Energy is life. Without enough to power human advancement, we would be unable to sustain peace, prosperity, and continued growth. However, energy production comes at a cost. The fossil fuels we have used since the industrial revolution have done a number on the environment, yet some people persist.
Others, however, look for alternatives. Wind, solar, hydroelectric, geothermal, and other energy sources are renewable, drawing power from recurring natural phenomena. These renewables are cleaner than fossil fuels. But each has its attendant challenges. Is it possible that nuclear power can address them? Of course, it's not renewable in the same way, but this article will compare how nuclear power performs against the shortcomings of renewable energy sources.
Nuclear Energy Is Hugely Efficient With A Massive Power Output
Energy is not the only important part of the sustainability movement. Food is crucial. As such, arable land is one of the chief concerns, and several renewable energy sources are big-league land hogs. For example, ten acres of solar panels create around two megawatts of electricity. A wind farm would need 1.5 acres to produce the same amount. In contrast, a series of nuclear power stations would generate 850 megawatts in the same area – an astronomical difference.
The power output of a nuclear reactor is substantially more than that of a coal plant. Furthermore, the fuel source itself is very compact. It would take a ton of coal to yield the same power as a single uranium pellet. Perhaps the greatest selling points of nuclear energy, and its most significant advantages over renewables and fossil fuels, are its tremendous power output in a highly efficient package.
Renewables And Nuclear Can Both Be Expensive
The manufacture, construction, and installation of renewable energy sources demand a significant up-front capital investment. Since several renewables are bound by geography (hydroelectric, for example), they can require energy transport over long distances to reach consumers. Advocates of fossil fuel energy sources often point out the higher price of renewables.
Nuclear power faces a similar issue, at least initially. Building a new nuclear power plant is hugely expensive – much more so than a renewable facility. However, nuclear energy's reliability, longevity, and efficiency lead to excellent long-term pricing. Therefore, it is challenging to claim nuclear power is superior to renewable in regards to cost, since the determination depends on the time frame at issue.
Pollution Plagues the "Green" Energy Movement
Although not often publicized, renewable energy produces a carbon footprint. The manufacturing process of renewable technology releases greenhouse gases and pollutants into the atmosphere. Ironically, many of the resources required to develop a renewable energy plant are derived from fossil fuels. In addition, the final decommissioning of renewable equipment (particularly wind turbines and photovoltaic panels) releases pollutants into the environment.
The use of nitrogen trifluoride and sulfur hexafluoride in producing solar panels is particularly troubling. These are potent greenhouse gases and have thousands of times the global warming effect of carbon dioxide.
This is also true, although to a considerably smaller degree, with nuclear energy. The construction process yields pollution, as does the mining process and the final decommissioning of nuclear facilities. However, the overall pollution produced by a nuclear power station is substantially lower than that produced by traditional fossil fuels.
Popular Renewables Are Unpredictable At Best
Several forms of renewable energy are entirely reliant on the weather. Periods of low wind, cloud cover, and drought all reduce (or eliminate!) the efficacy of their respective renewable plants. Unfortunately, the weather is unpredictable. Therefore, there is no way to match the output of many renewables to consumer demand – it is not always possible to turn it on at will.
Fossil fuels are highly dependable, and nuclear energy shares this quality with them. Weather, season, and other aspects of a fickle climate have no bearing on the reliability of a reactor – within a certain threshold. Fukushima reminded us of nuclear's potential shortcomings when an earthquake damaged its cooling apparatus. However, plants worldwide have since implemented improvements to prevent the same from happening again.
Renewables Can't Be Stored And Require Backup Facilities
Since renewable energy is intermittent, we need to have storage and backup facilities on hand. Currently, storage technologies are available but expensive, and they can damage the environment too. Our batteries cannot store enough power to provide electricity for an entire city. Therefore, most renewable energy relies on fossil fuels as a backup – not ideal for people who want a carbon-free grid.
While battery technology is progressing, it is far from becoming a sustainable support system for renewable energy. Nuclear power is the only clean energy source that can supply a reliable power flow in weather conditions not conducive to renewables. In this regard, combining nuclear and renewable energy is an effective solution. However, some would argue that nuclear power obviates the need for storage altogether.
Nuclear Power Compares Favorably With Renewable Sources' Shortcomings
Comparing nuclear to renewable energy is complex, and people on both sides of the conversation have strong opinions. When it comes down to it, claiming that nuclear power is somehow better than renewables in a general sense is a bridge too far. Nevertheless, while it shares several of the shortcomings of renewables (e.g., high start-up costs and pollution at various points), nuclear power compares favorably in some significant ways (e.g., reliability and efficiency). For these reasons alone, nuclear power deserves serious consideration as a potential tool in our plans for energy sustainability.
Key Takeaways
Call for Backup – Solar panels are great but don't always provide the power you need. If you have them, call your power company to find out what percentage of your backup power is from renewable sources. Sometimes, you can even specify what you want (for a cost).
Be Land Efficient – Wind and solar farms aren't the only farms that take up a lot of arable lands. So what can you do to ensure your food demands make the most out of the soil? Planting your own garden helps, as does avoiding monocropped or unsustainably farmed foods.
Be Tuned In – Pay attention to the weather to help maintain the integrity of the power grid. Try to lower your energy consumption during peak draw periods. Not only will you increase efficiency, but you can save yourself some money.
