Renewable Energy

Cogeneration

The simultaneous production of electricity and useful heat from the same energy source, capable of achieving up to 90% efficiency.

Combined Heat and Power (CHP)

Another name for cogeneration, which uses both electricity and heat/steam from the same energy source.

Internal Combustion Engine (ICE)

A conventional vehicle engine that is the least efficient and most polluting.

Battery Electric Vehicle (BEV)

A vehicle that runs entirely on an electric battery/motor without burning gasoline.

Biomass

Organic material used as fuel for cooking or heating, particularly in developing countries.

Biofuels

Renewable energy sources derived from organic materials, including ethanol, biodiesel, and methane.

Fermentation

The process of obtaining ethanol through the breakdown of sugars by microorganisms.

Hydroelectric Power

Electricity generated by water flowing from high to low controlled by dams and reservoirs.

Geothermal Energy

Heat energy from the earth used to create steam for electricity generation.

Hydrogen Fuel Cells

A technology that generates electricity by splitting hydrogen into protons and electrons, combining them with oxygen to produce water vapor.

Passive Solar Energy

Direct use of sunlight for heating without mechanical systems.

Active Solar Energy

The use of mechanical systems to absorb sunlight and convert it into usable heat or electricity.

Tidal Energy

Electricity generated from the movement of water due to tidal forces.

Wave Energy

Energy harnessed from moving air and water, typically from ocean waves.

Visual Pollution

Negative aesthetic impacts caused by certain energy sources, like wind turbines.

Fish Ladder

A structure that allows fish to bypass obstacles like dams during migration.

Anaerobic Bacteria

Microorganisms that break down organic waste in the absence of oxygen, such as in biogas digesters.
