Apple 100% renewable solar Headquarter in Cupertino

Apple will have a Headquarter 100% powered by Renewable Energies in Cupertino, south San Francisco Bay Area.

The new building will combined on-site fuel cells and use of grid-purchased renewable energy during peak hours, at the same time, the new manufacturing plant in Mesa, Arizona, would also be powered by 100% renewable energies, solar panels and geothermal power source on site.

It seems two big companies of new technologies bet for renewable energies (Google and Apple)...



El agujero Eléctrico alcanza los 4.632 M€ hasta el tercer trimestre en el acumulado anual (Q3/13 YTD)

Parece que se empieza a controlar el agujero Eléctrico español, puesta que existía una desviación negativa hasta junio, en el acumulado anual, realmente está controlado o corresponde al fin de las primas de las Fotovoltaicas puesto que han cumplido el máximo número de horas primadas del año...

IEEE Approves Standard Supporting Low-frequency, Narrowband PLC and Smart-Grid

IEEE approves the updated version of 1901three years later of the first version.

Designed to specify secure PLC at data rates up to 500kbps and at transmission frequencies of less than 500kHz for applications, IEEE 1901.2 addresses low-frequency, narrowband PLC over low-voltage lines of less than 1000V between transformer and meter, through transformer low-voltage to medium-voltage (1000V up to 72kV) and through transformer medium-voltage to low-voltage power lines in both urban and in long-distance (multi-kilometer) rural communications.

Will achieved this standard the technical conditions for taking off smart grids communications by Power Lines with the properly Quality of Service (QoS)?
