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.

Most of the easy energy is gone. Are we heading for a dead end?
(Spoiler alert!) Why is the movie Gravity so scary to some people...?
Even if forecasting the exact date of the peak is a fool’s errand, only a fool would miss the signs that the world oil industry has entered a new, desperate era. Discoveries are down, costs are up. Production has flatlined, environmental impacts from petroleum operations are soaring.
If we have to use fossil fuels to manufacture renewable plants, doesn't it mean that renewables are useless?
In this post, Marco Raugei makes a fundamental point about an often raised question: if we have to use fossil fuels to manufacture renewable plants, doesn't it mean that renewables are useless?
In this article I apply the idea of energy return on energy invested to food production in the United States, and discuss the relevance of energy efficiency to the local food movement.
Under what conditions will a technology be able to survive the energy contraction associated with the depletion of fossil fuels?
The energy returns that fuels offer have broad social and economic implications, as does their decline. This article offers readers a background on energy return as a measure of a fuel's production efficiency, and explores the metric's broader social and economic significance.
EROI studies for most energy resources show a decline, indicating that depletion has been more important than technological improvements over time.
There's Only One Real Option for Averting Economic and Ecological Ruin -- So Why Aren't We Talking About It?
Energy conservation is our best strategy for pre-adapting to an inevitably energy-constrained future. And it may be our only real option for averting economic, social, and ecological ruin.
