Perhaps Solar Isn't A Bad Idea After All

Climate Change?

Climate change, also known as global warming, has been a topic of intense debate in the past 50 years. The mainstream narrative claims that human activities, particularly the burning of fossil fuels, have led to an increase in greenhouse gases, resulting in an overall rise in global temperatures. The proponents of this view argue that this temperature rise is causing melting polar ice caps, rising sea levels, and more frequent extreme weather events. They advocate for drastic measures to reduce greenhouse gas emissions, such as transitioning to renewable energy sources and reducing carbon footprints. However, there is also a growing body of evidence and arguments that challenge this narrative. Some people argue that climate change is a natural phenomenon that has occurred throughout Earth's history, and that human activities are not the primary driver of these changes. They point to historical data showing that the Earth's climate has gone through periods of warming and cooling long before humans began burning fossil fuels. They also question the accuracy and reliability of the climate models and data used to support the mainstream narrative. As they always are proven wrong in their predictions. Furthermore, some critics argue that the proposed solutions to climate change, such as transitioning to renewable energy sources, could have unintended consequences and may not be economically viable. They suggest that focusing on adapting to the changing climate, rather than trying to stop it, may be a more practical approach.In summary, climate change is a complex and multifaceted issue with various viewpoints and arguments. While the mainstream narrative emphasizes the role of human activities in causing global warming, there is also a growing body of evidence and counterarguments that challenge this viewpoint.

Nuclear Solution

The amount of water required to produce 1 megawatt-hour (MWh) of energy in a nuclear power plant can vary depending on the specific design and cooling system of the plant. However, on average, a nuclear power plant typically consumes around 10 to 50 cubic meters of water per megawatt-hour (MWh) of electricity generated. Running a 40w tube florescent light for 12 hours requires up to 24 liters of water this way.

That must be an improvement over oil, right? Not so. Estimates for water consumption in vary widely from 2 cubic meters per MWh to 8 cubic meters per MWh. Running a 40w tube florescent light for 12 hours requires as little as one liter of water this way. These values are significantly lower than the water consumption of nuclear power plants, which can range from 10 to 50 cubic meters per MWh.

Solar Energy

Solar energy production generally requires very little water compared to other energy sources. Solar photovoltaic (PV) systems convert sunlight directly into electricity using semiconductor materials, such as silicon, without the need for water-intensive processes like cooling or steam production. This makes solar energy a more sustainable and environmentally friendly option for power generation. However, there are some water requirements associated with the manufacturing, installation, and maintenance of solar PV systems. These include water usage for producing solar panels and cleaning modules to maintain their efficiency. According to a study by the National Renewable Energy Laboratory (NREL), the water consumption for solar PV manufacturing is about 20 liters per MWh, while the water usage for cleaning and maintaining solar PV systems is estimated at one liter per MWh. These values are significantly lower than the water consumption of oil extraction, nuclear power plants, and coal extraction. The mining of materials for solar panels, such as silicon, copper, and aluminum, can involve water usage for various purposes, such as separating minerals from the ore, washing and grading materials, and cooling and cleaning equipment. However, the water requirements for these materials are generally lower than those for coal or oil extraction. In summary, solar energy production generally requires very little water compared to other energy sources. The specific water consumption depends on the materials being mined and the methods used, but overall, solar energy production requires significantly less water than coal, oil, or nuclear power.

Not for Carbon-dioxide but for Water

Yes, I do believe there is climate change but the climate changes over centuries and humanity doesn't have anything to do with it. On the other hand, I do believe in scarce fresh water, at least in terms of access. There are regions where water has always been scarce and what is available has been running out. There are places where fresh water is plentiful and perhaps nuclear is the best deal for them. I submit however that where water is scarce petroleum and so we should start moving toward solar electrical energy.
