Study Notes

Fossil Fuels

Fossil fuels are the world's biggest energy resource, and their production and exploitation depend on various integrated factors of politics and economy.
The documentation and calculation of underground oil and gas reserves are very important for governments' and oil companies' political and environmental grounds.
There are still billions of unrecovered barrels of oil and gas reserves, but challenges in the extraction, production, and distribution processes are real.

Hydraulic Fracturing (Fracking)

Fracking is a process that extracts highly dispersed natural gas and oil by drilling vertically and horizontally through the bedrock.
The fracking process involves drilling a well, fortifying it with steel, and pumping fracking fluid (a mixture of water, sand, and chemicals) to break the rock and release fossil fuels.
Two types of fossil fuels commonly extracted from fracking are oil and natural gas, which are made from the decomposed and chemically transformed remains of ancient plants and animals.
Shale gas is a common source of fossil fuel extracted via fracking, and it is natural gas trapped within shale rock.

Nuclear Energy

Nuclear energy is released from the nucleus of atoms through fission or fusion reactions.
In nuclear power plants, energy is released through fission reactions when large atoms are split apart.
The relationship between energy and mass is represented by Einstein's equation, E = mc², showing that a small amount of mass can generate a large amount of energy.
In a typical fission reaction, large uranium atoms are bombarded with excess energy and particles, causing the uranium nucleus to break apart and release a massive amount of energy.

Solar Energy

Solar energy is energy from the sun that can be converted into thermal or electrical energy.
Solar energy is collected, stored, and converted to usable energy through photovoltaic panels or solar ponds.
Solar energy can be used for heating, cooling, ventilation, transportation, cooking, water treatment, and agriculture.
Solar energy is renewable, available, and clean, but it is also expensive, difficult to store, and dependent on weather conditions.

Biomass Energy

Biomass energy is a renewable and sustainable fuel source derived from recently-living organic materials.
Common sources of biomass energy include wood, animal waste, algae, wood processing waste, and energy crops like corn and soybeans.
Biomass energy can be converted into biofuels and fuel components through processes like burning, pyrolysis, gasification, and fermentation.
Benefits of biomass energy include reducing greenhouse gases, decreasing dependence on imported oil, and being renewable and sustainable when managed responsibly.
Drawbacks of biomass energy include high initial costs, consumption of arable land, and difficulty in storage and transportation.

Hydropower

Hydropower is the kinetic energy naturally produced when water flows from areas of high elevation to areas of low elevation.
Humans use this kinetic energy to produce electricity through hydroelectric power plants.
Hydroelectric power is a clean and renewable energy source, but it can disrupt ecosystems by changing water temperatures and disrupting the natural flow of water.
Efforts have been made to remedy these issues, such as the invention and use of fish ladders.

Geothermal Energy

Geothermal energy is heat energy generated by radioactive decay beneath the Earth's surface.
There are several types of geothermal power plants, including dry steam, flash steam, and binary cycle plants.
Geothermal heat pumps can be used to heat and cool buildings.
Pros of geothermal energy include low operating costs, being a renewable source, and significantly cleaner than fossil fuels.
Cons of geothermal energy include high initial costs, restricted locations, and potential environmental hazards.

Tidal Energy

Tidal energy uses the power of the ocean's tides to produce energy.
There are multiple ways to produce tidal energy, including tidal turbines, tidal barrages, and tidal lagoons.
Pros of tidal energy include being a predictable, inexhaustible, clean, and cheap source of energy.
Cons of tidal energy include being detrimental to marine life, high upfront costs, limited suitable locations, and intermittent nature.

Water

Water is a vital substance that makes life possible on Earth.
The human body is made up of 60% water.
Water regulates the body's temperature through evaporative cooling.
Water's cohesive nature allows it to travel through capillary action.
Water's unique properties include its polarity, high heat capacity, and ability to break chemical bonds through hydrolysis.

Groundwater and Surface Water

We use water from both groundwater and surface water sources.
Groundwater is found in aquifers, which are underground water reservoirs that take a long time to recharge.
Surface water can be overdrawn, causing streams, lakes, and rivers to dry up or fall short of their original levels.
Irrigation is a major use of water, but it can deplete water supplies and create salinized soils.

Ocean Water

Ocean water has a high salinity and contains chemicals like magnesium, sulfate, calcium, and potassium.
Ocean water has a high heat capacity, and its freezing point is lower than that of freshwater due to its higher salinity.
Ocean water density depends on its temperature and salinity, with cold, salty water being denser and sinking to the bottom.
Groundwater plays an important role in the water cycle, natural ecosystems, and land formations on Earth.

Fossil Fuels
