Some are of the opinion that it’s too dangerous and poses a threat to the planet. Others think that nuclear energy is a clean and safe alternative to other forms of electricity. Here, we’ve tried to explain the most worrying facts about nuclear energy:

1. Nuclear energy can also be used to build nuclear weapons 

The disastrous effects of the use of nuclear weapons were seen in the bombings of Hiroshima and Nagasaki. Such was the extent of damage that a nuclear weapon is often referred to as a ‘weapon of mass destruction. Certain processes that are used to generate electricity from nuclear energy can also help in creating nuclear weapons. This is why it becomes absolutely necessary to be very responsible with nuclear power.

In recent times, most countries have signed the Nuclear Non-proliferation Treaty. This treaty has never been signed by Israel, India, and Pakistan. Some of the countries that signed the treaty have threatened to make their own nuclear weapons.

2. Nuclear accidents can release radioactive materials in large quantities

There have been several major accidents involving nuclear reactors over the past few decades. One of them happened in Kyshtym in Russia. The accident caused an explosion of waste that was improperly treated. Another major explosion occurred in Chernobyl in Ukraine. It was caused due to the negligence of an improperly trained staff.

All such accidents released large quantities of radioactive materials into the environment. Today, the areas surrounding the damaged reactors have become uninhabitable. This is because long-term exposure even to low doses of radiation can be extremely dangerous. It greatly increases the risk of cancer in those who reside in such areas.

3. Nuclear power plants produce high-level radioactive waste 

Radioactive wastes are produced by nuclear power plants during their operations. These wastes are also produced during the production of electricity. It’s quite a challenge managing and getting rid of such waste. Nearly 97% of the radioactive wastes doesn’t carry the potential for harm. They tend to lose their radioactivity after a few weeks or days.

However, it is the other 3% that poses a real threat. They are high-level radioactive wastes and can retain their radioactivity for centuries. For this reason, they need to be kept in a storage facility far from human settlements. Nuclear power plants across the world produce about 34,000 cubic meters of high-level waste every year.

4. The danger of pollution in underground disposal of nuclear wastes

Almost all the experts agree that nuclear wastes should be buried underground. They must go hundreds or thousands of meters below the ground to ensure safety. Yet, most of the countries are still deciding how their nuclear wastes must be disposed of. Those who are opposed to nuclear power are of the opinion that such methods of disposal can be dangerous.

Radioactive wastes disposed of the underground can leak into the groundwater. Opponents of nuclear power are also not convinced about the safety of underground waste facilities. They still believe that these waste facilities may be unsafe for future generations.

How is wind energy produced?

The generation of electricity through winds is done with the help of turbines. A propeller is driven by the wind and it rotates the rotor of a generator, which produces electricity. To protect the environment and make better use of energy, the wind turbines are grouped in wind farms. Such machines usually have a twenty-year lifespan.

Wind energy vs nuclear energy

In recent times, nuclear power is considered a clean form of energy as compared to other sources of fuel. There was a time when many countries were beginning to consider using more nuclear energy. However, two incidents changed everything. 

One was the Chernobyl nuclear disaster of 1986 and the other was the Fukushima Daiichi nuclear disaster of 2011. Following the Fukushima incident, the German government decided to shut down all nuclear power plants by 2022. Before this decision, the country was a big supplier of nuclear energy.

The world seems to be gradually moving away from using nuclear power. Wind energy is being projected as the form of energy that humans will use in the future. Although the winds cannot be predicted and are inconsistent, they are certainly an affordable source of energy. 

A couple of decades ago, generating energy from the wind and the sun was considered too expensive. Today, the costs involved in generating power from these two energy sources have reduced significantly. 

A study done by Lazard, an investment banking firm provided a good insight in this regard. More than 6 cents are needed to produce one kilowatt-hour of energy from natural gas and coal. Wind costs only around 1.5 cents to produce the same amount of energy.

