Poor sound on this video, but good information. From the UK but relevant everywhere.
Description:
Why is renewable generation not resulting in cheaper energy prices? This is one of the most common questions we hear from energy consumers. After all, the ‘fuel’ required to generate power from solar panels or wind turbines is free. The answer though is far more complex. So to explain the underlying rationale in clear and straightforward terms, we recorded a three-minute conversation between our Senior Costing and Risk Manager, Stephen Evans, and wholesale energy trader, Mark Ursell, from our Optimisation Desk at npower Business Solutions.

Those times when there are big blobs of wind and solar under the supply line are the times we should celebrate how much fossil emissions are being displaced.
