The reason for this is something called an "availability factor" (i.e., the number of hours a generating unit runs), where typically, solar and wind resources have low availability factors which are usually associated with natural gas or oil peaking and intermediate dispatch units.
This last point is important as coal fired power plants in the U.S. are responsible for 82% of CO2 emissions from total electricity generation.
Today, we will summarize these 3 key points by
From carbon sequestration work performed with the University of Florida on fast growing trees, we found that a volume of below ground biomass equal to ~60% of the above ground mass was being created. However, we must note that our findings of terrestrial carbon sequestration are significantly higher than found in other research. Because of this, we include carbon sequestration rates derived from a U.S. Department of Energy study performed in North Carolina in the table below -- providing a range of .24 (DOE estimate) to .64 (our research findings estimate) tons per Mwh.
Conclusion: When biomass energy is developed in an environmentally sustainable way as base load power generation (displacing coal use), the CO2 benefits can be ~4 times greater than solar power displacing natural gas peaking technology.
