Concentrated solar power is a water hog

CSP focuses the heat of the sun onto a central tower to power turbines. Unforunately, it uses more water than any other form of energy generation. This is made worse by CSP plants invariably being located in deserts where water is already scarce. While it is possible to reduce their water usage, this also [...]

Arizona to have world’s largest solar power tower soon

EnviroMission, an Australian company, plans to build the world’s largest solar tower energy plant in the world in Arizona by 2015. When completed, the central tower will be 2,625 feet tall, twice that of the Empire State Building, and one of the tallest structures on the planet.

It will output a substantial 200 MW [...]

Solar Reserve solar power tower

Solar power towers store heat from the sun into molten salt to power steam generators. The salt can be stored for days, then used on demand as needed. Thus the power is available 24 /7.

Solar Reserve already has one existing such plant and is planning a much larger [...]

Spain plugs in largest solar-tower power plant

This solar tower plant in Spain is the world’s largest. The sun reflects off the mirrors onto a receiver in the tower which makes steam from water to power a turbine and create electricity.

Solar power tower

When completed in 2012 this 1000 meter tall solar power tower will be the biggest on the planet.
