Excluding Nuclear, Fossils With Carbon Capture, & Biofuels From The Green New Deal Makes Financial & Climate Sense

The Green New Deal and multiple proposed laws and resolutions in the U.S. House (HRes.540, HR.3314, HR.3671) and Senate (SRes.632, S.987) call for the United States to move entirely from fossil fuels to clean, renewable electricity and/or all energy. A new bill was just introduced by Rep. Ted Lieu (D-Los Angeles County) and Rep. Jimmy Gomez (D-CA), calling for the U.S. to produce 100 percent of its electric power from renewables by 2035.

Recently, though, some vocal advocates have pushed back, claiming that the only way prices will stay low with large amounts of renewables on the power grid is to use nuclear power, fossil fuels with carbon capture, and biofuels, which they claim are “zero carbon.”

Here is why nuclear, fossils with CCS, and biofuels should be excluded.

All three technologies are opportunity costs. They raise costs to consumers and society, slow solutions to global warming and air pollution by increasing carbon and emissions relative to clean, renewables (thus are not zero carbon), and/or create risks that clean, renewables don’t have.

For example, onshore wind and utility PV are now the cheapest forms of electricity in most countries, including the U.S. New nuclear today costs 4 to 6 times that of new solar or wind to produce the same electricity. Further, a nuclear plant takes 5 to 17 years longer between planning and operation than does a solar or wind farm.

Thus, every dollar spent on nuclear results in 1/5th the energy production and 5 to 17 years more coal and gas burning than if wind or solar were installed instead. This delay and lower energy production from new nuclear condemns millions more to die from air pollution, which today kills 4 to 9 million people worldwide.

By choosing to build several nuclear plants a decade ago that have yet to operate, China suffered an increase in its overall CO2 emissions by 1.4 percent between 2016 and 2017 rather than seeing a decrease of 3.4 percent if it had spent the money on wind and solar instead.

Given that many 100% renewable policies call for a full transition of electricity by 2035, and given the financial and time requirements of nuclear, it is all but impossible for any more than a few new nuclear plant to be in place in by then.

In terms of emissions, nuclear is not zero carbon. A new plant emits 9 to 37 times the carbon emissions over its life as onshore wind, partly due to the fossil fuels used in mining and refining uranium continuously and building the facility but more because coal and gas plants are emitting during the long planning-to-operation time of a nuclear plant.

Evaluation of Nuclear Power as a Proposed Solution to Global Warming, Air Pollution, and Energy Security

Just as importantly, according to the Intergovernmental Panel on Climate Change, there is “robust evidence and high agreement” that nuclear power raises concerns about weapons proliferation, core meltdown, creation and storage of radioactive waste, and land-use degradation from mining. Wind and solar power do not have these concerns.

Next, neither coal nor natural gas with carbon capture and sequestration (CCS) is remotely close to zero carbon. For example, the Petra Nova project in Texas combines a coal plant with CCS. However, a natural gas plant was built just to run the CCS equipment, and when accounting for the actual efficiency, natural gas combustion emissions, CO2 combustion emissions, and methane leaks from mining the gas, the plant reduces only 22 percent of the carbon it was designed to over 20 years – at an additional cost of $4,200/MW. That same investment could have been spent on wind and solar to replace the entire coal plant and 100% of its emissions.

Adding CCS to coal plants also increases air pollution and land degradation by about 25 percent. Finally, the captured CO2 is used for enhancing oil recovery, causing even greater damage to climate and health. Thus, CCS represents an enormous opportunity cost compared with developing wind or solar.

Finally, biofuels for transportation and electricity cause substantial air pollution, climate-relevant emissions, land degradation, and water drawdown compared with truly clean, renewables such as wind and solar.

The only exception may be the use of waste landfill and digester methane if it is used to produce hydrogen for use in a fuel cell, since there is no land-use impact and the methane would be emitted in any case.

For about 30 years, we have been researching climate and air pollution problems and clean, renewable energy plus storage solutions to them. Clean, renewables are energy produced from wind, water, and sunlight (WWS). They include onshore and offshore wind, solar photovoltaics (PV) and heat, concentrated solar power (CSP), geothermal electricity and heat, tidal and wave power, and hydroelectric power. Storage includes electricity, heat, cold, and hydrogen storage.

We have developed plans to transition the world, 139 countries, 50 U.S. states, and 53 towns and cities to 100 percent WWS.

We have found that by electrifying and providing direct heat in all energy sectors with WWS and using storage, the grid can stay stable at low cost throughout the world.
