In the past the ERoEI of our primary energy sources — oil, gas and coal — was so high, probably over 50, that there was bucket loads of cheap energy left over to build all the infrastructure and to feed all the people that now inhabit The Earth.
Solar power here is costly for consumers because of high state-mandated prices. But there appears to be one major omission and that is the energy cost of distribution. The MPs wanted to have a solar feed-in-tariff.
Do you simply measure the electricity used at the PV factory, or do you include the energy consumed by the workers and the miners who mined the silicon and the coal that is used to make the electricity? One reason for this is that the current paper  is specifically for temperate latitude solar.
Utilities say their infrastructure cannot handle the swelling army of solar entrepreneurs intent on selling their power or handle the fluctuating output of thousands of mostly small solar producers.
And this random orientation will undoubtedly lead to serious degradation of the ERoEI. To kick start the solar revolution, the Spanish government promised massive subsidies to solar PV providers at 5. Looking only at cloudy, high temperate latitudes will substantially degrade that number.
As a tenured professor not funded by any special interests, he is one of the most respected, cited, and unbiased scientists writing on EROI. Solar lobbyists like to dazzle the public with impressive figures on the capability of solar energy.
But this is pure theory. But with the net energy equation for solar PV looking like this: Far more money went into promoting and selling solar investments than research and development.
I dare say leaving the panels in their box would make little difference to their output. Hall and others have since estimated the EROI for various power sources, a difficult analysis that requires identification of all energy inputs to power production.
A realistic look at solar PV can give us better ideas of how to cope in the future. And if you want health care, you need There is a large financial cost and energy cost to compensate for this that RE enthusiasts dismiss with a wave of the arm.
The manufacture of PV panels involves lots of nasty chemicals too: These large installations are far less expensive and more efficient than rooftop solar-PV. Also, too much output can fry electrical components at various locations in the grid.
Materials to make panels but also to erect and install panels Labour at every stage of the process from mining manufacture and disposal Manufacturing process i. Brussels we have a problem!
At the point where ERoEI reaches 1, everyone is engaged in gathering energy and society as we know it collapses! It is a concept that is alien to most individuals, including many engineers, energy sector employees, academics and policy makers. Prieto and Hall added dozens of energy inputs missing from previous solar PV analyses.
It is based on 3 years of real data from all the PV facilities in Spain. More on that later. Concluding comments The findings of this single study suggest that deploying solar PV at high latitudes in countries like Germany and the UK is a total waste of time, energy and money.

Task 1 activities are organized into the following subtasks: SUBTASK Status Survey Reports A published report, Trends in Photovoltaic Applications, is compiled from the National Survey Reports (NSRs) produced annually by all countries participating in the IEA-PVPS Programme. IEA - PVPS Task 12, Subtask 2.

A new study by Ferroni and Hopkirk  estimates the ERoEI of temperate latitude solar photovoltaic (PV) systems to be If correct, that means more energy is used to make the PV panels than will ever be recovered from them during their 25 year lifetime.
