1. Types of Energy and Their Uses

Energy exists in many forms, each suited to specific applications and with varying environmental footprints. The primary categories include fossil fuels, renewable energy sources, and nuclear energy. Understanding these categories provides a foundation for evaluating their roles in current and future energy landscapes.

1.1 Fossil Fuels

Fossil fuels—coal, oil, and natural gas—have historically been the backbone of global energy systems. They are derived from ancient organic matter subjected to geological processes over millions of years.

• Coal: Predominantly used for electricity generation and steel production. It is abundant but highly polluting.
• Oil: Mainly refined into transportation fuels such as gasoline, diesel, and jet fuel, essential for vehicles, aircraft, and ships.
• Natural Gas: Used for heating, electricity generation, and as a feedstock in chemical industries. It is often viewed as a 'bridge fuel' due to relatively lower emissions compared to coal and oil.

Uses: Fossil fuels dominate global energy consumption due to their high energy density and established infrastructure. However, their combustion releases greenhouse gases (GHGs), notably carbon dioxide (CO₂), and pollutants like sulfur dioxide (SO₂) and particulate matter.

1.2 Renewable Energy Sources

Renewables harness natural processes that are replenished rapidly, offering sustainable alternatives to fossil fuels.

• Solar Energy: Captured via photovoltaic (PV) panels and solar thermal collectors. Widely used for electricity and heating.
• Wind Energy: Generated through turbines installed on land (onshore) or at sea (offshore). It is a significant contributor to electricity grids.
• Hydropower: Utilizes flowing water to drive turbines, producing electricity. It is one of the oldest and most established renewable sources.
• Biomass: Organic materials like wood, crop waste, and waste oils converted into heat, electricity, or biofuels.
