Summary: Biomass can be converted to various bioenergies through different conversion technologies, and carbon capture can be applied to reduce CO2 emissions. The optimal conversion technology and level of carbon capture depend on constraints and parameters. Pyrolysis and gasification are the most cost-effective methods for producing liquid fuels, while electricity and hydrogen have lower costs per unit of forward motion. Gasification to electricity is currently the best option for greenhouse gas mitigation, but gasification to hydrogen is expected to be more effective in the future.

Summary: Remote community initiatives for renewable energy in Canada are rapidly increasing, but with different numbers, success rates, and strategies. Coordinating technology deployment and long-term policies is critical to meet low-carbon transition goals. Renewable resources can provide subsidized energy, create sustainable infrastructure, and enhance economic viability in integration with social values. The transition to renewable energy is crucial for sustaining remote and indigenous communities in Canada by providing local, clean, and low-carbon emission energy. This paper identifies 635 renewable resource projects deployed to improve electricity supply and highlights the achievable goal of balancing demand and sustainable development before and after 2050 through energy efficiency and social value.

Summary: As the global population grows, the demand for food, energy, and water will increase significantly. However, limited land availability and competition for solar resources pose challenges to resource generation technologies. In the United States, both agriculture and solar energy production have adopted densification schemes to improve yields and energy output per unit of land. This research proposes an Agrivoltaic food and energy coproduction architecture that optimizes power generation while maintaining crop productivity by implementing ideal anti-tracking during critical growth periods. This technology offers a viable pathway for widespread solar implementation throughout the contiguous United States.
