Ener­gy net­works and their ope­ra­tors, rene­wa­ble ener­gy and its pro­du­cers, power plants and their technology

Tiny houses under electricity

Tiny houses under electricity

They are gray, they are incon­spi­cuous, they are ever­y­whe­re – and when it comes to electri­ci­ty, not­hing works without them. The­re are around 600,000 trans­for­mer or local net­work sta­ti­ons in…

Lithi­um is the gold of the 21st cen­tu­ry. The modern world deman­ds its use on a mas­si­ve sca­le, for examp­le in lar­ge-volu­me bat­te­ries. How nice it would be if the…

It does not work without Chile

The visi­on of an All Electric Socie­ty, in which fos­sil fuels are repla­ced by intel­li­gent­ly net­wor­ked rege­ne­ra­ti­ve ener­gy genera­ti­on, can­not be rea­li­zed without Chi­le. Chi­le is the world’s lar­gest cop­per…

Spe­cial issue of the UPDATE

With the growth of rene­wa­ble ener­gies, the limits of wind power plants are pushing fur­ther and fur­ther into regi­ons that are not without their pit­falls in terms of cli­ma­te. When…
Fit­ness for the water pipeline

Fit­ness for the water pipeline

Water is a food­s­tuff. When it comes out of the tap, it’s even very inex­pen­si­ve, as it cos­ts an average of just 0.2 cents per liter. But the­re is ano­t­her…
Solar on wet feet

Solar on wet feet

When it gets too nar­row for the solar power plants on land, they go out on the water. At least that’s the case near the Dut­ch town of Zwol­le. Sta­ble…

What does INGO do?

INGO is small, rect­an­gu­lar and very red. And it is use­ful. Becau­se rene­wa­ble ener­gies can be so exhaus­ting. They make com­ple­te­ly new deman­ds on the finely balan­ced sys­tem of the power…

Nez­zy – the Loch Geest­land monster

Until now, wind tur­bi­nes have been con­si­de­red a rock-solid affair. Ancho­red unsha­ka­b­ly in the ground, the tower, the mova­ble nacel­le and the three rotor bla­des defy the for­ces of wind…

Craft­s­manship at the Abyss

What use is the most func­tio­n­al, prac­ti­cal and cle­ver sys­tem, the most sophisti­ca­ted con­trol elec­tro­nics and the most sophisti­ca­ted sen­sor tech­no­lo­gy if they are not atta­ched by expert hands whe­re…
