Can photovoltaic energy create a full EROEI?

Data are available from several years of photovoltaic energy experience in northern Europe. These are used to show the way to calculate a full, extended ERoEI. The viability and sustainability in these latitudes of photovoltaic energy is questioned. Use of photovoltaic technology is shown to result in creation of an energy sink.

What is energy invested for EROEI?

There are many definitions of the energy invested for the ERoEI. The article “Year in review-EROI or energy return on (energy) invested” ( Murphy and Hall, 2010) outlines some definitions for the EI such as: The energy required to collect, deliver, and use that energy.

What is energy return on Energy Invested (EROEI)?

In the present paper, the case of photovoltaic power sources in regions of moderate insolation is analysed critically by using the concept of Energy Return on Energy Invested (ERoEI, also called EROI). But the methodology for calculating the ERoEI differs greatly from author-to-author.

What is Eroi in physics?

EROI tells us about how much energy is obtained from a system of an energy source compared to how much of that energy is required to create and implement the system. Hence, EROI is a unitless ratio of the energy returned to the society to the energy required to make that energy (i.e. embedded energy).

Can the EROEI ext approach be applied to all energy sources?

We recommend that the ERoEI EXT approach be applied to all energy system sources, including nuclear energy. Therefore, the standards and protocols such as those recommended by the International Standards Organisation (ISO) and the International Energy Agency (IEA) can only be partially applied for the better calculation of the ERoEIEXT.

What does EROEI stand for?

The article “Year in review-EROI or energy return on (energy) invested” ( Murphy and Hall, 2010) outlines some definitions for the EI such as: The energy required to collect, deliver, and use that energy. Most ERoEI analyses are not very clear in defining the system boundary for the energy invested.
