Like the Renewable Energy by 2030 report in Energy Journal, this study has a broad portfolio of existing renewable energy sources with geothermal and tidal providing a base load and solar and wind supplementing when available. The study also discounts nuclear power as a dirty and expensive form of energy in the long run and eliminates it from the energy mix. The report supports carbon capture but does not believe that the technology will be mature enough to be economically feasible by the time renewables are in place.
The Energy Report goes further in detailing transportation solutions, social energy equity, and broad conservation as pivotal to the success of the proposal. This means biofuels, vast grid networks and distributed energy generation, and zero energy building and retrofits similar to the Passivhaus standard. The study places great emphasis on reducing energy demand which also lowers costs. Another positive aspect is that while the study notes that the implementation of renewables at such scales is costly, the ongoing energy generation is less expensive than our current system so in the bigger picture, it will not necessarily cost more.
