The Worlds Biggest Green Energy Projects The Worlds Biggest Green Energy Projects Presentation Transcript

  •  As the world struggles to get more of its power from renewable sources amid rising demand for electricity, renewable energy projects are growing. This is especially true in China, which has plans for a solar thermal farm, a solar photovoltaic farm and a wind farm that are five times to 30 times bigger than the world's current largest. In the U.S. and elsewhere in the world, building bigger plants can be tricky. Though economies of scale help to reduce the cost per watt of bigger projects, bigger projects are riskier to finance. Here are today's biggest projects, from highest capacity to lowest, by type of generation.
  •  Three Gorges Dam, China  Capacity: 18,000 MW  Year completed: 2008  This isn't just the biggest renewable energy project in the world, it's the biggest electricity-generating project, period. It has 32 main generators. More are being added, and final capacity will be more than 20,000 MW. All that power comes at a cost: More than a million people are said to have been displaced by its construction.
  •  The Geysers, Northern California, U.S.  Capacity: 1,000 MW  First power produced: 1921  "The Geysers" aren't actually geysers, but an underground steam reservoir nestled in mountains 70 miles north of San Francisco. The steam powers 22 power plants at the site, 15 of which are owned by Calpine. The Geysers' steam first started producing power in 1921, but the field wasn't developed commercially until the 1960s.
  •  Roscoe Wind Farm, West Texas, U.S.  Capacity: 782 MW  Year completed: 2009  Roscoe, now run by the German utility E.On, overtook another West Texas farm, the Horse Hollow Wind Energy Center, last fall. It will soon be overtaken itself- -if it hasn't been already. China is developing a wind corridor in western Gansu province that is planned to ultimately grow to a staggering 20,000 MW. By the end of this year, it is scheduled to reach 5,000 MW.
  •  Solar Energy Generating Systems, Mojave Desert, Calif., U.S.  Capacity: 354 MW  Year completed: 1990  This system, known as SEGS, is a collection of nine plants that redirect the sun's heat to tubes of synthetic oil. The heat in the oil is transferred to water, producing steam that turns a turbine. Bright Source Energy is planning a bigger 440 MW solar thermal project, also in the Mojave Desert. But these plants seem quaint compared with a Chinese plan announced this month to build a series of solar thermal plants in the Mongolian desert designed by eSolar that could reach 2,000 MW.
  •  Jakobstad Biomass Power Plant, Ostrobothnia, Finland  Capacity: 240 MW  Year completed: 2001  Biomass plants are simple--they burn vegetation for heat that is used to spin a turbine. What keeps them small is simple, too: logistics. It's hard to gather and transport the amount of biomass it would require to power a plant the size of, for example, a coal plant.
  •  Rance Tidal Power Station  Brittany, France  Capacity: 240 MW  Year completed: 1966  Tide mills have been employed for centuries. A tide coming or going turned a water wheel that powered a mill. The Rance station produces power more like a hydroelectric plant--the pressure of water flowing turns cylindrical turbines. A newer approach calls for submerging huge spinning blades that look a lot like wind turbines, called axial turbines. But the next big tidal power station will likely be South Korean, and work like the Rance plant: A 254-MW project called the Shiwa Lake Tidal Power Station is scheduled to be completed this year.
  •  Horns Rev 2 Farm, Denmark  Capacity: 209 MW  Year completed: 2009  This farm, owned by Denmark's Dong Energy, became the largest offshore wind farm in the world when it was completed in the blustery North Sea last fall. It's a small part of Europe's much bigger hopes for offshore wind. The European Wind Energy Association is targeting 40,000 MW of offshore wind in Europe by 2020, up from 1,500 now.
  •  Rozenburg Waste-To-Energy Plant, Netherlands  Capacity: 108 MW  Year completed: 1972  The simple way to turn trash into power is to burn it and use the heat to turn a turbine, the same way you'd burn coal or biomass. The problem with trash is that it's, well, trash. The emissions from these can be nasty and must be scrubbed hard to clean them. Other trash- to-energy approaches include gasification that can produce either electricity or ethanol
  •  Olmedilla Photovoltaic Park , Olmedilla, Spain  60 MW  2008  A solar photovoltaic cell is a wonderfully elegant device. Without any moving parts it simply transforms the photons emitted from the sun into electrons that can run our lives. The problem, however, is gathering enough photons. The world's biggest field is just 60 MW. That's about to change. Several larger plants are planned, both in the U.S. and abroad. The really big plans, of course, are Chinese. The first phase of a gargantuan project that is expected to create a 2,000- MW field of First Solar thin film panels by 2019 gets underway this summer
  •  Aguçadoura Wave Farm, Portugal  2 MW  First installed: 2008  This was the first and only commercial wave energy power plant, consisting of connected sections of tubes that, when jostled by the waves, created hydraulic pressure which was used to create electricity. That was before the devices broke. Now they are awaiting repairs that have been delayed because the plant's owner, Babcock & Brown, is being liquidated. Pelamis, which builds the devices, now has its sites on tastier waves: It has teamed with Sweden's Vattenfall to build a 20MW project off the Shetland Islands.
