power capacity
(8/15/2005) China plans to construct its first offshore wind power complex next year in hopes of easing chronic electricity shortages, the official Xinhua News Agency reported Monday.


China funds massive palm oil plantation in rainforest of Borneo
(8/12/2005) Plans to create the world's largest palm oil plantation along Indonesia's mountainous border with Malaysia could have a devastating impact on the forests, wildlife and indigenous people of Borneo, warns World Wildlife Fund.


Renewable energy in China, a strategic future?
(8/2/2005) China's failed bid for American petroleum firm Unocal may prompt it to further focus on its development of alternative energy sources.
