Renewable energy return on investment
Energy Return on Investment (EROI) is a ratio for describing a measure of energy produced in relation to the energy used to create it. For instance the ratio would illustrate how much energy is used.
EROI is important because if the cost of an energy plant is more than the revenues gained from selling electricity, that plant is not economically viable. EROI can also help organizations and governments.
There are a number of consumable energy sources where EROI is determined for efficiency and cost analysis. These energy sources include oil, biofuels, geothermal energy, nuclear fuels, coal, solar, wind, and hydroelectric. The average EROI across all generating technologies is about 40 for the United States, according to the World.
The issue is still subject of numerous studies, and prompting academic argument. That's mainly because the "energy invested" critically depends on technology, methodology, and system boundary assumptions, resulting in a range from a maximum of 2000 kWh/mof module area down to a minimum of 300 kWh/mwith a median value of 585 kWh/maccording to a meta-study from 2013.
As the photovoltaic (PV) industry continues to evolve, advancements in Renewable energy return on investment have become critical to optimizing the utilization of renewable energy sources. From innovative battery technologies to intelligent energy management systems, these solutions are transforming the way we store and distribute solar-generated electricity.
