Renewable Energy Cannot Substitute for Nuclear:
A Perspective on Meeting Power Generation Needs in Georgia, USA
The often-discussed issue of replacing nuclear with solar or wind is a false choice—solar and wind energy cannot substitute for nuclear energy. With respect to how we should move forward in our energy policy, everyone is entitled to their own convictions, but not their own math and not their own science and engineering.

Renewable Energy: Enabled by, Not Competitive With, Nuclear and Fossil Fuels
Overstating renewable energy’s potential and real contribution toward meeting the dual challenges of reducing global carbon emissions and providing reliable energy for developing economies over the next 35 years cannot mask the reality that zero-carbon power generation shares are decreasing globally or that solar and wind are not cost-competitive with nuclear and fossils.

Natural Gas and Renewables:
Lessons from California on Overdependency
But for the grace of nuclear, there go we.
“The whole is greater than the sum of its parts” isn’t holding true in California’s ongoing experiment with natural gas and renewables, and it should serve as a warning to states that see gas and renewables as their lifeline to a reliable, low-carbon future. The warning being that the individual attributes of natural gas and renewables are adding up to an overdependency that is creating problems.

Nuclear vs. 100% Renewable Energy: An Unnecessary Battle
The debate around carbon emissions and the energy path forward should be a deliberation that acknowledges realistic constraints and concedes that whichever path we take will require trade-offs since there is no zero-risk technology. In the case of the daunting energy-climate-economic issue staring us squarely in the face and the global scale at which we’re trying to work, prudence and pragmatism would call for negotiation and compromise. But that doesn’t seem to be an option with the 100% renewable energy movement. Instead, its supporters have mandated a false choice between two necessities that are not mutually exclusive. Two perfectly compatible zero-carbon energy resources, nuclear and renewables, have been forced into the center ring of an unnecessary and regrettable battle, even though both resources are needed. Not everyone wants this death match to continue—some of us want the fight to stop with both declared as winners, still standing and ready to fight the bigger battle of reducing carbon emissions, providing dependable electricity to billions living in energy poverty and supporting global economic development.

RENEWABLES, NUCLEAR OR BICYCLES?
Want to Reduce CO2 by 35%? Ride a Bicycle…Or, Build a Nuclear Power Plant.
It’s commonly reported that electricity production is the largest source of CO2 in the U.S. That’s barely the case.
In 2013, the U.S. emitted 5,278 mmtons of CO2. A breakdown of CO2 emissions per sector (Table 1) indicates that the transportation sector contributed 1,740 mmtons of CO2 (33% of U.S. total) while electric power contributed 2,022 mmtons (38.3% of U.S. total). The most recent data from the U.S. Energy Information Administration indicate that in 2015 the U.S. emitted 5,271 mmtons of CO2. Of this, the transportation sector contributed 1,869 mmtons (35.5% of U.S. total) while the electric power sector contributed 1,925 mmtons (36.5% of the U.S. total). Recent emission trends have been up for the transportation sector and down for the power sector (Figure 1). Continue reading “Renewables, Nuclear, or Bicycles?”
OREGON PASSES LAW, BANS COAL: A BROADER PERSPECTIVE
Scattered between our current energy economy and a future lower emission energy economy are numerous and varied obstacles that present society with formidable challenges. Some are technical; some are social, economic and political. Yet others are a wicked complex of all the above with serious implications for overly simplified solutions that fail to account for these complexities. As such, if society is to transition from where it is today to a much different day in the future, the space in between now and then must be strategically navigated and the challenges must be met and resolved. We can’t just be there…we have to get there. And getting there will require nuclear, natural gas, renewables, and advanced coal technologies ( e.g., CCS, IGCC).
Moreover, not every state and country should be required by law to get there the exact same way. To do so would reflect an egregious misunderstanding of economic development, power generation and the ongoing challenges facing the industry.

THE OTHER FACE OF ENERGY
The face of climate change just got a lot cuter. It also got a name. Nora the polar bear was introduced a couple of weeks ago at the Columbus Zoo and Aquarium in Powell, Ohio and has been touching hearts ever since, particularly the hearts of global climate activists who see Nora as a way to draw attention to climate change.

AMERICA NEEDS AN EXCEPTIONAL PRESIDENT…
AND SO DOES THE WORLD
(Written and posted, January 2016; A post-primary paragraph is appended)
Beginning to emerge are the outlines of a new era that resembles less the twentieth century than the nineteenth. Ours is a world of constant flux, shifting alignments, numerous power centers, and states coming together and apart—all with an overlay of modern technology and globalization. The potential for disorder is considerable, and will only be ameliorated through the concerted efforts of many of the world’s most powerful countries led by the United States, the only country now and for the foreseeable future with both the capacity and the tradition of working on behalf of broader global arrangements to the benefit of others as well as itself. The question is whether the United States will continue to be that country, something that will require discipline in what America does at home and wisdom in what it does abroad.

CLIMATE ACTIVISTS DISAGREE
For my first post of the New Year I settled on nuclear as it’s the optimal resource for energy systems in society—energy dense, dispatchable, zero-emissions, and technologically advanced and the resource itself is cheap. It’s my sincere hope that the debate on the growth and development of nuclear power in the U.S. will be broached this year with rationale, logic, sobriety, and common sense given the challenges we’re facing. There is too much at stake and we have too many environmental constraints and economic goals in play to allow this resource to fade away or simply disappear from our industrial DNA while other countries throughout the world wisely invest in it and leverage its benefits in growing and developing their own economies.
