Energy is a physical property of matter and radiation that can be transformed or converted from one form to another. It is a measure of the ability of a system to do work, and is often defined as the capacity of a physical system to perform work.
It is vital to our existence here on earth, on an indvidual level the human body requires energy to carry out its basic functions, such as breathing, circulating blood, and maintaining body temperature. This energy comes from the food we eat, which our body converts into a form of energy that it can use.
Energy is also the critical component that power our society and underpins all economic development.
Energy is used across all industries and facets of modern life.
- We use energy to generate electricity, which powers our homes, businesses, and industries. The most common sources of electricity generation are fossil fuels (coal, oil, and natural gas), nuclear power, and renewable sources such as solar, wind, hydroelectric, and geothermal.
- We use energy to power cars, trucks, trains, ships, and planes, which are critical for moving people and goods from one place to another. The primary sources of energy for transportation are fossil fuels, although there is increasing interest in electric vehicles and other forms of alternative transportation.
- We use energy to heat and cool buildings, power lighting and appliances, and provide hot water. Energy use in buildings is a significant contributor to greenhouse gas emissions, and there is growing interest in making buildings more energy-efficient and powered by renewable sources of energy.
- We use energy to power manufacturing and other industrial processes, such as refining metals, producing chemicals, and making consumer goods. Fossil fuels are the most common source of energy for industry, although there is growing interest in using renewable energy and improving energy efficiency.
- We use energy to power agricultural machinery, irrigate crops, and transport food from farms to markets. Fossil fuels are the primary source of energy for agriculture, although renewable energy is becoming more common in some parts of the world.
Electricity is part of nature and is our most widely used forms of energy in modern society. Most electricity we use is a secondary energy source produced by converting biomass, coal, natural gas, geothermal energy, nuclear energy, solar energy, and wind energy, into electrical power.
While most electricity generation is done on an industrial scale, individuals have also found innovative ways to produce electricity on a smaller, more localized level. Embracing the potential of renewable energy, many individuals have turned to personal solar panels adorning rooftops, capturing the sun's rays to generate clean, sustainable power. Micro wind turbines gracefully spin atop homes, harnessing the gentlest of breezes to contribute to the energy mix. Some even explore the possibilities of small-scale hydroelectric generators, utilizing the flow of nearby streams or rivers to generate electricity. These individual endeavors not only provide a sense of energy independence but also contribute to a greener, more resilient energy landscape. While the magnitude of their impact may be smaller compared to industrial power plants, these personal electricity production methods represent the power of individuals to be active participants in the journey towards a sustainable future.
Power plants serve as the backbone of our modern society, channeling the incredible power of nature to meet our insatiable energy needs. These monumental structures harness a diverse range of energy sources and convert them into the lifeblood of our electrical grids. Whether it's the combustion of biomass, coal, or natural gas, the extraction of geothermal energy from deep within the Earth, the controlled fission reactions in nuclear power plants, or the captivating dance between solar panels and sunlight, power plants play a pivotal role in generating the electricity that powers our homes, industries, and technological advancements. They stand as remarkable testaments to human ingenuity, transforming nature's resources into a tangible force that illuminates our world and propels our progress.

Renewable Energy Resources
Renewable energy is a source of energy that will replenish naturally over time. Most sources of non-renewable energy are wind, solar and hydro.
- Biofuels: fuels derived from biomass, which can be used to power vehicles, generate electricity, or provide heating. Examples of biofuels include biodiesel, ethanol, and biogas.
- Biopower: electricity generated by burning biomass.
- Biogas: a renewable energy source that is produced by the breakdown of organic matter, such as food waste, animal manure, and sewage. Biogas can be used to generate electricity, heat, and fuel for vehicles.
- Biomass: a renewable energy source that includes organic materials such as wood, crops, and agricultural waste. Biomass can be used to generate electricity, heat, or biofuels.
- Biochar: a type of charcoal that is produced by heating biomass in the absence of oxygen. Biochar can be used to improve soil quality, sequester carbon, and generate energy.
- Geothermal Power Plants: power plants that use geothermal energy to generate electricity. They use the natural heat of the earth's core to produce steam, which is used to drive a turbine and generate electricity. There are three types of geothermal power plants: dry steam, flash steam, and binary cycle.
- Geothermal Heat Pumps: pumps that use the stable temperature of the earth to heat or cool buildings. They work by circulating a fluid through pipes buried in the ground, which absorbs heat from the earth in the winter and transfers heat back into the ground in the summer.
- Direct use of Geothermal Energy: energy that can be used directly for heating or cooling buildings, greenhouses, or industrial processes. In some cases, geothermal energy can be used for agricultural applications, such as heating soil to promote crop growth.
- Enhanced Geothermal Systems: systems that involve drilling deep into the earth's crust to access hot rock and water, which can be used to generate electricity. This technique requires more advanced drilling techniques and technology than traditional geothermal power plants.
- Wave Energy: energy generated by the motion of ocean waves, and can be captured using a variety of devices, such as oscillating water columns, point absorbers, and attenuators. These devices use the motion of waves to drive turbines or generators that produce electricity.
- Tidal Energy: energy generated by the movement of ocean tides, and can be captured using devices such as tidal barrages or tidal turbines. Tidal barrages are similar to dams, and use the rising and falling tides to generate electricity. Tidal turbines are similar to wind turbines, and use the flow of ocean currents to drive generators.
- Ocean Thermal Energy: energy generated by the temperature difference between warm surface water and cold deep water. This temperature difference can be used to drive turbines or generators that produce electricity.
- Salinity Gradient Energy: energy generated by the difference in salt concentration between fresh water and salt water. This difference can be used to drive turbines or generators that produce electricity.
- Ocean Current Energy: energy harnessed from underwater turbines or hydrokinetic energy converters
- Photovoltaic Solar Energy: The most common type of solar energy, which is generated by converting sunlight directly into electricity using solar panels made of semiconductor materials such as silicon. When sunlight hits the solar panels, it creates an electric field that causes electrons to flow, generating a direct current (DC) that can be converted into alternating current (AC) using an inverter.
- Concentrated Solar Power: energy that is harnessed with the help of mirrors or lenses to concentrate sunlight onto a small area, such as a solar thermal collector. This concentrated sunlight is then used to heat a fluid, which can be used to generate steam to drive a turbine and generate electricity.
