Where can I find the life cycle energy analysis for the solar electric, solar hot water, wind generated electric, and other renewable energy products on the market today?
A calculated lifecycle energy cost is essentially a moving target.
This is a difficult question to answer, as there are many technologies with different production processes and materials which are constantly changing. Any calculated lifecycle energy cost is essentially a moving target, and values will continue to fall as the technologies become more energy and resource efficient. That said, here are some good resources for consideration:
Home Power: PV Energy Payback
National Renewable Energy Lab: PV FAQs
Energy Bulletin: Energy Payback of RoofMounted PV Cells
Renewable Energy World: Assessing the Life Cycle of Wind Turbine Production
Certified Site Assessors learn how to utilize a lifecycle cost modeling tool and can help point customers in the right direction. Learrn more about the site assessment process and costs.
