    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

    • 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.