Spain as a case study

A considerable amount of electricity in Spain comes through wind energy. This form of energy is also a source of wealth and employment for the nation. The country has avoided the imports of fossil fuels to a great extent.

This sector employs more than 30,000 individuals in the country. Spain holds several patents in wind energy. The country also invests more than 150 million Euros every year in research and development. 

Wind energy has lowered the cost of electricity considerably. Spain is one of the world’s first countries to have integrated wind energy into the grid. Today, this European nation has set an example for other countries of the world.

The future of wind energy

It has certainly become a priority for many countries to produce large amounts of risk-free energy. While nuclear energy is clean and efficient, it is quite expensive to generate and carries enormous risks. This is why the French nuclear technology giant, Areva, is considering selling of their company. 

Today, investors are more likely to put their money in risk-free renewable energy sources, such as wind. It is expected to become cheaper in the near future. A time may come when it becomes one of the main sources of energy worldwide.

The post Wind Energy as a Substitute for Nuclear Power appeared first on choosenuclearfree.net.

One cannot ignore the fact that power consumption will continue to increase. It is mainly due to the global demand for energy, coming from industrialized as well as developing nations. If the recent reports are to be believed, nuclear power has become more expensive than solar power. The calculation was made on the basis of installed cost per unit of the capacity of power generation.

Nuclear Energy vs Solar Energy

Nuclear energy is generated by splitting uranium atoms. Upon splitting the atom, two smaller and lighter atoms are formed. The ‘lost’ mass is then transformed into heat used for the production of electricity. A controlled environment is provided for this process by the nuclear power plants. 

Large-scale ecological devastation was caused by accidents at the nuclear power plants of Chernobyl and Fukushima. Otherwise, nuclear power is considered to be relatively environment-friendly and produces fewer emissions. However, nuclear energy relies heavily on uranium mined from the earth and is therefore not sustainable. 

Solar energy is a sustainable source of energy and can provide a stable power supply during the year. It uses photovoltaic modules or solar panels, which utilize the light energy from the sun to generate electricity.

How solar energy can gradually replace nuclear energy

As solar technology advances further, generating power using sunlight will become much more cost-effective. Architects will integrate solar power into the building designs. Hot water systems run by solar energy will be far more economical as compared to the conventional systems. 

The cost of one watt of solar power was over $75 in the late 1970s. It dropped to about $0.60 in 2014. This proves that today’s solar power projects are far more cost-effective. Industry experts have predicted that 50% of the world’s power supply would come from sustainable resources by 2040. 

They have also said that millions of households worldwide would use solar energy in the next few years. This prediction is based on the current usage of solar power in the US and Japan. Germany, China, and Japan also provide financial incentives for those who implement such systems. This has made these countries world leaders in solar deployment.

For planet earth, the sun has always been a reliable source of abundant energy. Today, technologies are available for utilizing solar energy for a variety of purposes. Supply of hot water to households and producing steam for turbines generating energy are two of the best examples.

By now, the entire world has understood the fact that nuclear energy is not sustainable. The only reliable sources of energy are the ones that are sustainable, such as the wind and the sun. At the moment, the cost of producing nuclear power is becoming a cause of concern. 

Under such circumstances, the best alternative is solar energy. As long as the costs involved in producing solar power continue to decrease, there is hope. One cannot rule out the possibility of it replacing nuclear power in the near future.

Experts still ponder over the reasons why a country starts or abandons its nuclear weapons program. Specific explanations on a nation’s motivations for acquiring or not acquiring nuclear arsenal have often been inadequate. However, here are some of the reasons stopping the world from being nuclear free:

1. Dominance

Some countries believe that the only way to achieve a certain degree of dominance is to possess nuclear weapons. This leads them to develop the best possible nuclear arsenals through research and development. 

Any country having nuclear weapons in its possession is capable of inflicting maximum damage on another nation. This belief is used as a tool for keeping their enemy nations at bay. The countries that want to assert their dominance may find it hard to let go of their nuclear weapons.

