Make green energy more efficient, reliable and safe - Case study
Distributed, intermittent renewable power sources create natural load and phase imbalances at the interconnect to the grid. This results in a degradation of efficiency (loss of revenue), equipment life (higher replacement costs), and power quality (“dirty power” that damages rate payer electronics). These effects represent increasing challenges as the percentage of renewable sources ...

Can economic growth pressure green energy projects
The EU has set itself an enormous Green energy policy challenge over the next decade which will involve massive capital investment into new technologies, huge investment in grid infrastructure, as well as replacement of existing capacity as older plants reach the end of their life. But with the Economy now once again in growth and thus the demand for Energy rising, will such massive change be ...

Intermittency of wind: the wider picture
This paper puts the discussion on intermittency of wind into its wider context: in the first part, it reviews the natural variability of all resources that power renewable energy technologies. This highlights how intermittency of wind influences the degree of variability relative to other renewable energy technologies, but does not change its kind. In the second part, management options for ...
