Introduction

Introduction. Energy sources refer to the sources from which energy can be obtained to generate electricity, heat or to power vehicles and machines. Energy sources can be classified into two main categories: renewable and non-renewable energy. Renewable energy sources are replenished naturally and can be used again and again, whereas non-renewable energy sources are finite and will eventually run out. Examples of renewable energy sources include solar, wind, hydro, geothermal, and bioenergy, while examples of non-renewable energy sources include fossil fuels (coal, oil, and natural gas) and nuclear energy..

Renewable Energy Sources. Solar - Solar energy is a renewable energy source that harnesses the power of the sun's rays to generate electricity. Wind - Wind energy is a renewable energy source that harnesses the power of wind to generate electricity. It works by using wind turbines, which are large rotating blades mounted on a tower, to capture the kinetic energy of the wind. Hydro - Hydro energy, also known as hydropower, is a renewable energy source that harnesses the power of moving water to generate electricity. It works by using large dams to store water in reservoirs. When the water is released from the reservoirs, it falls and generates kinetic energy, which is then used to drive turbines that generate electricity..

Renewable Energy Sources Cont’d. Geothermal - Geothermal energy is a renewable energy source that harnesses the heat from the earth's core to generate electricity. It works by tapping into the heat stored in the earth's crust and using it to generate steam, which in turn drives turbines that generate electricity. Bioenergy - Bioenergy is a renewable energy source that harnesses the energy stored in organic matter to generate electricity, heat, and transportation fuels. It works by using organic materials such as crops, wood, and waste as fuel to generate electricity or produce biofuels..

Non-Renewable Energy Sources. Fossil Fuels - Fossil fuels are a type of non-renewable energy source that were formed from the remains of ancient plants and animals that lived millions of years ago. They include coal, oil, and natural gas. Fossil fuels are finite and will eventually run out. They are extracted from the ground and processed to produce electricity, heat, and transportation fuels. Nuclear Energy - Nuclear energy is a non-renewable energy source that harnesses the energy released from atomic nuclei to generate electricity. It works by using nuclear reactors to control the release of energy from the atomic nuclei of elements such as uranium and plutonium. This energy is used to heat water, which produces steam that drives turbines to generate electricity..

Wind turbines on top of a hill. Advantages of Renewable Energy.

Challenges with Renewable Energy. Intermittency (e.g. solar energy not available at night) Initial high cost Limited technology in some areas Requires significant infrastructure.

Advantages of Non-Renewable Energy. Readily available Proven technology Infrastructure already in place.

Challenges with Non-Renewable Energy. Environmental impact (e.g., greenhouse gas emissions) Limited reserves Price volatility.