2. Self-defence

An increased focus on security also becomes a big reason for certain countries to acquire nuclear weapons. They see many countries, especially some of their neighbours, as a threat to their national security. 

When this is their approach, they consider nuclear weapons as powerful means to ward off a possible external aggression. It was a widely accepted fact that countries facing major security problems will pursue nuclear weapons program actively.

3. International status

There is also a perception that possession of nuclear weapons raises the status of a country globally. In the times of cold war, this was acknowledged by many countries. As a result, it served as a motivation for many to pursue their goal of acquiring nuclear arsenal. 

Many countries had ratified the Nuclear Non-Proliferation Treaty. This did not stop some of them from pursuing their nuclear weapons program later on. North Korea and Iran are the examples of such countries.

4. Domestic politics

Countries facing a turmoil in domestic politics sometimes use their nuclear weapons program to divert public attention. There are times when a country’s leadership is under threat following a public outcry. In order to divert the attention of public, the nuclear weapons program may be used by the leadership. 

When such an issue surfaces, negative reactions often come in from the international community. This stirs up nationalist sentiments in the country’s citizens and they forget about their dissent. Thus, the country’s regime may end up strengthening its position after successfully diverting public attention.

According to some experts, a total of thirty-nine countries were once involved in acquiring nuclear weapons. Most of them abandoned their quest of acquiring such weapons over the years. There are primarily two reasons for this. One is the enormous resources needed for making reliable and deliverable nuclear weapons. 

Second is the threat of a large-scale disaster that may happen as a result of using them. In recent times, the number of nations involved in the development of nuclear weapons has been quite low. There is immense hope among the international community that a nuclear-free world would soon become a reality.

On the 11th of March 2011, an earthquake and tsunami hit the eastern part of Japan. This caused a major accident at the Fukushima Daiichi Nuclear Power Plant. The reactors lost their external power source as a result of the earthquake. 

As the tsunami levels went much higher than the plant, the backup diesel generators were disabled. It also damaged the cooling systems of the reactor. As the radiation contaminated larger areas surrounding the plant, almost half a million residents were relocated. 

In order to avoid such disasters in the future, some better Nuclear Energy alternatives are being considered in recent times:

1. Solar Power

Earlier, solar energy systems could be used only by the wealthy owing to their high costs. Today, the costs have reduced considerably. The solar paneling systems are now accessible to a larger population. 

Many of the larger countries of the world have started implementing solar energy, including India and China. Large business organizations are also investing significant amounts in reusable solar systems. It is expected that the use of solar energy systems will increase with further decrease in costs.

2. Hydrogen

Hydrogen is not available naturally on earth in the form of gas, but it can be manufactured. It is one of the elements found in abundance in the earth’s crust. This gas is found in water, coal, and petroleum. As it is lighter than air, it rises into the atmosphere. Hydrogen has the highest amount of energy by weight when compared to any of the common fuels. 

By volume, it has the lowest energy content. Hydrogen is often referred to as a carrier of energy. It, therefore, can be used to store, move, and deliver energy in a form that is convenient to use. Electricity is one such form.

3. Natural Gas

Natural gas is abundantly available in many parts of the world. At the moment, it is available in quantities that can produce sufficient energy for about 250 years. It is currently the third largest source of energy after oil and coal. With the use of appropriate generators, natural gas can be developed for commercial use. 

Considering the dangers of the dependence on nuclear power, natural gas is certainly a good option. When compared with all the other fossil fuels, natural gas is less polluting. The lesser costs involved in its production also makes it a better choice for generating electricity.

4. Wind Energy

Being a free, clean, and renewable source of energy, the wind is greatly favored as an alternative energy source. In fact, wind is a more efficient source of energy than the sun. As wind turbines release lesser carbon dioxide compared to the solar panels, they are more environment-friendly. 

Wind turbines consume less energy and generate more of it. One wind turbine can generate the amount of energy produced by over 48,000 solar panels. Wind energy, therefore, is more cost-efficient than nuclear or solar energy.
