How To Licence A Home Made Trailer In Ontario
On a cold, large cave beneath an Orthodox Christian cathedral, an energy firm Helsinki is developing a data center expected to become the greenest the planet. Excess temperature of hundreds of computers to be located under the Uspensky Cathedral be captured and channeled by the district heating network of the city , a piping system with water heated designed to keep homes warm in the Finnish capital.
"It is perfectly feasible that a considerable proportion of the heating in the capital may come from the thermal energy generated by computer enclosures," said Juha Sipila, project manager of Helsingin Energia. Finland and other northern European countries are using their networks fed by water as a conduit for renewable energy sources and waste capture used to heat water that is pumped through the system.
is possible that part of the heating may be caused by the heat generated by computers
The new data center computing services company Academica, which will start operations in January next year, is a way address environmental concerns generated by the expansion of the Internet as a central repository of data and processes of the world, known as the "cloud."
A big problem is that in a data center typically only between 40 and 45 percent of the energy used is for computer processes themselves, the rest is used mainly for cooling servers. Data centers like those in use Google about 1 percent of world energy , and demand for energy is growing rapidly.
Emissions of carbon dioxide data centers are located about one-third the number reported by the airlines, but are growing at around 10 percent per year and are approaching the levels of consumption of whole countries such as Argentina or the Netherlands.
addition to providing heating for households in the Finnish capital, the new computer room Uspenski use half the energy of a common data center. Its contribution to the heating network of the city be comparable to a large wind turbine , enough to heat 500 homes large. "Green is a big selling point, but equally important is the cost savings," said Pietari päivänä, commercial director of Academica.
