Despite these large-scale construction programs for nuclear and fossil plants, hydropower still accounts for about one-fourth of new facilities being built around the world. Proponents argue that it utilizes a renewable energy source and is less risky for the environment. Of course, there are strong groups that oppose dams on environmental grounds. Work is proceeding on one of the largest projects in the world -- China's much-discussed Three Gorges Dam and hydro plant. Other hydro projects include:
Portugal -- $1.8 billion Alqueva project.
Canada -- $8 billion Churchill Falls project in Newfoundland.
Switzerland -- $2.8 billion Grimsel West station.
Congo (Zaire) -- Grand Inga project.
Brazil -- Lajeado project in Tocantins.
Pakistan -- $1.4 billion Kohala project near Muzafdfarabad, Azad Kashmir.
Pakistan -- $1.3 billion Jehlum River project in Azad Jammu.
Brazil -- $2 billion Tucurui plant expansion.
Syria -- Al-Wehda Dam on Yarmouk River.
China -- $4.8 billion Xiaolangdi project on Yellow River.
China -- $1.4 billion Xiluodu plant on Yangtze River, Sichuan and Yunan provinces.
China -- Hongshui River plant in Guangxi Zhuang Autonomous Region.
Brazil -- Ita project on Uruguay River.
Oil and Gas Projects
Also important in meeting energy needs are projects that find, gather, process and deliver oil and gas. There are now under way several dozen new multibillion-dollar refineries, pipelines, LNG plants, and gathering networks in various parts of the world. One of the most hotly contested projects in the proposed pipeline from Kazakhstan to Turkey. Other projects include:
Mexico -- PEMEX expansion program involves 10 new refineries and plants.
Nigeria -- $1.2 billion LNG plant at Bonny Island.
Viet Nam -- Nation's first oil refinery being built in Quang Ngai province.
Venezuela -- $2.5 billion expansion of the Maraven Refinery.
Qatar -- $6 billion plan for increasing natural gas output.
Korea -- $1.6 billion LNG project at Inchon.
Sweden -- $5 billion Nordic gas grid project.
USA -- $3.5 billion pipeline for oil and fiber-optic cable from Los Angeles to Midland, Texas.
Indonesia -- $1.7 billion complex at Tuban.
Oman -- $2 billion LNG project.
Trinidad -- $1 billion LNG plant at Point Fortin.
India -- $3.5 billion refinery complex in Gujarat State.
Germany -- WINGAS pipeline and underground gas storage facility.
Canada -- $3 billion Syncrude plant expansion at Fort McMurray.
Algeria -- $3.5 billion development of In Salah gas field.
Cameroon -- $3 billion port and pipeline to Chad.
Canada -- Proposed $2.6 billion gas pipeline from British Columbia to Chicago.
Alternate Energy Sources
While traditional power systems dominate the world scene today, there are a number of serious undertakings to develop alternate sources. There are a growing number of large wind farms. There are a few Ocean Thermal Energy (OTEC) projects, and there is growing interest in wave-power plants. However, most interest seems to be associated with new developments in fuel cells.
Much fuel cell research relates to potential utilization in automobiles and other vehicles. However, the technology has advanced to the point that larger units are being installed to meet power needs of hospitals and industrial facilities. Perhaps the first breakthrough into large units will be in Iceland, using that nation's huge supply of thermal energy to produce hydrogen. The government is promoting a program to transform Iceland into a hydrogen economy/society by 2040.
