Failures of the renewables transition era are insults to taxpayers

Conventional nitrogen fertilizers are made using fossil fuels, primarily natural gas, in a process that turns atmospheric nitrogen and fossil-fuel-derived hydrogen into ammonia. This energy-intensive process, called the Haber-Bosch process, is a major contributor to global greenhouse gas emissions. While phosphorus and potassium fertilizers are made from mined minerals, most agricultural production is reliant on synthetic fertilizers derived from fossil fuels.

Multiple sources estimate that approximately half of the world's food production is dependent on synthetic fertilizers

• Without the use of fertilizers, global crop harvests would be reduced by an estimated 30–50%.

Key statistics on global fertilizer dependency

• Feeds billions: Synthetic nitrogen fertilizers alone are estimated to feed roughly half of the global population. The Haber-Bosch process, which creates these fertilizers, is believed to have enabled the lives of at least 3 to 3.5 billion people today.
• Yield increases: Studies on crop production have attributed anywhere from 30% to over 60% of crop yield increases to synthetic fertilizer inputs, with some analyses suggesting even higher dependency in tropical climates.
• Specific crops: The dependency varies by crop and region. In some countries, a disproportionate amount of fertilizer is used for a single crop, such as maize in the United States, soybeans in Brazil, or palm oil in Malaysia.
• Different nutrients: While nitrogen (N) is the most widely discussed nutrient for food production, fertilizers containing phosphorus (P) and potassium (K) are also critical. Over half of the phosphorus fertilizer used is from nonrenewable sources.

Why is there such a high dependency on fertilizers?

• Population growth: The global population has surged from 1.65 billion in 1900 to over 8 billion today. This growth has been supported by the dramatic increase in food production made possible by synthetic fertilizers.
• Increased yields: Fertilizers provide the essential macronutrients that plants need to grow. Without them, it would be impossible to achieve the high crop yields necessary to sustain the world's population on the existing amount of arable land.
• Land conservation: By intensifying agriculture on existing farmland, fertilizers reduce the need to convert more natural ecosystems into farms.
• Historical trends: Global fertilizer consumption has grown substantially over the last several decades, from 46.3 million metric tons in 1965 to 187.92 million metric tons in 2022. This growth reflects a widespread reliance on modern agricultural methods.

Net-zero ideologies ignore this fundamental truth that wind turbines and solar panels only generate electricity and cannot support the supply chain of products demanded by humanity and, by doing so, risk leaving future generations with scarcity and instability.
