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

(05/14/2006) 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.

High oil prices fuel bioenergy push

(05/09/2006) High oil prices and growing concerns over climate change are driving investment and innovation in the biofuels sector as countries and industry increasingly look towards renewable bioenergy to replace fossil fuels. Bill Gates, the world's richest man, has recently invested $84 million in an American ethanol company while global energy gluttons ranging from the United States to China are setting long-term targets for the switch to such fuels which potentially offer a secure domestic source of renewable energy and fewer environmental headaches. Biofuels are fuels that are derived from biomass, including recently living organisms like plants or their metabolic byproducts like cow manure. Unlike fossil fuels -- like coal, petroleum, and natural gas, which are finite resources -- biofuels are a renewable source of energy that can be replenished on an ongoing basis. In general, biofuels are biodegradable and, when burned, have fewer emissions than traditional hydrocarbon-based fuels. Typically, biofuels are blended with traditional petroleum-based fuels, though it is possible to run existing diesel, engines purely on biodiesel, something which holds a great deal of promise as an alternative energy source to replace fossil fuels. Further, because biofuels are generally derived from plants which absorb carbon from the atmosphere as they grow, biofuel production offers the potential to help offset carbon dioxide emissions and mitigate climate change.

Wind turbines could power China says expert

(03/09/2006) 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

(01/13/2006) 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.

Private industry will embrace green energy says Australian govt

(01/11/2006) US Energy Secretary, Samuel Bodman, told the Asia-Pacific Partnership on Clean Development and Climate--a rival to the Kyoto Protocol on limiting greenhouse gas emissions--that the private sector will solve the problem of climate change.

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

(08/15/2005) 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

(08/12/2005) 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?

(08/02/2005) China's failed bid for American petroleum firm Unocal may prompt it to further focus on its development of alternative energy sources.

China announces wave power station changes

(07/27/2005) China announced that it has developed typhoon-resistant technologies for the world's first experimental wave power station. The announcement comes two months after a Norwegian firm signed an agreement to construct a commercial wave farm to harvest electricity from sea swells off the coast of Scottland.
