It is important to understand that for each LPOE site, a technology is only counted here if it is part of the optimized combination of RE solutions for that site. In other words, it is possible for an LPOE site to have the potential to generate biomass energy cost effectively. However, if it is more cost-effective to generate wind energy and use solar water heating at that LPOE site, then biomass energy will not be counted as an optimized technology for that site. Further more, the number of technologies counted in this table does not reflect the total amount of energy that each region has the potential to generate.
