Insight and inspiration in turbulent times.
We’ve reached a tipping point where fossil fuels will enter terminal decline, independently of climate policy action. Given climate policy action is also now accelerating, fossil fuels are double dead. To paraphrase Douglas Adams, “So long and thanks for all the energy”.
Using a simple cost model this article shows that PV technologies can indeed supply electricity to the grid for less than 0.10 €/kWh in large swaths of the continent…
This weeks our guest is Dr Marco Raugei. We discuss his work on renewable energy, in particular his work on the current state of Photovoltaic or PV systems.
-Designing the grid for renewables
-Liquid Air: The Birth of the Nitrogen Economy
-Danes set the pace on green energy vision
-California Governor Jerry Brown green lights renewable energy push
-Polls: Voters back clean energy, climate policies
Oil prices fell dramatically this week to $107/barrel for Brent, on worsening economic news from China and Europe, and assurances from Saudi Arabia that it is ready to pump more oil to keep prices down. The speed of the fall on Monday however is something of a mystery and has led to an investigation by the Commodity Futures Trading Commission and the FSA.
A short while back, I described my standalone (off-grid) urban photovoltaic (PV) energy system. At the time, I promised a follow-up piece evaluating the realized efficiency of the system. What was I thinking? The resulting analysis is a lot of work! But it was good for me, and hopefully it will be useful to some of you lot as well.

This book continues the presentation of the Lovins perspective, essentially the claim that there is great scope for conservation measures and alternative technologies to solve our problems and enable maintenance of rich world economies and lifestyles. My notes indicate that it would be far too capital costly for the US to run largely on renewable energy.
Ouse Valley Energy Supply Company, or Ovesco as it is commonly known, is a powerful inspiration for enthusiasts of community renewable energy….Standing on a hill above Lewes you can not only see the solar PV installations completed by Ovesco but also arrays of panels inspired by their projects. The local football club, the leisure centre and many local homes, have all followed the example of Ovesco. Other sites are looking to follow and there are also plans for community wind and hydro-electric schemes.

I have not kept it secret that I’m a fan of solar power. Leaving storage hangups aside for now, the fact that the scale of available power is comfortably gigantic, that perfectly efficient technology exists, that it’s hard-over on the reality axis (vs. fantasy: it’s producing electricity on my roof right now), and that it works well almost everywhere—what’s not to like? Did you trip over that last part? Many do. In this post, we’ll look at just how much solar yield one may expect as a function of location within the U.S.
