“What are some of the most fertile soils in the world?”
Soil is quite literally one of the bedrocks of human society. And just as Earth’s geography is greatly diverse, so are its soils. Some of the most fertile soils have a high percentage (upwards of 16%) of humus and other nutritious substances. This Chernozem is commonly found in Eastern Europe, Central Asia, and parts of the upper North American Midwest. Because of its recognizable dark color, the word Chernozem comes from the Russian words for black soil (chorny + zemlya).
“Why is broken down organic matter so important to soil quality?”
Organic matter can be found everywhere in the soil. This is typically broken down by plants over time, and when it becomes decomposed enough it will take on very important properties. This structure will be able to hold on to a large amount of nutrients, water, air, and microbes. These give humus great potential to supply plant matter the essentials for life.
Why the Oceans Are Becoming More Acidic
“How are CO2 emissions changing our oceans?”
Every second of every minute of every hour more and more carbon dioxide is being pumped into our atmosphere. Since the carbon intensity in the air will increase, the ocean will absorb more CO2. This larger amounts of this element will react with the H2O in water to form Carbonic Acid (H2CO3) and Hydrogen ions (H+). With a higher volumetric makeup of the latter elements, the oceans will become more acidic, threatening the stability of sea-life. This is Why the Oceans Becoming More Acidic.
Why Offshore Wind in the U.S Might Soon Face Logistic Bottlenecks
“Why is offshore wind in the U.S having logistic problems?”
Offshore wind in the United States is expanding at a rapid pace, particularly in the Northeast. However, since offshore wind turbines tend to extremely large in nature, it takes a large amount of transportation infrastructure such as cranes and heavy trucks for transportation logistics. Due to the limited supply of these components, these projects face the possibility of being stalled. This is Why Offshore Wind in the U.S is Facing Logistic Bottlenecks.
Returns to Scale
“How does cost scale with physical production?”
Cost tends to scale with increased production of a particular element. However, the amount of cost of each item might get larger or smaller! The rate of change of each element to increased production is known as the Returns to Scale. This information is vital for the renewable energy industry, as the optimal deployment size will depend on the best return to scale.
Power Factor Tariff
“Why do some facilities seem to obtain less power than they receive and how are they penalized in a tariff?”
Every facility connected to the grid can receive energy. But the amount that it receives versus what was apparently sent is known as the Power Factor Tariff. The lower the power factor tariff, the more generators and transformers, and other power infrastructure is needed to keep the system running. Since this increases the amount of upkeep needed, utilities implement a Power Factor Tariff to penalize users who draw too much from the grid.
