Lazard Ltd has released its annual in-depth studies comparing the costs of energy from various generation technologies and of energy storage technologies
for different applications.
The cost of generating energy from renewable sources other than solar, such as onshore wind, geothermal, and biomass, declined only at the margins from last year, reflecting both the maturing of technology in those areas and a relatively low level of investment. The median cost of generating energy from offshore wind generation declined approximately 22%, but remains substantially more
expensive than onshore wind facilities, especially in the U.S.
