Musk stoked intense interest in Tesla's desire to help South Australia – while generating publicity for its new line of grid-connected batteries – by publicly standing behind his cousin's offer. The real attention-getter was the payoff if their company fails to meet the deadline – Musk promised that the system will be free if it is not operational within 100 days after the contract has been signed.
In 2017, Germany generated 37 percent of its electricity from non-carbon sources.[1] In pursuing the Energiewende, Germany will have invested $580 billion in renewable energy and storage by 2025.
If Germany had invested in nuclear instead, it could have built 46 1.6 GW EPR reactors at the $12.5 billion per reactor cost of the U.K.’s Hinkley Point C. German companies assisted with the design of the EPR and the reactor was explicitly planned to meet the strictest European regulations.
In this scenario, EP assumes that a Germany pursuing nuclear power would maintain the same level of nuclear generation as it produced annually before implementing its nuclear phase-out in 2011, about 133 TWh per year.
With 46 EPRs operating at 90 percent capacity factor, Germany could first eliminate all coal, gas, and biomass electricity, then make up for today’s 150 terawatt-hours per year of wind and solar from its renewables investment, all while exporting 100 terawatt-hours of electricity to its neighbors (double 2017’s actual exports). Finally, with the remaining 133 terawatt-hours, Germany could decarbonize its entire light vehicle fleet including all 45 million of its passenger vehicles.[2]
Had California and Germany invested $680 billion into new nuclear power plants instead of renewables like solar and wind farms, the two would already be generating 100% or more of their electricity from clean (low-emissions) energy sources, according to a new analysis by Environmental Progress.
The analysis comes the day before California plays host to a “Global Climate Action Summit,” which makes no mention of nuclear, despite it being the largest source of clean energy in the U.S. and Europe.
Here are the two main findings from EP's analysis:
Had Germany spent $580 billion on nuclear instead of renewables, and the fossil plant upgrades and grid expansions they require, it would have had enough energy to both replace all fossil fuels and biomass in its electricity sector and replace all of the petroleum it uses for cars and light trucks.
Had California spent an estimated $100 billion on nuclear instead of on wind and solar, it would have had enough energy to replace all fossil fuels in its in-state electricity mix.
As a result of their renewables-only policies, California and Germany are climate laggards compared to nuclear-heavy places like France, whose electricity is 12 times less carbon intensive than Germany’s, and 4 times less carbon intensive than California’s.
Thanks to its deployment of nuclear power, the Canadian province of Ontario’s electricity is nearly 90% cleaner than California’s, according to a recent analysis by Scott Luft, an energy analyst who tracks decarbonization and the power sector.
California’s power sector emissions are over twice as high today as they would have been had the state kept open and built planned nuclear plants.
California’s political establishment pushed hard to close San Onofre nuclear plant in 2013 — triggering an on-going federal criminal investigation — and later to close Diablo Canyon nuclear plant, which generates 15% of all in-state clean electricity, by 2025.
Had those plants been constructed and stayed open, 73% of power produced in California would be from clean (very low-carbon) energy sources as opposed to just 34%. Of that clean power, 48% would have been from nuclear rather than 9%.In 2016, renewables received 94 times more in U.S. federal subsidies than nuclear and 46 times more than fossil fuels per unit of energy generated. Meanwhile, a growing number of analysts are admitting that an electricity grid that relies on nuclear power has no need for solar and wind. More troubling, adding solar and wind to a nuclear-heavy grid would require burning more fossil fuels, usually natural gas, as back-up power
